• In Ruby on Rails Routing I Would Like to Use Dash `-` Instead of Underscore `_`

  - by pablitostar

  I would like all the URLs for my web applications to use dash - instead of underscore _ for word separators. I'm surprised about a couple of things really: Google et al. continue to distinguish them. That RoR doesn't have a simple global configuration parameter to map - to _ in the routing. Or does it? I found a few questions here and elsewhere, but the best solution I've seen is to use :as or a named route. That's quite annoying. So I'm thinking of modifying the Rails routing to check for that global config and change - to _ before dispatching to a controller action. But before I do that, I'm hoping someone can save me the trouble! Thanks in advance for any help, or even confirmation that my approach makes sense. I'd submit it back. BTW, I'm currently on 2.3.8, but hope to migrate to 3 soon.

• How do I check if an instance has an object to skip displaying the values?

  - by Angela

  I have created a polymorphic association around a model called status. Some contacts will have a status associated with it. Many won't. If I try to call a status when one is not there, I get an error. Right now, even if I haven't created a status for the model, it still runs whatever is in the if-end block. Here's what I am trying, but it's not working: <% if [email protected]? %> <p>Status: <%= @status.find(:last).status %></p> <% end %> In the controller, it is defined below: @status = Contact.find(@contact).statuses By the way, also open to make code more readable and DRY.

• Storing Object Types in Variable then Initializing

  - by Jon Mattingly

  Is there a way in Objective-C to store an object/class in a variable to be passed to alloc/init somewhere else? For example: UIViewController = foo foo *bar = [[foo alloc] init] I'm trying to create a system to dynamically create navigation buttons in a separate class based on the current view controller. I can pass 'self' to the method, but the variable that results does not allow me to alloc/init. I could always import the .h file directly, but ideally I would like to make reusing the code as simple as possible. Maybe I'm going about this the wrong way?

• Need a push in the write direction, to write my first functional test in Rails?

  - by Jason

  Hi, I've read quiet a bit of documentation over the last few days about testing in Rails, I'm sitting down to write my first real test and not 100% sure how to tie what I have learned together to achieve the following functional test (testing a controller) I need to send a GET request to a URL and pass 3 parameters (simple web-service), if the functionality works the keyword "true" is simply returned, otherwise the keyword "false" is returned - its in only value returned & not contained in any , or other tags. The test should assert that if "true" is returned the test is successful. This is probably very simple so apologies for such a non-challenging question. If anyone could point me in the write direction on how I can get started, particularly how I can test the response, I'd be very grateful! Thanks!

• Spring 3 - Theme with separate JSP

  - by Max

  Hi, I'm trying to rewrite some Spring 1.2 code to Spring 3.0 one. Currently I'm stuck with JSP resolved by URL problem. Application uses separate JSP files with different layouts for serving the same model from the same controller. The JSP is switched using interceptor, that intercepts the url and changes the view. For example: /design_one/mypage.htm -> MyPageController -> /design_one/mypage.jsp /design_two/mypage.htm -> MyPageController -> /design_two/mypage.jsp Is there a way to make same or similar functionality using something better than raw interceptors?

• RequireHttpsAttribute and Encrypted Request Data

  - by goatshepard

  I have a controller action that is accepting sensitive data. public ActionResult TakeSensitiveData(SensitiveData data){ data.SaveSomewhere(); } To ensure the data is secure I want to be certain requests are made using HTTPS (SSLv3, TLS 1). One of the approaches I've considered using was the RequireHttpsAttribute on my action: [RequireHttps] public ActionResult TakeSensitiveData(SensitiveData data){ data.SaveSomewhere(); } However, upon testing this I fiddler revealed that an HTTP request made to the action is 302 redirected to HTTPS. My question is this: If I've made a request that is 302 redirected to HTTPS haven't I already sent the sensitive data over HTTP before the redirect?

• How to pass object in :with field for a link_to_remote call

  - by mathee

  I have an object elem that I'd like to pass to the remove_tag_from_cart method. Here is my attempt: -elem = @tags[1] #{elem.name}#{link_to_remote image_tag('x.png'), :url => {:controller => 'questions', :action => 'remove_tag_from_cart'}, :with => {:tag_to_remove => :elem}} The :with clause isn't working correctly. The image does not even show up. If I take out the :with clause, then the link properly shows up and calls the method correctly, but I need the elem object in order to remove it from the cart. Suggestions?

• Showing an image after loading it from sql database

  - by user330075

  I have a problem showing the image form database in a view Details and a ImageController. Inside the view I have: img src=Url.Action("GetFile","Image", new {id= Model.id}) and in controller: public FileContentResult GetFile(int idl) { //int idl = 32; SqlDataReader rdr; byte[] fileContent = null; ........... return File(,,); } When the view is called, function GetFile it just won't work. But if I cut out the parameter int id1 and I instantiate it as a variable it does work. public FileContentResult GetFile() { int idl = 32; SqlDataReader rdr; byte[] fileContent = null; ........... return File(,,); } Why?

• Code Interaction with Quartz Composition

  - by Alberto MQO

  Hi, i have a Quartz Composition with a Cube, and X/Y/Z rotation inputs are published. On Interface Builder i made a QCView and a QCPatchController with the previous Quartz Composition loaded. In QCView the Patch Controller is binded, and the rotation published ports are binded too to three NSSlider, so when i change the value of the NSSlider's then the cube rotates. All this works fine, but i want to change the rotation values of the cube from the App Delegate on XCode. I tried to change the value of the NSSliders with IBoulets pointing to them, but this change doesnt apply to the cube, like it does when i change the Sliders directly with my mouse. What should i instanciate and/or how to access and change this Input_Ports.value throught the CQPatchController? Thank you very much for reading, i really need help!

