Create a token

Problem

You need to create a token in the current database.

Solution

Use the Login function:

client.query(
  q.Login(
    q.Ref(q.Collection('characters'), '181388642114077184'),
    { password: 'abracadabra' },
  )
)
.then((ret) => console.log(ret))
.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,
  err.errors()[0].description,
))
{
  ref: Ref(Tokens(), "309833836335727104"),
  ts: 1631739422080000,
  instance: Ref(Collection("characters"), "181388642114077184"),
  secret: 'fnEETMA7ijACAARMwDsk0AYAu4E51VmH1w-Xm7qk8T6eJcbinkI'
}
result = client.query(
  q.login(
    q.ref(q.collection("characters"), "181388642114077184"),
    {"password": "abracadabra"}
  )
)
print(result)
{'ref': Ref(id=309834127742337536, collection=Ref(id=tokens)), 'ts': 1631739699980000, 'instance': Ref(id=181388642114077184, collection=Ref(id=characters, collection=Ref(id=collections))), 'secret': 'fnEETMB_Y2ACAARMwH7g0AYAw183rIQzi0_4AnRBYTUf15JxUg8'}
result, err := client.Query(
	f.Login(
		f.Ref(f.Collection("characters"), "181388642114077184"),
		f.Obj{"password": "abracadabra"},
	))

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)

You can also create one directly, if the identity document does not have any credentials defined:

client.query(

The token’s secret is only ever shown once, in the response from the Login function. If you lose the secret, delete the token and create a new one.
