Ruby on Rails - parameters in ruby on rails- ruby on rails tutorial - rails guides - rails tutorial - ruby rails
- Controllers have access to HTTP parameters (you might know them as ?name=foo in URLs, but Ruby on Rails handle different formats too!) and output different responses based on them.
- There isn't a way to distinguish between GET and POST parameters, but we shouldn't do that in any case.
class UsersController < ApplicationController
def index
respond_to do |format|
format.html do
if params[:name] == "john"
render html: "Hello John"
else
render html: "Hello someone"
end
end
end
end
