Delete a token

Problem

You need to delete a token from the current database.

Solution

Use the function:Delete[] function:

client.query(
  q.Delete(q.Ref(q.Tokens(), '1'))
)
.then((ret) => console.log(ret))
.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,
  err.errors()[0].description,
))
{
  ref: Ref(Tokens(), "1"),
  ts: 1631739422930000,
  instance: Ref(Collection("users"), "1"),
  hashed_secret: '$2a$05$HgbE0YEse2i7.5F4a5MHm.wGDmk4C3kMrP7NJpP40GrO06DgP584q',
  data: { team: 'Marketing' }
}
result = client.query(
  q.delete(q.ref(q.tokens(), "1"))
)
print(result)
{'ref': Ref(id=1, collection=Ref(id=tokens)), 'ts': 1631739701090000, 'instance': Ref(id=1, collection=Ref(id=users, collection=Ref(id=collections))), 'hashed_secret': '$2a$05$HExlDNKKmJP69pnpzVmf1.nsTDOJ5FbgfwUv9z1CXg./nQBsT70ny', 'data': {'team': 'Marketing'}}
result, err := client.Query(
	f.Delete(f.Ref(f.Tokens(), "1")))

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)
}
map[data:map[team:Marketing] hashed_secret:$2a$05$a77WPbm2U.Ms6GSw6oNp5uOZMefME5e.hLQxIhsgh/h2ceKQpxS8W instance:{1 0xc000109a10 0xc000109a10 <nil>} ref:{1 0xc000109860 0xc000109860 <nil>} ts:1631739856660000]
try
{
    Value result = await client.Query(
        Delete(Ref(Tokens(), "1"))
    );
    Console.WriteLine(result);
}
catch (Exception e)
{
    Console.WriteLine($"ERROR: {e.Message}");
}

Delete(Ref(Tokens(), '1'))
{

Discussion

Once a key has been deleted, any client still using the key’s secret can no longer execute queries.
