Use multiple databases in Django with only one table "django_migrations"
For a project in Django I have to use two databases: default and remote. I have created routers.py and everything works fine. There was a requirement to create a table on the remote database and I created migration, run it and the table django_migrations was created. I want to have only one table django_migrations, in the default database. The relevant part of routers.py is here: class MyRouter(object): # ... def allow_migrate(self, db, app_label, model_name=None, **hints): if app_label == 'my_app': return db == 'remote' return None I run the migration like this: python manage.py migrate my_app --database=remote Now when I do: python manage.py runserver I get the following warning: You have 1 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): my_app. Run 'python manage.py migrate' to apply them. The tables for my_app are created in the remote database, and in django_migrations inside the remote database the migrations are marked as applied. How to force Django to use only one table django_migrations, but still apply the migrations into different databases? -
Mistakes in custom pagination Django Rest Framework
I am using APIView in myproject and custom pagination also it is working but it shows same elements multiple time. Here I have tried so far. views.py class ProductByBrand(APIView): pagination_class = LimitOffsetPaginationUpperBond @property def paginator(self): if not hasattr(self, '_paginator'): if self.pagination_class is None: self._paginator = None else: self._paginator = self.pagination_class() return self._paginator def paginate_queryset(self, queryset): if self.paginator is None: return None return self.paginator.paginate_queryset(queryset, self.request, view=self) def get_paginated_response(self, ctx): assert self.paginator is not None return self.paginator.get_paginated_response(ctx) def get(self, request, slug, brand, format='json'): pid = Category.objects.get(slug=slug) data = Category.objects.filter(parent_id=pid) data_categories = [] for category in data: data_categories += Category.objects.filter(parent_id=category.id) all_product = [] for data_category in data_categories: all_product += Product.objects.filter(category_id=data_category.id, brand=brand) print(all_product) ctx = [] for product in all_product: str = settings.MEDIA_URL + product.image.name ctx.append({ 'id': product.id, 'name': product.name, 'slug': product.slug, 'brand': product.brand_id, 'image': str, 'price': product.price, 'rating': product.rating, 'discount': product.discount }) queryset = Product.objects.all() page = self.paginate_queryset(queryset) if page is not None: return self.get_paginated_response(ctx) to be more precise I select brand in category section to filter the products related to that category.

Django - Receiving error "too many values to unpack (expected 2)"
In my website, I have created a custom user from the AbstractUser class. When I check if a user with the same username or email exists, I get a value error returned to me. Here's my code: models.py: class Account(AbstractUser): pass def __str__(self): return self.username def __unicode__(self): return self.username views.py: try: user = Account.objects.get(username=request.POST['username']) return render(request, 'users/signup.html', {'error': 'Username has already been taken'}) except Account.DoesNotExist: try: user = Account.objects.get(request.POST['email']) return render(request, 'users/signup.html', {'error': 'Email is not available'}) except Account.DoesNotExist: user = Account.objects.create_user(username=request.POST['username'], email=request.POST['email'], password=request.POST['password']) auth.login(request, user) return redirect('home') Error returned: ValueError at /accounts/signup/ too many values to unpack (expected 2) Traceback: user = Account.objects.get(username=request.POST['username']) Does anybody have a solution?

saving in the database after return user?
here I use essentially Django cookie cutter, to be able to save with a custom shape sign I had to proceed in this way, it works, I'm not sure it's the right way to proceed but I only found this one. I also tested with def Signup() but no results But I realized that the user is not directly saved in the database for this test I put a timer between alt_user and alt_user.name . I noticed that User.object.get gives me the user and that I can modify the rest of the user's information. But when I look at my database, the user's backup is only done after the user returns. Is the user cached before the backup? The problem it poses and that after saving Alt_user.save() I send the id of the one if in a celery task for a longer calculation, thanks you in advance User = get_user_model() class CustomSignupForm(SignupForm): name = CharField( max_length=255) forename = CharField( max_length=255) street = CharField( max_length=255) street_number = IntegerField() city = CharField(max_length=255) country = CountryField().formfield() phone_number = IntegerField() date_of_birth = DateField() affiliate_link = IntegerField(required=False) class Meta: model = get_user_model() # use this function for swapping user model def save(self, request): # Ensure … -

Pass image from React to Django - The submitted data was not a file. Check the encoding type on the form
I'm trying to pass image via fetch and POST request to Django. Actually it works if I pass it via Postman, it appears in database, and then I can display it on my React page via GET request. Problem is that I can't pass anything to backend using my app. I already wrapped everything into FormData() but still i keep getting error that "The submitted data was not a file. Check the encoding type on the form". Any idea how to fix it? The problem is on backend or front-end part? First I grab image via react-dropzone, then cut it a bit with react-cropper and then try to pass it to django.

Perform translation (internationalization) using ugettext_lazy in models.py for a dynamic variable
I have a django project where there are multiple models defined and each model have some set of fields with choice fields. These values are being displayed on template using a loop. I have multiple languages defined and using ugettext_lazy, I am able to show the translated value as per the language selected by user. Now I am trying to move these values into database, fetch them and use it in ugettext_lazy for translation. e.g. _(value_from_db) Problem is when using from database, the value doesn't translate whereas when using it as hardcoded e.g. _("translated_val") models.py from django.utils.translation import ugettext_lazy as _ from translated_fields import TranslatedField class ModelClass(models.Model): choices_values = ( (dataframe[(dataframe['name'] == 'State1')]['code'].item(), _("State1")), (dataframe[dataframe['name'] == 'State2']['code'].item(), _(dataframe[dataframe['name'] == 'State2']['value'].item())), (State3, _("State3")) ) In the above example, the translation works properly for State1, State3 but not for State2. I expect State2 to be translated on my template. P.S. All the translation activities have been done properly and are working (if I replace the dataframe fetch for state2 with hardcoded value, it gives the proper tranlation and also the dataframe fetches the same value as the one I had hardcoded) Thanks for the help. -

Is there a way to execute html inside of a template variable that is a table?
I am creating a website using Django and I have taken a pandas dataframe and stored it as a template variable and passed it to the render request. I would like to make some columns form elements but have been unsuccessful into how to do that. I have already tried applying the function to the pandas dataframe in order to add the proper HTML to each element in the column. However, the HTML itself shows up on the actual site.

