Belongs_to presence in Rails 5 not working

Question

To my knowledge, the new default in Rails 5 requires belongs_to associations to be present. I made a model with this association, but the problem is I don\'t get pr

Answer 1

New Rails 5 applications come with a new initializer in

config/initializers/active_record_belongs_to_required_by_default.rb

If you upgraded a Rails 4 application or created your application with a beta version of Rails 5, then that file might be missing.

The configuration in that file enables the feature in question:

# Be sure to restart your server when you modify this file.

# Require `belongs_to` associations by default. This is a new Rails 5.0
# default, so it is introduced as a configuration option to ensure that apps
# made on earlier versions of Rails are not affected when upgrading.
Rails.application.config.active_record.belongs_to_required_by_default = true

Please check how belongs_to_required_by_default is configured in your application.
