我有模型:
class Order < ApplicationRecord
acts_as_paranoid
has_paper_trail
enum status: %i[created in_process]
has_many :order_containers
has_many :line_items
end
class LineItem < ApplicationRecord
acts_as_paranoid
has_paper_trail
enum status: %i[in_process collected]
belongs_to :order
belongs_to :variant
end
class Variant < ApplicationRecord
acts_as_paranoid
has_paper_trail
has_many :line_items
belongs_to :product
validates :barcode, presence: true
end
class Product < ApplicationRecord
acts_as_paranoid
has_paper_trail
belongs_to :isles, required: false
has_many :variants
validates :name, :volume, :sku, :price, presence: true
end
class Isle < ApplicationRecord
acts_as_paranoid
has_paper_trail
has_many :products
validates :name, presence: true
end
我只需要输出产品属于特定岛屿的订单.例如，如果订单中没有属于我需要的岛屿的产品，则不需要显示此订单及其产品.如果订单中有属于特定岛屿的产品，例如(isle.id 1)，则需要撤回此类订单，并撤回属于该部门的产品
我试着这样做:
@products = Order.includes([:line_items, :variants, :products, :isles]).where('products.isle_id = isle.id').references(:orders)
但我有个错误:
ailure/Error: return { "#{root_name}": [] } if records.blank?
ActiveRecord::StatementInvalid:
PG::UndefinedTable: ERROR: missing FROM-clause entry for table "products"
LINE 1: ..."orders" WHERE "orders"."deleted_at" IS NULL AND (products.i...
如果我设计得不好，我很抱歉，我是一个新手开发人员，这是我的第一个任务)
