ruby - 如何关闭太高的圈复杂度

Question

我在模型中有一个 where 方法抛出 lint 错误。 model中的全部代码目前只是测试代码，后续会进行重构。所以我想暂时关闭这个 lint 错误。

更新:这是我遇到 lint 错误的方法

def self.where(start_date, end_date, customer_id, type, location, is_registered)
  filtered_data = if start_date && end_date
                     customers.select do |e|
                       e[:startDateTime].to_datetime >= start_date.to_datetime &&
                         e[:endDateTime].to_datetime <= end_date.to_datetime
                     end
                   elsif start_date
                     customers.select {|e| e[:startDateTime].to_datetime >= start_date.to_datetime }
                   elsif end_date
                     customers.select {|e| e[:endDateTime].to_datetime <= end_date.to_datetime }
                   else
                     customers
                   end

  if !is_registered.nil? # is_registered is true or false
    filtered_data = customers.select { |e| e[:isRegistered].to_s == is_registered }
  end
  # Check if hash presents and check if the keys have valid values.
  if customer_id || type || location
    hash = { customerId: customer_id.to_i, type: type, location: location }
    # delete if type, location or customer_id is nil.
    hash = hash.delete_if { |_k, v| v.nil? || v == 0 }
    keys = hash.keys
    filtered_data = filtered_data.select { |h| h.select { |k| keys.include?(k) } == hash }
  else
    filtered_data
  end

  filtered_data.map do |slot|
    mock_customer(slot[:id], slot[:customerId], slot[:name], slot[:startDateTime],
               slot[:endDateTime], slot[:location], slot[:status])
  end
end

我尝试在模型中添加 # rubocop:disable Metrics/AbcSize 但没有帮助。

Answer 1

试试这个:

# rubocop:disable Metrics/CyclomaticComplexity
.... your method here
# rubocop:enable Metrics/CyclomaticComplexity

此外，如果您想为所有这些测试文件关闭 Rubocop(因为您要重构它们)，您可以尝试 this answer .
