Function MorphMap

morph map is merged by default

const map1 = {
  user: FedacoTestUser
};
const map2 = {
  post: FedacoTestPost
};
Relation.morphMap(map1);
Relation.morphMap(map2);

morph map is used for creating and fetching through relation

Relation.morphMap({
  user: FedacoTestUser,
  post: FedacoTestPost
});
const user = await FedacoTestUser.createQuery().create({
  email: 'linbolen@gradii.com'
});
await user.NewRelation('photos').create({
  name: 'Avatar 1'
});
await user.NewRelation('photos').create({
  name: 'Avatar 2'
});
const post = await user.NewRelation('posts').create({
  name: 'First Post'
});
await post.NewRelation('photos').create({
  name: 'Hero 1'
});
await post.NewRelation('photos').create({
  name: 'Hero 2'
});

morph map overwrites current map

const map1 = {
  user: FedacoTestUser
};
const map2 = {
  post: FedacoTestPost
};
Relation.morphMap(map1, false);
