• Issues with Ext-JS 1.1 date fields and Firefox 3.x / IE 8

  - by Cruachan

  I'm modifying an older website for a client that uses Ext-JS 1.1 and I'm having issues with display of date fields in IE and particularly Firefox. The site was left in a semi-implemented state previously, so there's not been a perceived problem before. In Chrome and Safari everything looks fine and the datepicker drops down and displays correctly. However in Firefox the picker is displayed widened to cover the maximum scrollable brower width (very wide indeed), and in IE it's truncated to about two thirds of the width it should be. I am somewhat uncertain that this is due to our css, but because Chrome and Safari work fine I think it might be a problem with Ext-js itself. I realise that this is an old version of Ext-JS, but because everything else works fine I don't want to go to the trouble of upgrading unless that would be very straightforward (but how difficult would that be?) I don't myself use ExtJS and this is the only website my client has with it - so I'm really looking for the simplest possible solution.

• Display/Edit fields across tables in a Django Form

  - by jamida

  I have 2 tables/models, which for all practical purposes are the same as the standard Author/Book example, but with the additional restriction that in my application each Author can only write 0 or 1 books. (eg, the ForeignKey field in the Book model is or can be a OneToOneField, and there may be authors who have no corresponding book in the Book table.) I would like to be able to display a form showing multiple books and also show some fields from the corresponding Author table (eg author_name, author_address). I followed the example of the inlineformset and but that doesn't even display the author name in the generated form.

• What is a header? Especially, what are POST@GET headers?

  - by brilliant

  Hello, I've been trying to find a Python code that would log in to my Yahoo account from "Google App Engine". One supporter on "StackOverflow" gave me this three-step plan: Simulate normal login and save login page that you get; Save POST&GET headers with "Wireshark"; Compare login page with those headers and see what fields you need to include with your request; The problem here is that I have never used "Wireshark" before. Plus, I don't know what the POST&GET headers are. Can You, please, explain it to me (preferably with some example). Thank You.

• Server removes all custom HTTP header fields

  - by MartinMoizard

  Hello, I've been trying to receive HTTP requests with custom fields in the headers but it seems like my server removes them... I printed the headers of the request when I arrive on my page.php. I see that : body uri http://url.com/oauth.php/request_token parameters headers Array ....*/* ....gzip, deflate ....en-us ....keep-alive ....s320650601.onlinehome.fr ....DearStranger/1.0 CFNetwork/485.12.7 Darwin/10.6.0 method POST when I should be seeing that (it is working on a local version) body uri http://localhost:8888/oauth.php/request_token parameters headers Array ....*/* ....gzip, deflate ....en-us ....OAuth realm="", oauth_consumer_key="582d95bd45d455fa2e5819f88fc0c5a104d2c7ff3", oauth_signature_method="HMAC-SHA1", oauth_signature="7mKKzEw0Clv237nBHFzcTcA3SCE%3D", oauth_timestamp="1295267612", oauth_nonce="C546644E-8918-4FA3-A2A0-DAADCF7D1E5A", oauth_version="1.0" ....keep-alive ....0 ....localhost:8888 ....DearStranger/1.0 CFNetwork/485.12.7 Darwin/10.6.0 method POST I am using php 5.2.17 on the server.

• How to dynamically choose two fields from a Linq query as a result

  - by Dr. Zim

  If you have a simple Linq query like: var result = from record in db.Customer select new { Text = record.Name, Value = record.ID.ToString() }; which is returning an object that can be mapped to a Drop Down List, is it possible to dynamically specify which fields map to Text and Value? Of course, you could do a big case (switch) statement, then code each Linq query separately but this isn't very elegant. What would be nice would be something like: (pseudo code) var myTextField = db.Customer["Name"]; // Could be an enumeration?? var myValueField = db.Customer["ID"]; // Idea: choose the field outside the query var result = from record in db.Customer select new { Text = myTextField, Value = myValueField };

• Custom Sorting on Custom Field in Django

  - by RotaJota

  In my app, I have defined a custom field to represent a physical quantity using the quantities package. class AmountField(models.CharField): def __init__(self, *args, **kwargs): ... def to_python(self, value): create_quantities_value(value) Essentially the way it works is it extends CharField to store the value as a string in the database "12 min" and represents it as a quantities object when using the field in a model array(12) * min Then in a model it is used as such: class MyModel(models.Model): group = models.CharField() amount = AmountField() class Meta: ordering = ['group', 'amount'] My issue is that these fields do not seem to sort by the quantity, but instead by the string. So if I have some objects that contain something like {"group":"A", "amount":"12 min"} {"group":"A", "amount":"20 min"} {"group":"A", "amount":"2 min"} {"group":"B", "amount":"20 min"} {"group":"B", "amount":"1 hr"} they end up sorted something like this: >>> MyModel.objects.all() [{A, 12 min}, {A, 2 min}, {A, 20 min}, {B, 1 hr}, {B, 20 min}] essentially alphabetical order. Can I give my custom AmountField a comparison function so that it will compare by the python value instead of the DB value?

