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

This cop checks for the use of methods which skip validations which are listed in https://guides.rubyonrails.org/active_record_validations.html#skipping-validations
Methods may be ignored from this rule by configuring a Whitelist
.
Example:
# bad
Article.first.decrement!(:view_count)
DiscussionBoard.decrement_counter(:post_count, 5)
Article.first.increment!(:view_count)
DiscussionBoard.increment_counter(:post_count, 5)
person.toggle :active
product.touch
Billing.update_all("category = 'authorized', author = 'David'")
user.update_attribute(:website, 'example.com')
user.update_columns(last_request_at: Time.current)
Post.update_counters 5, comment_count: -1, action_count: 1
# good
user.update(website: 'example.com')
FileUtils.touch('file')
Example: Whitelist: ["touch"]
# bad
DiscussionBoard.decrement_counter(:post_count, 5)
DiscussionBoard.increment_counter(:post_count, 5)
person.toggle :active
# good
user.touch
