this is my HTML: <form method = "post" action = "form/index"> <input type = "text" name = "username" /> </form>
and the form_controller: class FormController < ApplicationController def index @username=params[:username] end end
what's wrong about this? it works with GET method. but the API shows that params() Returns both GET and POST \parameters in a single hash. there's the error message below
ActionController::InvalidAuthenticityToken in FormController#index
