  • set a default saving data in a selection box in HABTM model

    - by vincent low
    here is my problem which in my system. my system allow user to add event, which include date, time, places. In the other hand, user are allow to choose the "Event sharing to" some of other user. So i successful to created and share to other user, when the user login which are being choose to share with the event, he is able to view for that particular event. But the problem is, when user add the event, he must choose for his own name also in the select box. If not he will be unable to read the event that he had created. So i need to save a default data to my model, which is whenever the user got choose the sharing event or not, it also will save the data to his user id. here is my code for select box, what can i edit and do to let it set a default saving value which is always save with the user own data?? input('User',array( 'label' = 'Select Related Potential', 'options' = $users, //'id'='user', 'style'='width:250px;height:100px', //'selected' = $ownUserId )); ? i try to solve by adding 1 more row to the add.ctp, but the permission just set to the own user who created it, the other user i choose is unable to read. $form-input('User',array( 'label' = 'Select Related Potential', 'options' = $users, //'id'='user', 'style'='width:250px;height:100px', 'selected' = $ownUserId )); $form-input('User',array('type'='hidden','value'=$ownUserId));

  • Mapping composite foreign keys in a many-many relationship, with overlapping components.

    - by Kirk Broadhurst
    I have a Page table and a View table. There is a many-many relationship between these two via a PageView table. Unfortunately all of these tables need to have composite keys (for business reasons). Page has a primary key of (PageCode, Version), View has a primary key of (ViewCode, Version). PageView obviously enough has PageCode, ViewCode, and Version. The FK to Page is (PageCode, Version) and the FK to View is (ViewCode, Version) Makes sense and works, but when I try to map this in Entity framework I get Error 3021: Problem in mapping fragments...: Each of the following columns in table PageView is mapped to multiple conceptual side properties: PageView.Version is mapped to (PageView_Association.View.Version, PageView_Association.Page.Version) So clearly enough, EF is having a complain about the Version column being a common component of the two foreign keys. Obviously I could create a PageVersion and ViewVersion column in the join table, but that kind of defeats the point of the constraint, i.e. the Page and View must have the same Version value. Has anyone encountered this, and is there anything I can do get around it? Thanks!

  • XMLHttpRequest open() returning access denied

    - by rjovic
    Hi! I have problem with xhr open() method. My code follows : var xmlhttp=false; if(!xmlhttp) try { xmlhttp=new XMLHttpRequest(); } catch(e) { xmlhttp=false; } function returnPage(url) { if(!xmlhttp) return alert("Your browser doesn't seem to support XMLHttpRequests."); xmlhttp.open("GET",url,true); xmlhttp.onreadystatechange=function() { if(xmlhttp.readyState!=4) return; if(!xmlhttp.status||xmlhttp.status==200) alert(xmlhttp.responseText); else alert("Request failed!"); }; //onreadystatechange xmlhttp.send(null); } Call : <a href='#' onclick="returnPage('http://www.something.com'); return false;">Link 1</a></p> I'm using IE8 (because I'm building web slice) and I received error "Access denied". I found on the Internet that problem is that XHR isn't working across different domains, but I used code from Firefox Add-on which is working OK. And that add-on and "my" code (which are the same) are calling the same page. How that add-on have access and my code not?

