  • Providing updates during a long Rails controller action

    - by highBandWidth
    I have an action that takes a long time. I want to be able to provide updates during the process so the user is not confused as to whether he lost the connection or something. Can I do something like this: class HeavyLiftingController < ApplicationController def data_mine render_update :js=>"alert('Just starting!')" # do some complicated find etc. render_update :js=>"alert('Found the records!')" # do some processing ... render_update :js=>"alert('Done processig')" # send @results to view end end

  • Best way to support large dropdowns

    - by JustAProgrammer
    Say I have a report that can be restricted by specifying some value in a dropdown. This dropdown list references a table with 30,000 records. I don't think this would be feasible to populate a dropdown with! So, what is the best way to provide the user the ability to select a value given this situation? These values do not really have categories and even if I subdivided (by having some nesting dropdown situation) by the first letter of the value, that may still leave a few thousand entries. What's the best way to deal with this?

  • JQuery works on JsFiddle but not in project

    - by DanielNova
    Here is the JsFiddle I created: http://jsfiddle.net/ShHVy/ Everything works fine - different data is displayed in the column row to the right as I wish.. However, even having this exact code in my Project won't make it work The page in question is a popup view and it looks like this: <style type="text/css"> .highlighted { background-color: Orange; color: White; } </style> <script> var chosen = []; $("td").click(function () { var idx = $(this).index() + 1; $("td:nth-child(" + idx + ")").removeClass("highlighted"); $(this).addClass("highlighted"); chosen[idx] = $(this).parent("tr").index(); }); var data = { "Differdange": ["Differdange 1", "Differdange 2", "Differdange 3", "Differdange 4"], "Dippach": ["Dippach 1", "Dippach 2", "Dippach 3", "Dippach 4", ] }; function pushData(id, col) { $("#datachange table td:nth-child(" + 2 + ")").each(function (i, v) { $(this).html(data[id][i]) }); } $(function () { $("#datachange td").click(function () { var idx = $(this).index() + 1; $("td:nth-child(" + idx + ")").removeClass("highlighted"); $(this).addClass("highlighted"); pushData($(".highlighted").html(), 2); }); }); </script> <html> <head><title>Table Data Change</title></head> <body id="datachange" class="demo"> <table> <thead> <tr> <th>ID</th> <th>DATA</th> </tr> </thead> <tbody> <tr> <td>Differdange</td> <td></td> </tr> <tr> <td>Dippach</td> <td></td> </tr> <tr> <td>Dippach</td> <td></td> </tr> <tr> <td>Differdange</td> <td></td> </tr> </tbody> </table> </body> </html> Can anyone tell me why this small piece of JQuery doesn't work on mine (it's nothing to do with libraries as the top "td" function works 100% fine)

  • Handling Model Inheritance in ASP.NET MVC2

    - by enth
    I've gotten myself stuck on how to handle inheritance in my model when it comes to my controllers/views. Basic Model: public class Procedure : Entity { public Procedure() { } public int Id { get; set; } public DateTime ProcedureDate { get; set; } public ProcedureType Type { get; set; } } public ProcedureA : Procedure { public double VariableA { get; set; } public int VariableB { get; set; } public int Total { get; set; } } public ProcedureB : Procedure { public int Score { get; set; } } etc... many of different procedures eventually. So, I do things like list all the procedures: public class ProcedureController : Controller { public virtual ActionResult List() { IEnumerable<Procedure> procedures = _repository.GetAll(); return View(procedures); } } but now I'm kinda stuck. Basically, from the list page, I need to link to pages where the specific subclass details can be viewed/edited and I'm not sure what the best strategy is. I thought I could add an action on the ProcedureController that would conjure up the right subclass by dynamically figuring out what repository to use and loading the subclass to pass to the view. I had to store the class in the ProcedureType object. I had to create/implement a non-generic IRepository since I can't dynamically cast to a generic one. public virtual ActionResult Details(int procedureID) { Procedure procedure = _repository.GetById(procedureID, false); string className = procedure.Type.Class; Type type = Type.GetType(className, true); Type repositoryType = typeof (IRepository<>).MakeGenericType(type); var repository = (IRepository)DependencyRegistrar.Resolve(repositoryType); Entity procedure = repository.GetById(procedureID, false); return View(procedure); } I haven't even started sorting out how the view is going to determine which partial to load to display the subclass details. I'm wondering if this is a good approach? This makes determining the URL easy. It makes reusing the Procedure display code easy. Another approach is specific controllers for each subclass. It simplifies the controller code, but also means many simple controllers for the many procedure subclasses. Can work out the shared Procedure details with a partial view. How to get to construct the URL to get to the controller/action in the first place? Time to not think about it. Hopefully someone can show me the light. Thanks in advance.

  • How to test that action uses argument?

    - by Caster Troy
    I am supposed to be using test-driven development but in this particular case, as I am having trouble, I implemented the action method first. It looks like this: public ViewResult Index(int pageNumber = 1) { var posts = repository.All(); var model = new PagedList<Post>(posts, pageNumber, PageSize); return View(model); } Both the repository and the PagedList<> have been tested already. Now I want to verify that when the action is given a page number that the page number is actually considered. private Mock<IPostsRepository> repository; private HomeController controller; [Test] public void Index_Doohickey() { var actual = controller.Index(2); // .. How do I test that the controller actually uses the page number here? }

  • How to trigger the specific controller action using a button?

