  • Validating only selected fields using ASP.NET MVC 2 and Data Annotations

    - by thinknow
    I'm using Data Annotations with ASP.NET MVC 2 as demonstrated in this post: http://weblogs.asp.net/scottgu/archive/2010/01/15/asp-net-mvc-2-model-validation.aspx Everything works fine when creating / updating an entity where all required property values are specified in the form and valid. However, what if I only want to update some of the fields? For example, let's say I have an Account entity with 20 fields, but I only want to update Username and Password? ModelState.IsValid validates against all the properties, regardless of whether they are referenced in the submitted form. How can I get it to validate only the fields that are referenced in the form?

  • Strong name validation failed on VB.NET Assembly

    - by Matt Baker
    I have a VB.Net 1.1 application works just fine after compiling in Visual Studio. However, I want to use ILMerge to combine all the referenced assemblies into a single executable just to make it easier to move around. After I send it through ILMerge and try to run it I get the error "Strong name validation failed for .exe" ..... But none of my stuff is strong named! I saw this post here: http://stackoverflow.com/questions/403731/strong-name-validation-failed and tried running it through 'sn.exe -Vr .exe' but that gives me this error: ".exe does not represent a strongly named assembly" Has anyone else had this problem before? How do I fix it?

  • Test-Driven Development Problem

    - by Zeck
    Hi guys, I'm newbie to Java EE 6 and i'm trying to develop very simple JAX-RS application. RESTfull web service working fine. However when I ran my test application, I got the following. What have I done wrong? Or am i forget any configuration? Of course i'm create a JNDI and i'm using Netbeans 6.8 IDE. In finally, thank you for any advise.

  • Linq to sql add/update in different methods with different datacontexts

    - by Kurresmack
    I have to methods, Add() and Update() which both create a datacontext and returns the object created/updated. In my unit test I call first Add(), do some stuff and then call Update(). The problem is that Update() fails with the exception: System.Data.Linq.DuplicateKeyException: Cannot add an entity with a key that is already in use.. I understand the issue but want to know what to do about it? I've read a bit about how to handle multiple datacontext objects and from what I've heard this way is OK. I understand that the entity is still attached to the datacontext in Add() but I need to find out how to solve this? Thanks in advance

  • How can I disable multiple links with jQuery?

    - by Samantha J
    I have the following HTML: <a title="Login" data-href="/MyAccount/Access/Login" data-title="Admin" data-entity="n/a" id="loginLink" class="nav-button dialogLink"><b>Login</b></a> <a title="Register" data-href="/MyAccount/Access/Register" data-title="Admin" data-entity="n/a" id="registerLink" class="nav-button dialogLink"><b>Register</b></a> When a user clicks on the #loginLink or #registerLink I would like to disable the link and call a dialog script. I created the following function: $("#loginLink, #registerLink") .click(function () { $('#loginLink').prop('disabled', true); $('#registerLink').prop('disabled', true); dialog(this); }); It calls the dialog correctly but doesn't disable the links and if I click the buttons more than once it calls up more than one dialog box. Is there something I am doing wrong? I can't see why it would not work.

  • Winform BindingSources - Question

    - by Stephen Patten
    I have a windows form (net 2.0) with controls on it bound to an entity (w/ INotifyPropertyChanged) through a BindingSource..works. On the same form I have a drop down list that is also wired up through a BindingSource..works Here's a sample of the relevant code: m_PlanItemLookupBindingSource.DataSource = GetBusinessLogic().RetrievePaymentPlanLookups(); // Collection of PaymentPlans paymentPlanType.Properties.DataSource = m_PlanItemLookupBindingSource; paymentPlanType.Properties.DisplayMember = "Name"; paymentPlanType.Properties.ValueMember = "ID"; paymentPlanType.DataBindings.Add(new Binding("EditValue", m_PlanBindingSource, "PaymentPlanID", true, DataSourceUpdateMode.OnPropertyChanged, null, "D")); agencyComission.DataBindings.Add(new Binding("EditValue", m_PlanBindingSource, "AgencyCommission", true, DataSourceUpdateMode.OnPropertyChanged, null, "P1")); billingType.DataBindings.Add(new Binding("Text", m_PlanBindingSource, "BillingType")); So when I change a value in the drop down list I thought that the m_PlanItemLookupBindingSource Current property would change along with the PaymentPlanID property of the entity which does change. Just a bit confused. Thanks in advance, Stephen