• How do I make a Java ResultSet available in my jsp?

  - by melling

  I'd like to swap out an sql:query for some Java code that builds a complex query with several parameters. The current sql is a simple select. <sql:query var="result" dataSource="${dSource}" sql="select * from TABLE " </sql:query How do I take my Java ResultSet (ie. rs = stmt.executeQuery(sql);) and make the results available in my JSP so I can do this textbook JSP? To be more clear, I want to remove the above query and replace it with Java. <% ResultSet rs = stmt.executeQuery(sql); // Messy code will be in some Controller % <c:forEach var="row" items="${result.rows}" <c:out value="${row.name}"/ </c:forEach Do I set the session/page variable in the Java section or is there some EL trick that I can use to access the variable?

• Inheritance in kohana

  - by Binaryrespawn

  Hi all, I have recently started to use Kohana and I know inheritance is in infancy stages at the moment. The work around is using a $_has_one annotation on the child class model. In may case i have "page" as the parent of "article". I have something like, protected $_has_one = array('mypage'=>array('model'=>'page', 'foreign_key'=>'id')); In my controller, I have an action which queries the database. In this query I am trying to access fields form the parent of "article" which is the "page". $n->articles=ORM::factory('article')->where('expires','=',0) ->where('articledate','<',date('y-m-d')) ->where('expirydate','>',date('y-m-d')) ->where('mypage->status','=','PUBLISHED') ->order_by('articledate','desc') ->find_all(); The status column resides in the page table and my query is generating an error to the effect of "cannot find status", clearly because it belongs to the parent. Any ideas ?

• Is there a variable in Rails that equates to the template that is being rendered?

  - by Sean Ahrens

  I can do request.path_parameters['controller'] and request.path_parameters['action'], but is there anything like request.path_parameters['template'] so I can discern which template file (such as index.html.erb) is being rendered? I'm writing a method that automatically sets the body id to the template being rendered, for easy css manipulation: class ApplicationController < ActionController::Base ... after_filter :define_body_selector ... def define_body_selector # sets @body_id to the name of the template that will be rendered # ie. if users/index.html.erb was just rendered, @body_id gets set to "index" @body_id = ??? end ...

• Grails design for domain class initialization from static data

  - by Allison Eer

  I have some data, stateNames, to instantiate an instance of the object Country. Right now, I will only have one Country but stateNames for each country should be different. What is the best way to instantiate the instance of Country with my data? I am new to grails and would appreciate any "best practices" or common designs. One solution I can think of is to use BootStrap to save the unitedStates instance of Country to the database. What are the cons of this approach? Another solution would be to save the data in a file (in xml?) under web-app folder. If I did this approach, should the unitedStates instance of Country be instantiated by a controller?

• problem with dropdownlist in mvc application

  - by czuroski

  Hello, I am trying to work with an HTML.DropDownList in MVC and am not getting the expected return values. Here is my implementation for the selectList to bind to the drop down - IEnumerable<status> stat = _provider.GetAllStatuses(); Statuses = new SelectList(stat.ToList(), "id", "name", i.status.id); And here is my view - <%= Html.DropDownList("Status",Model.Statuses) %> I am getting an error when trying to run updatemodel in my controller. I then tried to individually set each object. It turns out that I am not getting a single int from the formvalue as I would expect to. Instead, I am getting a value like "5,10,2,3". I think this is coming from how I set up my selectlist, but I'm not exactly sure. Can anyone see an error in the way I am setting up this dd? Thanks for any help, and let me know if I can clarify anything.

• IOS SDK : first advices for beginners

  - by VdesmedT

  I too often answer the same kind of questions regarding basic topics like memory management, UITableView, Interface Orientation, MVC, etc... I understand very well that everyone starting with that SDK is too exited about getting its hand on it but a few reading would save them hours of debugging and the frustration that come along with the feeling that "We miss something here". I'd like experience users to share the few small articles, white papers, docs, book chapters that helps other save their time and avoid frustration. My first vote would be for : IOS Memory Management Guide View Controller Programming Guide Table View Guide And as a General recommendation, read the Overview section that come along with every class documention in the reference library, they contains most of what you need to know to avoid big traps !

• decode mysql query before returning it to view

  - by stormdrain

  I'm running a query to mysql that returns encrypted data. I'd like, if possible, to decode the results before sending it to the view. It seems like better form to handle the decoding in the controller (or even the model) rather than inside the view. I can't seem to wrap my head around how to do it, though. I was thinking I could iterate through the object, decodode it, and push it to another array that would be sent to the view. Problem with this is I won't know (and need to keep) the indexes of the query. So the query might return something like: [id] => 742 [client_id] => 000105 [last] => dNXcw6mQPaGQ4rXfgIGJMq1pZ1dYAim0 [first] => dDF7VoO37qdtYoYKfp1ena5mjBXXU0K3dDlcq1ssSvCgpOx75y0A== [middle] =>iXy6OWa48kCamViDZFv++K6okIkalC0am3OMPcBwK8sA== [phone] => eRY3zBhAw2H8tKE Any ideas?

• Rails: Ajax-enabled form without a model object

  - by Caffeine Coma

  I'm new to Rails and having a hard time figuring out how to create a form that submits over Ajax without having a corresponding model object. My use case is a simple form that collects an email address and sends it an email; there's nothing to be persisted, so no model. In cases where I do have a model, I've had success with form_for(@model, remote: true). I can't seem to find the right helper for the case where there is no model. I tried form_tag(named_path, remote: true) and that works, but does not use Ajax. Pointers to an example with an example with a proper controller, .html.erb and routes.rb would be really appreciated.
