如何处理ruby on rails 6中的验证错误?

Question

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"
]
}

}

，但我想要这样的:

{
"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

您可以覆盖默认的活动记录翻译: 

---
en:
activerecord:
errors:
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
