  • Incorporating Devise Authentication into an already existing user structure?

    - by Kevin
    I have a fully functional authentication system with a user table that has over fifty columns. It's simple but it does hash encryption with salt, uses email instead of usernames, and has two separate kinds of users with an admin as well. I'm looking to incorporate Devise authentication into my application to beef up the extra parts like email validation, forgetting passwords, remember me tokens, etc... I just wanted to see if anyone has any advice or problems they've encountered when incorporating Devise into an already existing user structure. The essential fields in my user model are: t.string :first_name, :null => false t.string :last_name, :null => false t.string :email, :null => false t.string :hashed_password t.string :salt t.boolean :is_userA, :default => false t.boolean :is_userB, :default => false t.boolean :is_admin, :default => false t.boolean :active, :default => true t.timestamps For reference sake, here's the Devise fields from the migration: t.database_authenticatable :null => false t.confirmable t.recoverable t.rememberable t.trackable That eventually turn into these actual fields in the schema: t.string "email", :default => "", :null => false t.string "encrypted_password", :limit => 128, :default => "", :null => false t.string "password_salt", :default => "", :null => false t.string "confirmation_token" t.datetime "confirmed_at" t.datetime "confirmation_sent_at" t.string "reset_password_token" t.string "remember_token" t.datetime "remember_created_at" t.integer "sign_in_count", :default => 0 t.datetime "current_sign_in_at" t.datetime "last_sign_in_at" t.string "current_sign_in_ip" t.string "last_sign_in_ip" t.datetime "created_at" t.datetime "updated_at" What do you guys recommend? Do I just remove email, hashed_password, and salt from my migration and put in the 5 Devise migration fields and everything will be OK or do I need to do something else?

  • pdfmark for docinfo metadata in pdf is not accepting accented characters in Keywords or Subject

    - by rpilkey
    I am inserting metadata into postscript files with a program, to be distilled to pdf with Adobe Distiller. I am using this code that I grabbed from Thomas Merz's "Web Publishing with Acrobat-PDF": /pdfmark where {pop} {userdict /pdfmark /cleartomark load put} ifelse [ /Title (mot accenté) /Author (mot accenté) /Subject (mot accenté) /Keywords (mot accenté) /DOCINFO pdfmark When you look at the metadata, the accented characters turn into "?" in the Subject and Keyword fields, but not the Title and Author fields. The characters are the same ascii 233 I tried replacing them with octal encoding (\351), which came out the same (Title and Author okay, Subject and Keywords messed up). file encoding is latin-1,unix eol I found a mention on adobe forums, but the answer didn't make sense to me. http://forums.adobe.com/message/1165593 I changed the encoding to utf-8, inserted the characters binarily (in VIM : <Ctrl-v>u00e9), no change. I tried inserting the BOM in a few places, it didn't work. This is with Acrobat Pro 9 I didn't notice this problem with Acrobat Pro 7. Does anybody know of a workaround to get the accented characters into ALL the metadata fields when modifying a postscript file, or tell me if I'm doing it wrong? It seems weird that different fields would not accept the same bytes.

  • Entity Framework. Updating EntityCollection using disconnected objects via navigation property.

    - by yougotiger
    I have a question, much liket this unanswered one. I'm trying to work with the entity framework, and having a tough time getting my foreign tables to update. I have something basically like this in the DB: Incident (table): -ID -other fields Responses (table): -FK:Incident.ID -other fields And and entities that match: Incident (entity) -ID -Other fields -Responses (EntityCollection of Responses via navigation property) Each Incident can have 0 or more responses. In my Webpage, I have a form to allow the user to enter all the details of an Incident, including a list of responses. I can add everything to the database when a new Incident is created, however I'm having difficulty with editing the Incident. When the page loads for edit, I populate the form and then store the responses in the viewstate. When the user changes the list of responses (adds one, deletes one or edits one). I store this back into the viewstate. Then when the user clicks the save button, I'd like to save the changes to the Incident and the Responses back to the DB. I cannot figure out how to get the responses from the detached viewstate into the Incident object so that they can be updated together. Currently when the user clicks save, I'm getting the Incident to edit from the db, making changes to the Incident's fields and then saving it back to the DB. However I can't figure out how to have the detached list of responses from the viewstate attach to the Incident. I have tried the following without success: Clearning the Incident.Responses collection and adding the ones from the viewstate back in: Incident.Responses.Clear() for each objResponse in Viewstate("Responses") Incident.Responses.add(objResponse) next Creating an EntityCollection from my list and then assiging that to the Incident.Responses Incident.Responses = EntityCollectionFromViewstateList Iterating through the responses in Incident.Response and assigning the corresponding object from viewstate: for each ObjResponse in Incident.Responses objResponse = objCorrespondingModifedResonseFromViewState Next These all fail, I'd like to be able to merge the changes into the Inicdent object so that when the BLL calls SaveChanges on the changes to both the Incident and Responses will happen at the same time. Any suggestions? I keep finding lots of stuff about assigning foreign keys (singular), but I haven't found a great solution for doing a set of entities assigned to another entity in this manner.