  • .NET MVC custom routing with empty parameters

    - by user135498
    Hi All, I have a .net mvc with the following routes: routes.Add(new Route( "Lookups/{searchtype}/{inputtype}/{firstname}/{middlename}/{lastname}/{city}/{state}/{address}", new RouteValueDictionary( new { controller = "Lookups", action = "Search", firstname = (string)null, middlename = (string)null, lastname = (string)null, city = (string)null, state = (string)null, address = (string)null, SearchType = SearchType.PeopleSearch, InputType = InputType.Name }), new MvcRouteHandler()) ); routes.Add(new Route( "Lookups/{searchtype}/{inputtype}", new RouteValueDictionary( new { controller = "Lookups", action = "Search", firstname = "", middlename = "", lastname = "", city = "", state = "", address = "" }), new MvcRouteHandler()) ); routes.Add(new Route( "Lookups/{searchtype}/{inputtype}", new RouteValueDictionary( new { controller = "Lookups", action = "Search", firstname = "", middlename = "", lastname = "", city = "", state = "", address = "", SearchType = SearchType.PeopleSearch, InputType = InputType.Name }), new MvcRouteHandler()) ); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Account", action = "LogOn", id = "" } // Parameter defaults ); The following request works fine: http://localhost:2608/Lookups/PeopleSearch/Name/john/w/smith/seattle/wa/123 main This request does not work: http://localhost:2608/Lookups/PeopleSearch/Name/john//smith//wa/ Not all requests will have all paramters and I would like empty parameters to be passed to the method as empty string or null. Where am I going wrong? The method: public ActionResult Search(string firstname, string middlename, string lastname, string city, string state, string address, SearchType searchtype, InputType inputtype) { SearchRequest r = new SearchRequest { Firstname = firstname, Middlename = middlename, Lastname = lastname, City = city, State = state, Address = address, SearchType = searchtype, InputType = inputtype }; return View(r); }

  • VS2010 Implement Generic Interface expansion doesn't use specified type

    - by TJB
    Using the release version of Visual Studio 2010 I think there's a difference in the "Implement Interface" expansion from VS2008 If I speicify an interface and implement it in a class as so: public interface IRepository<T> where T : IModel { T Get<T>(int id); void Update<T>(); int Add<T>(T item); } public class MockRepository : IRepository<MockUser> { // ... } Then use the "Implement Interface" expansion and get this: public class MockRepository : IRepository<MockUser> { public T Get<T>(int id) { throw new NotImplementedException(); } public void Update<T>() { throw new NotImplementedException(); } public int Add<T>(T item) { throw new NotImplementedException(); } } Instead of what I expected public class MockRepository : IRepository<MockUser> { public MockUser Get<MockUser>(int id) { throw new NotImplementedException(); } public void Update<MockUser>() { throw new NotImplementedException(); } public int Add<MockUser>(MockUser item) { throw new NotImplementedException(); } } The IDE uses the type variable name from the generic interface definition T instead of the specified concrete type MockUser. Is this a bug? Or is something new just for VS2010 / .Net 4.0?

  • SSIS - How do I use a resultset as input in a SQL task and get data types right?

    - by thursdaysgeek
    I am trying to merge records from an Oracle database table to my local SQL table. I have a variable for the package that is an Object, called OWell. I have a data flow task that gets the Oracle data as a SQL statment (select well_id, well_name from OWell order by Well_ID), and then a conversion task to convert well_id from a DT_STR of length 15 to a DT_WSTR; and convert well_name from a DT_STR of length 15 to DT_WSTR of length 50. That is then stored in the recordset OWell. The reason for the conversions is the table that I want to add records to has an identity field: SSIS shows well_id as a DT_WSTR of length 15, well_name a DT_WSTR of length 50. I then have a SQL task that connects to the local database and attempts to add records that are not there yet. I've tried various things: using the OWell as a result set and referring to it in my SQL statement. Currently, I have the ResultSet set to None, and the following SQL statment: Insert into WELL (WELL_ID, WELL_NAME) Select OWELL_ID, OWELL_NAME from OWell where OWELL_ID not in (select WELL.WELL_ID from WELL) For Parameter Mapping, I have Paramater 0, called OWell_ID, from my variable User::OWell. Parameter 1, called OWell_Name is from the same variable. Both are set to VARCHAR, although I've also tried NVARCHAR. I do not have a Result set. I am getting the following error: Error: 0xC002F210 at Insert records to FLEDG, Execute SQL Task: Executing the query "Insert into WELL (WELL_ID, WELL_NAME) Select OWELL..." failed with the following error: "An error occurred while extracting the result into a variable of type (DBTYPE_STR)". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly. I don't think it's a data type issue, but rather that I somehow am not using the resultset properly. How, exactly, am I supposed to refer to that recordset in my SQL task, so that I can use the two recordset fields and add records that are missing?

