SequelizeJS Order by renamed attribute - orm

Question

I came across an exception, cannot find solution anywhere. It looks like a bug of sequelizeJs.
Here is the question:
I have two model
module.exports = db.sequelize.define('user', {
// id is added automatically
createdAt: {
type: Sequelize.DATE,
field: 'created_at'
}
})
module.exports = db.sequelize.define('question', {
// id is added automatically
userId: {
type: Sequelize.BIGINT,
field: 'user_id'
}
})
User.hasMany(Question,{foreignKey:'userId',as:'questions'})
then I have a query:
models.User.findAll({
limit:limit,
order:[['createdAt','DESC']],
include : [{
{
model:models.Question,
as:"questions"
},]
})
I got an exception saying: "SequelizeDatabaseError: Unknown column 'user.created_at' in 'order clause'"
Here is the generated sql code:
SELECT ***** FROM (SELECT user.id, user.created_at AS createdAt FROM user AS user ORDER BY user.created_at DESC LIMIT 10) AS user LEFT OUTER JOIN question AS questions ON user.id = questions.user_id ORDER BY user.created_at DESC
It seems that order by is applied twice. At the second time, the 'created_at' has been renamed as 'createdAt'. That's why db complains 'cannot find user.created_at'.
My question is how to fix this problem so that I can run my query. I cannot find any available solution. And why Sequelize apply 'order by' twice? it looks like unnecessary.

Answer 1

This is an open issue it seems
See GitHub
However, you could try explicitly stating the attributes you want to query for on both models.

Answer 2

There is no issue with sequelize ,
Issue in below code : there one extra { inside the include block , remove that first
models.User.findAll({
limit:limit,
order:[['createdAt','DESC']],
include : [{
{
model:models.Question,
as:"questions"
},]
})
Query is 100% correct, I have executed the same way and its working fine from both side (sequelize and sql).
Issue you may have is :
your user table must have createdAt field named created_at
inside models.User.findAll() you might have used attributes and
forgot to add created_at
Try to run query inside your sql, and check for the error
SELECT *****
FROM (SELECT user.id, user.created_at AS createdAt FROM user AS user ORDER BY user.created_at DESC LIMIT 10)
AS user
LEFT OUTER JOIN question AS questions ON user.id = questions.user_id
ORDER BY user.created_at DESC
And you will figure it out whats wrong with the query
