#30121: assertURLEqual() should coerce URLs built with reverse_lazy() ---------------------------------------------+------------------------ Reporter: Jon Dufresne | Owner: nobody Type: Bug | Status: new Component: Testing framework | Version: 2.2 Severity: Release blocker | Keywords: Triage Stage: Unreviewed | Has patch: 0 Needs documentation: 0 | Needs tests: 0 Patch needs improvement: 0 | Easy pickings: 0 UI/UX: 0 | ---------------------------------------------+------------------------ Calling `assertRedirects()` now uses the new `assertURLEqual()`. If a URL is built with `reverse_lazy()`, `assertRedirects()` now results in the exception:
{{{ Traceback (most recent call last): ... # My project calls assertRedirects() File "django/django/test/testcases.py", line 383, in assertRedirects msg_prefix + "Response redirected to '%s', expected '%s'" % (url, expected_url) File "django/django/test/testcases.py", line 404, in assertURLEqual normalize(url1), normalize(url2), File "django/django/test/testcases.py", line 399, in normalize scheme, netloc, path, params, query, fragment = urlparse(url) File "/usr/lib64/python3.7/urllib/parse.py", line 367, in urlparse url, scheme, _coerce_result = _coerce_args(url, scheme) File "/usr/lib64/python3.7/urllib/parse.py", line 123, in _coerce_args return _decode_args(args) + (_encode_result,) File "/usr/lib64/python3.7/urllib/parse.py", line 107, in _decode_args return tuple(x.decode(encoding, errors) if x else '' for x in args) File "/usr/lib64/python3.7/urllib/parse.py", line 107, in <genexpr> return tuple(x.decode(encoding, errors) if x else '' for x in args) AttributeError: '__proxy__' object has no attribute 'decode' }}} This does not happen with Django 2.1. Bisected to commit 24959e48d949a20be969f649ece3576dbc7ce422. A `reverse_lazy()` URL may be used as a class or module attribute to be reused by multiple tests methods. To solve this, the inner function in `assertURLequal()` can coerce the `url` argument using `str()`. https://github.com/django/django/blob/2.2a1/django/test/testcases.py#L394-L398 -- Ticket URL: <https://code.djangoproject.com/ticket/30121> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