  • Advice on Method overloads.

    - by Muhammad Kashif Nadeem
    Please see following methods. public static ProductsCollection GetDummyData(int? customerId, int? supplierId) { try { if (customerId != null && customerId > 0) { Filter.Add(Customres.CustomerId == customerId); } if (supplierId != null && supplierId > 0) { Filter.Add(Suppliers.SupplierId == supplierId); } ProductsCollection products = new ProductsCollection(); products.FetchData(Filter); return products; } catch { throw; } } public static ProductsCollection GetDummyData(int? customerId) { return ProductsCollection GetDummyData(customerId, (int?)null); } public static ProductsCollection GetDummyData() { return ProductsCollection GetDummyData((int?)null); } 1- Please advice how can I make overloads for both CustomerId and SupplierId because only one overload can be created with GetDummyData(int? ). Should I add another argument to mention that first argument is CustomerId or SupplierId for example GetDummyData(int?, string). OR should I use enum as 2nd argument and mention that first argument is CustoemId or SupplierId. 2- Is this condition is correct or just checking 0 is sufficient - if (customerId != null && customerId 0) 3- Using Try/catch like this is correct? 4- Passing (int?)null is correct or any other better approach. Edit: I have found some other posts like this and because I have no knowledge of Generics that is why I am facing this problem. Am I right?

  • Multi-dimensional array edge/border conditions

    - by kirbuchi
    Hi, I'm iterating over a 3 dimensional array (which is an image with 3 values for each pixel) to apply a 3x3 filter to each pixel as follows: //For each value on the image for (i=0;i<3*width*height;i++){ //For each filter value for (j=0;j<9;j++){ if (notOutsideEdgesCondition){ *(**(outArray)+i)+= *(**(pixelArray)+i-1+(j%3)) * (*(filter+j)); } } } I'm using pointer arithmetic because if I used array notation I'd have 4 loops and I'm trying to have the least possible number of loops. My problem is my notOutsideEdgesCondition is getting quite out of hands because I have to consider 8 border cases. I have the following handled conditions Left Column: ((i%width)==0) && (j%3==0) Right Column: ((i-1)%width ==0) && (i>1) && (j%3==2) Upper Row: (i<width) && (j<2) Lower Row: (i>(width*height-width)) && (j>5) and still have to consider the 4 corner cases which will have longer expressions. At this point I've stopped and asked myself if this is the best way to go because If I have a 5 line long conditional evaluation it'll not only be truly painful to debug but will slow the inner loop. That's why I come to you to ask if there's a known algorithm to handle this cases or if there's a better approach for my problem. Thanks a lot.

  • C# StackOverflowException

    - by KSwift87
    Problem: I am trying to update a List. If a certain item's ID already exists in the List, I want to add onto that item's quantity. If not, then I want to add another item to the list. cart = (List<OrderItem>)Session["cart"]; for(int counter = cart.Count-1; counter >= 0; counter--) { if (cart[counter].productId == item.productId) { cart[counter].productQuantity += item.productQuantity; } else if (counter == 0) { cart.Add(item); } } "cart[counter]" and "item" represent an instance(s) of a custom object of mine. Currently when I finally find a matching ID, everything APPEARS as though it should work, but I get a StackOverflowException thrown in my custom object class. public int productQuantity { get { return _productQuantity; } set { productQuantity = value; } } It gets thrown right at the open-bracket of the "set". Could somebody please tell me what the heck is wrong because I've been going at this for the past 2+ hours to no avail. Thank you in advance.

  • Help on understanding multiple columns on an index?

