ActiveRecord:：TicketController中的AssociationTypeMismatch#新建

我有两个模型和控制器，一个用于用户，一个用于票据

每个用户可以有多张票。每个管理员用户（由

Admin:true

表示）可以分配许多票证给他们

以下是我的联想：

class Ticket < ActiveRecord::Base
  belongs_to :sender, class_name: "User", foreign_key: "id", inverse_of: :sent_tickets
  belongs_to :admin, class_name: "User", foreign_key: "id", inverse_of: :assigned_tickets

  .
  .
  .

end

class User < ActiveRecord::Base

  .
  .
  .

  has_many :sent_tickets, class_name: "Ticket", foreign_key: "sender", inverse_of: :sender, dependent: :nullify
  has_many :assigned_tickets, class_name: "Ticket", foreign_key: "assigned", inverse_of: :admin, dependent: :nullify

  .
  .
  .

end

classticket

但是，每当我尝试运行

@ticket=user.sent\u tickets.build

（在运行Rails IRB中的

user=user.first

之后，我在TicketsController中得到

ActiveRecord:：AssociationTypeMismatch\new:user（#number）预期，得到Fixnum（#number）

---

有人能帮我吗？

修复了它。我将

发送者

和

分配

重命名为

发送者id

和

分配id

。然后我重新编写了我的关联：

class Ticket < ActiveRecord::Base
  belongs_to :assigned, class_name: "User"
  belongs_to :sender, class_name: "User"

  .
  .
  .

end

class User < ActiveRecord::Base

  .
  .
  .

  has_many :help_requests, foreign_key: "sender_id", class_name: "Ticket", dependent: :nullify
  has_many :sent_requests, through: :help_requests , source: :sender

  has_many :tickets, foreign_key: "assigned_id", dependent: :nullify
  has_many :assigned_tickets, through: :tickets, source: :assigned

  .
  .
  .

end

classticket