  • Trying to insert a row using stored procedured with a parameter binded to an expression.

  • ExtJS 4 Chart Axis Display Issue in Chrome

    - by SerEnder
    I've run into an issue while using ExtJS 4.0.7. I'm trying to display a chart with two series on a Numeric/Category Chart. The chart displays correctly in Firefox, but while using Chrome (18.0.1025.142) the x axis labels are either all stacked upon each or else (when using rotate) rendered behind the chart in the specified angle. Any ideas would be appreciated. Screen shot in Firefox: Screen Shot in Chrome: And the code that's used to generate both: Ext.require(['Ext.chart.*']); Ext.onReady(function() { var iChartWidth = 800; // Defines chart width var iChartHeight = 550; // Defines chart height Ext.define('RulesCreatedModel',{ extend:'Ext.data.Model', fields:[ {name:'sHourName', type:'string'}, {name:'User_2', type:'number'}, {name:'User_1', type:'number'}, ] }); var RulesCreatedStore = Ext.create('Ext.data.Store',{ id:'RulesCreatedStore', model:'RulesCreateModel', fields: [ 'sHourName','dayNum','hour','User_2','User_1'], data:[{ 'sHourName':'3pm', 'User_1':82, 'User_2':56 },{ 'sHourName':'4pm', 'User_1':39, 'User_2':44 },{ 'sHourName':'5pm', 'User_1':80, 'User_2':14 },{ 'sHourName':'6pm', 'User_1':55, 'User_2':0, },{ 'sHourName':'7pm', 'User_1':36, 'User_2':0, },{ 'sHourName':'8pm', 'User_1':66, 'User_2':0 },{ 'sHourName':'9pm', 'User_1':39, 'User_2':0, },{ 'sHourName':'10pm', 'User_1':0, 'User_2':0 },{ 'sHourName':'11pm', 'User_1':0, 'User_2':0 },{ 'sHourName':'12am', 'User_1':0, 'User_2':0 },{ 'sHourName':'1am', 'User_1':0, 'User_2':0 },{ 'sHourName':'2am', 'User_1':0, 'User_2':0 },{ 'sHourName':'3am', 'User_1':0, 'User_2':0 },{ 'sHourName':'4am', 'User_1':0, 'User_2':0 },{ 'sHourName':'5am', 'User_1':0, 'User_2':0 },{ 'sHourName':'6am', 'User_1':0, 'User_2':0 },{ 'sHourName':'7am', 'User_1':0, 'User_2':1 },{ 'sHourName':'8am', 'User_1':0, 'User_2':99 },{ 'sHourName':'9am', 'User_1':0, 'User_2':28 },{ 'sHourName':'10am', 'User_1':0, 'User_2':28 },{ 'sHourName':'11am', 'User_1':0, 'User_2':153 },{ 'sHourName':'12pm', 'User_1':0, 'User_2':58 },{ 'sHourName':'1pm', 'User_1':0, 'User_2':42 },{ 'sHourName':'2pm', 'User_1':20, 'User_2':10 }] }); Ext.create('Ext.chart.Chart',{ id: 'RulesWrittenChart', renderTo: 'StatCharts_Display', width: iChartWidth, height: iChartHeight, animate: true, store: RulesCreatedStore, axes: [{ type: 'Numeric', position: 'left', fields: ['User_2','User_1'], title: 'Rules Written', grid: true },{ type: 'Category', position: 'bottom', fields: ['sHourName'], title: 'Hour', grid: false, label: { rotate: { degrees: 315 } } }], series: [{ type: 'line', axis: 'left', xField: 'sHourName', yField: 'User_2', highlight: { size: 3, radius: 3 } },{ type: 'line', axis: 'left', xField: 'sHourName', yField: 'User_1', highlight: { size: 3, radius: 3 } }] }); });

  • How to create more complex Lucene query strings?

