Question

下面有一个动态where clause排序的过滤器查询，

let ticketnotificationsWhere = {};
if (req.query.department) {
  ticketnotificationsWhere.department = req.query.department;
}
if (req.query.ticketid) {
  ticketnotificationsWhere.ticketid = req.query.ticketid;
}
let ticketWhere = {};
if (req.query.isactionable) {
  ticketWhere.isactionable = req.query.isactionable;
}
if (req.query.maintypeid) {
  ticketWhere.maintypeid = req.query.maintypeid;
}
if (req.query.typeid) {
  ticketWhere.typeid = req.query.typeid;
}
if (req.query.subtypeid) {
  ticketWhere.subtypeid = req.query.subtypeid;
}
let ticketdetailsWhere = {};
if (req.query.customerid) {
  ticketdetailsWhere.customerid = req.query.customerid;
}

return ticketdb.ticketnotifications.findAndCountAll({
  limit: req.query.pageSize,
  offset: req.query.page,
  where:ticketnotificationsWhere,
  attributes: ['id', 'ticketid', 'createdby', 'createddate', 'status'],
  include:[{
    model:ticketdb.tickets,
    required: true,
    where:ticketWhere,
    attributes: ['isactionable'],
    include:[{
      model:ticketdb.ticketdetails,
      required: true,
      where:ticketdetailsWhere,
      attributes: ['poid', 'productid', 'shippingreferenceno', 'customerid', 'issueqty']
    },
    {
      model:ticketdb.maintypemaster,
      attributes: [['name', 'maintypename']]
    },
    {
      model:ticketdb.typemaster,
      attributes: [['name', 'typename']]
    },
    {
      model:ticketdb.subtypemaster,
      attributes: [['name', 'subtypename']],
    },
    {
      model:ticketdb.ticketsource,
      attributes: ['sourcename']
    }]
  }]
})

问题在于，只有ticketnotifications的子句进入实际的SQL where子句，其余的条件tickets和ticketdetails进入JOIN的地方错误。甚至Limit子句也不会生成。生成的sql如下，

SELECT count("ticketnotifications"."id") AS "count" FROM
"ticketnotifications" AS "ticketnotifications" INNER JOIN "tickets" AS
"ticket" ON "ticketnotifications"."ticketid" = "ticket"."ticketid" AND
"ticket"."isactionable" = true AND "ticket"."maintypeid" = 18 AND
"ticket"."typeid" = 70 AND "ticket"."subtypeid" = 240 INNER JOIN
"ticketdetails" AS "ticket.ticketdetail" ON "ticket"."ticketid" =
"ticket.ticketdetail"."ticketid" LEFT OUTER JOIN "maintypemaster" AS
"ticket.maintypemaster" ON "ticket"."maintypeid" =
"ticket.maintypemaster"."maintypeid" LEFT OUTER JOIN "typemaster" AS
"ticket.typemaster" ON "ticket"."typeid" =
"ticket.typemaster"."typeid" LEFT OUTER JOIN "subtypemaster" AS
"ticket.subtypemaster" ON "ticket"."subtypeid" =
"ticket.subtypemaster"."subtypeid" LEFT OUTER JOIN "ticketsource" AS
"ticket.ticketsource" ON "ticket"."sourceid" =
"ticket.ticketsource"."sourceid" WHERE "ticketnotifications"."ticketid" = 123;

我期望的是

SELECT count("ticketnotifications"."id") AS "count" FROM
"ticketnotifications" AS "ticketnotifications" INNER JOIN "tickets" AS
"ticket" ON "ticketnotifications"."ticketid" = "ticket"."ticketid" INNER JOIN
"ticketdetails" AS "ticket.ticketdetail" ON "ticket"."ticketid" =
"ticket.ticketdetail"."ticketid" LEFT OUTER JOIN "maintypemaster" AS
"ticket.maintypemaster" ON "ticket"."maintypeid" =
"ticket.maintypemaster"."maintypeid" LEFT OUTER JOIN "typemaster" AS
"ticket.typemaster" ON "ticket"."typeid" =
"ticket.typemaster"."typeid" LEFT OUTER JOIN "subtypemaster" AS
"ticket.subtypemaster" ON "ticket"."subtypeid" =
"ticket.subtypemaster"."subtypeid" LEFT OUTER JOIN "ticketsource" AS
"ticket.ticketsource" ON "ticket"."sourceid" =
"ticket.ticketsource"."sourceid" WHERE "ticketnotifications"."ticketid" = 123 AND
    "ticket"."isactionable" = true AND "ticket"."maintypeid" = 18 AND
    "ticket"."typeid" = 70 AND "ticket"."subtypeid" = 240 
LIMIT 10 OFFSET 0;

我进行了很多搜索，得到了诸如在where中设置$$条件的解决方案，但这是针对一列的，我想根据过滤条件动态添加/设置where子句。知道我在做什么错吗？

您可以依次运营商：Operaters

因此，您的代码可以像这样：

 return ticketdb.ticketnotifications.findAndCountAll({
  limit: req.query.pageSize,
  offset: req.query.page,
  where: { [Op.and]: [{ticketId: req.query.ticketid}, {isactionable: req.query.isactionable},  {maintypeid: 18}]},
  include:[{
    model:ticketdb.tickets,
    required: true,
    where:ticketWhere,
    attributes: ['isactionable'],
    include:[{
      model:ticketdb.ticketdetails,
      required: true,
      where:ticketdetailsWhere,
    },
    {
      model:ticketdb.maintypemaster,
      attributes: [['name', 'maintypename']]
    },
    {
      model:ticketdb.typemaster,
      attributes: [['name', 'typename']]
    },
    {
      model:ticketdb.subtypemaster,
      attributes: [['name', 'subtypename']],
    },
    {
      model:ticketdb.ticketsource,
      attributes: ['sourcename']
    }]
  }]

希望它可以为您提供帮助。 让我们根据需要对其进行修改。
