Passing parameters in rails redirect_to

Question

How do we pass parameters in redirect_to in rails? I know we can pass id using this:

redirect_to :action => action_name,:id => 3

If I want to pass additional parameters like some form data how to achieve it?

EDIT:

For Ruby 2 syntax you have to update the snippet above to:

redirect_to action: action_name, id: 3

Answer 1

Just append them to the options:

redirect_to controller: 'thing', action: 'edit', id: 3, something: 'else'

Would yield /thing/3/edit?something=else
