Rename a collection

Problem

You need to rename a collection within the current database.

Solution

Use the Update function:

client.query(
  q.Update(
    q.Collection('huts'),
    { name: 'dilapidated_huts' },
  )
)
.then((ret) => console.log(ret))
.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,
  err.errors()[0].description,
))
{
  ref: Collection("dilapidated_huts"),
  ts: 1622573895370000,
  history_days: 30,
  name: 'dilapidated_huts'
}
result = client.query(
  q.update(
    q.collection("huts"),
    { "name": "dilapidated_huts" }
  )
)
print(result)
{'ref': Ref(id=dilapidated_huts, collection=Ref(id=collections)), 'ts': 1622573900340000, 'history_days': 30, 'name': 'dilapidated_huts'}
result, err := client.Query(
	f.Update(
		f.Collection("huts"),
		f.Obj{"name": "dilapidated_huts"},
	))

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)
}
map[history_days:30 name:dilapidated_huts ref:{dilapidated_huts 0xc000109920 0xc000109920 <nil>} ts:1622573818060000]
try
{
    Value result = await client.Query(
        Update(
            Collection("huts"),
            Obj("name", "dilapidated_huts")
        )
    );
    Console.WriteLine(result);
}
catch (Exception e)
{
    Console.WriteLine($"ERROR: {e.Message}");
}
ObjectV(ref: RefV(id = "dilapidated_huts", collection = RefV(id = "collections")),ts: LongV(1622573797800000),history_days: LongV(30),name: StringV(dilapidated_huts))
Update(
  Collection('huts'),
  { name: 'dilapidated_huts' },
)
{
  ref: Collection("dilapidated_huts"),
  ts: 1624310573640000,
  history_days: 30,
  name: 'dilapidated_huts'
}
