我整个星期都在研究这个问题,尽管很多博客都在处理这个问题,比如this,但我遇到了错误:
undefined method `employeurs'...
让我们假设您有两种特定类型的用户,即雇员和prestataires。首先,您使用一般信息(姓名,电子邮件等)填写用户表单。然后,您可以在prestataire或employeur表单之间进行选择,这将保存用户表单并将您重定向到题字的第二部分。雇主和prestataires模型都与用户有属于关系。
使用下面的代码,我已经能够创建并保存用户表单,被重定向到雇主或prestataire表单,创建一个employeeur。然而,当我在employeeur控制器中使用@user.employeurs
时,就像在我的索引方法中一样,我收到一个错误:
undefined method `employeurs'
尽管我有嵌套路线:
resources :users do
resources :employeurs
resources :prestataires
end
用户模型:
class User < ActiveRecord::Base
has_one :prestataire
has_one :employeur
has_secure_password
end

belongs_to :user
has_many :projets, as: :projetable

由于我不明白这个错误可能来自何处,我可能忘记添加一些有用的代码部分。不要犹豫。提前谢谢。
答案 0 :(得分:0)
你混淆了路线和模型。嵌套路线对模型的组织没有任何影响。
resources :users do
resources :employeurs
resources :prestataires
end
这些路由具有将特定URL请求连接到控制器方法的效果。他们还设置了辅助方法,如users_path
等。
你宣布你的模型是这样的:
class User < ActiveRecord::Base
has_one :employeur
end
因此User
只有一个Employeur
,为什么您希望它有多个?{/ p>
我建议您重新考虑整个模型结构。我觉得Employeur
和Prestataire
实际上只是User
的子类型,而不是他们自己的类型。
答案 1 :(得分:0)
首先,对于has_one
关联,您应该使用 Singular Resource
resources :users do
resource :employeur #here
resource :prestataire #and here
end
其次,您应该将其称为@user.employeur
而不是@user.employeurs
,因为它与 has_one
的 users
关系但是不是 has_many
