Set a session variable in devise on sign in

I'd like to set a session variable once a user signs in based on a certain field in the User table. I don't want to have to create a custom Devise controller if I don't have t开发者_开发技巧o. Is there a way? Or will I have to go the custom controller route?

There is a callback after_sign_in_path_for, you can add it in your ApplicationController

protected

def after_sign_in_path_for(resource)
  session[:domain_prefix] = current_user.domain_prefix
  user_path(resource)
end

Dont forget return the path in the last line of method, otherwise the callback will redirect the request to content of session[:domain_prefix]

How about this one:

The first resource I'd look at is http://github.com/plataformatec/devise/wiki/How-To:-Redirect-to-a-specific-page-on-successful-sign-in. Also, check out How to redirect to a specific page on successful sign up using rails devise gem? for some ideas.

You can do something like:

def after_sign_in_path_for(resource_or_scope)
  session[:account_type] = current_user.account_type

end

You can implement this method in your ApplicationController or in a custom RegistrationsController.
