Good day,
I have been struggling with this issue for weeks, and I can't figure out
what I'm doing wrong.
I have a model with a FileField with a custom upload_to function. It seems
to work fine when I'm doing runserver.
Problems arise during my tests.
My assertion error fails:
AssertionError: 'Rev0_2020-06-09_L123_My_Document_63ExUTF.docx' !=
'Rev0_2020-06-09_L123_My_Document.docx'
- Rev0_2020-06-09_L123_My_Document_63ExUTF.docx
? --------
+ Rev0_2020-06-09_L123_My_Document.docx
You see, it keeps adding these extra random characters to the filename,
which is not at all in my upload_to function.
class DocumentTestCase(TestCase):
def create_document(self, **kwargs):
if 'file' not in kwargs:
kwargs['file'] = self.get_test_file()
return Document.objects.create(**kwargs)
def _create_file(self):
f = tempfile.NamedTemporaryFile(suffix=self.TEST_FILE_EXTENSION,
delete=False)
with open(f.name, mode='wb'):
f.write(b"NA")
return open(f.name, mode='rb')
TEST_FILE_EXTENSION = ".docx"
def setUp(self):
super().setUp()
settings.MEDIA_ROOT = MEDIA_ROOT
def get_test_file(self):
file = self._create_file()
return File(file, name=file.name)
def test_rename_file_after_upload(self):
d1 = self.create_document(title="My Document", number="L123")
title = d1.title.replace(" ", "_")
extension = Path(d1.file.path).suffix
new_name =
f"Rev{d1.revision}_{d1.revision_date}_{d1.number}_{title}{extension}"
self.assertEqual(Path(d1.file.name).name, new_name)
