Association.save is not a function

[SrTreze]

Hi!

Apparently, my server crashes when I try to use a setter in a hasMany relationship.

I have this:

db.models.target_contents.extendsTo('multimedia', {
	title              : { type: 'text'        , required : true },
	picDataURL : { type: 'text'        },
	duration       : { type: 'integer'   , required : true },
	type	             : { type: 'boolean' , required : true },  // False -> audio, True -> video
	uploadDate  : { type: 'date'       , time        : true , required: true },
	lyrics            : { type: 'text'        }
})

db.define('gender', {
	gender : { type: 'text' , unique: true , required: true }
})

db.models.target_contents_multimedia.hasMany('gender', db.models.genders, {}, {autoFetch: true, mergeTable: "songGender", reverse: 'songs'})
db.models.target_contents_multimedia.hasOne('owner', db.models.target_account, { required: true }, {reverse: 'content'})

And I have a route that gets me every song from a owner, and for each, I want to set a gender. For that, I do this:

router.post('/songs/:artistID/:offset', function(req, res){
	req.models.target_contents_multimedia.find({owner_target_tId: req.params.artistID, type: false}).limit(10).offset(req.params.offset).each(function(song){
		song.setGender(9, function(err){
			if (err) console.log(err)
                        else res.send("ok")
		})
	})
})

Problem is, when he gets to the setter, it throws the following error:

TypeError: Association.save is not a function

I tried doing this because the getter was returning an empty array, even thou I entered an insert query into database.

Does anyone know why this happens? Or how to solve this? Thanks!

How are you calling .save ?
