sequelize.js - Sequelize error model is not associated -

-

i have 2 models: userauth , userfollow associate before sync. association userfollow has 2 foreign keys referencing user. did not use aliases when do:

userauth.findone({         where:{             id: "someid"         },         include: [{             model: userfollow         }],         logging: false     })

it throws error says: [error: user_follow not associated user_auth!]

i have class method "associate" in userfollow call before sync:

classmethods: {             associate: function(models) {                 // alter table user_follow                 // add foreign key (follower_id)                 // references user_auth(id)                 // on delete cascade                 // on update cascade                 userfollow.belongsto(models.user_auth, {                      ondelete: "cascade",                      onupdate: "cascade",                      foreignkey: 'follower_id',                      targetkey: 'id'                 });                  // alter table user_follow                 // add foreign key (follower_id)                 // references user_auth(id)                 // on delete cascade                 // on update cascade                 userfollow.belongsto(models.user_auth, {                      ondelete: "cascade",                      onupdate: "cascade",                      foreignkey: 'followee_id',                      targetkey: 'id'                 });             }         },
