Serverside debug Django "Not Acceptable"
When calling an URL on my Django API it returns: [04/Sep/2021 08:14:47] WARNING [django.request:224] Not Acceptable: /api/calendar/test.ics Calling the same URL from PostMan (or curl) returns a simple iCal file so the URL is valid and returning. What I found was that the cause is the "Accept" headers sent by the client. The problem is that the request never actually hits my view so I cannot inspect request.META for the value of the received accept header. How can I discover, serverside, what headers were sent and what their values are? -
Django Rest Framework Permissions with firebase auth
I have backend with django-rest-framework, and frontend with react. And I have one endpoint which returns all users list. I want only admin be able to see all users list, so I put permission_classes = [IsAdminUser] in my view. I tested it with browsable api and everything works fine. Authentication system is with firebase in frontend, so every time when I send get request to server it returns authentication credentials were not provided because I don't use DRF endpoint to login, I use firebase login instead. So my question is how can I make only admin user see the data? -

Django form - what's the right form/template to create a many to many object inline
I have to two models Directors and JobProject. A JobProject can have multiple directors through a many-to-many relationship. Currently, when I create a new JobProject I choose from the directors I have saved who the director will be. However, I am trying understand how can I code a form/view for creating a JobProject where I can also create a director in-line (in case I don't have the director already saved in the DB). Ideally the users'flow would be: 1) Start entering a JobProject details. 2) If the director already exist in the DB, pick it. 3) If the director doesn't exist, allow users to enter the details of a new director object in-line 4) Users go ahead and finish entering JobProject details. 5) Users click save and the BE first save the new director and then save the new project with director pointing at the newly created director. I basically have 1,2,4,5 figured out but I can't understand how to do 3. Any help? These is my code right now. Model class Director(models.Model): ... name_surname = models.CharField(max_length=60) class JobProject(models.Model): ... director = models.ManyToManyField(Director, blank=True, ) Form class DirectorForm(forms.ModelForm): class Meta: model = Director fields = '__all__' exclude = ('id', 'owner', … -

If I do: python manage.py crontab add Terminal returns: sh: line 1: /usr/bin/crontab: No such file or directory (but it does recognise the details of the cronjob): /bin/sh: line 1: /usr/bin/crontab: No such file or directory adding cronjob: (325473fff5b0bfd8ec611f26efe10e43) -> ('*/1 * * * *', 'core.cron.my_scheduled_job') If I do: which crontab Terminal returns: which: no crontab in (/......../venv/bin:/app/bin:/usr/bin) It seems pretty clear this is a file routing problem, I just can't figure out a way to resolve, and there doesn't seem to be any similar cases I can find online.
