• visual studio asp.net mvc, changing target framework

  - by mike

  Hello there Im have just changed the target framework for an asp.net mvc project from target framework 4 t 3.5, I keep getting this error when I try to debug, or go to any controller action 'HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly. ' Any ideas why I keep getting this error? as soon as I revert back to .net 4.0, everything is fine ps could be an issue with routing as the global.asax Application_Start() is not not hit hence route entries are not registered Thanks

• Where can I find the project templates for ASP.NET MVC 1.0?

  - by Jason

  I would like to edit the ASP.NET MVC templates for Visual Studio so that any new action or controller created has a specific piece of code within it by default. For instance, I'd like to replace the generated: public ActionResult MyAction() { return View(); } with a specific coding standard we prefer to use within in my team. eg: public ActionResult About() { try { DoStuff(); return View(); } catch(Exception) { HandleException(); } } I've looked through the filesystem, but I cannot find anything specific that relates to the ASP.NET mvc templates. Anyone know where they are?

• Paginator (Migration from Cake 1.3 to 2.0

  - by Christian Waschke

  i am struggling with the paginator in cakephp 2.0. While i am trying to migrate my application to 2.0 i cant find any solution to jump directly to the last page. In 1.3 it was quiet to do that from outside like this: echo $this->Html->link(__('Flights'), array('controller' => 'flights', 'action' => 'index','page' => 'last')); but this little trick putting 'page:last' in does not work anymore in 2.0. Of course there is a Paginator function called last, but this would only help if i would be already inside the app. My Problem is to access from an outside link directly the last page of the paginator. Thank you for reading, cdjw

• (Rails) How do I reference resources from non-restful views...?

  - by humble_coder

  Hi All, How do you ensure that your javascript includes get included properly for all files everywhere using a particular layout? Basically I have some non-restful actions that I've added. I haven't added any ROUTES for them, however, using normal text rendering works fine. It's when I start requiring different "swf" and "js" files (files which are properly placed in PUBLIC) that things get hairy. I start receiving "406 Not Acceptable" errors telling me that it's looking for the files in a subdirectory of the current controller. As it stands I'm in including the JS in "application" layout file. It works for the INDEX action, but doesn't seem to work for any of the non-restful actions. Thoughts?

• How do I create a dynamic method in PHP?

  - by sandelius

  I'm trying to extend my ActiveRecord class with some dynamic methods. I would like to be able to run this from my controller $user = User::find_by_username(param); $user = User::find_by_email(param); I've read a little about overloading and think that's the key. I'v got a static $_attributes in my AR class and I get the table name by pluralizing my model (User = users) in this case. How do I do this? All models extends the ActiveRecord class.

• Targeting row when responding with js rails

  - by berto77

  I have an application where a user can vote on reviews. They can vote up or down. Now when there's a listing of reviews, I have a problem targeting the review the user voted on. I'm using a respon_to block in my rails controller and responding with js. So for instance, I have a vote_up method, and a vote_up.js.erb template. in that template, I have the following: var id = $('article.comment').attr('id').split('_')[1]; alert("id: " + id); $('.votecomment_' + id).find('.score').html("<%= @review2.vote_total %>"); I'm just alerting the id. The problem is that the id always returns the value of the first review found on the page. How can I pass the context aka this, to javascript, so I can figure out which review to target?

Can someone point out what i'm missing?

• Kohana 3.2 useradmin routing issue

  - by user1789926

  I am new to kohana and am developing a simple application that is using the useradmin module from http://blog.mixu.net. I am having, what I think, an understanding problem. At present the action_index redirects to user/profile when a non admin user logs in. I want to go to a controller called home instead. I want to redirect to home/index.php I have tried simply changing the redirect and this does not work. I am suspecting I need to do something with routes to get me to home/index but I can not work out what I should be doing. I would really appreciate it if someone could steer me in the right direction here.

• Do I put ninject in my project that contains my service layer as well?

  - by chobo2

  Hi I have 3 project files(webui,framework that contains service layers and repos and unit tests). Most of my unit testing will be done in the service layer as this will contain all the business logic. So I will be mocking out the repo. In some cases I will query my a repo from my controller(say I just need all users in the database and I am not doing any business logic for it). So I am thinking that I need to have ninject used in my framework project. Where is the best place to put it so I can use them against my repos in my service layers?