    - by boris callens
    This question is a spin-off from this question. My inquiry is two-fold, but because both are related I think it is a good idea to put them together. How to programmatically create queries. I know I could start creating strings and get that string parsed with the query parser. But as I gather bits and pieces of information from other resources, there is a programattical way to do this. What are the syntax rules for the Lucene queries? --EDIT-- I'll give a requirement example for a query I would like to make: Say I have 5 fields: First Name Last Name Age Address Everything All fields are optional, the last field should search over all the other fields. I go over every field and see if it's IsNullOrEmpty(). If it's not, I would like to append a part of my query so it adds the relevant search part. First name and last name should be exact matches and have more weight then the other fields. Age is a string and should exact match. Address can varry in order. Everything can also varry in order. How should I go about this?

  • django: control json serialization

    - by abolotnov
    Is there a way to control json serialization in django? Simple code below will return serialized object in json: co = Collection.objects.all() c = serializers.serialize('json',co) The json will look similar to this: [ { "pk": 1, "model": "picviewer.collection", "fields": { "urlName": "architecture", "name": "\u0413\u043e\u0440\u043e\u0434 \u0438 \u0430\u0440\u0445\u0438\u0442\u0435\u043a\u0442\u0443\u0440\u0430", "sortOrder": 0 } }, { "pk": 2, "model": "picviewer.collection", "fields": { "urlName": "nature", "name": "\u041f\u0440\u0438\u0440\u043e\u0434\u0430", "sortOrder": 1 } }, { "pk": 3, "model": "picviewer.collection", "fields": { "urlName": "objects", "name": "\u041e\u0431\u044a\u0435\u043a\u0442\u044b \u0438 \u043d\u0430\u0442\u044e\u0440\u043c\u043e\u0440\u0442", "sortOrder": 2 } } ] You can see it's serializing it in a way that you are able to re-create the whole model, shall you want to do this at some point - fair enough, but not very handy for simple JS ajax in my case: I want bring the traffic to minimum and make the whole thing little clearer. What I did is I created a view that passes the object to a .json template and the template will do something like this to generate "nicer" json output: [ {% if collections %} {% for c in collections %} {"id": {{c.id}},"sortOrder": {{c.sortOrder}},"name": "{{c.name}}","urlName": "{{c.urlName}}"}{% if not forloop.last %},{% endif %} {% endfor %} {% endif %} ] This does work and the output is much (?) nicer: [ { "id": 1, "sortOrder": 0, "name": "????? ? ???????????", "urlName": "architecture" }, { "id": 2, "sortOrder": 1, "name": "???????", "urlName": "nature" }, { "id": 3, "sortOrder": 2, "name": "??????? ? ?????????", "urlName": "objects" } ] However, I'm bothered by the fast that my solution uses templates (an extra step in processing and possible performance impact) and it will take manual work to maintain shall I update the model, for example. I'm thinking json generating should be part of the model (correct me if I'm wrong) and done with either native python-json and django implementation but can't figure how to make it strip the bits that I don't want. One more thing - even when I restrict it to a set of fields to serialize, it will keep the id always outside the element container and instead present it as "pk" outside of it.

  • copy entire row (without knowing field names)

    - by Todd Webb
    Using SQL Server 2008, I would like to duplicate one row of a table, without knowing the field names. My key issue: as the table grows and mutates over time, I would like this copy-script to keep working, without me having to write out 30+ ever-changing fields, ugh. Also at issue, of course, is IDENTITY fields cannot be copied. My code below does work, but I wonder if there's a more appropriate method than my thrown-together text string SQL statement? So thank you in advance. Here's my (yes, working) code - I welcome suggestions on improving it. Todd alter procedure spEventCopy @EventID int as begin -- VARS... declare @SQL varchar(8000) -- LIST ALL FIELDS (*EXCLUDE* IDENTITY FIELDS). -- USE [BRACKETS] FOR ANY SILLY FIELD-NAMES WITH SPACES, OR RESERVED WORDS... select @SQL = coalesce(@SQL + ', ', '') + '[' + column_name + ']' from INFORMATION_SCHEMA.COLUMNS where TABLE_NAME = 'EventsTable' and COLUMNPROPERTY(OBJECT_ID('EventsTable'), COLUMN_NAME, 'IsIdentity') = 0 -- FINISH SQL COPY STATEMENT... set @SQL = 'insert into EventsTable ' + ' select ' + @SQL + ' from EventsTable ' + ' where EventID = ' + ltrim(str(@EventID)) -- COPY ROW... exec(@SQL) -- REMEMBER NEW ID... set @EventID = @@IDENTITY -- (do other stuff here) -- DONE... -- JUST FOR KICKS, RETURN THE SQL STATEMENT SO I CAN REVIEW IT IF I WISH... select EventID = @EventID, SQL = @SQL end

