ResourceWarning: unclosed file

[erkib]

Python: 3.8.16
Django: 4.2.1
DRF: 3.14.0

When using ModelSerializer with FileField on Model and doing file upload with DRF, in the end of tests it shows:

...
OK
Destroying test database for alias 'default'...
sys:1: ResourceWarning: unclosed file <_io.BufferedReader name='/Users/xxx/SourceCode/private/xxx/_local/mediafiles/user_1/profile/xxx.png'>
ResourceWarning: Enable tracemalloc to get the object allocation traceback

@erkib Can you check in your code that the file has been closed after you have finished with upload. This warning is coming from the Cpython code. See here

I'm using the with-pattern as suggested by the django documentation and passing the file handle to upload model.