    - by Xaisoft
    Assume I have a table called "table" and I have 3 columns, a, b, and c. What does it mean to have a non-clustered index on columns a,b? Is a nonclustered index on columns a,b the same as a nonclustered index on columns b,a? (Note the order). Also, Is a nonclustered index on column a the same as a nonclustered index on a,c? I was looking at the website sqlserver performance and they had these dmv scripts where it would tell you if you had overlapping indexes and I believe it was saying that having an index on a is the same as a,b, so it is redundant. Is this true about indexes? One last question is why is the clustered index put on the primary key. Most of the time the primary key is not queried against, so shouldn't the clustered index be on the most queried column. I am probably missing something here like having it on the primary key speeds up joins? Great explanations. Should I turn this into a wiki and change the title index explanation?

  • Optimizing MySQL for ALTER TABLE of InnoDB

    - by schuilr
    Sometime soon we will need to make schema changes to our production database. We need to minimize downtime for this effort, however, the ALTER TABLE statements are going to run for quite a while. Our largest tables have 150 million records, largest table file is 50G. All tables are InnoDB, and it was set up as one big data file (instead of a file-per-table). We're running MySQL 5.0.46 on an 8 core machine, 16G memory and a RAID10 config. I have some experience with MySQL tuning, but this usually focusses on reads or writes from multiple clients. There is lots of info to be found on the Internet on this subject, however, there seems to be very little information available on best practices for (temporarily) tuning your MySQL server to speed up ALTER TABLE on InnoDB tables, or for INSERT INTO .. SELECT FROM (we will probably use this instead of ALTER TABLE to have some more opportunities to speed things up a bit). The schema changes we are planning to do is adding a integer column to all tables and make it the primary key, instead of the current primary key. We need to keep the 'old' column as well so overwriting the existing values is not an option. What would be the ideal settings to get this task done as quick as possible?

  • Exclude specific value from a Min/Max agregate funcion using ICriteria.

    - by sparks
    I have a schedule (Voyages) table like this: ID Arrival Departure OrderIndex 1 01/01/1753 02/10/2009 0 1 02/11/2009 02/15/2009 1 1 02/16/2009 02/19/2009 2 1 02/21/2009 01/01/1753 3 2 01/01/1753 03/01/2009 0 2 03/04/2009 03/07/2009 1 2 03/09/2009 01/01/1753 2 By design i save '01/01/1753' as a default value if the user doesn't fill a the field on the capture screen and for the very first Arrival and the very last Departure which are never provided. Im using Nhibernate and Criteria, and im wondering whats the best way to query this data if i want to know the First departure and last arrival for each voyage in the table. My first thought was a groupby (ID) and then do some Min and Max with the arrival and departure but the `'01/01/1753' VALUE is messing aronud. ... .SetProjection(Projections.ProjectionList() .Add(Projections.GroupProperty("ID"), "ID") .Add(Projections.Min("DepartureDate"), "DepartureDate") .Add(Projections.Max("ArrivalDate"), "ArrivalDate") ) ... So is there a way to skip this value in the Min function comparison (without losing the whole row of data), or there is a better way to do this, maybe utilizing the OrderIndex that always indicate the correct order of the elements, maybe ordering ASC taking the 1st and then Order DESC and taking the 1 st again, but im not quite sure how to do that with criteria syntax.

  • How to represent and insert into an ordered list in SQL?

    - by Travis
    I want to represent the list "hi", "hello", "goodbye", "good day", "howdy" (with that order), in a SQL table: pk | i | val ------------ 1 | 0 | hi 0 | 2 | hello 2 | 3 | goodbye 3 | 4 | good day 5 | 6 | howdy 'pk' is the primary key column. Disregard its values. 'i' is the "index" that defines that order of the values in the 'val' column. It is only used to establish the order and the values are otherwise unimportant. The problem I'm having is with inserting values into the list while maintaining the order. For example, if I want to insert "hey" and I want it to appear between "hello" and "goodbye", then I have to shift the 'i' values of "goodbye" and "good day" (but preferably not "howdy") to make room for the new entry. So, is there a standard SQL pattern to do the shift operation, but only shift the elements that are necessary? (Note that a simple "UPDATE table SET i=i+1 WHERE i=3" doesn't work, because it violates the uniqueness constraint on 'i', and also it updates the "howdy" row unnecessarily.) Or, is there a better way to represent the ordered list? I suppose you could make 'i' a floating point value and choose values between, but then you have to have a separate rebalancing operation when no such value exists. Or, is there some standard algorithm for generating string values between arbitrary other strings, if I were to make 'i' a varchar? Or should I just represent it as a linked list? I was avoiding that because I'd like to also be able to do a SELECT .. ORDER BY to get all the elements in order.

