Rails: place and break in front of the filter

Question

I want that before the filter, like "must_have_permission_to_write", when called, if the user does not have write permission, the message "you can not do this!" and come back.

The problem is that I get "can only render or redirect once per action", of course ... how can I stop execution in the front filter? thanks

Answer 1

I think the easiest answer is to add a redirect and return false to your method must_have_permission_to_write.

def must_have_permission_to_write
  unless current_user.has_permission?(something)
    redirect_to access_denied_path 
    return false
  end
end

Answer 3

Just add and returnfor example:

before_filter :must_have_permission_to_write

def must_have_permission_to_write
  redirect_to login_path and return unless current_user
end
