    has_many :block_relationships, class_name: 'Block', foreign_key: 'account_id', dependent: :destroy

This cop looks for has(one|many) and belongsto associations where ActiveRecord can't automatically determine the inverse association because of a scope or the options used. This can result in unnecessary queries in some circumstances. :inverse_of must be manually specified for associations to work in both ways, or set to false or nil to opt-out.

Example:

# good
class Blog < ApplicationRecord
  has_many :posts
end

class Post < ApplicationRecord
  belongs_to :blog
end

Example:

# bad
class Blog < ApplicationRecord
  has_many :posts, -> { order(published_at: :desc) }
end

class Post < ApplicationRecord
  belongs_to :blog
end

# good
class Blog < ApplicationRecord

  has_many :replies, foreign_key: 'in_reply_to_id', class_name: 'Status', inverse_of: :thread
Severity: Minor
Found in app/models/status.rb by rubocop

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

  def token_for_app(a)
Severity: Minor
Found in app/models/user.rb by rubocop

This cop checks method parameter names for how descriptive they are. It is highly configurable.

The MinNameLength config option takes an integer. It represents the minimum amount of characters the name must be. Its default is 3. The AllowNamesEndingInNumbers config option takes a boolean. When set to false, this cop will register offenses for names ending with numbers. Its default is false. The AllowedNames config option takes an array of whitelisted names that will never register an offense. The ForbiddenNames config option takes an array of blacklisted names that will always register an offense.

Example:

# bad
def bar(varOne, varTwo)
  varOne + varTwo
end

# With `AllowNamesEndingInNumbers` set to false
def foo(num1, num2)
  num1 * num2
end

# With `MinArgNameLength` set to number greater than 1
def baz(a, b, c)
  do_stuff(a, b, c)
end

# good
def bar(thud, fred)
  thud + fred
end

def foo(speed, distance)
  speed * distance
end

def baz(age_a, height_b, gender_c)
  do_stuff(age_a, height_b, gender_c)
end

This cop checks that methods specified in the filter's only or except options are explicitly defined in the class or module.

You can specify methods of superclass or methods added by mixins on the filter, but these confuse developers. If you specify methods where are defined on another classes or modules, you should define the filter in that class or module.
