Sails.js Model: create 2 association to self failed

Question

I\'m pretty new on Nodejs and sails. I\'m implementing a server which is similiar to Twitter. In user model, there should be 2 fields: follower and following, and the 2 fiel

Answer 1

For such usage your model definition is incorrect, namely the via keywords. As per the waterline associations docs the via keyword references the other side of the association. So, for a follower the other side is following and vice-versa. In other words:

follower: {
  collection: 'user',
  via: 'following'
},
following:{
  collection: 'user',
  via: 'follower'
}
