Permanently redirect to another url in django

I have an application in django 1.5. I would like to do redirect from one address to another - permanently. That is, I want to get an effect in which I will redirect:
from:
domain.com/team/event-2019/01-03-2019/827
to:
domain.com/team/event/01-03-2019/827 - (without 2019)

Django TypeError on every page

I haven't touched the code on my app in weeks but i'm suddenly getting this exact same TypeError on every page, including Admin pages.
The last thing to happen was an update on a model to change a ForeignKey field, but I don't feel the two are related

Solved it by looking through some of my own context processors. I had one function that was returning None on a request (after changing an entry and having an empty queryset as a result).

Yes I'm using latest version of Pillow and easy_thumbnails.

I made a mistake, sorry. This is not context processors, but thumbnail processors. I just add:
THUMBNAIL_PROCESSORS = (
'easy_thumbnails.processors.colorspace',
'easy_thumbnails.processors.autocrop',
'easy_thumbnails.processors.filters',
'filer.thumbnail_processors.scale_and_crop_with_subject_location',
)
Now all working.

relation "account_emailaddress" does not exist - django error

I am following this tutorial to integrate social media login to my django project -
http://www.sarahhagstrom.com/2013/09/the-missing-django-allauth-tutorial/
However after completing all the steps, when I try to login using facebook, I get this error
relation "account_emailaddress" does not exist
I don't understand what has gone wrong as all the DB modifications ran properly without errors.
Thanks in advance for your valuable answers.

I figured out what the problem was. the allauth uses account app which doesn't support migrations as yet. Initially I had run
python manage.py migrate allauth.socialaccount
python manage.py migrate allauth.socialaccount.providers.facebook
Along with this we need to run the syncdb to complete the puzzle.

I think you added library providers after performing the first migration, this leaves pending migrations
run
python manage.py makemigrations allauth
and
python manage.py migrate allauth

Using a variable as a Model Lookup

I am passing in a variable to my view which is the name of the model to be queried against.
model_name = 'application'
assets = model_name.objects.all()
I get the error that unicode objects don't have objects properties, which makes sense as my debugger shows model_name = u'application' as expected (not as wanted).
I figure it has to do with *args and **kwargs (which I'm new to, but think I get) especially since elsewhere in my code I have:
role_set = ['primary_tech', 'primary_biz', 'backup_tech', 'backup_biz']
for role in role_set:
records_to_change = Item.objects.filter(**{role:old_owner})
which works fine. I tried every combination of * and ** I could think of, as well as wrapping it in a for model_name in [model_name] for consistency's sake, and everything gives me a syntax error. What am I missing?
