我有一个Editor模型与has_many :categorieshas_many :types,通过表categories_editorseditors_types如何在rails admin中显示关联的名称? (而不是id)

在管理界面中,我希望看到categories的名称。它适用于types(请参见下图),但是这两种关联的定义方式都是相同的。

enter image description here

class Editor < ApplicationRecord 
    has_many :categories_editors 
    has_many :categories, through: :categories_editors 
    has_many :editors_types 
    has_many :types, through: :editors_types 
end 

class Type < ApplicationRecord 
    has_many :editors_types 
    has_many :editors, through: :editors_types 
end 

class Category < ApplicationRecord 
    has_many :categories_editors 
    has_many :editors, through: :categories_editors 
end 

class CategoriesEditor < ApplicationRecord 
    belongs_to :editor 
    belongs_to :category 
end 

class EditorsType < ApplicationRecord 
    belongs_to :editor 
    belongs_to :type 
end 

是否有人有想法?

为了使您的对象的名称显示,你必须重命名列name

因此,我改变:

create_table "categories", force: :cascade do |t| 
    t.string "category" 
    t.datetime "created_at", null: false 
    t.datetime "updated_at", null: false 
    end 

到:

create_table "categories", force: :cascade do |t| 
    t.string "name" 
    t.datetime "created_at", null: false 
    t.datetime "updated_at", null: false 
    end
