I have 2 models, I'm working on, the user can have many of his favorite movies, and films can be multiple users like it, I decided to make the information stored in each of the users,
I tried to store moviesLiked array of movieid but every time I save, it throws an error, CastError: projected onto the ObjectId in path failure values' 1234 "moviesLiked",
I try to retrieve the movie object, and the movie. The id into the array, but it doesn't seem to work for me, and never delete it, I might have been doing something wrong, if someone told me that I should to which direction to go forward, because I am new about the mongoose,

Update: instead of id, although there is no work,
The router. The route ('/API/users/: userid/: movieid '), put (function (the req, res) {
Movie. FindById (the req. Params. Movieid, function (err, movies) {
User. FindByIdAndUpdate (
The req. Params. Userid,
