How to add multiple items?

I know how to add one item: .put(cast({...})).
How to add multiple items?

Call put () every time or is there a better way?

const MyModel = types
   .model({
      members: types.map(Member),
   })
   .actions(self => ({
      ...
      const invites = data.map((item: any) => {
            ...
            return { ...item, ... }
       })
      // self.members.put(cast(invites)) << doesn't work for multiple items.
   })

Hi @thanksyouall!

You can use the merge method:

const MyModel = types
  .model({
    members: types.map(Member)
  })
  .actions((self) => ({
    someAction(members: any) {
      self.members.merge(members);
    }
  }));

const myModel = MyModel.create({
  members: {
    "1": {
      id: "1",
      name: "foo"
    },
    "2": {
      id: "2",
      name: "bar"
    }
  }
});

myModel.someAction({
  "3": { id: "3", name: "baz" },
  "4": { id: "4", name: "quz" }
});

Oh, thank you! It works.
I tried to use of the merge() method but I passed the wrong object format.
