and what should I do if vulnerability don't have any related package ?

[ziadhany]

All these vulnerabilities don't have any related packages and it is old and not open source like you said @pombredanne
ignore.txt

[TG1999]

@ziadhany LGTM! please add some unit tests for same

[ziadhany]

@ziadhany LGTM! please add some unit tests for same

Done , @TG1999 have a look at the tests and Lmk if I need to add more tests

[ziadhany]

@pombredanne @TG1999 can you suggest a way to improve the performance ?

[tdruez]

@ziadhany For a data dump type of export, I would suggest simplifying the data structure by handling each model separately. Trying to load all relationships at once is likely to provide poor performance.

You can look into the Django build-in dumpdata management command at https://docs.djangoproject.com/en/4.2/ref/django-admin/#dumpdata

I tried to use django dumpdata but I don't think this could work in this task. so I tried to use .prefetch_related("vulnerabilities") to load the relationships but the script is still slow compared to dumpdata

[ziadhany]

Using prefetching makes performance worse. Maybe I'm using it in the wrong way.
there is a lot of query duplication and just 10 loops take more than 2129.20 ms without writing any file on the disk
