Question

我有两个模型Event和User以及两个:through关联模型 - event_member和event_organizer。我创建了一些关联，并且在常规使用中它可以工作，但在事件和事件管理器页面的rails管理员中我有一个错误：

RailsAdmin中的ActiveRecord :: AssociationNotFoundError
协会名为＆＃39; event＆＃39;在EventOrganizer上找不到

当我更改关联时，我开始得到其他RailsAdmin错误

schema.rb：

#event_members
 t.bigint "member_id"
 t.bigint "event_id"
#event_organizers
 t.bigint "organizer_id"
 t.bigint "organized_event_id"

在模型中我有下一个代码：

事件

has_many :event_members
has_many :members, through: :event_members, source: :user

has_many :event_organizers
has_many :organizer, through: :event_organizers, source: :user

用户

has_many :event_members, foreign_key: :member_id
has_many :events, through: :event_members

has_many :event_organizers, foreign_key: :organizer_id
has_many :events, through: :event_organizers, source: :user

EventOrganizer

belongs_to :user, foreign_key: :organizer_id
belongs_to :event, foreign_key: :organized_event_id

EventMember

belongs_to :user, foreign_key: :member_id
belongs_to :event

Answer 1

has_many :events中有User的两个定义，应更改其名称以使其唯一且有意义。

Answer 2

这是错误范围的虚拟问题，它是：

has_many :ogranized_event, through: :event_organizers, source: :event

必须：

 has_many :event_organized, through: :event_organizers, source: :organized_event

两个has_many：通过与相同模型和RailsAdmin的关联
