has many post
s:
In your configuration you would have:
typescript
{
...
models: {
users: {
schema: '++id, email, createdAt, updatedAt',
properties: ['id', 'email', 'password'],
primaryKey: 'id',
relationships: {
posts: [HasMany, 'posts', 'user_id'],
}
},
posts: {
schema: '++id, user_id, title, body',
properties: ['id', 'user_id', 'title', 'body'],
}
},
...

accessor on the user
model: user.posts
