Ruby on Rails devise issues

Question

I have been trying to figure this out for way too long and i am hoping for some help here. I am new to Ruby and downloaded devise gem but when i try to run the sign up page it is giving me this error in my terminal:

Started GET "/users/sign_up" for 127.0.0.1 at 2013-09-11 17:52:28 -0700

I imagine this means i do not have a route for the sign up page. How do i set that up. I have looked online and tried almost everything and nothing seems to work.

Answer 1

I would first make sure Devise is set up properly, per the instructions here... https://github.com/plataformatec/devise

Specifically (after getting the Devise gem)...

rails generate devise:install

followed by...

rails generate devise MODEL

Where MODEL is often User.

After that your routes should just work assuming your links are correct. The sign up link alias is...

new_user_registration_path 

Your routes.rb should have something like the following in it if it's set up properly...

devise_for :users

Answer 2

In your routes.rb

devise_for :users

maybe try running

rails g devise User

Hopefully you have already run

rails g devise:install
