Making use of the token generated upon log in
I have coded the API to work with my web and also generate token upon login/register from the Postman request by using knox for the token. Now I want to make use of this token that is linked to the account that is logged in to get the username so I can know which account who make the request. But I am not sure on how to use this token.

Django / Models / Admin / Problem with the foreign key : __str__ returned non-string (type tuple)
I have already tried multiple solutions find on other topics but nothing works. I have a problem the foreign key in Django Admin. Impossible to see a records or add a new record. I have a table convertion_factor with no NULL values. see postgreSQL config This is my model : class convertion_factor(models.Model): foodID = models.ForeignKey('food_name', on_delete=models.CASCADE) measureID = models.ForeignKey('measure_name', on_delete=models.CASCADE) conversionFactorValue = models.FloatField() convFactorDateOfEntry = models.DateField(auto_now=False, auto_now_add=False) In order to views the data in Django Admin, you have to add def __str__(self): to the model. Ok let's do that : class convertion_factor(models.Model): foodID = models.ForeignKey('food_name', on_delete=models.CASCADE) measureID = models.ForeignKey('measure_name', on_delete=models.CASCADE) conversionFactorValue = models.FloatField() convFactorDateOfEntry = models.DateField(auto_now=False, auto_now_add=False) def __str__(self): return self.conversionFactorValue Now when I go to Django Admin and I click on the model convertion_factor I can see the table just fine but when I try to click on a record to edit it, I have this error : TypeError at /admin/kalo/convertion_factor/19505/change/ Exception Type: TypeError at /admin/kalo/convertion_factor/19505/change/ Exception Value: __str__ returned non-string (type float) I have the impression this is an error due to the foreign key because with my others models without a foreign key, everythings work just fine.

Django - Communicate with persistent process
We have a legacy C library that can be used to communicate with a custom local server, and we have written command-line and GUIs tools with it. Now we would like to create a web interface using the library so users can just use the tools via a web browser instead of needing to install them locally. I have experience with Django, and this seems mostly plausible. However, there is one big hang up. In order for the C library to communicate with the local server, it must open up a per-instance connection for each user before transmitting data (and then closing the connection when the session is over). And to keep track of this session, it returns a void pointer that must be used for all library calls using this connection. And since it's a C void pointer, it's a pointer to a particular memory location in the process, and the session can only be used in the process it was created. This causes problems with Django because (as far as I know) I can't guarantee each request in different Django views for a session will be handled within the same process. One potential method for handling the problem … -

Best way to set a referral code in django across all URLs
I wonder what's the best way to set a session id across all URLs without changing URL patterns and views. Is this a good idea to create one URL located at the top in urls.py, set a session id in the view and redirect to the url without referral code? Let me give you an example: Setting a top-level url to catch any link with referral code urlpatterns = [ re_path(r'^(.*)/ref/<str:ref_code>/$', views.set_ref_code), path('', views.index, name='index'), path('news/', views.news_list, name='news_list'), Set referral code in the session and redirect to url without referral code def set_ref_code(request, ref_code): url = request.path redirect(url) I am not sure that this example works. This is only an example to explain my idea. Maybe there is a better solution to set referral id across all the web application? -

Enforcing permissions through a related model in Django Rest Framework
I'm working on building out permissions for an API built with Django REST Framework. Let's say I have the following models: from django.db import models class Study(models.Model): pass class Result(models.Model): study = models.ForeignKey(Study) value = models.IntegerField(null=False) I have basic serializers and views for both of these models. I'll be using per-object permissions to grant users access to one or more studies. I want users to only be able to view Results for a Study which they have permissions to. There are two ways I can think of to do this, and neither seem ideal: Keep per-object permissions on Results in sync with Study. This is just a non-starter since we want Study to always be the source of truth. Write a custom permissions class which checks permissions on the related Study when a user tries to access a Result. This actually isn't too bad, but I couldn't find examples of others doing it this way and it got me thinking that I may be thinking about this fundamentally wrong. Are there existing solutions for this out there? Or is a custom permissions class the way to go? If so, do you have examples of others who've implemented this way? -
Django filter by many-to-many field doesn't work
There is a model of Article and it has many-to-many categories field. I want to filter it by that field but it doesn't work as i expected. For example: MyModel.objects.filter(categories__id__in = [0, 1, 2]) it gets model with categories 0 and 1 even if it hasn't category with id 2. i tried something like this: MyModel.objects.filter(Q(categories__id = 0) & Q(categories__id = 1) & Q(categories__id = 2)) but it even doesn't work. it doesn't even gets model if it has all of this categories. By the way, i don't want to use more than 1 filter method So, is there any solution for me? Thanks. -

In my dev environment I have no problems and everything works just fine. models.py: class Template(models.Model): def get_folder(self, filename): filename_PATH = Path(filename) template_dir = filename_PATH.stem return Path(settings.TEMPLATES_FOLDER).joinpath(template_dir, filename) name = models.CharField("template", max_length=32, unique=True) file = models.FileField("templatefile", upload_to=get_folder, null=True, max_length=260, storage=OverwriteStorage()) class OverwriteStorage(FileSystemStorage): #this is actually above def get_available_name(self, name, max_length=None): self.delete(name) return name forms.py: class TemplateAdminForm(forms.ModelForm): def __init__(self,*args,**kwargs): super().__init__(*args, **kwargs) class Meta: model = Template fields = ["name", "file", ] def clean(self): cleaned_data = super().clean() upFile = Path(str(cleaned_data["file"])) if upFile.suffix == ".zip": path = self.instance.get_folder(cleaned_data["name"]) logging.error(f"{path}") unpack_zip(path) ## works! the directory is created/filled else: raise forms.ValidationError("unknown file type ...") logging.error("DONE!") # I see this output return cleaned_data ## signal to see when the error might be happening: @receiver(post_save, sender = Template) def testing(sender, **kwargs): logging.error("we never get here") settings.py: TEMPLATES_FOLDER = PATH(MEDIA_ROOT).joinpath("TEMPLATES") but: ERROR:django.security.SuspiciousFileOperation:Detected path traversal attempt in '/opt/project/media_root/TEMPLATES/some/some' WARNING:django.request:Bad Request: /admin/appName/template/add/ -
How to get categories in django
I have a django programme of diffrent categories of books and I want to get the books in a particular category. I can do this using django, but when using rest framework I get stuck at various points.I have the following blocks of code: models.py class Category (models.Model): name = models.CharField(max_length=20, db_index=True) slug = models.SlugField(max_length=40, unique=True) class Meta: verbose_name_plural = "Categories" def __str__(self): return self.name serializers.py class categories_serializer(serializers.ModelSerializer): class Meta: model = Category fields = "__all__" views.py class product_CategoryView(generics.ListCreateAPIView): serializer_class = categories_serializer def get_queryset(self): return { "categories": Category.objects.all() } ================ class Book(models.Model): categories = models.ManyToManyField(Category) author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name="book_owner") name = models.CharField(max_length=150) slug = models.SlugField(max_length=255, blank=True, null=True) product_class = models.CharField(max_length=50) image = models.ImageField(upload_to="images/books/") .... Whenever I try to access the category using path(book/category', views.book_CategoryView.as_view(), name="book_category"),, I encounter the following error: AttributeError at /book/category Got AttributeError when attempting to get a value for field `name` on serializer `categories_serializer`. The serializer field might be named incorrectly and not match any attribute or key on the `str` instance. Original exception text was: 'str' object has no attribute 'name'. I don't understand why I am getting the error. How do I go about this? -
