Rails Activeadmin - custom association select box
提问by alexs333
In my Rails application, I have the following model:
在我的 Rails 应用程序中，我有以下模型：
class Idea < ActiveRecord::Base
belongs_to :user
end
class User < ActiveRecord::Base
has_many :ideas
end
I am creating ActiveAdminCRUD for my Ideamodel with the custom form that looks something like that looks something like that:
我正在使用自定义表单为我的模型创建ActiveAdminCRUD Idea，该表单看起来像这样：
form do |f|
f.inputs do
f.input :member
f.input :description
end
end
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?
要求是具有成员协会内容的自定义文本，即"#{last_name}, #{first_name}". 是否可以自定义我的会员选择框来实现它？
Any help will be appreciated.
任何帮助将不胜感激。

Yes, that is possible. I assume you want to use a DropDown list box for membersto select a user from Usermodel.
是的，这是可能的。我假设您想使用下拉列表框members从User模型中选择用户。
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
