Django Free Hosting on Google App Engine

note: this post based on my experience hosting Django on Google App Engine. FREE on this article means I didn't have any billing every month, it's only personal site with not-too-much load or traffic.

Django Edit or Delete Permission

If you add Permission in Django via Meta or programatically [1], then you realized that you need to edit or even delete the permission.

How to edit or delete Permissions?

If you are really sure you want to edit or delete it with any risk, you can add Permission to your admin page. [2]

from django.contrib.auth.models import Permission

and of course you should change (or delete it) first on your model or code.

this example on SO is quite straigth forward and complete, about DRF with foreignkey.

ya, you also get django.test.Client information as a bonus. nice!

mostly my problem is about reverse relationship [1][2][3].

Django, web framework for perfectionists with deadlines

I used to use Jinja2 for templating, and it support Math calculation [1].

Now when try Django template, I can't calculate simple math (only add available via builtin filter), so I have to implement filter by myself, or using django-mathfilters [2].

What do you need is only install mathfilters with pip then add mathfilters to INSTALLED_APPS on your settings.