• Tuple struct constructor complains about private fields

  - by Grubermensch

  I am working on a basic shell interpreter to familiarize myself with Rust. While working on the table for storing suspended jobs in the shell, I have gotten stuck at the following compiler error message: tsh.rs:8:18: 8:31 error: cannot invoke tuple struct constructor with private fields tsh.rs:8 let mut jobs = job::JobsList(vec![]); ^~~~~~~~~~~~~ It's unclear to me what is being seen as private here. As you can see below, both of the structs are tagged with pub in my module file. So, what's the secret sauce? tsh.rs use std::io; mod job; fn main() { // Initialize jobs list let mut jobs = job::JobsList(vec![]); loop { /*** Shell runtime loop ***/ } } job.rs use std::fmt; pub struct Job { jid: int, pid: int, cmd: String } impl fmt::Show for Job { /*** Formatter ***/ } pub struct JobsList(Vec<Job>); impl fmt::Show for JobsList { /*** Formatter ***/ }

• javascript/jquery input fields cleanup

  - by user271619

  I've created a few input fields, that I am cleaning up as the user types. So, I'm using a keystroke detection event, like .keyup() It's all working very well, but I do notice one thing that's rather annoying for the users. While the script is cleaning the data as they type, their cursor is being sent to the end of the input field. So, if you want to edit the middle of the value, you're cursor immediately goes to the end of the box. Does anyone know of a way to maintain the cursor's current position inside the input field? I'm not holding my breath, but I thought I'd ask. Here's the cleanup code I'm using: $(".pricing").keyup(function(){ // clean up anything non-numeric **var itemprice = $("#itemprice").val().replace(/[^0-9\.]+/g, '');** // return the cleaner value back to the input field **$("#itemprice").val(itemprice);** });

• String Field Sizes for unicode database fields using different data access components

  - by Serg

  mjustin in his question 1 and question 2 says that TWideStringField.Size property for UTF8 fields in Delphi 2009 dbExpress is 4 times larger than the logical field size (max number of characters in the field). I inclined to consider this a dbExpress bug. That is what Delphi 2009 Help says: The interpretation of Size depends on the data type. The meaning of Size for data types that use it is given in the following table. For all other data types, Size is not used and its value is always 0. ftString - Size is the maximum number of characters in the string. I am using FibPlus 6.9.9 and it follows the above documentation - the string field size is the maximum number of characters, not bytes. So the question also implies the following question: Are DbExpress drivers in Delphi 2009 unusable for unicode databases?

• Change field access to getter / setter method access

  - by Chris Dennett

  Hi everyone, is it possible to change external class field accesses in Java to getter / setter calls automatically, and also hide the exposed fields? I'm using Javabeans and I want change notifications when a field property changes (this is important). I've found cglib which can automatically insert the property change call to the PropertyChangeSupport field. I'd like this question to be a discussion of the issues posed and their solutions. I know about Project Lombok, but this appears to modify the source code, and additionally doesn't support field access modification. Perhaps with modifications to Lombok, this could be supported, or are there other solutions? Cheers and thanks in advance, Chris

• Search over multiple fields

  - by schneck

  Hi there, I think I don't unterstand django-haystack properly: I have a data model containing several fields, and I would to have two of them searched: class UserProfile(models.Model): user = models.ForeignKey(User, unique=True, default=None) twitter_account = models.CharField(max_length=50, blank=False) My search index settings: class UserProfileIndex(SearchIndex): text = CharField(document=True, model_attr='user') twitter_account = CharField(model_attr='twitter_account') def get_queryset(self): """Used when the entire index for model is updated.""" return UserProfile.objects.all() But when I perform a search, only the field "username" is searched; "twitter_account" is ignored. When I select the Searchresults via dbshell, the objects contain the correct values for "user" and "twitter_account", but the result page shows a "no results": {% if query %} <h3>Results</h3> {% for result in page.object_list %} <p> <a href="{{ result.object.get_absolute_url }}">{{ result.object.id }}</a> </p> {% empty %} <p>No results</p> {% endfor %} {% endif %} Any ideas?