  • Unit Testing Hibernate's Optimistic Locking (within Spring)

    - by Michal Bachman
    I'd like to write a unit test to verify that optimistic locking is properly set up (using Spring and Hibernate). I'd like to have the test class extend Spring's AbstractTransactionalJUnit4SpringContextTests. What I want to end up with is a method like this: @Test (expected = StaleObjectStateException.class) public void testOptimisticLocking() { A a = getCurrentSession().load(A.class, 1); a.setVersion(a.getVersion()-1); getCurrentSession().saveOrUpdate(a); getCurrentSession().flush(); fail("Optimistic locking does not work"); } This test fails. What do you recommend as a best practice? The reason I am trying to do this is that I want to transfer the version to the client (using a DTO). I want to prove that when the DTO is sent back to the server and merged with a freshly loaded entity, saving that entity will fail if it's been updated by somebody else in the meantime.

  • BigDecimal precision not persisted with javax.persistence annotations

    - by dkaczynski
    I am using the javax.persistence API and Hibernate to create annotations and persist entities and their attributes in an Oracle 11g Express database. I have the following attribute in an entity: @Column(precision = 12, scale = 9) private BigDecimal weightedScore; The goal is to persist a decimal value with a maximum of 12 digits and a maximum of 9 of those digits to the right of the decimal place. After calculating the weightedScore, the result is 0.1234, but once I commit the entity with the Oracle database, the value displays as 0.12. I can see this by either by using an EntityManager object to query the entry or by viewing it directly in the Oracle Application Express (Apex) interface in a web browser. How should I annotate my BigDecimal attribute so that the precision is persisted correctly? Note: We use an in-memory HSQL database to run our unit tests, and it does not experience the issue with the lack of precision, with or without the @Column annotation.

  • mvc2 validation problem (ambiguous reference between model and models)

    - by ile
    I followed instructions for mvc validation but I can't manage to solve this problem.... This is linq to sql model: I set Entity namespace to be CMS.Model If I try to declare partial class Article in Portal.Models namespace: public partial class Article { .... } Then, after using Article article somewhere in code I get following error: 'Article' is an ambiguous reference between 'Portal.Models.Article' and 'CMS.Model.Article' Portal is project name and CMS is area.... I followed these instructions I aslo created NerdDinner from scratch and in that example validation works. I can't figure out what am I doing wrong... someone noticed my mistake? Is it related with giving name to Entity namespace (in tutorial they used default one) Thanks in advance! PS I'd like to note that I'm c# newbie so I'm not really familiar with these partial classes

  • Get children count via HQL

    - by Thomas Lötzer
    Hi, I have a one-to-many mapping between a parent entity and child entities. Now I need to find the number of children associated with each parent for a list of parents. I am trying to do this with HQL but I am not sure how I can get the list of parents in there. Also, I don't know how I can return the entity itself and not just its ID. My current HQL query is: select new map(parent.id as parentId, count(*) as childCount) from Parent parent left join parent.children children group by parent.id but this only returns the ID and does not filter on specific parents. EDIT Based on Pascal's answer I have modified the query to select new map(parent as parent, count(elements(parent.children)) as childCount) from Parent parent group by parent That does work, but is prohibitively slow: 30 seconds instead of 400 ms on the same database.

  • How to retrieve combobox selection in a windows form

    - by Edward Leno
    All, I have a simple windows form with a combobox and a 'OK' button. After clicking the 'OK' button, I want to retrieve the selected combobox value. The GetUserForm has 2 controls: combobox named cmbUser, with a list of 2 values button named btnOK Nothing has been done to the GetUserForm class itself. The class contains: public partial class GetUserForm : Form { public STAMP_GetUser() { InitializeComponent(); } } GetUserForm f = new GetUserForm(); f.ShowDialog(); // not sure how to access the combobox selected value? Do I need to initialize something in the class? Or can I access the controls on the form using the 'f' variable above?

