You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: where_not.rb
    path of file: ./repos/rubocop-rails/lib/rubocop/cop/rails
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module RuboCop
  module Cop
    module Rails
      # Identifies places where manually co
    
        def extract_column_and_value(template_node, value_node)
          value =
            case template_node.value
            when NOT_EQ_ANONYMOUS_RE, NOT_IN_ANONYMOUS_RE
              value_node.source
            when NOT_EQ_NAMED_RE, NOT_IN_NAMED_RE
              return unless value_node.hash_type?

              pair = value_node.pairs.find { |p| p.key.value.to_sym == Regexp.last_match(2).to_sym }
              pair.value.source
            when IS_NOT_NULL_RE
              'nil'
            else
              return
            end
