Warn the user if we can't find target hooks for super scaffolding

[jagthedrummer]

The Scenario

Imagine you Super Scaffold a Project resource:

rails generate super_scaffold Project Team name:text_field

And then you open the Project model, and remove all of the target comments:

class Project < ApplicationRecord
  belongs_to :team

  validates :name, presence: true
end

And then you want to Super Scaffold a file_field onto Project.

rails generate super_scaffold:field Project documents:file_field{multiple}

Previously

Previously we would act like everything had gone according to plan, but in reality we wouldn't have updated the Project model with some important changes.

rails generate super_scaffold:field Project documents:file_field{multiple}
Adding new fields to Project with 'bin/rails generate migration add_documents_to_projects documents:attachments'

Updating './app/views/account/projects/_form.html.erb'.
Updating './app/views/account/projects/show.html.erb'.
Updating './app/views/account/projects/_index.html.erb'.
Replacing in './app/views/account/projects/_index.html.erb'.
Updating './app/views/account/projects/_project.html.erb'.
Updating './config/locales/en/projects.en.yml'.
Updating './config/locales/en/projects.en.yml'.
Updating './app/controllers/account/projects_controller.rb'.
Updating './app/controllers/account/projects_controller.rb'.
Updating './app/controllers/api/v1/projects_controller.rb'.
Updating './app/controllers/api/v1/projects_controller.rb'.
Updating './test/controllers/api/v1/projects_controller_test.rb'.
Updating './app/views/api/v1/projects/_project.json.jbuilder'.
Updating './test/controllers/api/v1/projects_controller_test.rb'.
Updating './app/models/project.rb'.
Updating './app/models/project.rb'.
Updating './app/models/project.rb'.
Updating './app/models/project.rb'.

You, as the developer, would think that everything worked, but then when you went to use the new attribute things wouldn't work quite right.

Now

Now we'll warn you that things did not go according to plan.

rails generate super_scaffold:field Project documents:file_field{multiple}
