dataloader-sequelize: .paired missing on belongsToMany association

Hi,

Not sure whether my setup or association definition is off, but it seems to work fine without dataloader-sequelize.

I have the following “user/friends” association:

User.belongsToMany(User, {as: "friends", through: "Friends"});

This works:

const user = await User.findById(1);
const friends = await user.getFriends();

console.log(`You have ${friends.length} friend(s).`);

However, adding dataloader-sequelize to the mix:

dataloaderSequelize(User);
...
...

Yields the following error:

AssertionError: .paired missing on belongsToMany association. You need to set up both sides of the association.

I know, I have copied the existing tests and modified the sequelize models.

@kfrajtak https://github.com/kfrajtak Your PR should only add new tests, generally don’t modify existing tests unless a behaviour is incorrect and needs to change (which would result in a semver major)

ok i think i solved it with this.

user.friends = user.belongsToMany(models.user, {
      as: 'friends',
      through: 'friendship',
      foreignKey: 'userId',
      otherKey: 'friendId'
    })
    user.friendss = user.belongsToMany(models.user, {
      as: 'friendss',
      through: 'friendship',
      foreignKey: 'friendId',
      otherKey: 'userId'
    })
