我的模型"combobox" has_many "comboboxselects"
,和"comboboxselects" belongs_to "combobox"
。“组合框”的 Activescaffold 在组合框选择列中显示数据,如"#<Comboboxselect:0x472d25c>"
. 如何从表“comboxselects”中显示“答案”列?
楷模:
class Combobox < ActiveRecord::Base
has_many :comboboxselects
end
class Comboboxselect < ActiveRecord::Base
belongs_to :combobox
end
架构:
create_table "comboboxes", :force => true do |t|
t.string "question"
t.datetime "created_at"
t.datetime "updated_at"
end
create_table "comboboxselects", :force => true do |t|
t.integer "combobox_id"
t.string "answer"
t.datetime "created_at"
t.datetime "updated_at"
end
输出:
class ComboboxesController < ApplicationController
active_scaffold :combobox do |config|
config.list.columns = [:id, :question]
config.columns = [:question, :comboboxselects]
end
end
class ComboboxselectsController < ApplicationController
active_scaffold :comboboxselect do |config|
config.list.columns = [:id, :combobox, :answer]
config.columns = [:answer]
end
end