  Hey Guys Ive used the ObjectBindingDatasource to bind to a class Ive called "ReportViewModel" which contains properties such as List Companies {get; set;} List Managers {get; set;} in its constructor Im just calling a method to populate with dummy data Managers = new ReportDataRepository().GetManagers(); Companies = new ReportDataReposiroty().GetCompanies(); ... When i create the new Datasource , it shows the ReportViewModel class with the Lists under it. I expand the Companies object and attempt draging and dropping fields onto the report designer and it works. Though doesnt allow me to drag and drop for any other List. Any guidance would be really appreciated.

• java serialization and final fields

  - by mdma

  I have an class defining an immutable value type that I now need to serialize. The immutability comes from the final fields which are set in the constructor. I've tried serializing, and it works (surprisingly?) - but I've no idea how. Here's an example of the class public class MyValueType implements Serializable { private final int value; private transient int derivedValue; public MyValueType(int value) { this.value = value; this.derivedValue = derivedValue(value); } // getters etc... } Given that the class doesn't have a no arg constructor, how can it be instantiated and the final field set? (An aside - I noticed this class particularly because IDEA wasn't generating a "no serialVersionUID" inspection warning for this class, yet successfully generated warnings for other classes that I've just made serializable.)

• Drupal: Content in blocks from node_reference fields?

  - by Marco

  After only a few weeks of working with Drupal I've come up with a recurring problem, which I don't really have an optimal solution to, so I'm hoping that someone here might be able to give some best practice pointers. What I have is a region inside my node.tpl.php, which is populated with blocks that display content from two different CCK fields of the type node_reference. This works fine when displaying a single node. The problem appears when I need to use a view. For example, lets say I have a news listing, and a single news item view. When I display the single news item I can use the news node node_reference field to reference whatever material I would like to have in my sidebar, but when on the news listing view I would like to reference nodes separately. What would be the best practice to solve this? I'm having a few ideas, but none seem like the logical choice, how would you do?

• Drupal Views pulling Data Fields

  - by askon

  I'm a little new to drupal but have been using things like devel module and theme developer to speed up the learning process. My question, is it possible to theme an entire views BLOCK from a single views tpl.php page OR even a preprocess? When I'm grabbing the $view object I can see results $node-result, it has all of the results, but it doesn't have all my views fields. I'm missing things like, node path, taxonomy titles and paths, etc. From my understanding, Drupal wants you to individually theme EACH output field. It seems rather superfluous to create so many extra templates when I've already got over HALF of my results coming through the $view object Would outputting node over field make this easier? Or am going in the wrong direction with $view-result? Thanks!

• Read only particular fields from CSV File in vb.net

  - by fireBand

  Hi, I have this code to read a CVS file. It reads each line, devides each line by delimiter ',' and stored the field values in array 'strline()' . How do I extract only required fields from the CSV file? For example if I have a CSV File like Type,Group,No,Sequence No,Row No,Date (newline) 0,Admin,3,345678,1,26052010 (newline) 1,Staff,5,78654,3,26052010 I Need only the value of columns Group,Sequence No and date. Thanks in advance for any ideas. Dim myStream As StreamReader = Nothing ' Hold the Parsed Data Dim strlines() As String Dim strline() As String Try myStream = File.OpenText(OpenFile.FileName) If (myStream IsNot Nothing) Then ' Hold the amount of lines already read in a 'counter-variable' Dim placeholder As Integer = 0 strlines = myStream.ReadToEnd().Split(Environment.NewLine) Do While strlines.Length <> -1 ' Is -1 when no data exists on the next line of the CSV file strline = strlines(placeholder).Split(",") placeholder += 1 Loop End If Catch ex As Exception LogErrorException(ex) Finally If (myStream IsNot Nothing) Then myStream.Close() End If End Try

• Drupal 6: Taxonomy splot up in managed fields?

  - by Ardi Coetzee

  So you have two taxonomies, namely: "Business Type" and "Location" This is assigned to a node called BUSINESS. In effect, when the user creates a BUSINESS node, her has to choose for example, location "New York" and type "Information Services". My problem is when: a) Capturing the taxonomy, and b) Displaying the taxonomy I want the two terms to be separated from each other. I.e. I want to be able to move the two terms individual positions in the MANAGE FIELDS view, so that they can be grouped or placed seperately. Currently, Drupal only allows one entry, called "TAXONOMY" which is effectively the two terms next to each other. This is what I have: This is what I want: Bare in mind, I need to be able to use this with Hierarchical Select, which means Content Taxonomy is not an option.

