Rails does not make any distinction between query string parameters and POST parameters, and both are available in the params hash in your controller:Ĭlass ClientsController < ApplicationController It's called POST data because it can only be sent as part of an HTTP POST request. This information usually comes from an HTML form which has been filled in by the user. The second type of parameter is usually referred to as POST data. The query string is everything after "?" in the URL. The first are parameters that are sent as part of the URL, called query string parameters. There are two kinds of parameters possible in a web application. You will probably want to access data sent in by the user or other parameters in your controller actions. It is a best practice to lower the visibility of methods which are not intended to be actions, like auxiliary methods or filters. Only public methods are callable as actions. This guide will 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. The Layouts & Rendering Guide explains this in more detail.ĪpplicationController inherits from ActionController::Base, which defines a number of helpful methods.