  • help me to choose between two software architecture

  • Django repeating vars/cache issue?

    - by Mark
    I'm trying to build a better/more powerful form class for Django. It's working well, except for these sub-forms. Actually, it works perfectly right after I re-start apache, but after I refresh the page a few times, my HTML output starts to look like this: <input class="text" type="text" id="pickup_addr-pickup_addr-pickup_addr-id-pickup_addr-venue" value="" name="pickup_addr-pickup_addr-pickup_addr-pickup_addr-venue" /> The pickup_addr- part starts repeating many times. I was looking for loops around the prefix code that might have cause this to happen, but the output isn't even consistent when I refresh the page, so I think something is getting cached somewhere, but I can't even imagine how that's possible. The prefix car should be reset when the class is initialized, no? Unless it's somehow not initializing something? class Form(object): count = 0 def __init__(self, data={}, prefix='', action='', id=None, multiple=False): self.fields = {} self.subforms = {} self.data = {} self.action = action self.id = fnn(id, 'form%d' % Form.count) self.errors = [] self.valid = True if not empty(prefix) and prefix[-1:] not in ('-','_'): prefix += '-' for name, field in inspect.getmembers(self, lambda m: isinstance(m, Field)): if name[:2] == '__': continue field_name = fnn(field.name, name) field.label = fnn(field.label, humanize(field_name)) field.name = field.widget.name = prefix + field_name + ife(multiple, '[]') field.id = field.auto_id = field.widget.id = ife(field.id==None, 'id-') + prefix + fnn(field.id, field_name) + ife(multiple, Form.count) field.errors = [] val = fnn(field.widget.get_value(data), field.default) if isinstance(val, basestring): try: val = field.coerce(field.format(val)) except Exception, err: self.valid = False field.errors.append(escape_html(err)) field.val = self.data[name] = field.widget.val = val for rule in field.rules: rule.fields = self.fields rule.val = field.val rule.name = field.name self.fields[name] = field for name, form in inspect.getmembers(self, lambda m: ispropersubclass(m, Form)): if name[:2] == '__': continue self.subforms[name] = self.__dict__[name] = form(data=data, prefix='%s%s-' % (prefix, name)) Form.count += 1 Let me know if you need more code... I know it's a lot, but I just can't figure out what's causing this!

  • About conversion of simplexmlobject to array.

    - by Rishi2686
    Hi guys, I tried the way you told but really messing up on some points. I am getting array fields but when it comes to children nodes, i go off the track. here giving single user's simplexml object only : SimpleXMLElement Object ( [users] = SimpleXMLElement Object ( [@attributes] = Array ( [type] = array ) [user] = Array ( [0] = SimpleXMLElement Object ( [id] = 1011 [name] = saroj [location] = SimpleXMLElement Object ( ) [description] = SimpleXMLElement Object ( ) [profile_image_url] = http://a5.example.com/profile_images/img_normal.jpg [url] = SimpleXMLElement Object ( ) [created_at] = Fri Apr 16 17:04:13 +0000 2010 [status] = SimpleXMLElement Object ( [created_at] = Wed May 26 02:56:03 +0000 2008 [id] = 1473 [text] = hi enjoying here! [in_reply_to_user_id] = SimpleXMLElement Object ( ) ) ) To get this into array I am writing code as below : $users = simplexml_load_string($xml); $arr2 = array(); foreach($users->users->user as $user) { $arr1 = array(); foreach($user as $k=>$v) { $arr1[$k] = (string) $v; } $arr2[] = $arr1; } I am getting all the fields as expected from arr2() instead of the status field which contains an array (imp: id & created_at fields repeated), it gives just key as status. While trying differently i get some of the fields of status array too. Please help me on this, i am really trying it from last two days. Help will be greatly appreciated.

