rails_no_database_in_view

Prevent database access from the view.

Force loading all data from the controller by raising when the database is accessed from the view. This can help create effective database queries and help avoid SQL N+1 problems.

gem install rails_no_database_in_view

Enable in controller:

class ItemsController < ActionController::Base

  no_database_access_from_view! if Rails.env.development?

  ...

end

If the database is accessed from the view, a DatabaseAccessFromViewError will be raised.

You can't tell where in the view the exception came from. Yeah, that's pretty bad.

Don't use this. It probably doesn't work. :)
