Active Record Validations 4 Strict Validations 严格校验

version: Rails 4.1

 

严格校验

 

你也可以指定校验为严格的，当对象无效时，抛出异常 ActiveModel::StrictValidationFailed。

 

class Person < ActiveRecord::Base

  validates :name, presence: { strict: true }

end

 

Person.new.valid?  # => ActiveModel::StrictValidationFailed: Name can't be blank

也可以把定制化的异常传入到 :strict 选项中。

 

class Person < ActiveRecord::Base

  validates :token, presence: true, uniqueness: true, strict: TokenGenerationException

end

 

Person.new.valid?  # => TokenGenerationException: Token can't be blank
