我正在使用带有导轨(5.0.2)的virtus(1.0.5)。我将 Virtus 用于模型,因为它具有基于正在访问的页面的验证。
我的组织模型是
class Organization < ApplicationRecord
validates :name, presence: true
end
使用 virtus 创建的表单如下
class OrganizationProfileForm
include ActiveModel::Model
include Virtus.model
attribute :call_center_number, String, default: :org_call_center_number
validates :call_center_number, presence: true
def initialize(organization)
@organization = organization
end
private
def org_call_center_number
@organization.call_center_number
end
end
不幸的是,上面的代码不起作用
