Question

I would like to create a profile after an user signs up for my site using Devise. So in User model, I add:
after_create :build_spec

def build_spec
  Spec.new(:user_id => :id)
end

I also have a views/layouts/_header.html.erb that has a link to Spec:

<%= link_to "Profile", spec_path(Spec.find_by_user_id(current_user.id)) %>

This creates trouble when an user just completed signup form and clicked sign up button. He will be directed to some page. At this moment, I think Spec object for this user has not been created, thus the link in the _header partial doesn’t work (nil object), and user got an error:

No route matches {:action=>"show", :controller=>"specs"}

(Obviously, I had SpecsController with action “show”)

My question is: How to I create Spec for signed-up user before he is redirected to the first page after the sign up (in order to make the link to Spec works)?

Comments and advices are much needed.

Answer 1

Override the after_sign_up action in the Devise RegistrationsController.

https://github.com/plataformatec/devise/wiki/How-To:-Redirect-to-a-specific-page-on-successful-sign-up-%28registration%29

Which would then look like this:

class RegistrationsController < Devise::RegistrationsController
protected

  def after_sign_up_path_for(resource)
    Spec.create(:user_id => resource.id)
    after_sign_in_path_for(resource)
  end
end

Then again, your method might work as well, if you just replaced Spec.new(:user_id => :id)
by Spec.create(:user_id => :id)
Spec.new just creates a new instance of Spec but does not actually save it.
