我想在 Rails 4 上使用 ApplicationRecord Cop。我已经添加了 'self.abstract_class = true' 。

class ApplicationRecord < ActiveRecord::Base
  self.abstract_class = true
end

这个文件写成'minimum_target_rails_version 5.0'。

https://github.com/rubocop-hq/rubocop-rails/blob/master/lib/rubocop/cop/rails/application_record.rb

所以我像这样创建了custom_cop。

# frozen_string_literal: true

module CustomCops
  # @example
  #
  #  # good
  #  class Rails5Model < ApplicationRecord
  #    # ...
  #  end
  #
  #  # bad
  #  class Rails4Model < ActiveRecord::Base
  #    # ...
  #  end
  class MustApplicationRecord < RuboCop::Cop::Cop
    MSG = 'Models should subclass `ApplicationRecord`.'
    SUPERCLASS = 'ApplicationRecord'
    BASE_PATTERN = '(const (const nil? :ActiveRecord) :Base)'
    include RuboCop::Cop::EnforceSuperclass
    

    def autocorrect(node)
      lambda do |corrector|
        corrector.replace(node.source_range, self.class::SUPERCLASS)
      end
    end
  end
end

但是我在运行 rspec 时遇到了错误，就像这样。

Failure/Error:
         class MustApplicationRecord < RuboCop::Cop::Cop
           MSG = 'Models should subclass `ApplicationRecord`.'
           SUPERCLASS = 'ApplicationRecord'
           BASE_PATTERN = '(const (const nil? :ActiveRecord) :Base)'
           include RuboCop::Cop::EnforceSuperclass


           def autocorrect(node)
             lambda do |corrector|
               corrector.replace(node.source_range, self.class::SUPERCLASS)

NameError:
         uninitialized constant CustomCops::RuboCop

你知道如何解决这个错误，或者其他方法（比如覆盖 'minimum_target_rails_version 5.0' 到 'minimum_target_rails_version 4.0' ）？

版本

Rails 4.2.8
ruby 2.6.6
rubocop 0.80.1
RSpec 3.9
4

该错误告诉您RuboCop未定义。

require 'rubocop'在定义警察之前，您需要在某个地方。