  • Commercial web application--scalable database design

    - by Rob Campbell
    I'm designing a set of web apps to track scientific laboratory data. Each laboratory has several members, each of whom will access both their own data and that of their laboratory as a whole. Many typical queries will thus be expected to return records of multiple members (e.g. my mouse, joe's mouse and sally's mouse). I think I have the database fairly well normalized. I'm now wondering how to ensure that users can efficiently access both their own data and their lab's data set when it is mixed among (hopefully) a whole ton of records from other labs. What I've come up with so far is that most tables will end with two fields: user_id and labgroup_id. The WHERE clause of any SELECT statement will include the appropriate reference to one of the id fields ("...WHERE 'labroup_id=n..." or "...WHERE user_id=n..."). My questions are: Is this an approach that will scale to 10^6 or more records? If so, what's the best way to use these fields in a query so that it most efficiently searches the relevant subset of the database? e.g. Should the first step in querying be to create a temporary table containing just the labgroup's data? Or will indexing using some combination of the id, user_id, and labroup_id fields be sufficient at that scale? I thank any responders very much in advance.

  • How to send XML and other post parameters via cURL in PHP

    - by tomaszs
    Hello. I've used code below to send XML to my REST API. $xml_string_data contains proper XML, and it is passed well to mypi.php: //set POST variables $url = 'http://www.server.cu/mypi.php'; $fields = array( 'data'=>urlencode($xml_string_data) ); //url-ify the data for the POST $fields_string = ""; foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; } rtrim($fields_string,'&'); echo $fields_string; //open connection $ch = curl_init(); curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch,CURLOPT_POST,count($fields)); curl_setopt($ch,CURLOPT_POSTFIELDS,$fields_string); curl_setopt($ch,CURLOPT_HTTPHEADER,array ( "Expect: " )); //execute post $result = @curl_exec($ch); But when I've added other field: $fields = array( 'method' => "methodGoPay", 'data'=>urlencode($xml_string_data) ); It stopped to work. On the mypi.php I don't recieve any more POST parameters at all! Could you you please tell me what to do to send XML and other post parameters in one cURL request? Please don't suggest using any libraries, I wan't to acomplish it in plain PHP.

  • Dealing With Java Default Level Access Specifiers

    - by Tom Tresansky
    I've seen some code in a project recently where some fields in a couple classes have been using the default access modifier without good reason to. It almost looks like a case of "oops, forgot to make these private". Since the classes are used almost exclusively outside of the package they are defined in, the fields are not visible from the calling code, and are treated as private. So the mistake/oversight would not be very noticeable. However, encapsulation is broken. If I wanted to add a new class to the existing package, I could then mess with internal data in objects using fields with default access. So, my questions: Are there any best practices concerning default access specifiers that I should be aware of? Anything that would help prevent this type of accident from re-occurring? Are are any annotations which might say something to the effect of "I really meant for these to be default access"? Using CheckStyle, or any other Eclipse plugins, is there any way to flag instances of default fields, or disallow any not accompanied by, say, a "//default access" comment trailing them?

  • An Erroneous SQL Query makes browser hang until script timeout exceeded

    - by Jimbo
    I have an admin page in a Classic ASP web application that allows the admin user to run queries against the database (SQL Server 2000) Whats really strange is that if the query you send has an error in it (an invalid table join, a column you've forgotten to group by etc) the BROWSER hangs (CPU usage goes to maximum) until the SERVER script timeout is exceeded and then spits out a timeout exceeded error (server and browser are on different machines, so not sure how this happens!) I have tried this in IE 8 and FF 3 with the same result. If you run that same query (with errors) directly from SQL Enterprise Manager, it returns the real error immediately. Is this a security feature? Does anyone know how to turn it off? It even happens when the connection to the database is using 'sa' credentials so I dont think its a security setting :( Dim oRS Set oRS = Server.CreateObject("ADODB.Recordset") oRS.ActiveConnection = sConnectionString // run the query - this is for the admin only so doesnt check for sql safe commands etc. oRS.Open Request.Form("txtSQL") If Not oRS.EOF Then // list the field names from the recordset For i = 0 to oRS.Fields.Count - 1 Response.Write oRS.Fields(i).name & "&nbsp;" Next // show the data for each record in the recordset While Not oRS.EOF For i = 0 to oRS.Fields.Count - 1 Response.Write oRS.Fields(i).value & "&nbsp;" Next Response.Write "<br />" oRS.Movenext() Wend End If

