Create many documents

Problem

You need to create many documents in a collection within the current database.

Solution

Use the Map function to iterate over an array, and use the Create function to create a new document for each item in the array:

Map(
  [
    { material: 'straw' },
    { material: 'sticks' },
    { material: 'bricks' }
  ],
  Lambda(
    "data",
    Create(
      Collection("dilapidated_huts"),
      { data: Var("data") }
    )
  )
)
[
  {
    ref: Ref(Collection("dilapidated_huts"), "329482154362798144"),
    ts: 1650477518490000,
    data: {
      material: "straw"
    }
  },
  {
    ref: Ref(Collection("dilapidated_huts"), "329482154363846720"),
    ts: 1650477518490000,
    data: {
      material: "sticks"
    }
  },
  {
    ref: Ref(Collection("dilapidated_huts"), "329482154363847744"),
    ts: 1650477518490000,
    data: {
      material: "bricks"
    }
  }
]
