  • Getting field of type bytea in helper table when using GenerationType.IDENTITY

    - by dtrunk
    I'm creating my db scheme using Hibernate. There's a Table called "tbl_articles" and another one called "tbl_categories". To have a n-n relationship a helper table ("tbl_articles_categories") is needed. Here are all necessary Entities: @Entity @Table( name = "tbl_articles" ) public class Article implements Serializable { private static final long serialVersionUID = 1L; @Id @Column( nullable = false ) @GeneratedValue( strategy = GenerationType.IDENTITY ) private Integer id; // other fields... public Integer getId() { return id; } public void setId( Integer id ) { this.id = id; } // other fields... } @Entity @Table( name = "tbl_categories" ) public class Category implements Serializable { private static final long serialVersionUID = 1L; @Id @Column( nullable = false ) @GeneratedValue( strategy = GenerationType.IDENTITY ) private Integer id; // other fields public Integer getId() { return id; } public void setId( Integer id ) { this.id = id; } // other fields... } @Entity @Table( name = "tbl_articles_categories" ) @AssociationOverrides({ @AssociationOverride( name = "pk.article", joinColumns = @JoinColumn( name = "article_id" ) ), @AssociationOverride( name = "pk.category", joinColumns = @JoinColumn( name = "category_id" ) ) }) public class ArticleCategory { private ArticleCategoryPK pk = new ArticleCategoryPK(); public void setPk( ArticleCategoryPK pk ) { this.pk = pk; } @EmbeddedId public ArticleCategoryPK getPk() { return pk; } @Transient public Article getArticle() { return pk.getArticle(); } public void setArticle( Article article ) { pk.setArticle( article ); } @Transient public Category getCategory() { return pk.getCategory(); } public void setCategory( Category category ) { pk.setCategory( category ); } } @Embeddable public class ArticleCategoryPK implements Serializable { private static final long serialVersionUID = 1L; @ManyToOne @ForeignKey( name = "tbl_articles_categories_fkey_article_id" ) private Article article; @ManyToOne @ForeignKey( name = "tbl_articles_categories_fkey_category_id" ) private Category category; public ArticleCategoryPK( Article article, Category category ) { setArticle( article ); setCategory( category ); } public ArticleCategoryPK() { } public Article getArticle() { return article; } public void setArticle( Article article ) { this.article = article; } public Category getCategory() { return category; } public void setCategory( Category category ) { this.category = category; } } Now, I'm getting a serial type what I wanted in my articles table as well as in my categories table. But looking into my helper table, there aren't the expected fields article_id and category_id each of type integer - instead there are article and category of type bytea. What's wrong here? EDIT: Sorry, forgot to mention that I'm using PostgreSQL.

  • ASP.NET MVC Referencing Html Helper from a view

    - by Dan
    I've written an Html Helper called DetailsForm to reduce repetition when displaying fields in a view. Within a view - actually a partial view, ascx file - I can refer to it like this: Storyboard.Helpers.DetailsForm.LabelAndData(Html, m => m.id) But would like to refer to it like this: LabelAndData(Html, m => m.id) A 'using' directive doesn't seem to be allowed in the ascx file. Is there an equivalent?

  • How to create a subject helper method in Rspec2

    - by Hedgehog
    In rpsec 2.12 I expected this helper method definition to work: module X private def build_them(type) puts 'Catching the star' end end context 'public/private instance methods' do subject{ Class.new { extend(::X) } } def subject.build(type) puts "Throwing a star" build_them(type) end it{ should respond_to :build} end The actual result is a failed spec: expected #<Class:0x00000002ea5f90> to respond to :build I expected the example to pass Any suggestions on how to do this correctly?

  • build-helper-maven-plugin add-source does not working when trying to add linked resources