  • Core Data, Bindings, value transformers : crash when saving

    - by Gael
    Hi, I am trying to store a PNG image in a core data store backed by an sqlite database. Since I intend to use this database on an iPhone I can't store NSImage objects directly. I wanted to use bindings and an NSValueTransformer subclass to handle the transcoding from the NSImage (obtained by an Image well on my GUI) to an NSData containing the PNG binary representation of the image. I wrote the following code for the ValueTransformer : + (Class)transformedValueClass { return [NSImage class]; } + (BOOL)allowsReverseTransformation { return YES; } - (id)transformedValue:(id)value { if (value == nil) return nil; return [[[NSImage alloc] initWithData:value] autorelease]; } - (id)reverseTransformedValue:(id)value { if (value == nil) return nil; if(![value isKindOfClass:[NSImage class]]) { NSLog(@"Type mismatch. Expecting NSImage"); } NSBitmapImageRep *bits = [[value representations] objectAtIndex: 0]; NSData *data = [bits representationUsingType:NSPNGFileType properties:nil]; return data; } The model has a transformable property configured with this NSValueTransformer. In Interface Builder a table column and an image well are both bound to this property and both have the proper value transformer name (an image dropped in the image well shows up in the table column). The transformer is registered and called every time an image is added or a row is reloaded (checked with NSLog() calls). The problem arises when I am trying to save the managed objects. The console output shows the error message : [NSImage length]: unrecognized selector sent to instance 0x1004933a0 It seems like core data is using the value transformer to obtain the NSImage back from the NSData and then tries to save the NSImage instead of the NSData. There are probably workarounds such as the one presented in this post but I would really like to understand why my approach is flawn. Thanks in advance for your ideas and explanations.

  • Hibernate query for multiple items in a collection

    - by aarestad
    I have a data model that looks something like this: public class Item { private List<ItemAttribute> attributes; // other stuff } public class ItemAttribute { private String name; private String value; } (this obviously simplifies away a lot of the extraneous stuff) What I want to do is create a query to ask for all Items with one OR MORE particular attributes, ideally joined with arbitrary ANDs and ORs. Right now I'm keeping it simple and just trying to implement the AND case. In pseudo-SQL (or pseudo-HQL if you would), it would be something like: select all items where attributes contains(ItemAttribute(name="foo1", value="bar1")) AND attributes contains(ItemAttribute(name="foo2", value="bar2")) The examples in the Hibernate docs didn't seem to address this particular use case, but it seems like a fairly common one. The disjunction case would also be useful, especially so I could specify a list of possible values, i.e. where attributes contains(ItemAttribute(name="foo", value="bar1")) OR attributes contains(ItemAttribute(name="foo", value="bar2")) -- etc. Here's an example that works OK for a single attribute: return getSession().createCriteria(Item.class) .createAlias("itemAttributes", "ia") .add(Restrictions.conjunction() .add(Restrictions.eq("ia.name", "foo")) .add(Restrictions.eq("ia.attributeValue", "bar"))) .list(); Learning how to do this would go a long ways towards expanding my understanding of Hibernate's potential. :)

I have successfully hooked myself up to the SubreportProcessing event, I can find the correct sub-report through e.ReportPath, and I can add datasources through e.DataSources.Add. But I find no way of adding report parameters?? I have found people suggesting to add them to the master report, but I don't really want to do that, since the master report shouldn't have to be connected to the sub-report at all, other than that it is wrapping the sub-report. I am using one report as a master template, printing name of the report, page numbers etc. And the subreport is going to be the report itself. And if I could only find a way to set those report parameters of the sub-report I would be good to go... Clarification: Creating/Defining the parameters is not the problem. The problem is to set their values. I thought the natural thing to do was to do it in the SubreportProcessing event. And the SubreportProcessingEventArgs do in fact have a Parameters property. But it is read only! So how do you use that? How can I set their value?

