我已经包含了给定的代码

@cod_order = Spree::Order.where(:cod_pay => true)

下一个代码

cod_order = Spree::Order.where(:cod_pay => true).accessible_by(current_ability, :index).unfulfilled.ransack(ransack_hash)
#  Ransack::Search<class: Spree::Order, base: Grouping <combinator: and>>
cod_order.result(distinct: true).page(params[:page]).per(params[:per_page] || Spree::Config[:orders_per_page])
  CACHE (0.0ms)  SELECT  DISTINCT "spree_orders".* FROM "spree_orders"  WHERE "spree_orders"."cod_pay" = 't' AND "spree_orders"."state" = 'complete' AND "spree_orders"."payment_state" IN ('paid', 'credit_owed') AND "spree_orders"."shipment_state" IN ('ready')  ORDER BY "spree_orders"."completed_at" DESC LIMIT 15 OFFSET 0
#<ActiveRecord::Relation []>

它给出了空白数组，请指导我为什么给出空白数组以及何时包含给定代码

@orders = @search.result(distinct: true).page(params[:page]).per(params[:per_page] || Spree::Config[:orders_per_page])
  Spree::Order Load (3.6ms)  SELECT  DISTINCT "spree_orders".* FROM "spree_orders"  WHERE "spree_orders"."state" = 'complete' AND "spree_orders"."payment_state" IN ('paid', 'credit_owed') AND "spree_orders"."shipment_state" IN ('ready')  ORDER BY "spree_orders"."completed_at" DESC LIMIT 15 OFFSET 0

我也试过了给定的代码

@cod_order = Spree::Order.where(["cod_pay = ? and payment_state = ?", true, "balance_due"]).accessible_by(current_ability, :index).unfulfilled.ransack(ransack_hash)
Ransack::Search<class: Spree::Order, base: Grouping <combinator: and>>
cod_order =  @cod_order.result(distinct: true).page(params[:page]).per(params[:per_page] || Spree::Config[:orders_per_page])
  Spree::Order Load (4.1ms)  SELECT  DISTINCT "spree_orders".* FROM "spree_orders"  WHERE (cod_pay = 't' and payment_state = 'balance_due') AND "spree_orders"."state" = 'complete' AND "spree_orders"."payment_state" IN ('paid', 'credit_owed') AND "spree_orders"."shipment_state" IN ('ready')  ORDER BY "spree_orders"."completed_at" DESC LIMIT 15 OFFSET 0
#<ActiveRecord::Relation []>

它总是返回空白数组。我想做一个像这样的查询

  

Spree :: Order Load（4.1ms）SELECT DISTINCT＆＃34; spree_orders＆＃34;。* FROM   ＆＃34; spree_orders＆＃34;在哪里＆＃34; spree_orders＆＃34;。＆＃34;州＆＃34; =＆＃39;完成＆＃39;和   ＆＃34; spree_orders＆＃34;。＆＃34; payment_state＆＃34; =＆＃39; balance_due＆＃39;和   ＆＃34; spree_orders＆＃34;。＆＃34; cod_pay＆＃34; =＆＃39; t＆＃39; AND＆＃34; spree_orders＆＃34;。＆＃34; shipment_state＆＃34;在   （＆＃39;准​​备好＆＃39;）ORDER BY＆＃34; spree_orders＆＃34;。＆＃34; completed_at＆＃34; DESC LIMIT 15 OFFSET   0

请指导如何进行此查询。提前谢谢。

1 个答案:

答案 0 :(得分：0)

您的查询均限于 shipment_state IN ('ready') ，但您的数据仅限shipment_state: "pending"。显然，结果必须是空的。

除此之外，你不需要DISTINCT，除非你的表中有完整的副本（不应该）。