    - by Eugene
    I'm creating a simple training project. I've implemented a controller method, which deletes an item from the list. The method is looking like this: @Controller @RequestMapping(value = "/topic") public class TopicController { @Autowired private TopicService service; ... @RequestMapping(value = "/deleteComment/{commentId}", method = RequestMethod.POST) public String deleteComment(@PathVariable int commentId, BindingResult result, Model model){ Comment deletedComment = commentService.findCommentByID(commentId); if (deletedComment != null) { commentService.deleteComment(deletedComment); } return "refresh:"; } } This method is called from the button-tag, which is looking in the following way: _form> _button formaction = "../deleteComment/1" formmethod = "post">delete_/button> _/form> Sorry, but in the form tag I've changed all the '<' characters with the '_', because the tag was invisible. In my project the form-tag is looking like a cliuckable button. But there is a serious problem: controller's method is never triggered. How can I trigger it, using a button-tag? P.S. the call is performed from the page with URI http://localhost:8080/simpleblog/topic/details/2 and controller's URI is the http://localhost:8080/simpleblog/topic/deleteComment/2

  • Rails - Update a single attribute : link with custom action or form with hidden fields?

    - by MrRuru
    Let's say I have a User model, with a facebook_uid field corresponding to the user's facebook id. I want to allow the user to unlink his facebook account. Do do so, I need to set this attribute to nil. I currently see 2 ways of doing this First way : create a custom action and link to it # app/controllers/users_controller.rb def unlink_facebook_account @user = User.find params[:id] # Authorization checks go here @user.facebook_uid = nil @user.save # Redirection go here end # config/routes.rb ressources :users do get 'unlink_fb', :on => :member, :as => unlink_fb end # in a view = link_to "Unlink your facebook account", unlink_fb_path(@user) Second way : create a form to the existing update action # app/views/user/_unlink_fb_form.html.haml = form_for @user, :method => "post" do |f| = f.hidden_field :facebook_uid, :value => nil = f.submit "Unlink Facebook account" I'm not a big fan of either way. In the first one, I have to add a new action for something that the update controller already can do. In the second one, I cannot set the facebook_uid to nil without customizing the update action, and I cannot have a link instead of a button without adding some javascript. Still, what would you recommend as the best and most elegant solution for this context? Did I miss a third alternative?

  • If cookie found, get data, else create cookie, is this good logic?

    - by Ryan
    I have an Action that basically adds an item to a cart, the only way the cart is known is by checking the cookie, here is the flow of logic, please let me know if you see any issue... /order/add/[id] is called via GET action checks for cookie, if no cookie found, it makes a new cart, writes the identifier to the cookie, and adds the item to the database with a relation to the cart created if cookie is found, it gets the cart identifier from the cookie, gets the cart object, adds the item to the database with a relation to the cart found so it's basically like... action add(int id){ if(cookie is there) cart = getcart(cookievalue) else cart = makecart() createcookie(cart.id) additemtocart(cart.id, id) return "success"; } Seem right? I can't really thing of another way that would make sense.

  • LINQ to Entites: Doing a count over one-to-many relationships

    - by chris
    I have a couple of tables where there are one to many relationships. Let's say I have a Country table, a State table with a FK to Country, and a City table with a FK to State. I'd like to be able to create a count of all Cities for a given country, and also a count of cities based on a filter - something like: foreach( var country in Model.Country ) { total = country.State.All().City.All().Count() ; filtered = country.State.All().City.Any(c=>c.field == value).Count(); } Obviously, this doesn't work - is there any way to do this?

  • Creating non-framework calsses in CakePHP

    - by Affian
    I'm making a tournament manager in CakePHP 1.3 and I have a tournament controller which is fine but I want to implement a interface that can be used to define how a tournament runs. the controller needs to load a concrete class that implements the TournamentStyle interface that defines how the tournament works. At the end of a round the TournamentStyle is used to calculate the scores and winners and generate the next round of matches. That gives me a .php file for the interface and other files for the various styles. My question is: where would I put these files and how would I load them into my tournament controller?

  • Calling a function in a JavaScript file with Selenium IDE

    - by user1059903
    So, I'm running these Selenium IDE tests against a site I'm working on. Everything about the tests themselves is running fine, except I would like to do a bit of clean-up once I'm done. In my MVC3 Razor based site, I have a JavaScript file with a function that gets a JsonResult from a Controller of mine. That Controller handles the database clean-up that Selenium IDE otherwise couldn't handle. However, I'm having a hard time finding any sort of documentation on how to do this. I know I can do JavaScript{ myJavascriptGoesHere } as one of the Values for a line in the test, but I can't seem to find a way to tell it to go find my clean-up function. Is it even possible for Selenium IDE to do this sort of thing? If it comes down to it, I can just make a separate View to handle the clean-up, but I'd really like to avoid that if possible. Thanks!

  • Render view as string when Ajax request to view is made

    - by mare
    I have my views render to route requests like /controller/action (for instance, /Page/Create), so pretty classic. I am creating a form where view will be loaded through AJAX request with jQuery get(), so essentially I need my Views or to be precise, my controller actions, to return plain HTML string when an AJAX request is made to the route that renders the View. I want to use the same views as for normal requests, so I cannot afford to create any new views. It is something like calling RenderPartial("MyViewUserControl") but from inside the JS code.

  • MVC2 JSON action, if I want to be RESTful should I allow GET, POST, or Both?

    - by Yads
    The project I'm currently working has a whole bunch of JSON actions in order to populate cascading dropdowns via ajax calls. Since they're technically Select queries and we're trying to be RESTful, we've been marking these actions with the HttpGet attributes. However by default, JsonResultdoes not allow to return results via a GET. So we've had to explicitly call Json(data, JsonRequestBehavior.AllowGet). What I'm wondering is, is this bad practice? Should we only be allowing Post requests to our Json actions? If it makes a difference, this is an enterprise application, that requires a log in to a particular environment before it can be accessed.