  • Referencing object's identity before submitting changes in LINQ

    - by Axarydax
    Hi, is there a way of knowing ID of identity column of record inserted via InsertOnSubmit beforehand, e.g. before calling datasource's SubmitChanges? Imagine I'm populating some kind of hierarchy in the database, but I wouldn't want to submit changes on each recursive call of each child node (e.g. if I had Directories table and Files table and am recreating my filesystem structure in the database). I'd like to do it that way, so I create a Directory object, set its name and attributes, then InsertOnSubmit it into DataContext.Directories collection, then reference Directory.ID in its child Files. Currently I need to call InsertOnSubmit to insert the 'directory' into the database and the database mapping fills its ID column. But this creates a lot of transactions and accesses to database and I imagine that if I did this inserting in a batch, the performance would be better. What I'd like to do is to somehow use Directory.ID before commiting changes, create all my File and Directory objects in advance and then do a big submit that puts all stuff into database. I'm also open to solving this problem via a stored procedure, I assume the performance would be even better if all operations would be done directly in the database.

  • Is the order of params important in NHibernate?

    - by Blake Blackwell
    If I have an int parameter followed by a string parameter in a sproc I get the following error: Input string was not in the correct format However, if I switch those parameters in the sproc than I get the result set I expect. Are params sorted by data type, or do I have to do anything special in my config file? I've included my code for reference: Config File <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="NHibernateDemo" namespace="NHibernateDemo.Domain"> <class name="Blake_Test" table="Blake_Test"> <id name="TestId" column="TESTID"></id> <property name="TestName" column="TESTNAME" /> <loader query-ref="GetBlakeTest"/> </class> <sql-query name="GetBlakeTest" callable="true"> <return class="Blake_Test" /> call procedure AREA51.NHIBERNATE_TEST.GetBlakeTest(:int_TestId, :vch_TestName) </sql-query> </hibernate-mapping> Sproc Code: PROCEDURE GetBlakeTest ( ret_cursor OUT SYS_REFCURSOR, int_testid integer, vch_testname varchar2 ) AS BEGIN OPEN ret_cursor FOR SELECT TestId, TestName FROM blake_test WHERE testid = int_testid ORDER BY TestName DESC; END GetBlakeTest; END NHIBERNATE_TEST; Executing Code: IQuery query1 = session.GetNamedQuery( "GetBlakeTest" ); query1.SetParameter( "int_TestId", 1 ); query1.SetParameter( "vch_TestName", "TEST" ); IList<Blake_Test> mystuff = query1.List<Blake_Test>();

  • Executing javascript script after ajax-loaded a page - doesn't work

    - by Deukalion
    I'm trying to get a page with AJAX, but when I get that page and it includes Javascript code - it doesn't execute it. Why? Simple code in my ajax page: <script type="text/javascript"> alert("Hello"); </script> ...and it doesn't execute it. I'm trying to use Google Maps API and add markers with AJAX, so whenever I add one I execute a AJAX page that gets the new marker, stores it in a database and should add the marker "dynamically" to the map. But since I can't execute a single javascript function this way, what do I do? Is my functions that I've defined on the page beforehand protected or private? ** UPDATED WITH AJAX FUNCTION ** function ajaxExecute(id, link, query) { if (query != null) { query = query.replace("amp;", ""); } if (window.XMLHttpRequest) { // code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else { // code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { if (id != null) { document.getElementById(id).innerHTML=xmlhttp.responseText; } } } if (query == null) { xmlhttp.open("GET",link,true); } else { if (query.substr(0, 1) != "?") { xmlhttp.open("GET",link+"?"+query,true); } else { xmlhttp.open("GET",link+query,true); } } xmlhttp.send(); }
