How do you get the max value for a foreign key value in models.py file?
This is my html file {% for member in member_list %} {% for batting in batting_list %} {% if member.id == batting.member.id %} {{ batting }} <br> {{ batting.match.id }} <br> {{ batting.runs }} <br> <hr> {% endif %} {% endfor %} {% endfor %} This is my models.py file class Member(models.Model): name = models.CharField(max_length=40, default='') def __str__(self): return str(self.name) class Batting(models.Model): member = models.ForeignKey(Member, on_delete=models.CASCADE, default='') runs = models.IntegerField(blank=True, null=True) match = models.ForeignKey(Match, on_delete=models.CASCADE, default='') def __str__(self): return str('{0} {1} scored {2} runs'.format(self.member, self.match.date, self.runs)) I am trying to figure out how I show the max runs for a member x in the html file.

The DAL function "select2" has already been registered
I see a weird bug in while I want to use autocomplete dropdown. I am using a django-autocomplete-light which loads values using ajax. It works perfectly on localhost but after deploying on AWS EC2 instance it raises the following error: autocomplete_light.min.js:1 The DAL function "select2" has already been registered. yl.registerFunction @ autocomplete_light.min.js:1 I have some doubts that this is something related to the jQuery file loading. after collectstatic order I have these files in static folder: admin app autocomplete_light ckeditor django_tinymce js tinymce vendor I guess there is a conflict in autocomplete_light new version( which probably loads min.js) and ckeditor. By the way, tinymce can be deleted as I am not using anymore(just for saying). Please let me know If you have some solution for this problem -
Use an external database in Django app on Heroku
I am trying to deploy a Django REST API on Heroku. Normally I wouldn't have any issues with this but for this app, I am using a legacy database that exists on AWS. Is it possible for me to continue to use this remote database after deploying Django to Heroku? I have the database credentials all set up in settings.py so I would assume that it should work but I am not sure. -
REST API with Django Admin
I am building an API-first app with the Django REST framework, so it has no html views at all and uses only token-based authentication. At the same time, I would like to make use of the Django admin interface, which is no problem, but I am worried about the performance costs as it depends on a lot of apps (sessions, standard auth, messages, csrf, etc.), that are not needed in the main app, but will run on every request. Is there a way to set admin-specific middlewares to run only on the admin interface? I know I can subclass them and raise MiddlewareNotUsed on all requests except ones going to the admin site, but maybe there is some build-in or well-known solution to this? -

How to stream video to more than one client using Django development server
I am trying to stream video to multiple browsers using opencv and django on a raspberry pi. In the code I share below, I am able to see my video stream on a different computer which is great, but when another computer tries to access the stream it just gets a blank screen. If I close the stream on the first computer, the second computer will now be able to access it.
