controller

问题 The setup: (using Asp.Net MVC 2 RC, Entity Framework, SQL Server, VS2008) My buddy and I are working on a project that will have different domains pointing at it. We want to get the domain (website) out of the Request and use that to drive data. This website data needs to be part of all the controllers. Ex. Data for domain1.website.com will be different than data for domain2.website.com, and those will be different than data for website2.com. The look of the site is the same for all these,

问题 I want to return a JSON array from a cakePHP controller. I effectively have a jquery click event which should send either a post, ajax or get call to the controller (specified with URL) and that controller should just return the array. This makes sense to me because I will not create a view file, I literally send the response to the controller and I can set the header, echo the json array and possibly just exit. My output only says "Array" on console, and does not echo out any parameters in

问题 Below is a screenshot of the POST request (using Firebug Net panel) I am sending to my ASP.NET MVC2 controller.

Could you please tell me what should the method signature look like on the server side? Or a

问题 In my controller I throw a 404 response after an If statement, something like that : if ($foo) { $this->getResponse()->setStatusCode(404); return; } Then, I would like to send some variables to my 404 page. In my mind, I want to do something like that : $this->getResponse()->setVariables(array('foo' => 'bar', 'baz' => 'bop')); $this->getResponse()->setStatusCode(404); return; It's not the good solution, so how I have to do that ? And after, how to get these variables in my 404 view ? Thank

问题 I know that if I have an url like XController/Action?id=1, and an action method void Action(int id) the id parameter will automatically be read from the query string. But how can I access the entire query string when I don't in advance know the name of all parameters. E.g: void Action(QueryStringCollection coll) { object id = coll["id"]; } Is it possible to do something like this? 回答1: Use Request.QueryString for this Request.QueryString.Keys gives you the name of all parameters 来源： https:/

问题 Assume for a moment that this form utilizes an imaginary Animal document object class from a ZooCollection that has only two properties ("name" and "color") in symfony2. I'm looking for a working simple stupid solution , to pre-fill the form fields with the given object auto-magically (eg. for updates ?).

问题 I'm trying to use JQuery's $.getJSON to access Model data from the Controller, and build a JSON object in the javascript to use as the user adds and removes items from a list. All JS is done in an external file. The hit to the server for the Model data is done only once after the page first loads so I can get the full list of options for the user to choose from. After that, the user can modify the list as much as he wants (and the JSON object is updated accordingly), and then save it off
