Implement "flattening" when including fields in an association table

I am not sure how to title this issue, but let me explain.

Suppose we have two tables Person and Project plus a Role association connecting a person with one or more projects (in both directions). The Role association/table has a field called say RoleType.

I could set this up and query the db with for example:

Person.find({
   where: { id: 1 },
   include: [
      { model: Project, as: "projects", attributes: ["id", "name"], though: { attributes: "roleType" } }
   ]
})

which could produce something like

{
 name: "John Smith",
 id: 1,
 project: [ { id: 'a', name: 'Fix issue', role: { roleType: "manager" } }]
}

My issue is about the sub object role: { roleType: "manager" }. What I would like is a return similar to this:

{
 name: "John Smith",
 id: 1,
 project: [ { id: 'a', name: 'Fix issue', roleType: "manager" } ]
}

Namely I would like the roleType field to be available directly on each project item.

Is this possible to achieve? It would be nice to have it. Any suggestions for work arounds?

Sorry to ‘resurrect’ this issue, but may I ask if this is implemented in sequelize now, as I couldn’t find it in documentation?

Yes, you can add option raw : true so it becomes like:

Person.find({
   where: { id: 1 },
   include: [
      { model: Project, as: "projects", attributes: ["id", "name"], though: { attributes: "roleType" } }
   ],
   raw : true
})

And you can have a result like:

id : 1
name : 'Jhon'
...
Project.id : 4
Project.name : 'project name'
....
