Authorization between services Django and NodeJs
I'm building an app using React on the frontend and Django and Nodejs on the backend. On the Django side I store the users and user authorization. Right now I'm using django-rest-knox to generate the user token, but the problem is that if I make a request to Nodejs service I cannot decrypt the token there. I must to make another request to Django service to verify the token. A solution would be to use JWT Token. But the JWT Token is not stored to database ( I cannot change the expiration type per individual token) I somebody here that faced the same problem like me or can give me an advice ? -

group by week for each year in django
I did find this comment from @HenryHeikkinen very usefull How to group by week in postgresql So I did correct my code. But still it is not ok. I did find some situation when it is not working correctly. When year is chaning during first week. My data model keeps some value for each day in year. I want to group data by week and compare several years. year 2018 is interesting 1.1.2018 is monday so first week of 2018 start at that day. last week of 2018 is 52 and starting at 24.12.2018 31.12.2018 is monday next week, but it is first week of 2019 and thats OK. But grouping by week, the result for that week (week 1 of year 2019) has week date = 31.12.2018, so extracting year info from that gives 2018 instead 2019 and thats make duplicity for week 1 of 2018. Year 2019 has that problem at beging and at the end. Week 1 of 2019 start at 31.12.2018 Week 1 of 2020 start at 30.12.2019 here is my django code which return week data self.dataday_set.annotate(ww=TruncWeek('date')) \ .values('ww') \ .annotate(consumption=Sum('consumption'), amount=Max('amount'), w=ExtractWeek('ww'), r=ExtractYear('ww')) \ .order_by('-ww') here is output section between 2017 and 2018, which … -

Running Django migrations within Docker container
Getting Django migrations to work within a Docker container has been tricky. Currently I spin up a MySQL container, then run ./manage.py makemigrations && ./manage.py migrate within wsgi-endpoint.sh to generate the SQL and apply it. I'm not fond of this workflow because there's no SQL paper trail to commit: any SQL created lives and dies within the container. I can't run makemigrations locally, though, because the database is containerized too. What's the best way to generate these files locally, or fetch them from the container? I realize I can copy them manually from container to host, but doing that after every database change is pretty rough. -

Heroku - Application error - Heroku crashes when DEBUG = False
I just figured out how to host my static files on Whitenoise and they are being hosted perfectly when DEBUG = False. I had to host them this way because in production I kept getting 500 errors because Heroku couldn't host my static files. This works fine now. I am now running into another problem, however. When DEBUG = False in settings.py now my whole Heroku app crashes and shows the page below. This is only when DEBUG = False. I originally thought it was allowed host but I set that value equal to '*' which should allow all just for testing and I still got the same problem.

How to redirect a user from django to react during email account activation

When I fill account registration form in react and submit it, the user is sent an email confirmation message. When I click on the activation link, how do I redirect the user to react since the email activation link is created in django and as such has django domain and not react domain.

<HaltServer 'Worker failed to boot.' 3> - Heroku Crash --- Worker failed to boot
Every now and then with my Django project launched on Heroku, it crashes. I know it is a change I am making somewhere but I cannot figure out what I am doing that is causing it.
