我是ruby on rails的新手,并且正在使用ruby on rails第4版进行项目。现在我正在更改活动管理员中的订单视图,但我收到错误。
ActiveAdmin.register Order do
permit_params :id, :order_completed, :approved
# changing the visual of view action, so admin user can able to see complete order details
show do |order|
attributes_table do
row :id # Order ID
row 'Name' params[:user].first_name # its not working, not showing the user first_name assiated with order id
# It should be user name. although user first_name is in users table and User model is availble.
row 'Adress' params[:user].address # its not working, not showing the user address assiated with order id
# It should be user address. although user first_name is in users table and User model is availble.
end
end
controller do
def show
order_id = Order.find(params[:id]).user_id
params[:user] = User.find(order_id)
show!
end
end
end
我的目标是显示订单相关用户的详细信息,如地址,姓名等。
订单表包含
- id
- user_id
- order_completed (boolean)
- approved
- order_status (string) [in process, done]
用户表格由
组成 - id
- first_name
- last_name
- address
- membership_id
答案 0 :(得分:0)
我会假设你已经建立了班级与班级之间的关系。和班级用户'在他们各自的模型中。 (belongs_to和has_many方法。如果您需要更多帮助,请告诉我。) 然后你必须在注册类时在Activeadmin 中声明这种关系,所以试试这个:
app/admin/order.rb:
ActiveAdmin.register Order do
permit_params :id, :order_completed, :approved
belongs_to :user # Declaring that order belongs to user here
# changing the visual of view action, so admin user can able to see complete order details
show do |order|
attributes_table do
row :id # Order ID
row 'Name' do
@order.user.first_name
end
row 'Address' do
@order.user.address
end
end
end
controller do
def show
@order = Order.find(params[:id])
show!
end
end
end`
