Rails/devise app not working properly on Heroku due to new_user_registration_path

Question

Hope one of you can help me out on this one, since I've been breaking my head on it for a while.

I deployed my app to Heroku after trying it out on the cloud9 preview. The problem is that whenever I try to press the button to create a account for a paid subscription, I don't get linked to the page to fill in my credentials. However, on cloud9 this seems to be working fine.

I found the the sole difference between the two by hovering over the same buttons on the different platforms with my mouse.

On cloud9 I get: https://xxxxxxxx-xxxxx.xxxxxxx.xx/users/sign_up?plan=1

On Heroku I get: https://xxxxxxxx-xxxx-xxxxx.herokuapp.com/sign_up

So whenever I click the one on Heroku, I get my build-in flash message saying: Please select a membership plan to sign up!

To be more specific whereas the problem lies according to me, I think it's somewhere in the home.html.erb where the variable gets passed through. (added below)

So it seems that the routing isn't working correct on my Heroku, but I just can't figure out why. I've added my files below.

Hope someone can help me out on this one! Kind regards.

Answer 1

I fixed the problem, the thing you've mentioned about the database was right. The problem was that, for some reason, the db migration to Heroku was unsuccessful, without giving me any notice about it. After running:

Heroku run rails c
Plan.create(name: 'trial', price: 0)
Plan.create(name: 'pro', price: 75)

After running these commands the both plans were injected to the database of my Heroku app. My code seems to work perfectly fine now, altough I've changed the following piece of code according to your comment about hardcoding ID's

pages_controller.rb

class PagesController < ApplicationController
  def home
    if Plan.find_by name: 'trial'
      @trial_plan = 1
    end
    if Plan.find_by name: 'pro'
      @pro_plan = 2
    end
  end
end

Thanks for the heads up.
