I am trying to retreive data from data from django backend to react but keep getting TypeError: get() missing 1 required positional argument: 'pk'
I have two concerns here. I am trying to retrieve data from django which contains images and contents. My first concern is whether using "Content-Type": "application/json" is right.

Is it possible to use Django to parse locally stored files (csv for example) without uploading them?
I would like to develop a WebApp that parses locally stored data and allows users to create a sorted excel file. It would be amazing if I could somehow avoid the uploading of the files. Some users are worried because of the data, the files can get really big so I have to implement async processes and so on... Is something like that possible? -

Django extend `UserManager` instead of `BaseUserManager`
Django docs says to define a custom manager you have to extend the BaseUserManager and provide two additional methods. But after doing so, I realized that my custom manager is vary similar to the default UserManager. So, is there a problem with inheriting from that instead? Like this: from django.contrib.auth.models import UserManager class CustomUserManager(UserManager): """Custom user model manager with email as the unique identifier.""" def _create_user(self, email, password, **extra_fields): if not email: raise ValueError("The given email must be set") email = self.normalize_email(email) user = self.model(email=email, **extra_fields) user.set_password(password) user.save(using=self._db) return user I just overrode the _create_user method, because others were identical. -
ArrayField consisting of composite field type
I have modeled composite field using https://pypi.org/project/django-composite-field/ in my django model (A URL field + a Boolean Field). What I want is to store a number of those (maybe in a list) in my base 'User' model. But ArrayField using django.contrib.postgres.fields only support a single data type. What I want is a list of the object (URL + boolean) for every user. Further I want to add validations for the number of objects eg.(min 2 objects, max 6 objects). What is a good way to model this? Thanks. -
django-tenants: access tenant media files in script
I am running an app built with djang-tenants. The app asks the user (tenant) to upload some data. I want the data to be segregated in sub directories for each tenant. Acccording to the doc (https://django-tenants.readthedocs.io/en/latest/files.html), here is how media root is configured: settings.py MEDIA_ROOT = "/Users/murcielago/desktop/simulation_application/data" MULTITENANT_RELATIVE_MEDIA_ROOT = "%s" On the upload everything is great. Now, I can't find a way to retrieve the file being uploaded within the app. Basically I need the app to serve the file corresponding to which tenant is requesting it. Here is how I thought this would work: from django.conf import settings media_file_dir = settings.MULTITENANT_RELATIVE_MEDIA_ROOT df = pd.read_csv(media_file_dir+'/uploads/sample_orders_data.csv') but this does not work. I have made it work so far grabbing the tenant name from the url and passing it to the app using pickle but this is not right in terms of security and won't scale. Would someone has a clue on the best way to handle the lecture of tenant specific files? -

Render a template within def get_object instead of raise raise Http404("Does not exist") in class based view
In the get_object method of class views, can I direct the user to a template instead of returning the object if an if statement fails? Currently raise Http404("Some message.") works good but it doesn't look nice, I want to use my own template. I'm trying to do this but with templates: def get_object(self): product = Product.objects.get(slug=self.kwargs.get('slug')) if product.deleted == False: if product.out_of_stock == False: return product else: raise Http404("This product is sold out.") # return reverse("404-error", kwargs={"error": "sold-out"}) # return render(request, "custom_404.html", {"error": "sold_out"}) else: raise Http404("This product is no longer available.") # return reverse("404-error", kwargs={"error": "deleted"}) # return render(request, "custom_404.html", {"error": "deleted"}) My main goal is to just avoid getting the object. I know I can perform the if statement in the get_context_data method, however I wasn't sure for objects containing sensitive data if there would be any way for a user to access it once it's in the get_object, so I just wanted to avoid getting the object altogether if the condition fails and display a template to the user. -
Django extend base.html along with its context
I've passed a variable to base.html from my views.py file in a context. I've extended this base.html to another several templates. The variable is only visible in the base.html and not any other extended template. It does work if I pass the same context to each templates views.py file. As I extended the base, shouldn't it also extend the variable? Is there any other way to get this working, or am I missing something? -
