Pundit: Pundit::NotDefinedError: unable to find policy for class

[vmcilwain]

I am attempting to use pundit to check for an authorized user on a class in a controller. The current code I have is:

controllers/contact_mes_controller.rb
  def index
    authorize ContactMe
    @contact_mes = ContactMe.search(params.fetch(:q, "*"), page: params[:page], per_page: 10) #elasticsearch
  end

policies/contact_me_policy.rb

class ContactMePolicy < ApplicationPolicy
  def index?
    user.admin?
  end
end

The application policy is an untouched generated policy from the pundit gem.

When I run my feature specs for the index action, I get the following error:

 1) ContactMesController GET index sets @contact_mes
     Failure/Error: authorize ContactMe

     Pundit::NotDefinedError:
       unable to find policy `ContactMePolicy` for `ContactMe(id: integer, name: string, email: string, body: text, created_at: datetime, updated_at: date time)`

Unless I read the document wrong, I was under the impression that I was able to check authorization on a class when I didn't have a specific record to check against. Can anyone give me an idea of what I missed here?

Thanks

Something like this as suggested in the installation guide?

After generating your application policy, restart the Rails server so that Rails can pick up any classes in the new app/policies/ directory.

Hi,

I'm getting this error when I run my rspec tests. As far as I am aware there is nothing to restart.

Please check again your policies path and file access or post any differences that may be relevant.

OK. I will check what you have against what I have and see if I can figure out. I will respond once I do so.

Thanks for helping me with this.

I should have looked much much much more closely. app/policies/contact_me_policy.rb was actually app/policies/contact_me.policy.rb

I should have done a better job of debugging this. I thought I looked at all of the simple mistakes.

I apologize.
