Question

我有以下型号：

class Vendor < ApplicationRecord
  has_many :warehouse_ingredients
  has_many :warehouse_ingredient_logs
end


class WarehouseIngredient < ApplicationRecord
  belongs_to :vendor
end

class WarehouseIngredientLog < ApplicationRecord
  belongs_to :vendor
end

我想要WarehouseIngredient＆amp;的所有记录。 WarehouseIngredientLog表，其中vendor_id = 1？

以下是WarehouseIngredient

的数据

此表中的条目将随着成分被移除（删除行）或添加（添加新行）而增加或减少。此外，一种成分可能同时具有多个条目，具有不同的lot_numbers。

此表中的条目将包含所有数据记录，因此此处将记录以前表值的任何更改。

我想要的结果是获取供应商1成分1的数据，其中transaction_type = 0;

Rails加入并包含多个表
