belongs_to presence validation: Ruby on Rails 5 Essential Training

In Ruby on Rails 5, the belongs_to relationship is not optional by default. When “belongs_to” is added to a model, it also adds a validation to ensure that the associated object is present. If it is not present then the record will be considered invalid and will not save. This behavior can be disabled if necessary by adding “:optional => true” to the model.
