class RuboCop::Cop::Rails::HasManyOrHasOneDependent
This cop looks for `has_many` or `has_one` associations that don't specify a `:dependent` option. It doesn't register an offense if `:through` option was specified.
@example
# bad class User < ActiveRecord::Base has_many :comments has_one :avatar end # good class User < ActiveRecord::Base has_many :comments, dependent: :restrict_with_exception has_one :avatar, dependent: :destroy has_many :patients, through: :appointments end
