Overriding Devise Registration Create Method

Question

I want to specifically set a field when a user is created. I have

class RegistrationsController < Devise::RegistrationsController
  def create
    super
          


        

Answer 1

For future reference for anyone who finds this while searching for how to override devise methods, most of the Devise methods accept a block, so something like this should work as well:

class RegistrationsController < Devise::RegistrationsController
  def create
    super do
        resource.tag_list = params[:tags]
        resource.save
    end
  end
end

Answer 2

Instead of using super to invoke the Devise::RegistrationsController's create action, replace it with the actual code of Devise::RegistrationsController's create method

build_resource
resource.tag_list = params[:tags]   #******** here resource is user 
if resource.save
  if resource.active_for_authentication?
    set_flash_message :notice, :signed_up if is_navigational_format?
    sign_in(resource_name, resource)
    respond_with resource, :location => after_sign_up_path_for(resource)
  else
    set_flash_message :notice, :"signed_up_but_#{resource.inactive_message}" if is_navigational_format?
    expire_session_data_after_sign_in!
    respond_with resource, :location => after_inactive_sign_up_path_for(resource)
  end
else
  clean_up_passwords resource
  respond_with resource
end

Answer 3

If you don't want to rewrite the entire code of the create method, you can simply set the resource variable inside the protected method :build_resource of Devise::RegistrationsController, which is called before the resource is saved.

protected 

# Called before resource.save
def build_resource(hash=nil)
  super(hash)
  resource.tag_list = params[:tags]
end
