Defined in:
lib/rubocop/cop/rails/skips_model_validations.rb

Overview

This cop checks for the use of methods which skip validations which are listed in guides.rubyonrails.org/active_record_validations.html#skipping-validations

Methods may be ignored from this rule by configuring a ‘Whitelist`.

Examples:

# 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')

Whitelist: [“touch”]

# bad
DiscussionBoard.decrement_counter(:post_count, 5)
DiscussionBoard.increment_counter(:post_count, 5)
person.toggle :active

# good
user.touch