How to add different models to only one model in django?
I have some models that are used to make one order per dining table. My goal is to have different dining tables, these always have a total order and the total order has individual orders. I have difficulties when i create a second dining table, with a second total order, to avoid taking orders (relationship) from the first table. How can i make a total order that has his own orders, without any relationships from other orders? Here my models: class Order(models.Model): Beer = models.ForeignKey(Beer, on_delete=models.SET_NULL, blank=True, null=True, related_name='beer') SoftDrink = models.ForeignKey(SoftDrink, on_delete=models.SET_NULL, blank=True, null=True, related_name='soft_drink') ForeignBeer = models.ForeignKey(ForeignBeer, on_delete=models.SET_NULL, blank=True, null=True, related_name='foreign_beer') Liquor = models.ForeignKey(Liquor, on_delete=models.SET_NULL, blank=True, null=True, related_name='liquor') Wine = models.ForeignKey(Wine, on_delete=models.SET_NULL, blank=True, null=True, related_name='wine') BarDrink = models.ForeignKey(BarDrink, on_delete=models.SET_NULL, blank=True, null=True, related_name='bar_drink') Meal = models.ForeignKey(Meal, on_delete=models.SET_NULL, blank=True, null=True, related_name='meal') class TotalOrder(models.Model): Order = models.ManyToManyField(Order, related_name='order') Total_Price = models.DecimalField(default=0, max_digits=6, decimal_places=2) class Table(models.Model): Number = models.IntegerField(unique=True) Total_Order = models.ForeignKey(TotalOrder, on_delete=models.SET_NULL, related_name='total_order', blank=True, null=True) Thanks in advance :D -

Set GOOGLE_APPLICATION_CREDENTIALS environment variable in VSCode debugger
I'm testing Google Cloud Pub/Sub on my Django project using VSCode on my Mac, and I'm having some problems setting GCP environment variables during debugging tests, specifically the GOOGLE_APPLICATION_CREDENTIALS environment variable. I am able to set the GOOGLE_APPLICATION_CREDENTIALS for running server and/or tests locally with export GOOGLE_APPLICATION_CREDENTIALS="path/to/json_credential_file.json" in a shell, but as the VSCode debugger runs in a separate shell the env variable is not set when debugging tests. I tried adding the same value to the env key in launch.json: "env": { "GOOGLE_APPLICATION_CREDENTIALS": "path/to/json_credential_file.json" } But it still complains about GOOGLE_APPLICATION_CREDENTIALS not being set: oauth2client.client.ApplicationDefaultCredentialsError: The Application Default Credentials are not available. They are available if running in Google Compute Engine. Otherwise, the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials. See https://developers.google.com/accounts/docs/application-default-credentials for more information. Any ideas? -
Django multiple ModelForms from one Model
I need to implement a transaction with a step by step process wherein the user can input the details in step 1 and then process the inputted data which will do some calculations. The user can then proceed to step 2 which displays the initial result and he/she can input additional parameters to manipulate the results. I need to store all user inputs in one model so that if the user cancels the process, all data that was initially stored will be deleted. I am a newbie in django and python so if anyone know how to solve this problem I would really appreciate it. This is what I've tried so far: In my models.py I have: class Calculate(models.Model): date_created = models.DateField(auto_now_add=True) user = models.ForeignKey(get_user_model(), on_delete=models.CASCADE) csv = models.FileField(upload_to='files/') param1 = models.CharField() param2 = models.CharField() param3 = models.CharField() In my forms.py I have: class DetailsInputForm(forms.ModelForm): class Meta: model = Analysis fields = ('date_created', 'csv',) class ParamInputForm(forms.ModelForm): class Meta: model = Analysis fields = ('param1', 'param2', 'param3',) In my views.py I have: class DetailsInputView(LoginRequiredMixin, CreateView): model = Calculate form_class = DetailsInputForm template_name = 'step1.html' login_url = 'login' success_url = reverse_lazy('step2') class ParamInputView(LoginRequiredMixin, CreateView): model = Calculate form_class = ParamsInputForm template_name = … -

How to setup a Django-site where users have different permissions for different projects
Kind stacky! Hopefully you can help me out. I'm trying to workout a framework on which I can relatively easily develop django-apps and distribute them to the users. Users can use these apps within a 'project' environment, so the data they see in that app is only related to the project they are currently looking at. I'm not referring to Django-projects here, but projects as in a task on which multiple people are working together. :) Users should be able to create a project and invite other users. If a user has no permission for a certain project he cannot access the project. Questions that are spooking through my head are: How do I need to setup my model? How do I go about setting up permissions? How do I make sure they can not access project data to which they don't have permissions. I understand there is not one true solution, but I am looking for recommendations on best practices or working examples. I just don't know how to start. I already searched the internet extensively but I can't find anything that resembles what I want to do. My line of thought currently is to create a project class … -

How to do Filtering in Djnago?
I have a page where all transaction records are displayed. I want to narrow down the search for key points that are visible in the screenshot. How to implement a search?
