Sequelize where the ratio is zero

Question

I have a problem with sequelize. Here is what I am trying to do:

return pointsTransaction.findAndCountAll({
    where:{
        user_id: userId
    },
    limit: opts.limit,
    offset: opts.offset,
    include:[{
        model:sequelize.models.pointsPendingtransaction
    }]
});

The generated request looks like this:

SELECT "pointsTransaction".*,
"pointsPendingtransactions"."transaction_ptr_id" AS "pointsPendingtransactions.transactionPtrId",
"pointsPendingtransactions"."is_active" AS "pointsPendingtransactions.isActive",
"pointsPendingtransactions"."transaction_id" AS "pointsPendingtransactions.transaction_id" 
FROM (
SELECT "pointsTransaction"."id",
"pointsTransaction"."date_time" AS "dateTime",
"pointsTransaction"."details",
"pointsTransaction"."points",
"pointsTransaction"."user_id" 
FROM "points_transaction" AS "pointsTransaction" 
WHERE "pointsTransaction"."user_id" = 10002 LIMIT 1000
) AS "pointsTransaction" 
LEFT OUTER JOIN "points_pendingtransaction" AS "pointsPendingtransactions" 
ON "pointsTransaction"."id" = "pointsPendingtransactions"."transaction_id"

So, in SQL, I just need to add this line at the end of my query for it to work: WHERE "pointsPendingtransactions"."transaction_id" IS null

So my question is: how can I do this with sequelize? I tried many different ways, but no one worked ...

Answer 1

Try the next one.

        where: {
            transaction_id: {
              $eq: null
            }
        }

for generating IS NULL

return pointsTransaction.findAndCountAll({
    where:{
        user_id: userId
    },
    limit: opts.limit,
    offset: opts.offset,
    include:[{
        model:sequelize.models.pointsPendingtransaction,
        where: {
            transaction_id: {
              $eq: null
            }
        }
    }]
});

If you use the Sequelize character operators from Sequelize.Op, then ...

return pointsTransaction.findAndCountAll({
    where:{
        user_id: userId
    },
    limit: opts.limit,
    offset: opts.offset,
    include:[{
        model:sequelize.models.pointsPendingtransaction,
        where: {
            transaction_id: {
              // "$eq" changes to "[Op.eq]"
              [Op.eq]: null
            }
        }
    }]
});
