On March 22 (PST) we will be performing site maintenance on the database to improve performance, which requires taking down the website for a short period of time. The work is being done between 9pm-12am PST (3 hours), but we will only have a maximum of 1 hour of down time. We do not know exactly when within the 3 hours window we will be down. Thank you for your patience and understanding.

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.
