sequelize - Where clause with associations

Question

In sequelize I have boards and users setup, with a many to many association as follows

User.hasMany(Board, {through: BoardUsers});
Board.hasMany(User, {through:BoardUsers});

Is there anyway that, using a where clause I can find users that belong to one of a list of boards. For example, lets says I have 3 boards and I would like to find the first 20 users (using the default sort order) who belong to either board 1 or 3. Is there a way to do this without executing separate finds for each board, then manually combining the results.

I would love to be able to do something like:

User.findAll({where:{board: [1,3]}});

but I can't seem to find a way to do this.

As far as I can tell the equivalent SQL would be something like:

SELECT * FROM `users` WHERE id IN (SELECT userID FROM boardusers WHERE boardId IN (1,3))

But I would love to be able to do it through the ORM.

Answer 1

While I'm not sure if you can do this directly, you can always query for Boards and eagerly fetch users.

Something along these lines:

Board.findAll({where: {id: [1,3]}}, { include: [ User ] })

Answer 2

相当迟到的反应，但只是有同样的问题，这就是我如何让它在Sequelize 3.24.0中工作（类似这样）;

User.findAll({ include: [{ model: Board, where: { $in: [1,3] }}] });
