Authenticated Google Drive API with access token from Python Social App
I created a website that I plan to connect to Google Drive. So, when students or teachers upload files, the files will go to their respective google drive accounts. Meanwhile, the only thing that goes into the database is the file link. I've tried using Python Social Auth and implemented it successfully. But I'm still confused about how to use the access token I got to access the Google Drive API. Please help me -

Django collaboration migration issue
I currently have an issue when working with my friends on the same Django project. The situation is that every time when any of us made database changes and if other people did not migrate on time, they will get ProgrammingError: Column not exist error. That already happened a couple of times and we are still not able to figure a way to avoid this. Question: What's the best way to solve this issue when happened? What's the best process to void this issue? Thank you all! -
Django - uploading file to folder named with id of the object
I was trying to make it this way but instead of {{product.id}}, folder is named None. I read some articles about that, and I found out that is because folder is being made before whole object. So how should I do that to make it work ? models.py def getImageURL(self, filename): return "products_images/" + str(self.pk) + "/product_image.png" class Product(models.Model): name = models.CharField(max_length=200) image = models.ImageField(upload_to=getImageURL, default="media/static/products_images/default.png" ) edit: changed my funtion to def getImageURL(instance, filename): return "products_images/{}/product_image.png".format(instance.id) but it works only while edditing existing object. When I'm trying to make a new one id is set to None -
How to do typing in django model field?
With the recent addition of inlay types for python in VS Code I noticed that the typing for a Field will look like this: As you can see it is Field[Unknown, Unknown]. And as you know if you don't provide a type to a field, you won't get attribute hints for the field, and the field will be shown as Unknown. You could just provide an str type if you for example have a CharField, something like this: field: str = models.CharField() The problem is, if you want to use a strongly typed linter - it will show you an error, that the assigned value is not of type str. So I saw this inlay and I started playing around with this generic, and I noticed that the second parameter of the generic will be the type used to represent the field attribute: My question is, does anyone know what is the first parameter of the generic used for, and where is this generic even created, because inside of the package I see that the Field class does not inherit any Generics. -
Managing Django Model Class for Workout Application
I am building up a workout progress application for a learning project. When setting the class model for the project I came across to schools of thought and I don't know what is the advantages and disadvantages for reach. Here is the simply version: class Exercise(models.Model): name = models.CharField(max_length = 30) def __str__(self): return self.name class Set(models.Model): exercise = models.ForeignKey(Exercise, on_delete=models.CASCADE, related_name='sets') weight = models.FloatField(validators=[MinValueValidator(0)]) repetitions = models.IntegerField(validators=[MinValueValidator(1)]) def __str__(self): return self.exercise.name + ' set #' + str(self.pk) and the second more complicated is: class Exercise(models.Model): # Attributes name = models.CharField(null=False, blank=False, max_length=100) # Methods def __str__(self): return self.name class ExerciseSet(models.Model): # Attributes for exercise sets exercise = models.ForeignKey(Exercise, null=False, blank=False, on_delete=models.CASCADE) sets = models.ManyToManyField("my_gym.Set", related_name="sets") number_of_sets = models.IntegerField(null=False, blank=False, default=3) # Methods def __str__(self): return str(self.exercise.name) + " - " + str(self.number_of_sets) + " sets" class Set(models.Model): # Attributes reps = models.PositiveIntegerField(null=False, blank=False, default=0) weight = models.DecimalField(max_digits=5, decimal_places=2) # Methods def __str__(self): return ( str(self.reps) + " " + " x " + str(self.weight) + " " ) The requested project outcome is to just to set the progress of the workout logging the weight and reps of each excercise.

How to add constant fields to Wagtail form builder
I have created job application form with Wagtail form builder.

Applying different CSS style for each element in For Loop - Django
I'm building a blog with Django and i'm trying to apply my static design to dynamic HTML templates. I have several CSS classes for diffrenet card types (regular, medium and large), and i'm builing a posts page that should display all posts from all classes.

Use TokenAuthentication AND SocialAuthentication from AllAuth

How does Django work with react combined?
I just started out with Django, I got a litte bit experience in React though. So, there is one topic that confuses me a litte... If I google how Django works with React, I mostly see 2 ways. The first on works by putting React right into Django and the second is by using a Rest-API. I Think that the two ways follow different approaches in terms of that the first way is for using React directly in the backend (so as a part of the backend) and the second option uses React in the Frontend and communicates via the API with the backend. IF I am wrong at this point then please show me the right way... So, IF I am right, what is the goal of using React inside of Django, if you already have the possibilities of using variables, functions or even classes? Just because of JS instead of Python? Or do I overlook something? -

NOTE: I would post the full Code def registerRef(request, *args, **kwargs): if request.user.is_authenticated: return redirect('core:index') profile_id = request.session.get('ref_profile') print('profile_id', profile_id) try: signup_point = SignUpPoint.objects.get() except: signup_point = None code = str(kwargs.get('ref_code')) try: profile = Profile.objects.get(code=code) profile_user = Profile.objects.get(code=code) request.session['ref_profile'] = profile.id print('Referer Profile:', profile.id) except: pass print("Session Expiry Date:" + str(request.session.get_expiry_age())) form = UserRegisterForm(request.POST or None) if form.is_valid(): if profile_id is not None: recommended_by_profile = Profile.objects.get(id=profile_id) ref_earn = InvestmentPackageID.objects.get() instance = form.save(commit=False) instance.email = instance.email.lower() instance.username = instance.username.lower() instance.save registered_user = User.objects.get(id=instance.id) registered_profile = Profile.objects.get(user=registered_user) registered_profile.recommended_by = recommended_by_profile.user my_recomended = Profile.objects.filter(recommended_by=profile_user.user).values_list('user__id', flat=True) print(my_recomended) # second_level_recommended=Profile.objects.filter(recommended_by__in=my_recomended) registered_profile.save() profile = Profile.objects.get(user=registered_user) profile.earning_point = signup_point.signup_point profile.main_all_earning += signup_point.signup_point profile.save() if recommended_by_profile.level_1 == True and recommended_by_profile.level_6 == False and recommended_by_profile.level_5 == False and recommended_by_profile.level_4 == False and recommended_by_profile.level_3 == False and recommended_by_profile.level_2 == False: recommended_by_profile.referral_point = recommended_by_profile.referral_point + ref_earn.ref_earn1 recommended_by_profile.main_all_earning = recommended_by_profile.main_all_earning + ref_earn.ref_earn1 recommended_by_profile.save() else: recommended_by_profile.referral_point = recommended_by_profile.referral_point … -
UnboundLocalError at /update-skill
I can't figure out why I can't fix this code after reading other people's similar issues. When I click the Edit Skill icon on my site, I get this Error Message: UnboundLocalError at /update-skill/39152d45-8e94-4982-9f36-16cbd96d80f7/ local variable 'profile' referenced before assignment The code I have for the EditSkill looks like this: @login_required(login_url='login') def editAccount(request): profile = request.user.profile form = ProfileForm(instance=profile) if request.method == 'POST': form = ProfileForm(request.POST, request.FILES, instance=profile) if form.is_valid(): form.save() return redirect('account') context = {'form': form} return render(request, 'users/profile_form.html', context) I've looked at the code repeatedly and clearly can't pinpoint my error. Advice would be excellent! Thanks! -
I can’t save form in database, sqlite3
I can’t seem to save anything to database,it returns, the code works fine. It redirect me to the url after the save function is called but nothing in database, I tried checking like this obj = form.save() print(f'saved object with pk={obj.pk}') It returned “Save object with pk=None”
