Rails Activeadmin-自定义关联选择框 [英] Rails Activeadmin - custom association select box

问题描述

在我的Rails应用程序中，我有以下模型：

In my Rails application, I have the following model:

class Idea < ActiveRecord::Base
  belongs_to :user
end

class User < ActiveRecord::Base
  has_many :ideas
end

我正在创建 Idea 模型的href = http://www.activeadmin.info/> ActiveAdmin CRUD，其自定义形式类似于

I am creating ActiveAdmin CRUD for my Idea model with the custom form that looks something like that looks something like that:

form do |f|
  f.inputs do
    f.input :member
    f.input :description
  end
end

要求是拥有成员关联内容的自定义文本，即＃{last_name}，＃{first_name} 。

The requirement is to have the custom text for a content of the member association, i.e "#{last_name}, #{first_name}". Is it possible to customize my member select box to achieve it?

任何帮助将不胜感激。

推荐答案

是的，这是可能的。我假设您想使用成员的下拉列表框从 User 模型中选择一个用户。

Yes, that is possible. I assume you want to use a DropDown list box for members to select a user from User model.

form do |f|
  f.inputs do
    f.input :user_id, :label => 'Member', :as => :select, :collection => User.all.map{|u| ["#{u.last_name}, #{u.first_name}", u.id]}
    f.input :description
  end
end