• Querying and ordering results of a database in grails using transient fields

  - by Azder

  I'm trying to display paged data out of a grails domain object. For example: I have a domain object Employee with the properties firstName and lastName which are transient, and when invoking their setter/getter methods they encrypt/decrypt the data. The data is saved in the database in encrypted binary format, thus not sortable by those fields. And yet again, not sortable by transient ones either, as noted in: http://www.grails.org/GSP+Tag+-+sortableColumn . So now I'm trying to find a way to use the transients in a way similar to: Employee.withCriteria( max: 10, offset: 30 ){ order 'lastName', 'asc' order 'firstName', 'asc' } The class is: class Employee { byte[] encryptedFirstName byte[] encryptedLastName static transients = [ 'firstName', 'lastName' ] String getFirstName(){ decrypt("encryptedFirstName") } void setFirstName(String item){ encrypt("encryptedFirstName",item) } String getLastName(){ decrypt("encryptedLastName") } void setLastName(String item){ encrypt("encryptedLastName",item) } }

• MySQL: Storage of multiple text fields for a record

  - by Tom

  An inexperienced question: I need to store about 10 unknown-length text fields per record into a MySQL table. I expect no more than 50K rows in total for this table but speed is important. The database actions will be solely SELECTs for all practical purposes. I'm using InnoDB. In other words: id | text1 | text2 | text3 | .... | text10 As I understand that MySQL will store the text elsewhere and use its own indicators on the table itself, I'm wondering whether there's any fundamental performance implications that I should be worrying about given the way the data is stored? (i.e. several "sub-fetches" from the table). Thank you.

• Put logic behind generated LinqToSql fields

  - by boris callens

  In a database I use throughout several projects, there is a field that should actually be a boolean but is for reasons nobody can explain to me a field duplicated over two tables where one time it is a char ('Y'/'N') and one time an int (1/0). When I generate a datacontext with LinqToSql the fields off course gets these datatypes. It would be nice if I don't have to drag this stupid choice of datatype throughout the rest of my application. Is there a way to give the generated classes a little bit of logic that just return me return this.equals('Y'); and return this==1; Preferably without having to make an EXTRA field in my partial class. It would be a solution to give the generated field a totally different name that can only be accessed through the partial class and then generate the extra field with the original name with my custom logic in the partial class. I don't know how to alter the accesibility level in my generated class though.. Any suggestions?

• Database Modelling - Conceptually different entities but with near identical fields

  - by Andrew Shepherd

  Suppose you have two sets of conceptual entities: MarketPriceDataSet which has multiple ForwardPriceEntries PoolPriceForecastDataSet which has multiple PoolPriceForecastEntry Both different child objects have near identical fields: ForwardPriceEntry has MarketPriceDataSetId (foreign key to parent table) StartDate EndDate SimulationItemId ForwardPrice PoolPriceForecastEntry has PoolPriceForecastDataSetId (foreign key to parent table) StartDate EndDate SimulationItemId ForecastPoolPrice If I modelled them as separate tables, the only difference would be the foreign key, and the name of the price field. There has been a debate as to whether the two near identical tables should be merged into one. Options I've thought of to model this is: Just keep them as two independent, separate tables Have both sets in the one table with an additional "type" field, and a parent_id equalling a foreign key to either parent table. This would sacrifice referential integrity checks. Have both sets in the one table with an additional "type" field, and create a complicated sequence of joining tables to maintain referential integrity. What do you think I should do, and why?

• How to access fields in JSON object by index

  - by Stefan

  I know this isn't the best way to do it, but I have no other choice :( I have to access the items in JSONObject by their index. The standard way to access objects is to just wirte this[objectName] or this.objectName. I also found a method to get all the fields inside a json object: (for (var key in p) { if (p.hasOwnProperty(key)) { alert(key + " -> " + p[key]); } } (Soruce : Loop through Json object). However there is no way of accessing the JSONfields directly by a index. The only way I see right now, is to create an array, with the function above, get the fieldname by index and then get the value by fieldname. As far as I see it, the p (in our case the JSON file must be an iteratable array to, or else the foreach loop wouldn't work. How can I access this array directly? Or is it some kind of unsorted list?

  What is the best approach to display the summery of DETAILED.Fields in its master table? E.g. I have a master table called 'BILL' with all the bill related data and a detailed table ('BILL_DETAIL') with the bill detailed related data, like NAME, PRICE, TAX, ... Now I want to list all BILLS, without the details, but with the sum of the PRICE and TAX stored in the detail table. Here is a simplified schema of that tables: TABLE BILL ---------- - ID - NAME - ADDRESS - ... TABLE BILL_DETAIL ----------------- - ID - BILLID - PORDUCT_NAME - PRICE - TAX - ... The retrieved table row should look like this: BILL.CUSTOMER_NAME, BILL.CUSTOMER_ADDRESS, sum(BILL_DETAIL.PRICE), sum(BILL.DETAIL.TAX), ... Any sugguestions?