  • How to face observable object containing an observable field

    - by iseek
    Hello, I need a hint concerning MVC and Observer-Pattern. For example a model contains the classes "Address" and "Person". The Address class contains the fields street:String, zipcode:String, location:String. Whereas the Person class contains the fields name:String, firstName:String, address:Address. My approach so far looks something like this: Both, Address and Person are observable. If one of their setters is being called, I validate whether the current value and new value differ. Only in this case an update event is fired. The event contains the source, the name of the changed field, the old and the new value. The class for the view contains text fields to display and edit the information of a person: name, firstname, street, zipcode, location. It knows the Person model and is an subscribed observer for the person. So it gets the update events from the person object. My questions concerns the address field from type Address in the person class, since an address is observable on its own. If the view gets an update event from person when a new address has been set, I can update all of the address related fields in the view. But what if a field of the address changes? Should the view also register for update events from the address? Any hints about common design approaches would be appreciated. Greetings.

  • Only want "Required field" error to appear ONCE in ASP.NET Validation Summary

    - by PapillonUK
    I have a form with several fields with a RequiredFieldValidator on them. If any of these fields are not filled in I only want the message "Please enter the items marked with an asterisk" to appear once in the ValidationSummary control and an asterisk to appear next to each field. I have done this using the method here. i.e. by setting Text to "*" and ValidationSummary.HeaderText to my message. Great, but no cigar as I also have other fields with other validators e.g. a RegEx for an Email field. This means that if all the required fields are entered but the email is incorrect, the ValidationSummary with "Please enter the items marked with an asterisk" will appear along with the message for the invalid email. Crap! I then tried using a ValidationGroup called "ReqField" and have a one ValidationSummary for this group (with my HeaderText) and another for the other validators, but alas, my Submit button only allows one ValidationGroup to be triggered upon the click event. Does anyone have any ideas as to how I can get this to work? Thanks in adavnce.

  • lambda expressions in VB.NET... what am I doing wrong???

    - by Bob
    when I run this C# code, no problems... but when I translate it into VB.NET it compiles but blows due to 'CompareString' member not being allowed in the expression... I feel like I'm missing something key here... private void PrintButton_Click(object sender, EventArgs e) { if (ListsListBox.SelectedIndex > -1) { //Context using (ClientOM.ClientContext ctx = new ClientOM.ClientContext(UrlTextBox.Text)) { //Get selected list string listTitle = ListsListBox.SelectedItem.ToString(); ClientOM.Web site = ctx.Web; ctx.Load(site, s => s.Lists.Where(l => l.Title == listTitle)); ctx.ExecuteQuery(); ClientOM.List list = site.Lists[0]; //Get fields for this list ctx.Load(list, l => l.Fields.Where(f => f.Hidden == false && (f.CanBeDeleted == true || f.InternalName == "Title"))); ctx.ExecuteQuery(); //Get items for the list ClientOM.ListItemCollection listItems = list.GetItems( ClientOM.CamlQuery.CreateAllItemsQuery()); ctx.Load(listItems); ctx.ExecuteQuery(); // DOCUMENT CREATION CODE GOES HERE } MessageBox.Show("Document Created!"); } } but in VB.NET code this errors due to not being allowed 'CompareString' members in the ctx.Load() methods... Private Sub PrintButton_Click(sender As Object, e As EventArgs) If ListsListBox.SelectedIndex > -1 Then 'Context Using ctx As New ClientOM.ClientContext(UrlTextBox.Text) 'Get selected list Dim listTitle As String = ListsListBox.SelectedItem.ToString() Dim site As ClientOM.Web = ctx.Web ctx.Load(site, Function(s) s.Lists.Where(Function(l) l.Title = listTitle)) ctx.ExecuteQuery() Dim list As ClientOM.List = site.Lists(0) 'Get fields for this list ctx.Load(list, Function(l) l.Fields.Where(Function(f) f.Hidden = False AndAlso (f.CanBeDeleted = True OrElse f.InternalName = "Title"))) ctx.ExecuteQuery() 'Get items for the list Dim listItems As ClientOM.ListItemCollection = list.GetItems(ClientOM.CamlQuery.CreateAllItemsQuery()) ctx.Load(listItems) ' DOCUMENT CREATION CODE GOES HERE ctx.ExecuteQuery() End Using MessageBox.Show("Document Created!")

