Rails - Automatic validate has_many association

In Rails, you have a Question and Answer model.

question = Question.new
question.answers.build
question.valid?

This will return false because the associated answer is not valid. It’s most definitely not a bug because you are then asking “Rails, is this Question/Answer model and association I’ve created ready to be saved to the database?” and Rails say “No” in this case.

To ignore validate in associated model, you must put this code in Answer model: has_many: answers, validate: false