    - by Julian
    I am new to maven and hit a problem that looks easy in the first place but I already kept me busy for a whole day about and no way to get it working. First as part of running eclipse:eclipse plugin I create a linked folder like below: <linkedResources> <linkedResource> <name>properties</name> <type>2</type> <location>${PARENT-2-PROJECT_LOC}/some_other_project/properties</location> </linkedResource> <linkedResource> <name>properties/messages.properties</name> <type>1</type> <location>${PARENT-2-PROJECT_LOC}/some_other_project/properties/messages.properties</location> </linkedResource> And then I am adding that folder as a source folder like below: <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>build-helper-maven-plugin</artifactId> <version>1.7</version> <executions> <execution> <id>add-source</id> <phase>generate-sources</phase> <goals> <goal>add-source</goal> </goals> <configuration> <sources> <source>properties</source> <source>some_real_folder</source> </sources> </configuration> </execution> </executions> </plugin> However when I am looking at the generated .classpath in eclipse the “some_real_folder” is there but the “properties” is not. It looks like by default the build-helper-maven-plugin will check if the folder is there and if it is not it won’t add it. I am using maven 3.0.4 outside eclipse to run the build and I can see in the maven logs something like this: [INFO] Source directory: <some path>\properties added. This is my project structure: project1 \-- properties (this is the real folder) project2 \-- some_real_folder \-- properties (this is the link resource pointing to the project1/properties folder) All I need is to have both "some_real_folder" and the linked resource "properties" added to the .classpath of the project2

  • breaking datetime into constituent parts ASP.NET MVC form

    - by nick
    hi guys, i have searched the web relentlessly for this and have not found anything - which is surprising because i would think it is such a common scenario! Basically, on my model i have a DateTime field which i wish the user to populate through a form. I am using the Html helper to render all other parts of the form (along with validation) So this question is in two parts... Html Helper Firstly, is there any way to use the Html helper to split the DateTime field to be rendered as the three constituent parts of a date: day, month, year (since i do not care about the time part). This could be rendered as text boxes, drop down lists or a combination of both. Model Binding And then when the form is posted, what is the best approach for binding back up to the model? I have seen Scott Hanselmann's solution to this, but it seems a little bloated for what i need - i was hoping for a slightly more elegant solution. Is it recommended to extend DefaultModelBinder and set that as default binder (since all dates would be handled in this way) or write a class that implements IModelBionder and set it as the default binder for the DateTime type? Thanks for all the help in advance :-) i'm loving MVC but it's infuriating me that something so trivial is causing so much headaches!

  • Magento Onepage Success Conversion Tracking Design Pattern

    - by user1734954
    My intent is to track conversions through multiple channels by inserting third party javascript (for example google analytics, optimizely, pricegrabber etc.) into the footer of onepage success . I've accomplished this by adding a block to the footer reference inside of the checkout success node within local.xml and everything works appropriately. My questions are more about efficiency and extensibility. It occurred to me that it would be better to combine all of the blocks into a single block reference and then use a various methods acting on a single call to the various related models to provide the data needed for insertion into the javascript for each of the conversion tracking scripts. Some examples of the common data that conversion tracking may rely on(pseudo): Order ID , Order Total, Order.LineItem.Name(foreach) and so on Currently for each of the scripts I've made a call to the appropriate model passing the customers last order id as the load value and the calling a get() assigning the return value to a variable and then iterating through the data to match the values with the expectations of the given third party service. All of the data should be pulled once when checkout is complete each third party services may expect different data in different formats Here is an example of one of the conversion tracking template files which loads at the footer of checkout success. $order = Mage::getModel('sales/order')->loadByIncrementId(Mage::getSingleton('checkout/session')->getLastRealOrderId()); $amount = number_format($order->getGrandTotal(),2); $customer = Mage::helper('customer')->getCustomer()->getData(); ?> <script type="text/javascript"> popup_email = '<?php echo($customer['email']);?>'; popup_order_number = '<?php echo $this->getOrderId() ?>'; </script> <!-- PriceGrabber Merchant Evaluation Code --> <script type="text/javascript" charset="UTF-8" src="https://www.pricegrabber.com/rating_merchrevpopjs.php?retid=<something>"></script> <noscript><a href="http://www.pricegrabber.com/rating_merchrev.php?retid=<something>" target=_blank> <img src="https://images.pricegrabber.com/images/mr_noprize.jpg" border="0" width="272" height="238" alt="Merchant Evaluation"></a></noscript> <!-- End PriceGrabber Code --> Having just a single piece of code like this is not that big of a deal, but we are doing similar things with a number of different third party services. Pricegrabber is one of the simpler examples. A more sophisticated tracking service expects a comma separated list of all of the product names, ids, prices, categories , order id etc. I would like to make it all more manageable so my idea to do the following: combine all of the template files into a single file Develop a helper class or library to deliver the data to the conversion template Goals Include Extensibility Minimal Model Calls Minimal Method Calls The Questions 1. Is a Mage helper the best route to take? 2. Is there any design pattern you may recommend for the "helper" class? 3. Why would this the design pattern you've chosen be best for this instance?