  • help me to choose between two designs

    // stupid title, but I could not think anything smarter I have a code (see below, sorry for long code but it's very-very simple): namespace Option1 { class AuxClass1 { string _field1; public string Field1 { get { return _field1; } set { _field1 = value; } } // another fields. maybe many fields maybe several properties public void Method1() { // some action } public void Method2() { // some action 2 } } class MainClass { AuxClass1 _auxClass; public AuxClass1 AuxClass { get { return _auxClass; } set { _auxClass = value; } } public MainClass() { _auxClass = new AuxClass1(); } } } namespace Option2 { class AuxClass1 { string _field1; public string Field1 { get { return _field1; } set { _field1 = value; } } // another fields. maybe many fields maybe several properties public void Method1() { // some action } public void Method2() { // some action 2 } } class MainClass { AuxClass1 _auxClass; public string Field1 { get { return _auxClass.Field1; } set { _auxClass.Field1 = value; } } public void Method1() { _auxClass.Method1(); } public void Method2() { _auxClass.Method2(); } public MainClass() { _auxClass = new AuxClass1(); } } } class Program { static void Main(string[] args) { // Option1 Option1.MainClass mainClass1 = new Option1.MainClass(); mainClass1.AuxClass.Field1 = "string1"; mainClass1.AuxClass.Method1(); mainClass1.AuxClass.Method2(); // Option2 Option2.MainClass mainClass2 = new Option2.MainClass(); mainClass2.Field1 = "string2"; mainClass2.Method1(); mainClass2.Method2(); Console.ReadKey(); } } What option (option1 or option2) do you prefer ? In which cases should I use option1 or option2 ? Is there any special name for option1 or option2 (composition, aggregation) ?

  • Can a T-SQL variable represent an entire row?

    - by elbillaf
    I'm coding for MS SQL Server 10. I have two databases that contain dozens of tables. Each table in one database contains a table with the same name in the other database. Tables with the same name have identical format (fields and data types). The contents of the two tables are similar but not identical. I need to update one based on changes made to the other, but only under certain circumstances. I think I want to use a cursor for this, but I can't find a good example to go by. So far, the MSDN examples are reading one field at a time into a variable. I do need to be able to read /modify two fields which are identical in each table, but I gotta believe there's something less tedious than declaring variables for every field of every table. I would like to be able to FETCH an entire row, check a couple of fields and then make a decision of whether I want to write the entire row to the other table after changing two fields - but do I have to declare variables for EVERY field I want to fetch / write? There's no way to just FETCH an entire row and write an entire row?

  • How can I improve this SQL to avoid several problems with its results?

    - by Josh Curren
    I am having some problems with trying to search. Currently this will only return results that have at least 1 row in the maintenance_parts table. I would like it to return results even if there are 0 parts rows. My second problem is that when you search for a vehicle and it should return multiple results (multiple maintenance rows) it will only return 1 result for that vehicle. Some Background Info: The user has 2 fields to fill out. The fields are vehicle and keywords. The vehicle field is meant to allow searching based on the make, model, VIN, truck number (often is 2 - 3 digits or a letter prefix followed by 2 digits), and a few other fields that belong to the truck table. The keywords are meant to search most fields in the maintenance and maintenance_parts tables (things like the description of the work, parts name, parts number). The maintenance_parts table can contain 0, 1, or more rows for each maintenance row. The truck table contains exactly 1 row for every maintenance row. A truck can have multiple maintenance records. "SELECT M.maintenance_id, M.some_id, M.type_code, M.service_date, M.mileage, M.mg_id, M.mg_type, M.comments, M.work_done, MATCH( M.comments, M.work_done) AGAINST( '$keywords' ) + MATCH( P.part_num, P.part_desc, P.part_ref) AGAINST( '$keywords' ) + MATCH( T.truck_number, T.make, T.model, T.engine, T.vin_number, T.transmission_number, T.comments) AGAINST( '$vehicle' ) AS score FROM maintenance M, maintenance_parts P, truck T WHERE M.maintenance_id = P.maintenance_id AND M.some_id = T.truck_id AND M.type_code = 'truck' AND ( (MATCH( T.truck_number, T.make, T.model, T.engine, T.vin_number, T.transmission_number, T.comments) AGAINST( '$vehicle' ) OR T.truck_number LIKE '%$vehicle%') OR MATCH( P.part_num, P.part_desc, P.part_ref) AGAINST( '$keywords' ) OR MATCH( M.comments, M.work_done) AGAINST( '$keywords' ) ) AND M.status = 'A' GROUP BY maintenance_id ORDER BY score DESC, maintenance_id DESC LIMIT 0, $limit"

  • How can I join 3 tables with mysql & php?

