Everything’s still OK:
11 assertions of 11 passed, 0 failed.
If those chained
.done
and
.fail
calls are bugging you—they bug me a little—you can
rewrite that as, eg:
var
deferred
=
$
.
post
(
urls
.
login
,
{
assertion
:
assertion
,
csrfmiddlewaretoken
:
token
}
);
deferred
.
done
(
function
() {
window
.
location
.
reload
(); })
deferred
.
fail
(
function
() {
navigator
.
id
.
logout
(); });
But async code is always a bit mind-bending. I find it just about readable as it is: “do a
post to urls.login with the assertion and csrf token, when it’s done, do a window reload,
or if it fails, do a navigator.id.logout”. You can read up on JavaScript deferreds, aka
“promises”,
here .We’re approaching the moment of truth: will our FTs get any further? First, we adjust
our
initialize
call:
lists/templates/base.html.
<script>
/*global $, Superlists, navigator */
$
(
document
).
ready
(
function
() {
var
user
=
"{{ user.email }}"
||
null
;
var
token
=
"{{ csrf_token }}"
;
var
urls
=
{
login
:
"TODO"
,
logout
:
"TODO"
,
};
Superlists
.
Accounts
.
initialize
(
navigator
,
user
,
token
,
urls
);
});
</script>
And we run the FT…
$
python3 manage.py test functional_tests.test_login
