Retrieve a single collection

Problem

You need to retrieve a the document that describes a collection from the current database.

Solution

Use the Get function:

client.query(
  q.Get(q.Collection('huts'))
)
.then((ret) => console.log(ret))
.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,
  err.errors()[0].description,
))
{
  ref: Collection("huts"),
  ts: 1622573894320000,
  history_days: 30,
  name: 'huts'
}
result = client.query(
  q.get(q.collection("huts"))
)
print(result)
{'ref': Ref(id=huts, collection=Ref(id=collections)), 'ts': 1622573899290000, 'history_days': 30, 'name': 'huts'}
result, err := client.Query(
	f.Get(f.Collection("huts")))

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)
}
map[history_days:30 name:huts ref:{huts 0xc000109830 0xc000109830 <nil>} ts:1622573814740000]
try
{
    Value result = await client.Query(
        Get(Collection("huts"))
    );
    Console.WriteLine(result);
}
catch (Exception e)
{
    Console.WriteLine($"ERROR: {e.Message}");
}
ObjectV(ref: RefV(id = "huts", collection = RefV(id = "collections")),ts: LongV(1622573782400000),history_days: LongV(30),name: StringV(huts))
Get(Collection('huts'))
{
  ref: Collection("huts"),
  ts: 1624310571870000,
  history_days: 30,
  name: 'huts'
}

Discussion

A collection document describes the container that contains documents; it is not the container itself.
