how to handle devise's authenticate_user! with ajax call?

Question

I have a form with :remote => true which means it will be submitted through ajax.

In the controller, I have such code:

before_filter: authenticate_us         


        

Answer 1

It is quite funny but change in devise.rb http_authenticatable_on_xhr to false

config.http_authenticatable_on_xhr = false

did the trick for me... without overriding authenticate_user! method

note: I also added :js to navigational formats

config.navigational_formats = [:"*/*", "*/*", :html, :js]

Answer 2

You need do your own authenticate_user! action and in this action you can have the behaviour your want.

def authenticate_user!
  unless current_user
    render 'my_js'
  end
end
