How do I return the most sold item given a month and a year?
I need to be able to return the most sold item (and the quantity sold) given a month and a year. For example, if in a month: a) order 23: 2 cakes, 5 cupcakes b) order 21: 3 cupcakes Then I'd need it to return 5 cupcakes. How do I do this? This is the model: class Food(models.Model): name = models.CharField(max_length=100, unique=True) def __str__(self): return self.name class Order(models.Model): food = models.ManyToManyField('Food', related_name='order', blank=True) def __str__(self): return self.food Ths is the serializer: class OrderSerializer(serializers.ModelSerializer): class Meta: model = Order fields = '__all__' class FoodSerializer(serializers.ModelSerializer): class Meta: model = Food fields = '__all__' -
Django permissions for PasswordResetView
I am using django.contrib.auth.views to provide a reset email page to my users. The page to reset the password is generated as follow : path("user/reset_password/", auth_views.PasswordResetView.as_view(template_name="accounts/reset_password.html"), name="reset_password"), However my users can still access this page when logged in. How can I control the permissions to access the page since I do not have direct access to the view ? -

Django MySQL - correct way to connect
I have been using Django to connect to MySQL on my local computer and I have been using the following method to connect: run pip install mysqlclient and update the requirements.txt file appropriately. update the database connection in settings.py to something like this: 'ENGINE': 'django.db.backends.mysql', 'NAME': ......, 'USER': ......, A bit of a problem arose when I started to use a Dockerfile to try to run the Django app. When I build the Dockerfile and then run the django project, I start to get errors: django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module. Did you install mysqlclient? It seems to me that there are 2 potential solutions to this: 1 ) Adjust the Dockerfile so that it installs the software necessary for mysqlclient. This is actually a bit trickier than expected. Could you please make some recommendations for python:3.10.0a5-alpine3.12. 2 ) I was reading about mysql-connector-python. At present I have not got this to work. I installed it using pip, updated the requirements file and then changed the settings.py file to something like this: 'ENGINE': 'mysql.connector.django', 'NAME': ...., 'USER': ...., I have two area's of concern and I would really appreciate some help: 1 ) Which of these methods is the most appropriate … -
