  • How to dynamically order many-to-many relationship in JPA or HQl?

    - by Indrek
    I have a mapping like this: @ManyToMany(cascade = CascadeType.PERSIST) @JoinTable( name="product_product_catalog", joinColumns={@JoinColumn(name="product_catalog", referencedColumnName="product_catalog")}, inverseJoinColumns={@JoinColumn(name="product", referencedColumnName="product")}) public List<Product> products = new ArrayList<Product>(); I can fetch the products for the catalog nicely, but I can't (dynamically) order the products. How could I order them? I probably have to write a many-to-many HQL query with the order-by clause? I though of passing the orderBy field name string to the query, or is there a better solution? Tables are: products, product_catalog, product_product_catalog (associative table) P.S. Using Play! Framework JPASupport for my entities.

  • Ruby Rails _without_ ActiveRecord

    - by devlearn
    Hello, I'm looking for any pointers on how to write a rails web app without ActiveRecord. A doc or an example of a (not too complex) web app using storage backends other than a relational database would be greatly appreciated. It's not clear on what should be implemented in the model classes in order to make the rails app work without the ActiveRecord layer. Thanks,

  • Sending bulk notification emails without blocking

    - by FreshCode
    For my client's custom-built CRM, I want users (technicians) to be notified of changes to marked cases via email. This warrants a simple subscription mapping table between users and cases and automated emails to be sent every time a change is made to a case from within the logging method. How do I send 10-100 emails to subscribed users without bogging down my logging method? My SMTP server is on a peer on my LAN, so sends should be quick, but ideally this should be handled by an external queuing process. I can have a cron job send any outstanding emails every 10 minutes, but for this specific client cases are quite time-sensitive and instant notification (as instant as email can be) would be great. How can I send bulk notification emails from within ASP.NET MVC without bogging down my logging method?

  • Table-per-type inheritance insert problem

    - by gzak
    I followed this article on making a table-per-type inheritance model for my entities, but I get the following error when I try to add an instance of a subclass to the database. Here is how I create the subtype: var cust = db.Users.CreateObject<Customer>(); // Customer inherits User db.Users.AddObject(cust); db.SaveChanges(); I get the following error when I make that last call: "A value shared across entities or associations is generated in more than one location. Check that mapping does not split an EntityKey to multiple store-generated columns." With the following inner exception: "An item with the same key has already been added." Any ideas on what I could be missing?

  • Nesting forms in CakePHP

    - by Erik
    I am wondering if there's a way in CakePHP to nest multiple models in a form? What I'm trying to accomplish is to make a form for creating Posts that will also contain fields for adding Images (separate model) that will automatically be connected to the created post. Something similar to Ruby on Rails ** accept_nested_attributes_for**.

  • Bypass using Alter Access Mappings for to Open Web from SPItemEventProperties

    - by Greg Ogle
    In the following code, // class overrides SPItemEventreceiver public override void ItemAdding(SPItemEventProperties properties) { using (var site = new SPSite(properties.SiteId)) //SiteId is integer { ... } } The following exception is thrown: System.IO.FileNotFoundException: The Web application at http://URL could not be found. Verify that you have typed the URL correctly. If the URL should be serving existing content, the system administrator may need to add a new request URL mapping to the intended application. One way to work around this is to hard-code (or configure) the URL specified in Alternate Access Mappings. Putting the correct URL in Alternate Access Mappings is ultimately the correct solution, but if possible, I need a work-around that doesn't require configuration.

  • fluent nhibernate not caching queries in asp.net mvc

    - by AWC
    I'm using a fluent nhibernate with asp.net mvc and I not seeing anything been cached when making queries against the database. I'm not currently using an L2 cache implementation. Should I see queries being cached without configuring an out of process L2 cache? Mapping are like this: Table("ApplicationCategories"); Not.LazyLoad(); Cache.ReadWrite().IncludeAll(); Id(x => x.Id); Map(x => x.Name).Not.Nullable(); Map(x => x.Description).Nullable(); Example Criteria: return session .CreateCriteria<ApplicationCategory>() .Add(Restrictions.Eq("Name", _name)) .SetCacheable(true); Everytime I make a request for an application cateogry by name it is hitting the database is this expected behaviour?

  • hibernate versioning parent entity

    - by Priit
    Consider two entities Parent and Child. Child is part of Parent's transient collection Child has a ManyToOne mapping to parent with FetchType.LAZY Both are displayed on the same form to a user. When user saves the data we first update Parent instance and then Child collection (both using merge). Now comes the tricky part. When user modifies only Child property on the form then hibernate dirty checking does not update Parent instance and thus does not increase optimistic locking version number for that entity. I would like to see situation where only Parent is versioned and every time I call merge for Parent then version is always updated even if actual update is not executed in db.

