I have an issue with sequelize. Here is what I'm trying to do:
return pointsTransaction.findAndCountAll({
where:{
user_id: userId
},
limit: opts.limit,
offset: opts.offset,
include:[{
model:sequelize.models.pointsPendingtransaction
}]
});
The generated query looks like that:
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 would just need to add that line at the end of my query to make it work: WHERE "pointsPendingtransactions"."transaction_id" IS null
So my question is, how can I do that with sequelize? I tried many different ways but no one worked...
Try to do next
where: {
transaction_id: {
$eq: null
}
}
to generate IS NULL
return pointsTransaction.findAndCountAll({
where:{
user_id: userId
},
limit: opts.limit,
offset: opts.offset,
include:[{
model:sequelize.models.pointsPendingtransaction,
where: {
transaction_id: {
$eq: null
}
}
}]
});
If you are using Sequelize's symbol operators from Sequelize.Op then ...
return pointsTransaction.findAndCountAll({
where:{
user_id: userId
},
limit: opts.limit,
offset: opts.offset,
include:[{
model:sequelize.models.pointsPendingtransaction,
where: {
transaction_id: {
// "$eq" changes to "[Op.eq]"
[Op.eq]: null
}
}
}]
});
$eq
and [Op.eq]
are not needed tested as of Sequelize 6.14.0
It works without them, just as it does for other values, eg:
where: {
transaction_id: null
}
produces IS NULL
.
You do need the magic syntax for IS NOT NULL
however as usual, achieved with:
where: {
transaction_id: {
[Op.ne]: null
}
}
The where
inside include
part of answer is then the same as for other non null values, see eg: Sequelize find based on association
