Unit test crashes due to migration incompatibilities with Django 1.11

Two tasks:

Devel_0.11.x branch:

• Enforce the 1.9.0 version to avoid problems in Django 1.10.7

Master branch:

• Fix the migration problems due to Django 1.11

As you explained, there are two possible solutions.

1. Forcing the use of django-debug-toolbar 1.9.0 works, if also Django==1.10.7 is used. This is the list of packets from pip freeze that make the migration script work. working_list_of_packages.txt

2. Fix the problem taking into account the two possible versions of Django and the django-debug-toolbar. In progress...

Okey, some follow up for task 2.

I tried to fix the migrations so we could use Django 1.11.5 and django-debug-toolbar 1.10.1.

I solved the 0066_subject.py with the following change (commit pending):

-        migrations.RunSQL('alter table web_studysubject_languages rename constraint web_subject_languages_subject_id_a5eb4f49_uniq to web_studysubject_languages_subject_id_a5eb4f49_uniq;'),
+        migrations.RunSQL('alter table web_studysubject_languages rename constraint web_subject_languages_subject_id_language_id_a5eb4f49_uniq to web_studysubject_languages_subject_id_language_id_a5eb4f49_uniq;'),

But then I got another issue with the following migration 0067_subject.py

The error now is this:

django.db.utils.ProgrammingError: relation "web_subject_default_written_communication_language_id_0bce1d22" already exists

And it rises after the first migration operation in line 37

This relation is an index in the table study_subject that I think, should be called web_stydysubject... instead of web_subject...

My experience with migrations is limited, but, would be enough to change the index name before creating the new model? Either way... I don’t know it tries to create a new index and why it conflicts if it’s going to be on a different table (web_subject).