  • Passing HttpFileCollectionBase to the Business Layer - Bad?

    - by Terry_Brown
    hopefully there's an easy solution to this one. I have my MVC2 project which allows uploads of files on certain forms. I'm trying to keep my controllers lean, and handle the processing within the business layer of this sort of thing. That said, HttpFileCollectionBase is obviously in the System.Web assembly. Ideally I want to call to something like: UserService.SaveEvidenceFiles(MyUser user, HttpFileCollectionBase files); or something similar and have my business layer handle the logic of how and where these things are saved. But, it feels a little icky to have my models layer with a reference to System.Web in terms of separation of concerns etc. So, we have (that I'm aware of) a few options: the web project handling this, and my controllers getting fatter mapping the HttpFileCollectionBase to something my business layer likes passing the collection through, and accepting that I reference System.Web from my business project Would love some feedback here on best practice approaches to this sort of thing - even if not specifically within the context of the above.

  • How to give the First image in a gallery a different class than the rest of the images - Carrierwave

    - by ChrisBedoya
    I have a model called "Photo" that belongs to a model called "Shoe". I using Carrierwave to upload multiple images. index.html.erb <% shoes.each do |shoe| %> <div class="shoe"> <div class="gallery"> <% shoe.photos.each do |photo| %> <%= link_to image_tag(photo.photo_file.url(:thumb).to_s), photo.photo_file.url.to_s, :class => 'fancybox', :rel => 'gallery' %> <% end %> </div> </div> <% end %> Outputs this: <div class="shoe"> <div class="gallery"> <a class="fancybox" href="../nike-kd-6-meteorology-2.jpg" rel="gallery"> <img src="../thumb_nike-kd-6-meteorology-2.jpg"> </a> <a class="fancybox" href="../nike-kd-6-meteorology-2.jpg" rel="gallery"> <img src="../thumb_nike-kd-6-meteorology-2.jpg"> </a> <a class="fancybox" href="../nike-kd-6-meteorology-2.jpg" rel="gallery"> <img src="../thumb_nike-kd-6-meteorology-2.jpg"> </a> </div> </div> But I want the first image of each gallery to be able to have its own class and the rest of the images to have their own class. Something like this: <a class="firstclass" href="../nike-kd-6-meteorology-2.jpg" rel="gallery"> <img src="../thumb_nike-kd-6-meteorology-2.jpg"> </a> <a class="fancybox" href="../nike-kd-6-meteorology-2.jpg" rel="gallery"> <img src="../thumb_nike-kd-6-meteorology-2.jpg"> </a> <a class="fancybox" href="../nike-kd-6-meteorology-2.jpg" rel="gallery"> <img src="../thumb_nike-kd-6-meteorology-2.jpg"> </a> How can I do this? Also I want each gallery to have its own unique id but when I try to add this: :rel => 'gallery<%= shoe.id %>' I get a Syntax error. Thanks.

  • How can I override the attribute assignment in an active record object?

    - by ryeguy
    I know you can do this with virtual attributes, but what if the column actually exists? For example, my model has a raw_topic column. When raw_topic is set, I want artist and song_title to be set based off of raw_topic's contents. Ideally, I'd like to override the raw_topic= method, but rails doesn't seem to like that. What's the proper way of doing this? Is a callback the only way?

  • Adding a subdomain to my google app engine project?

    - by user246114
    Hi, I created a google app engine project. I just successfully mapped it to a new domain. The name of my project is "grape". So by default, it is published at http://www.grape.appspot.com. I mapped it to http://www.grape.com, which is terrific. Now I'd like to create a new app engine project, and have it mapped to: http://api.grape.com how do I go about doing this? I think it is possible, I'm just not sure where I would do this mapping? Since I own grape.com, I am hoping I can map a new project to t. The basic idea was to have one project which is responsible for the UI stuff, then a second project responsible just for a public api, which would be great, Thanks

  • Scaffold is ignoring class file in CakePHP

    - by JoseMarmolejos
    Hi, when using scaffolding on a controller the views render fine and the app even attempts to insert the data; the problem is that the scaffold is completely ignoring the relations I'm defining in my model class, in fact it's ignoring the class entirely as I can delete the file and the controller still scaffolds and render the crud from the table. Has this ever happened to you?
