Django → Django - Tutorial 047. How to do select_related and prefetch_related for an authenticated user
Imagine that for an authenticated user, when opening pages, some requests are constantly being executed, for example, an additional list of notifications is loaded, as well as his profile. And we use this information in templates, for example this way.
{% if user.is_authenticated %}
{{ user.profile.avatar }}
{{ user.notices.count }}
{% endif %}

Django → Django - Tutorial 046. Reset migrations in the project
In the process of developing a project on Django, we may encounter an unpleasant situation when some packages and modules were removed and, accordingly, models from these packages were no longer used. But at the same time, squash of application migrations does not allow removing these packages, since migrations have many circular dependencies. As a result, removing unnecessary packages becomes a rather difficult task. Since resolving such dependencies becomes a non-trivial task. For me, such an unpleasant package was Django CKEditor, which was present almost everywhere. As a result, this package due to migrations remained for quite a long time in the list of requirements.txt, although in fact it was not used on the site at all.
Django → Django - Tutorial 045. How to move model from one application to another
I would like to share one of the possible way for moving the data model from one application to another.
Immediately, I note that this version of the data model transfer is not 100% working and you may need additional manual editing of the tables to correctly set the Content Type. Since any such modifications are fraught with data loss for GenericForeignKey relationships.
In my case, GenericForeignKey was not used, so there was no such problem.

I propose to consider the process of installing and configuring a Django project on Mac OS X based on an existing project.
Some steps will be similar to those already performed in the Django setup article for Ubuntu .
