What Does a Controller Do Action Controller is the C in MVC. After the router has determined which controller to use for a request, the controller is responsible for making sense of the request and producing the appropriate output. Luckily, Action Controller does most of the groundwork for you and uses smart conventions to make this as straightforward as possible. For most conventional RESTful applications, the controller will receive the request this is invisible to you as the developer, fetch or save data from a model and use a view to create HTML output. If your controller needs to do things a little differently, thats not a problem, this is just the most common way for a controller to work. A controller can thus be thought of as a middleman between models and views. It makes the model data available to the view so it can display that data to the user, and it saves or updates user data to the model. For more details on the routing process, see Rails Routing from the Outside In. Controller Naming Convention. The naming convention of controllers in Rails favors pluralization of the last word in the controllers name, although it is not strictly required e. Application. Controller. For example, Clients. Controller is preferable to Client. Controller, Site. Admins. Controller is preferable to Site. Admin. Controller or Sites. Admins. Controller, and so on. Following this convention will allow you to use the default route generators e. URL and path helpers usage consistent throughout your application. See Layouts Rendering Guide for more details. The controller naming convention differs from the naming convention of models, which are expected to be named in singular form. Methods and Actions. A controller is a Ruby class which inherits from Application. Controller and has methods just like any other class. When your application receives a request, the routing will determine which controller and action to run, then Rails creates an instance of that controller and runs the method with the same name as the action. Clients. Controller lt Application. Controller. As an example, if a user goes to clientsnew in your application to add a new client, Rails will create an instance of Clients. Controller and call its new method. Note that the empty method from the example above would work just fine because Rails will by default render the new. The new method could make available to the view a client instance variable by creating a new Client. Client. new. The Layouts Rendering Guide explains this in more detail. Application. Controller inherits from Action. Controller Base, which defines a number of helpful methods. This guide will cover some of these, but if youre curious to see whats in there, you can see all of them in the API documentation or in the source itself. Only public methods are callable as actions. It is a best practice to lower the visibility of methods with private or protected which are not intended to be actions, like auxiliary methods or filters. Parameters. You will probably want to access data sent in by the user or other parameters in your controller actions. There are two kinds of parameters possible in a web application. The first are parameters that are sent as part of the URL, called query string parameters. The query string is everything after in the URL. The second type of parameter is usually referred to as POST data. This information usually comes from an HTML form which has been filled in by the user. Its called POST data because it can only be sent as part of an HTTP POST request. Rails does not make any distinction between query string parameters and POST parameters, and both are available in the params hash in your controller. Clients. Controller lt Application. Controller. This action uses query string parameters because it gets run. HTTP GET request, but this does not make any difference. The URL for. this action would look like this in order to list activated. Client. activated. Client. inactivated. This action uses POST parameters. They are most likely coming. HTML form which the user has submitted. The URL for. this RESTful request will be clients, and the data will be. Client. newparams client. This line overrides the default rendering behavior, which. Hash and Array Parameters. The params hash is not limited to one dimensional keys and values. It can contain nested arrays and hashes. To send an array of values, append an empty pair of square brackets to the key name. GET clients ids1 ids2 ids3. The actual URL in this example will be encoded as clients URLs. Most of the time you dont have to worry about this because the browser will encode it for you, and Rails will decode it automatically, but if you ever find yourself having to send those requests to the server manually you should keep this in mind. The value of params ids will now be 1, 2, 3. Note that parameter values are always strings Rails makes no attempt to guess or cast the type. Values such as nil or nil, nil,. See Security Guide. To send a hash, you include the key name inside the brackets. UTF 8 actionclients methodpost. Acme. lt input typetext nameclientphone value1. Carrot City. When this form is submitted, the value of params client will be name Acme, phone 1. Carrot City. Note the nested hash in params client address. The params object acts like a Hash, but lets you use symbols and strings interchangeably as keys. JSON parameters. If youre writing a web service application, you might find yourself more comfortable accepting parameters in JSON format. If the Content Type header of your request is set to applicationjson, Rails will automatically load your parameters into the params hash, which you can access as you would normally. So for example, if you are sending this JSON content. Carrot Street. Your controller will receive params company as name acme, address 1. Carrot Street. Also, if youve turned on config. JSON parameter. In this case, the parameters will be cloned and wrapped with a key chosen based on your controllers name. So the above JSON request can be written as. Carrot Street. And, assuming that youre sending the data to Companies. Controller, it would then be wrapped within the company key like this. Carrot Street, company name acme, address 1. Carrot Street. You can customize the name of the key or specific parameters you want to wrap by consulting the API documentation. Support for parsing XML parameters has been extracted into a gem named actionpack xmlparser. Routing Parameters. The params hash will always contain the controller and action keys, but you should use the methods controllername and actionname instead to access these values. Any other parameters defined by the routing, such as id, will also be available. As an example, consider a listing of clients where the list can show either active or inactive clients. We can add a route which captures the status parameter in a pretty URL. In this case, when a user opens the URL clientsactive, params status will be set to active. When this route is used, params foo will also be set to bar, as if it were passed in the query string. Your controller will also receive params action as index and params controller as clients.
