自定义 Rails 验证未向输入添加“field_with_errors"包装器 [英] Custom Rails Validation not adding 'field_with_errors' wrapper to inputs

问题描述

我正在使用需要一些自定义验证的表单处理 Rails 4 站点.但是当验证标准失败并显示错误消息时，我正在检查的输入字段没有被赋予 field_with_errors 包装器.正在验证的所有其他字段都正确获取包装器，但它们的验证是对每个属性的简单存在检查.

I'm working on a Rails 4 site with a form that needed some custom validation. But when the validation criteria fails and the error message is shown, the input fields I'm checking aren't given the field_with_errors wrapper. All other fields being validated are getting the wrapper properly, but their validation is a simple presence check on each attribute.

如何在自定义验证中添加包装器?

How can I have the wrapper added in with my custom validation?

附加说明:如果可能的话，我只想显示一次我的错误消息 - 但要突出显示两个字段.

Additional notes: I'd like to only show my error message once, if possible - but highlight both fields.

在我的模型中:

validate :at_least_one_apply_method

def at_least_one_apply_method
  if [self.apply_url, self.application_instructions].reject(&:blank?).size == 0
    errors[:base] << ("Please provide at least one: Where to Apply or Applications Instructions.")
  end
end 

让我知道需要的任何其他信息.谢谢！

Let me know of any other information needed. Thank you!

推荐答案

您正在将自定义错误消息添加到 errors[:base].您需要将其添加到要包装的字段中，例如

You are adding the custom error message to errors[:base]. You need to add it to the field which you want to be wrapped e.g.

errors[:apply_url] << ("Please provide at least one: Where to Apply or Applications Instructions.")
errors[: application_instructions] << ("Please provide at least one: Where to Apply or Applications Instructions.")
