javascript - Mongoose: Cannot call method 'push' of undefined, on nested Schema -


i set schema so:

var videoschema = new schema({     title: string,     url: string, //link video     rating: { type: number, default: 0},     description: string //a paragraph or 2 go along video });  var tutorialpageschema = new schema({     title: string, //ie peeking, clutching, etc.     tutorials: [videoschema] });  var categoryschema = new schema({     title: string, //intermediate, beginner, config, map knowledge, etc.     pages: [tutorialpageschema] });  exports.video = mongoose.model('video', videoschema); exports.tutorialpage = mongoose.model('tutorialpage', tutorialpageschema); exports.category = mongoose.model('category', categoryschema);

add document so:

var newpage = new models.tutorialpage({     title: req.query.page.title,     tutorials: [] }); parentcategory.pages.push(newpage);

in return, gives me nice "typeerror: cannot call method 'push' of undefined "

other times question asked, people didn't load schemas in correct order or conflated model schema when setting schema up, doesn't seem problem. gives?
