NoMethodError in RegistrationsController#create undefined method `amount' for nil:NilClass

[AfolabiOlaoluwa]

I have an already existing jobs board application, and I have tried to implement this great work with it such that I can have stripe-membership on my http://localhost:3000/companies.

Note changes:

• Plan as you have it, is Subscription Plan in my application
• User as you have it, is Company in my application

When I click to SignUp for a plan and it renders a SignUp form, I get the following error:

Couldn't find SubscriptionPlan

Fix - I tried to change my Silver Plan id on my SubscriptionPlan table to "0" and it went through which is wrong but dont know what to do with it.

But new problem now is that, when I try to Sign Up for a Subscription Plan as a Company, it fails and give me the following error:

NoMethodError in RegistrationsController#create
undefined method `amount' for nil:NilClass

Yet, a company/user as you have it is created right in in my Company's table.

How do I fix all this? If this can be gemified and it intalls as an engine on any already existing model, it would be nice.

Going to before your fix, can you provide the full stack trace and any relevant methods that are called? What I'm trying to get at is figuring out if the error you're seeing for "Couldn't find SubscriptionPlan" is in a view, controller or model.

I actually created an issue not realizing at first that its the same issue here. I will post what I set:

Hey Guys/Gals, want to thank you for your detailed tutorials. I recently was introduced to Rails from a friend that was trying to get me to build this membership product in rails instead of the current platform I am using.

I've worked on this for the past week and problem after problem trying to get this to go live lol. I managed to overcome all of the issues except I keep getting an error when clicking on the signup link:

Seems to be an issue with 'data-payola-plan-type' => resource.plan.plan_class

[beardedguru]

So ran this in rails console:

CreatePlanService.new.call

and this fixed my issue @AfolabiOlaoluwa.

[AfolabiOlaoluwa]

@beardedguru can you hint what the fix (CreatePlanService.new.call) tackles or fixed really. Somewhat looks like the hack in Seed.rb file.
I will give this a try. But I hope it works well on production environment too.
Thanks for the fix.

[beardedguru]

@AfolabiOlaoluwa Actually looks like we may have over looked this in the instructions because I saw this in a stackoverflow post but did a quick search for it and it was written in the article here:
