Comment (by Dmitri-Sintsov):
I have "orthogonal" kwargs in urls.py request to views mapping throughout
the code with the same url regex key names: 'project_id', 'profile_id' .
Then I implemented my own context middleware which process_view() checks
for 'project_id' / 'profile_id' of current view kwargs. It also has the
whole "business logic" context class, which tries to load Project /
Profile models from DB by these PK's, then checks current user access
permissions to these model instances, performs additional steps when
necessary.
That saves a lot of repetitive boilerplate code in views where I get ready
loaded and already checked self.request.context with appropriate project
and /or user profile models, instead of loading them over and over. The
trouble is, that sometimes I need to access that self.request.context
instance from ModelForm.clean() method and these forms are used not only
in views and CBV's where it's easy to add self.request to instance of
ModelForm, but also in django.admin, including third-party nested inline
admin.
I will probably have to implement per thread request context storage as
you've suggested. Because anyway I use stable 1.8 LTS, not current working
master (nested inline admin module has some troubles with newer Django
versions).