• Get all Methods with a given return type

  - by Aren B

  Is this code wrong? It's just not returning anything: public IEnumerable<string> GetMethodsOfReturnType(Type cls, Type ret) { var methods = cls.GetMethods(BindingFlags.NonPublic); var retMethods = methods.Where(m => m.ReturnType.IsSubclassOf(ret)) .Select(m => m.Name); return retMethods; } It's returning an empty enumerator. Note: I'm calling it on a ASP.NET MVC Controller looking for ActionResults GetMethodsOfReturnType(typeof(ProductsController), typeof(ActionResult));

• [Cakephp] How to use Read()

  - by kwokwai

  Hi all, In a Controller, I got this: $this->Site1->post_id=$id; $this->set('posts', $this->Site1->read()); And when I replaced it by this line of code: $this-set('posts', $this-Site1-read('post_id', $id)); But the returned result is totally different. Is there any difference between them? Is it possible to make this two lines of code neat by re-writing it into one line of code? $this->Site1->post_id=$id; $this->set('posts', $this->Site1->read());

• My dropdownlist is not selecting an item as expected (MVC 1)

  - by Jen

  OK so I have 2 pages where this kind of behaviour is implemented. It works on one but doesn't work in another and I have no idea why. Despite the data containing a list of selectitems and one of them is selected the dropdown list is not displaying this selection (ie. it resets to the blank item). I don't know how to further debug this. In my page: <%= Html.DropDownList("CampusId", ViewData.Model.Campuses, new { @class = "large search_box" })%> In my controller. Campuses = AdminRepository .ListAll<Campus>(a => a.Description) .ToSelectListItem<Campus>(a => a.CampusId, a => a.Description, criteria.CampusId, true); I can see that campuses does have the correct list item marked as selected - so why when it is displayed on the page is it no longer marked as selected?! I can't see anything else obviously modifying the list. Thanks :)

  - by Mazonowicz

  I'm building an application that contains a bunch of projects that are at various stages, and I need to list the completed projects, or the projects that are at various other stages. So to list the completed projects, I name a scope; named_scope :current, :conditions => { :current_stage => "Completed" } and use; @projects = Project.current in my controller. But I how do I find all the projects at other stages? I thought it would involve != but I can't get that to work. Any pointers very much appreciated. Thanks a lot

• php calling classes functions in separate pages

  - by sys_debug

  I've worked with J2EE recently and like the idea of struts.xml where I can handle the redirection to pages based on return string from action classes. In PHP, in my new under-development site, I am trying to follow the MVC standards without an MVC framework used from the internet. So I create the controllers, models and views (empty now). The only thing I am really stuck at is when I submit the form in view (insert_product.php) then I will need to create another php page to handle the post data and pass them to controllers. Anyway of avoiding creating those pages and maybe having something like struts.xml? Even if I can post data directly to controller class, that would be good. Thanks,

• What is the difference between "render a view" and send the response using the Response's method "sendResponse()"?

  - by Green

  I've asked a question about what is "rendering a view". Got some answers: Rendering a view means showing up a View eg html part to user or browser. and So by rendering a view, the MVC framework has handled the data in the controller and done the backend work in the model, and then sends that data to the View to be output to the user. and render just means to emit. To print. To echo. To write to some source (probably stdout). but don't understand then the difference between rendering a view and using the Response class to send the output to the user using its sendResponse() method. If render a view means to echo the output to the user then why sendResponse() exists and vise versa? sendResponse() exactly sends headers and after headers outputs the body. They solve the same tasks but differently? What is the difference?

  I need to create certain number of UUId records (based on the selection of a drop down) and save them in the database. Now I am generating only one unique id. Can this be done in the model in this way? Or do I need to write a helper file for that? def generate_unique_token=(value) self.secret = Base64.encode64(UUIDTools::UUID.random_create)[0..8] end My controller: def create @secretcode = Secretcode.new(params[:secretcode]) @user = User.new(params[:user]) @secretcode.user_id = @user @secretcode.generate_unique_token = params[:secretcode][:secret] if @secretcode.valid? @secretcode.save redirect_to secretcodes_path else render 'new' end end My view page <%= form_for(@secretcode) do |f| %> <%= f.select(:secret, options_for_select([['1',1], ['10',10], ['20',20],['50',50]['100',100]])) %> <%= render 'layouts/error' %> <%=f.label :secret%> <%= f.hidden_field :user %> <%=f.submit :generate %> <% end %>

• CakePHP ACL use case(s)

  - by Jonathan

  I have got a simple web app in development, i want to establish a couple of user groups; Admin, Doctors & Patients. Each group would have their access restricted to particular controller actions rather than individual content. So for example, Doctors can view patient records (index & view actions), but cannot delete them. Usually i would create a groups model, and assign the various users to a group. And filter in the beforeFilter() method to determine if the user has access. But if ACL can do the job, why right the code, right? Thanks
