我有一个模型订单。在索引中,我希望 current_user 仅查看包含他们的订单的索引。订单belongs_to :admin_user。AdminUser has_many:订单。我在我的应用程序中使用 activeadmin,如果这有影响的话。我收到此错误:
Couldn't find Order without an ID
给出错误的行是我的订单控制器中的第二行。(编辑了不必要的信息)
index do
@order = Order.where(admin_user_id: current_admin_user.id, order_id: resource.id)
column "ID" do |order|
link_to order.id, admin_order_path(order)
end
column "Proof" do |order|
image_tag order.proof_url(:proof).to_s
end
column "Name" do |order|
link_to order.name, admin_order_path(order)
end
column(:customer, :sortable => :customer_id)
column "Category", :order_category
column "Status", :order_status
column "Priority", :order_priority
column "Due Date", :end_date
default_actions
end
这是@jamesw 要求的我的订单模型
class Order < ActiveRecord::Base
attr_accessible :color_back, :color_front, :color_sleeve, :end_date, :name, :start_date, :whiteboard, :customer_id, :order_category_id, :order_type_id, :order_status_id, :order_priority_id, :print_location_id, :artwork, :proof, :line_items_attributes, :assignee_id, :admin_user_id
mount_uploader :artwork, ArtworkUploader
mount_uploader :proof, ProofUploader
has_many :line_items
belongs_to :assignee, :class_name => "AdminUser"
belongs_to :customer
belongs_to :order_category
belongs_to :order_type
belongs_to :order_status
belongs_to :order_priority
belongs_to :print_location
belongs_to :admin_user
accepts_nested_attributes_for :line_items, :allow_destroy => true
scope :owned_by, lambda { |user| includes(:assignee).where("admin_users.id = ?", user.id) }
def default_values
if new_record?
self.start_date ||= Date.today
self.number ||= (Order.maximum(:number) + 1 rescue 1)
end
end
end
