#29, 23 Issue fixes, python dependencies

[pramodbontha]

29 , #23 issue fixes and added requirements.txt file for installing django dependencies at once

[pramodbontha]

Requirements.txt can used for directly installing all dependencies in one go python intstall -r requirements.txt will install all dependencies.

I need some help in understanding showing the explanations

I need to show explanation text for only wrong justifications for correct answer?. Will remove the text for correct justification.

Since all the justifications are wrong for a wrong answer Do I have to show explanation text to those justifications too?

Could you please help me understand this @tillmo

Thanks in advance

[tillmo]

please just show the explanation for one justification, namely for the justification that has been selected by the user. And do this only if the justification is wrong.

I wonder, how the requirements.txt got created. Is it generated? If so, how? I've seen it in other python apps and can conclude, that this does not work and is pure poison!

IMHO it is much much better, and works properly, to have a file like this, but manually maintained. I.e. if one needs a new python package/module, one should manually append it to the file and optionally a version number, if there is a real reason for it.

E.g. if I find . -type f -name "*.py" -exec grep ^from {} + in backend/lqserver/ I do not find any requirement for asgiref, certify, ... The only requirements I see, are some django and rest_framework modules. Therefore the file should look like

# NOTE: versions are those used in the next LTS release (20.04 alias focal)
django==2.2.11
djangorestframework==3.10.2
django-cors-headers==2.2.0
django-allauth==0.41.0'
django-nested-admin
django-rest-auth

Everything else is probably junk: let pip3 resolve the sub dependencies. They can, and will change! So IMHO unless you do not trust pip (which is ok ;-)) and really wanna manage each implicit dependency manually, specifying implicit dependencies is a big harm - you never know, when they change and whether they still have the same dependencies in the future, e.g. they may switch to use another implementation of XY ...