  • Inheriting from class that inherits from DynamicObject

    - by SeveQ
    Hello there, I'm experimenting with C# 4.0's dynamic object model. I've created an abstract class named "Block" that inherits from DynamicObject. It overrides TryGetMember and TrySetMember. Furthermore I've created a usable class named "Brush" that inherits from "Block". I want it to be usable dynamically. But when I create a dynamic object from it and try to access a runtime bound member, it pelts me with an exception telling me that the member doesn't exist. The overridden TryGetMember or TrySetMember methods of the abstract parent class aren't getting called. Is this behaviour to be expected? Thank you!

  • Hibernate + Spring : cascade deletion ignoring non-nullable constraints

    - by E.Benoît
    Hello, I seem to be having one weird problem with some Hibernate data classes. In a very specific case, deleting an object should fail due to existing, non-nullable relations - however it does not. The strangest part is that a few other classes related to the same definition behave appropriately. I'm using HSQLDB 1.8.0.10, Hibernate 3.5.0 (final) and Spring 3.0.2. The Hibernate properties are set so that batch updates are disabled. The class whose instances are being deleted is: @Entity( name = "users.Credentials" ) @Table( name = "credentials" , schema = "users" ) public class Credentials extends ModelBase { private static final long serialVersionUID = 1L; /* Some basic fields here */ /** Administrator credentials, if any */ @OneToOne( mappedBy = "credentials" , fetch = FetchType.LAZY ) public AdminCredentials adminCredentials; /** Active account data */ @OneToOne( mappedBy = "credentials" , fetch = FetchType.LAZY ) public Account activeAccount; /* Some more reverse relations here */ } (ModelBase is a class that simply declares a Long field named "id" as being automatically generated) The Account class, which is one for which constraints work, looks like this: @Entity( name = "users.Account" ) @Table( name = "accounts" , schema = "users" ) public class Account extends ModelBase { private static final long serialVersionUID = 1L; /** Credentials the account is linked to */ @OneToOne( optional = false ) @JoinColumn( name = "credentials_id" , referencedColumnName = "id" , nullable = false , updatable = false ) public Credentials credentials; /* Some more fields here */ } And here is the AdminCredentials class, for which the constraints are ignored. @Entity( name = "admin.Credentials" ) @Table( name = "admin_credentials" , schema = "admin" ) public class AdminCredentials extends ModelBase { private static final long serialVersionUID = 1L; /** Credentials linked with an administrative account */ @OneToOne( optional = false ) @JoinColumn( name = "credentials_id" , referencedColumnName = "id" , nullable = false , updatable = false ) public Credentials credentials; /* Some more fields here */ } The code that attempts to delete the Credentials instances is: try { if ( account.validationKey != null ) { this.hTemplate.delete( account.validationKey ); } this.hTemplate.delete( account.languageSetting ); this.hTemplate.delete( account ); } catch ( DataIntegrityViolationException e ) { return false; } Where hTemplate is a HibernateTemplate instance provided by Spring, its flush mode having been set to EAGER. In the conditions shown above, the deletion will fail if there is an Account instance that refers to the Credentials instance being deleted, which is the expected behaviour. However, an AdminCredentials instance will be ignored, the deletion will succeed, leaving an invalid AdminCredentials instance behind (trying to refresh that instance causes an error because the Credentials instance no longer exists). I have tried moving the AdminCredentials table from the admin DB schema to the users DB schema. Strangely enough, a deletion-related error is then triggered, but not in the deletion code - it is triggered at the next query involving the table, seemingly ignoring the flush mode setting. I've been trying to understand this for hours and I must admit I'm just as clueless now as I was then.