    - by steven
    check out the page [url]http://www.mujak.com/test/test3.php[/url] It pulls the users Post,username,xbc/xlk tags etc which is perfect... BUT since I am pulling information from a MyBB bulletin board system, its quite different. When replying, people are are allowed to change the "Thread Subject" by simplying replying and changing it. I dont want it to SHOW the changed subject title, just the original title of all posts in that thread. By default it repies with "RE:thread title". They can easily edit this and it will show up in the "Subject" cell & people wont know which thread it was posted in because they changed their thread to when replying to the post. So I just want to keep the orginial thread title when they are replying. Make sense~?? Tables:mybb_users Fields:uid,username Tables:mybb_userfields Fields:ufid Tables:mybb_posts Fields:pid,tid,replyto,subject,ufid,username,uid,message Tables:mybb_threads Fields:tid,fid,subject,uid,username,lastpost,lastposter,lastposteruid I haev tried multiple queries with no success: $result = mysql_query(" SELECT * FROM mybb_users LEFT JOIN (mybb_posts, mybb_userfields, mybb_threads) ON ( mybb_userfields.ufid=mybb_posts.uid AND mybb_threads.tid=mybb_posts.tid AND mybb_users.uid=mybb_userfields.ufid ) WHERE mybb_posts.fid=42"); $result = mysql_query(" SELECT * FROM mybb_users LEFT JOIN (mybb_posts, mybb_userfields, mybb_threads) ON ( mybb_userfields.ufid=mybb_posts.uid AND mybb_threads.tid=mybb_posts.tid AND mybb_users.uid=mybb_posts.uid ) WHERE mybb_threads.fid=42"); $result = mysql_query(" SELECT * FROM mybb_posts LEFT JOIN (mybb_userfields, mybb_threads) ON ( mybb_userfields.ufid=mybb_posts.uid AND mybb_threads.tid=mybb_posts.tid ) WHERE mybb_posts.fid=42");

  • Sqlite3 INSERT INTO Question × 377

    - by user316717
    Hi, My 1st post. I am creating an exercise app that will record the weight used and the number of "reps" the user did in 4 "Sets" per day over a period of 7 days so the user may view their progress. I have built the database table named FIELDS with 2 columns ROW and FIELD_DATA and I can use the code below to load the data into the db. But the code has a sql statement that says, INSERT OR REPLACE INTO FIELDS (ROW, FIELD_DATA)VALUES (%d, '%@'); When I change the statment to: INSERT INTO FIELDS (ROW, FIELD_DATA)VALUES (%d, '%@'); Nothing happens. That is no data is recorded in the db. Below is the code: #define kFilname @"StData.sqlite3" - (NSString *)dataFilePath { NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; return [documentsDirectory stringByAppendingPathComponent:kFilname]; } -(IBAction)saveData:(id)sender; { for (int i = 1; i <= 8; i++) { NSString *fieldName = [[NSString alloc]initWithFormat:@"field%d", i]; UITextField *field = [self valueForKey:fieldName]; [fieldName release]; NSString *insert = [[NSString alloc] initWithFormat: @"INSERT OR REPLACE INTO FIELDS (ROW, FIELD_DATA) VALUES (%d, '%@');",i, field.text]; // sqlite3_stmt *stmt; char *errorMsg; if (sqlite3_exec (database, [insert UTF8String], NULL, NULL, &errorMsg) != SQLITE_OK) { // NSAssert1(0, @"Error updating table: %s", errorMsg); sqlite3_free(errorMsg); } } sqlite3_close(database); } So how do I modify the code to do what I want? It seemed like a simple sql statement change at first but obviously there must be more. I am new to Objective-C and iPhone programming. I am not new to using sql statements as I have been creating web apps in ASP for a number of years. Any help will be greatly appreciated, this is driving me nuts! Thanks in advance Dave
