Using count on a bookshelf relation

I have been trying to do a count like the answer in this SO question: http://stackoverflow.com/questions/32178130/bookshelf-js-relation-getting-count

Doing something like:

* countFollowing(userId) {
   return new User({id: userId}).follows().count();
 },

doesn’t return the expected number, but the total number of users in the database. On the other hand, and to prove that the follows() relation works, I can do something like this:

 * countFollowing(userId) {
    const followsJSON = yield this.getFollows(userId);
    return Object.keys(followsJSON).length;
 },

* getFollows(userId) {
    return new User({id: userId})
      .fetch({withRelated: 'follows'})
      .then(user => {
        return user.related('follows').toJSON();
      });
 },

which returns the expected number.

The definition of the relation is

follows() {
    return this.belongsToMany('User', 'Follows', 'follower_id', 'followed_id');
 },

Doing something like

* countFollowing(userId) {
    /* return new User({id: userId}).follows().count(); */
    /* const followsJSON = yield this.getFollows(userId);
     return Object.keys(followsJSON).length; */

    return yield new User({id: userId})
    .fetch()
    .then(user => {
      return user.follows().count();
    });
 },

also returns the total amount of users…

is it possible that this doesn’t work for counts because it is a belongsToMany instead of a hasMany, or am I doing something obviously wrong? Thanks!

done!

I think it’s relevant because it’s a bug that several people have stumbled upon.
