Tools in the django ecosystem for managing contact databases

[quenti...@gmail.com]

Hi,


This is a question regarding tools that might be available in the
django ecosystem meeting the rather simple requirements briefly
summarized below.


I am looking for a web-based solution that, at its core, would be able
to handle a contact database. With the following constraint: think of
the contacts as being partitioned among different groups (one per
country, in an international setting for example), each group being
managed by a privileged set of users. These "managers" would be able
to create contact records via CSV uploads (which as a side effect
would create user accounts for contacts), and interact with the
contacts (via mail or in-app messages). Contact groups should be
independent of one another, in that managers of one group do not have
access to the personal data of contact members belonging to other
groups.


Now I feel that this may be rather common problems, and whishing to
avoid reinventing to many wheels, would like to know if anyone could
provide useful pointers in the django ecosystem of applications
providing similar base functionalities.


Thanks a lot,
Quentin
