Question

我有一个Mongoid模型，验证根本不起作用。没有错误消息，没有问题，但我可以插入无效数据。

class Place
  include Mongoid::Document
  include Mongoid::Timestamps
  field :address, :type => String, :required => true
  field :headline, :type => String, :required => true
  validates :headline, :presence => true, :length => { :minimum => 10, :allow_blank => false }
  validates :address, :presence => true, :length => { :minimum => 5, :allow_blank => false }
  # ...
end

即使看起来它应该有效，但模型会保存而不会抛出错误（例如，值为nil或“abc”）。

我如何让他们工作？

Answer 1

对我而言，您的验证工作正常：

place = Place.create(:headline => nil, :address => nil)
puts place.persisted?  # false
puts place.valid?      # false
puts place.save        # false

create和save方法不会引发异常，save如果不成功则返回false（验证失败）。 save!方法确实引发了以下异常：

Validation failed - Headline can't be blank, Headline is too short (minimum is 10 characters), Address can't be blank, Address is too short (minimum is 5 characters). (Mongoid::Errors::Validations)

Mongoid验证不起作用
