Property 'belongsToMany' does not exist on type 'typeof ...

Thank you for creating this package!

Reproduction

I created a simple model but the .belongsToMany gives me the error Property 'belongsToMany' does not exist on type 'typeof ...

Steps to reproduce the behavior

1. Install piniaorm
2. Create a model (group.ts)

import { Model } from "pinia-orm";

import GroupMember from "./GroupMember";
import Member from "./Member";

export default class Group extends Model {
  static entity = "Group";

  static fields() {
    return {
      id: this.uid(),
      title: this.string(""),
      description: this.string(""),
      members: this.belongsToMany(Member, GroupMember, "group_id", "member_id"),
    };
  }
}

1. See that your editor (Webstorm in my case) says that belongsToMany does not exist.

Expected behavior

I would expect this.belongsToMany to exist and behave just like the original docs described it. https://vuex-orm.org/guide/model/relationships.html#many-to-many

Actual behavior

It says belongsToMany does not exist.

Additional information

If you didn’t implement belongsToMany it might be good to put this in the README.md

If you explain your goal I think we will find an solution 😃

As I understand you want to add a member to a group? If yes, you need the model group and member.

Solution 1: Add an belongsto fields to the member which points to the group model Solution 2: Add the fields hasMany to the group model and point to member

I finally got it to work like this:

const human = store.$repo(Human).new();
const group = store.$repo(Group).new();
const group2 = store.$repo(Group).new();
store.$repo(GroupMembership).fresh([
    { human_id: human.id, group_id: group.id },
    { human_id: human.id, group_id: group2.id }
]);

console.log(store.$repo(Human).withAll().first());
console.log(store.$repo(GroupMembership).withAll().first());

The only problem is that human.groups returns a list of GroupMembership and not groups. I’ll add a method in the model to handle that until the ManyToMany is implemented. By the way I am using vuex-orm next and not pinia yet.
