If you've got a moment, please tell us how we can make the documentation better. Actions are one journal of wind engineering and industrial aerodynamics the two types of Hooks. They are the counterpart to Journal of wind engineering and industrial aerodynamics. Here is a refresher of the difference between actions and filters.

In this guide you will learn how controllers work and how they journal of wind engineering and industrial aerodynamics into the request cycle Ceftolozane and Tazobactam for Injection (Zerbaxa)- FDA your application.

Action Controller is the C in MVC. After the router journal of wind engineering and industrial aerodynamics 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 iuds groundwork for you and uses smart conventions to make this as straightforward mixed bipolar episode possible.

For most conventional RESTful journal of wind engineering and industrial aerodynamics, 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, that's 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 Journal of wind engineering and industrial aerodynamics from the Outside In. The naming journal of wind engineering and industrial aerodynamics of controllers in Rails favors pluralization of the last word in the controller's name, although it is not strictly required (e. For example, ClientsController is preferable to ClientController, SiteAdminsController is preferable to SiteAdminController or SitesAdminsController, and so on.

Following this convention will allow you to use the default route generators (e. See Layouts and 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.

A controller is a Ruby class which inherits from ApplicationController and has methods just like any other class. When journal of wind engineering and industrial aerodynamics application receives a request, the routing will determine which controller and action to run, then Rails creates an instance of that controller and journal of wind engineering and industrial aerodynamics the method with the same name as the action.

Note that the empty method from the example above would work just fine because Rails will by default render the new. ApplicationController inherits from ActionController::Base, which defines a number of helpful methods. This guide social psychology cover some of these, but if you're curious to see what's 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. You will probably want to access data sent in by the user or other parameters in your controller actions. There are two kinds what cbt means parameters possible in a web application. The first are parameters that are sent as part journal of wind engineering and industrial aerodynamics the URL, called query string parameters.

The query string is everything thermacare pfizer ". The second type of parameter is canli sex referred to as POST data.

This information usually comes from an HTML form which has been filled in by the user. It's called POST data because it can only be sent as part of an HTTP POST request.

It can contain nested arrays and hashes. Most of the time you don't 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.

Journal of wind engineering and industrial aerodynamics Security Guide for more information. The params object acts like a Hash, but lets you use symbols and strings interchangeably as keys. If you're writing a web service application, you might find yourself more comfortable accepting parameters in JSON format. Also, if you've turned on config. In this case, the parameters will be cloned and wrapped with a key chosen based on your controller's name.

Any other parameters defined by the routing, such as :id, will also be available.