  • jQuery UI sortable scroll helper element offset Firefox issue

    - by James
    I have a problem with a jQuery UI 1.7.2 sortable list in Firefox 3.6, IE7-8 work fine. When I'm scrolled down a bit, the helper element seems to have an offset of the same height that I'm scrolled down from the mouse pointer which makes it impossible to see which item you originally started dragging. How do I fix this or work around the issue? If there is no fix what is a really good alternative drag-able plugin? Here are my initialization parameters for the sortable. $("#sortable").sortable( {placeholder: 'ui-state-highlight' } ); $("#sortable").disableSelection();

  • jQuery UI sortable('cancel') - this.helper is null

    - by Kerry
    I am trying to disable a sortable element from sorting when it has been double clicked. When I try to disable it, even without a condition, it gives me the error 'this.helper is null'. $('.roundedBox:first', division).sortable({ start: function( event, ui ) { if( true === true ) { $(this).sortable('cancel'); } $(this).parent().data( 'sorting', true ); }, stop: function() { $(this).parent().data( 'sorting', false ); }, items: '.department', update: function() {}, placeholder: 'department-placeholder' }) Any ideas on how I can do this? I don't need it to be this method. Literally anything thing that stops it will work. The problem is, sorting starts on a single click, but I have another action bound to double click. If it's double clicked, I don't want it to drag.

  • Helper Casting Functions -- Is it a code smell?

    - by Earlz
    I recently began to start using functions to make casting easier on my fingers for one instance I had something like this ((Dictionary<string,string>)value).Add(foo); and converted it to a tiny little helper function so I can do this ToDictionary(value).Add(foo); Is this a code smell? Also, what about simpler examples? For example in my scripting engine I've considered making things like this ((StringVariable)arg).Value="foo"; be ToStringVar(arg).Value="foo"; I really just dislike how inorder to cast a value and instantly get a property from it you must enclose it in double parentheses. I have a feeling the last one is much worse than the first one though (also I've marked this language agnostic even though my example is C#)

  • c#: IsNullableType helper class ?

    - by mark smith
    Hi there, Can anyone help? I have some code that is shared between 2 projects. The code points to a model which basically is a collection of properties that comes from a db. Problem being is that some properties use nullable types in 1 model and the other it doesn't Really the dbs should use the same but they don't .. so for example there is a property called IsAvailble which uses "bool" in one model and the other it uses bool? (nullable type) so in my code i do the following objContract.IsAvailble.Value ? "Yes" : "No" //notice the property .VALUE as its a bool? (nullable type) but this line will fail on model that uses a standard "bool" (not nullable) as there is no property .VALUE on types that are NOT nullable Is there some kind of helper class that i check if the property is a nullable type and i can return .Value .. otherwise i just return the property. Anybody have a solution for this?

  • Database Version Control SQL Server 2008 Drop SP's and Functions

    - by Lieven Cardoen
    I'm working on versioning our database and now searching for a way to drop all stored procedures and functions from a C# Console Application. I'd rather not create a stored procedure that drops all stored procedures and functions. I has to be some sql executed from C#. I tried to drop the stored procedure before creating it, but I get this message: System.Data.SqlClient.SqlException: 'CREATE/ALTER PROCEDURE' must be the first statement in a query batch. Script for one SP for example: DROP PROCEDURE [dbo].[sp_Economatic_LoadJournalEntryFeedbackByData] SET ANSI_NULLS ON SET QUOTED_IDENTIFIER ON CREATE PROCEDURE [dbo].[sp_Economatic_LoadJournalEntryFeedbackByData] @Data VARCHAR(MAX) AS BEGIN ... END So I guess before creating all SP's and functions I'll need to drop all SP's and functions first with one sql script.

  • Browser Helper Object doesnot get loaded in IE8

    - by velusbits
    I have a BHO, which i can see it as enabled in Add On's list. But it does not get loaded when i start my IE on the Win2k8 R2 machines(64 bit). I have disabled IE Enhanced security as well but no help. The same BHO gets loaded in other machines. The registry details under (HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects & HKEY_CLASSES_ROOT\Wow6432Node\CLSID) seem to be fine. Is there any setting that disables BHO from actually getting loaded?
