ruby-on-rails - 如何处理 ruby​​ on rails 6 中的验证错误

问题描述

我是 ruby​​ 的新手，我正在研究一个错误结构，作为对我的 api 的响应。目前，验证错误返回如下：

{
"status": 400,
"message": "Profile update was unsuccessfull",
"errors": {
    "first_name": [
        "is too short (minimum is 3 characters)"
    ],
    "phone_number": [
        "Enter a valid us phone number"
    ]
}

}

但我想要类似的东西：

{
"status": 400,
"message": "Profile update was unsuccessfull",
"errors": {
    "first_name": "firstname "is too short (minimum is 3 characters)",
    "phone_number": "Enter a valid us phone number"
}

}

我的模型：

validates :first_name, :last_name, :state, :referral_method, presence: true, length: { minimum: 3, maximum: 25 }
validates :phone_number, format: { with: VALID_PHONE_REGEX, message: "Enter a valid us phone number" }, if: :phone_number_changed?

控制器：

# Handle validation errors
rescue_from ActiveRecord::RecordInvalid do |exception|
 messages = exception.record.errors.messages
 messages.map {|k,v| messages[k]=v[0] }
 @response = { status: Status.bad_request, message: Message.profile_not_updated, 
 errors:messages}
 json_response(@response, :bad_request)
end

      models:
        user:
          attributes:
            first_name:
              too_short: First name is too short (minimum is 3 characters)
            phone_number:
              too_short: Enter a valid us phone number