  • How do you get the glyph for a character encoded as '&#333;' from a utf-8 encoded database field usi

    - by AE
    I have a MySQL database table with a collation of 'utf8_general_ci' and the value in the field is: x & #299; bán yá wén (without the spaces). When this is converted (for example by StackOverflow's editor) it looks like this: xī bán yá wén where the second character looks like a lower case i with a bar over the top. In PHP, what function converts the & #299 ; entity into the ī character? I've tried using html_entity_decode($str,ENT_COMPAT,'UTF-8'), however I get characters like the following: yÄ«n wén or zhÅ•ng wén I'm pretty sure there's something I don't understand about the decoding, which is why I'm using the wrong function. Can anyone shed some light on how to get the single character glyph that's represented by the entity & #299 and similar high-number characters above 255? Many thanks, AE

  • EJB 3 Session Bean Design for Simple CRUD

    - by sdoca
    I am writing an application that's sole purpose in life is to do CRUD operations for maintaining records in database. There are relationships between some of the tables/entities. Most examples I've seen for creating session beans deals with complex business logic/operations that interact with many entities which I don't have. Since my application is so very basic, what would be the best design for the session bean(s)? I was thinking of having one session bean per entity which had CRUD the methods defined. Then I thought of combining all of those session beans into a single session bean. And then I found this blog entry which is intriguing, but I must admit I don't understand all of it (what is a ServiceFacade?). I'm leaning towards session bean/entity class, but would like to hear more experienced opinions. Thanks.

  • Can't set default value of string property to "" in the Xcode CoreData model designer

    - by glenc
    I have an entity in my datamodel with a string property that is currently optional, and I'd like to convert this property to a required property with a default value of the empty string. As others have discovered, leaving the default value blank results in validation errors (since the designer interprets this as NULL), but trying '', "", or @"" as the default value results in those literal characters being interpreted as the default, rather than the empty zero-length string, as desired. I did find this thread on Google, however, apart from the solution being really ugly (model definition split between the .xcdatamodel and objc source), it also doesn't work for lightweight migrations because those migrations are done solely based on the .xcdatamodel files and the objc logic from your entity implementations isn't loaded. Is there any way to achieve this in the data model designer?

    When getting the nodeValue of a DOMNode object that has entities in the nodeValue (i.e. a & gt;) then it converts the entity into it's printable character (i.e. ) Does anyone know of a way to get it to keep it as an entity, it really messes up string comparisons when it converts to something unexpected. The following code reproduces the problem you will notice the length of the dump is 3 when it should be 6. <?php $xml='<?xml version="1.0"?> <root> <element>&gt;</element> </root>'; $a=new DOMDocument(); $a->loadXML($xml); var_dump($a->childNodes->item(0)->nodeValue);

  • How to find NSOutlineView row index when using NSTreeController

    - by velocityb0y
    I'm using an NSTreeController to manage nodes for an NSOutlineView. When the user adds a new item, I create a new object and insert it: EntityViewEntityNode *newNode = [EntityViewEntityNode nodeWithName:@"New entity" entity:newObject]; // Insert at end of group // NSIndexPath *insertAt = [pathOfGroupNode indexPathByAddingIndex:[selected.children count]]; [entityCollectionTreeController insertObject:newNode atArrangedObjectIndexPath:insertAt]; Now I'd like to open the table column for edit so the user can name the new item. This seems logical: NSInteger row = [entityCollectionOutlineView rowForItem:newNode]; [entityCollectionOutlineView editColumn:0 row:row withEvent:nil select:YES]; However, row is always -1 indicating the object isn't found. Poking around reveals that the tree controller is not actually putting my objects directly in the tree, but is wrapping them in a node object of its own. Anyone have insight into how I would go about getting a row index relative to the outline view, so I can do this (without, hopefully, enumerating everything in the outline view and figuring out the mapping back to my node?)

  • Design question what pattern to use

    - by rahul
    Problem Description: We have a requirement of storing the snapshot of an entity temporarily in the database untill a certain period of time untill all the processes to approve the data are completed. Once all approvals are completed the data shall be permanantly persisted into the actual table. Example: 1) Consider an entity called "User". One way to create the user is through the "Create Account Process". 2) The "Create Account Process" shall capture all the information of the User and store it in a temporary table in the database. 3) The data shall be used by the "Account Approval Process" to run its verification process. 4. After all the verification is completed successfully, the User data shall be persisted to the actual table. Question: Where to store the user data entered during "Create Account Process". Additionally, User data should be editable till the verification process is complete.

