How to retrieve dynamic value from Django settings.py in a Celery Task?
My Django rely on Celery and Celerybeat to spawn tasks. I have 3 systemd services/units: myapp.service (gunicorn daemon) celery-myapp.service (celery worker(s)) celerybeat-myapp.service (celerybeat daemon) I have an environment variable MY_SECRET defined in my main "myapp.service" service (systemd unit). I can't get this value from settings.py or directly environment variable in my tasks (tasks.py), but I can retrieve this value smoothly from my view (views.py) using settings.py or environment variable directly. Do I need to replicate environment variable MY_SECRET defined in myapp.service to celery-myapp.service and celerybeat-myapp.service so that I could grab this value from my Celery tasks? myapp.service [Unit] Description=My App After=network.target Wants=celery-myapp.service Wants=celerybeat-myapp.service [Service] User=myapp Group=nginx Environment=MY_SECRET=1234 WorkingDirectory=/opt/myproject/ ExecStart=/opt/myproject/env/bin/gunicorn --workers 3 --log-level debug --bind unix://opt/myproject/myapp.sock myaproject.wsgi:application [Install] WantedBy=multi-user.target Environment variable is referenced in my Django project 'settings.py' along with other settings I intended to use within the application: settings.py # Populated with environment variable defined by systemd unit MY_SECRET = os.environ.get('MY_SECRET') # Static value MY_URL= 'http://127.0.0.1' From my view I can get value defined as environment variable MY_SECRET from settings.py and directly from environment: views.py def my_view(request): from django.conf import settings as project_settings my_secret_env = os.environ.get('MY_SECRET') my_secret_setting = project_settings.MY_SECRET my_url_setting = project_settings.MY_URL return render(request,'mypage.html',{ 'my_secret_env': my_secret_env, 'my_secret_setting': my_secret_setting, 'my_url_setting': my_url_setting, … -
Perform calculations on data in backend in anticipation of API request
First up, I'm not looking for any code, but only guidance related to the workflow and technologies which can be used to address our specific problem. We have a system where we provide a visual query builder kind of interface. We have loads of data on which the user can apply this query. So the query can be something like all rows where x > 5 and y <2.5. While this is fairly easy to achieve, the problem we are facing is that the fields x and y are not pre-calculated fields and these relations can be defined by the user. For instance, the user can define a relationship like x = (a+b)-c^2 and then apply a filter on x. Since the value of x needs to be dynamically calculated, the query builder then takes significant amount of time to return the results. So I was wondering if we can implement some kind of prefetching and preprocessing such that the moment the user selects the field x, we calculate all the values for x in the backend. Since the user can take a few seconds to define the entire query, we'd have at least part of the calculation done by … -

Access basket/shipping address in django oscar pricing strategy
What would be the best practice to get the shipping address in a pricing strategy? Based on the country selected, I would like to apply tax, or not. I have an instance of CheckoutSessionData in my Selector, and the Selector inherits from CheckoutSessionMixin. But, CheckoutSessionMixin needs a basket for many operations, especially for getting a shipping address. And, the BasketMiddleware gets it's strategy first, and only then sets the basket on the current request. So, how to get the shipping address, before? Any best practices? -

django-allauth: override a user already existing
In my movies app, I allow anonymous users creating their own movie lists. This is done by means of retrieving the session_key parameter and saving it into the User model. So, I actually register anonymous users as users on the background, and their username is their id in this case. Now, when an authenticated anonymous user registers via Facebook or Google (registration is implemented by means of django-allauth), I want not to create a new User instance, but to update the existing user, so as to keep their movies_list intact, with their username changing from their id in the database to the actual username retrieved from Facebook. I have tried to play with the user_signed_up signal and to override DefaultAccountAdapter, but this yielded no results. Obviously, I just don't understand how this should work and need some conceptual advice on how to implement the desired scheme: update the existing User instance instead of creating a new one from Facebook or Google with django-allauth. -
What is the best way to handle different but similar models hierarchy in Django?
What is the deal: I'm crating a site where different types of objects will be evaluated, like restaurants, beautysalons, car services (and much more).

How do I make a signal run only if the user created is on a specific group in Django?

What am I missing in this Django model relationship
I have a custom user model, and a blog model. Here is the user model: class CustomUser(AbstractUser): pass email = models.EmailField(unique=True) first_name = models.CharField(max_length=20, default="", blank=True) and the blog model: class Blog(models.Model): pass user = models.ForeignKey(settings.AUTH_USER_MODEL, default=1, null=True, verbose_name=_('user'), related_name="%(class)s_blogs", on_delete=models.SET_NULL) blog_id = models.CharField(max_length=150, null=False, default=get_id, unique=True, editable=False) blog_title = models.CharField(max_length=150, null=False) My understanding is that I could use the related_name to get all blogs by a user. >>> from users.models import CustomerUser >>> user = CustomUser.objects.get(pk=1) >>> user.blog_blogs.all() <BlogQuerySet []> As you must have seen, this turns to always return but an empty queryset, even though there are blog entries by that user. So is it am not understanding here? Thank you. -
