Convert SQL query to Sequelize Query Format - mysql

Question

I'm new to Sequelize ORM. I would like to convert SQL query to Sequelize Query.
This is my SQL query, I want to convert this query to sequelize query:
SELECT * FROM `Posts` AS `Posts`
WHERE `Posts`.user_id IN
(SELECT `Follows`.receiver_id FROM `follows` AS `Follows`
WHERE `Follows`.user_id = user_id and `Follows`.status = "accept");
I have tried this but it does not return any data:
Posts
.findAll({ where: {
user_id: { [Op.in]: [{
include: [{
model: Follows,
attributes: ['receiver_id'],
where: {
user_id: user_id,
status:status
}
}]
}]
}
}})
.then(users => { res.send(users); })
After Executing above code it gives error in console
SELECT `event_id`, `user_id`, `event_message`, `e_imagepath`,
`createdAt`, `updatedAt`, `receiver_id`
FROM `Posts` AS `Posts`
WHERE `Posts`.`user_id` IN ('[object Object]');
I would like to convert SQL query to Sequelize Query.

Answer 1

You put your incude in the wrong position. Sequelize does not have a subquery feature as far I am aware of.
So you could do instead:
Posts
.findAll({ where: { user_id: user_id},
include: [{
model: Follows,
attributes: ['receiver_id'],
where: {
user_id: user_id,
status:status
}
}]
})
.then(users => { res.send(users); })
If the example above does not suits your need. You can also try to use a subquery by mixing raw SQL with Sequelize as the link below describes:

This works fine.
router.get('/posts', function(req, res)
{
const user_id = req.session.user_id;
const status = "accept";
Posts.findAndCountAll({include:[{ model: Likes},{ model: Comments},{ model: Users}],
where:{user_id:{[Op.in]:[sequelize.literal('SELECT `Follows`.receiver_id FROM `follows` AS `Follows` WHERE `Follows`.user_id=1 and `Follows`.status="accept')]}}
})
.then((postdata)=>
{
Users.findAll({where:{user_id:user_id}})
.then((userdata)=>
{
res.send(postdata.rows)
// res.render('home',{title:'home',items:postdata.rows,user:userdata});
})
.catch((err)=>
{
})
})
.catch((err)=>
{
})
});