  • How can I pass a dynamic backing bean into a JSF 2.0 page using facelets?

    - by kgrad
    Hi, I am using a JSF 2.0 to create a web app (purely jee6, without spring/seam etc.). I would like to have a single xhtml page but pass the proper backing bean / entity into it. For example, I would like to be able to edit a user other than the logged in user, I have a user edit page which displays the information of the logged in user (being tracked by my session), I would like to instead pass in a user selected from a list and edit that user's information, without switching the user that is stored in the session or creating a separate xhtml page (violating DRY). The "best" way I can see to achieve this would be to reuse the exact same xhtml page that I am using to display the logged-in-user's edit page, but simply pass in a different entity in some way. Perhaps calling the setter in the backing bean before redirecting to the page (if this is even possible) or some other solution that does not violate DRY. Perhaps I have designed this all wrong, is there a way to pass in entities to JSF pages? thanks.

  • How to run unittest under pydev for Django?

    - by photon
    I configured properties for my django project under pydev. I can run the django app under pydev or under console window. I can also run unittest for app under console window. But I have problems to run unittest under pydev. I guess it's something related to run configurations of pydev, so I made several trials, but with no success. Once I got messages like this: ImportError: Could not import settings 'D:\django_projects\MyProject' (Is it on sys.path? Does it have syntax errors?): No module named D:\django_projects\MyProject ERROR: Module: MyUnittestFile could not be imported. Another time I got messages like this: ImportError: Could not import settings 'MyProject.settngs' (Is it on sys.path? Does it have syntax errors?): No module named settngs 'ERROR: Module: MyUnittestFile could not be imported. I use pydev 1.5.6 on eclipse and windows xp. Any ideas for this problem?

  • Binding Many-to-Many Core Data relationships in UI

    - by Kevin
    Basically my setup is this. I have a many-to-many relationship in Core Data where a student entity can have multiple courses, and a course entity can have multiple students. My problem is in trying to figure out how to bind this relationship to the UI in Interface Builder. I want to be able to add courses to a course array controller, then have those courses displayed in a popup menu in a NSTableView in the Edit Student window where you can add courses to a student. This is what I have so far: http://vimeo.com/10671726 It's probably easier to understand from the video. Thanks

  • Powerbuilder : How to compare the old value and new value of a column in data window

    - by Archangel
    Suppose I have a datawindow object which is attached to a datawindow control named 'dw_detail". This object uses grid presentation style and has a database column named 'found'. Now when a user modifies that column's value, I want to compare it with the original value that was fetched from the database. I know I can access the value of that column as 'dw_detail.object.found[row_no]'. Now I am trying to access the original value of the column as 'dw_detail.object.found.original[row_no]', but it is not working. It is not giving any compiling error, but when I debugged, 'dw_detail.object.found.original[row_no]' contains no values. How can I access the original value of that column?

  • Building a Hashtag in Javascript without matching Anchor Names, BBCode or Escaped Characters

    - by Martindale
    I would like to convert any instances of a hashtag in a String into a linked URL: #hashtag - should have "#hashtag" linked. This is a #hashtag - should have "#hashtag" linked. This is a [url=http://www.mysite.com/#name]named anchor[/url] - should not be linked. This isn&#39;t a pretty way to use quotes - should not be linked. Here is my current code: String.prototype.parseHashtag = function() { return this.replace(/[^&][#]+[A-Za-z0-9-_]+(?!])/, function(t) { var tag = t.replace("#","") return t.link("http://www.mysite.com/tag/"+tag); }); }; Currently, this appears to fix escaped characters (by excluding matches with the amperstand), handles named anchors, but it doesn't link the #hashtag if it's the first thing in the message, and it seems to grab include the 1-2 characters prior to the "#" in the link. Halp!
