Check for a certain condition before processing each view in Django
I'm building a multi-tenant Django app, where I need to check for a certain condition before processing each view, similar to the login_required decorator which checks if user is authenticated or not. And if the condition is not true, stop processing the view and send the user to the login page. How can I implement this for each view in my app My condition - def index_view(request): domain1 = Domain.objects.get(tenant=request.user.client_set.first()) domain2 = request.META["HTTP_HOST"].split(":")[0] // Condition if str(domain1) != domain2: return redirect("accounts:login") return render(request, "dashboard/index.html") -

CS50w commerce project: 'The bid must be as large as the starting bid, and must be greater than any other bids that have been placed (if any)'?
So I have solved this particular problem, but there is something that I noticed and didn't get why was it behaving the way it did. So the below code worked the way I wanted it to work: def bid_placed(request,listing_id): if request.method == "POST": recent_bid = Bid( Bid_amount = request.POST["bid_amount"], listing = Listing.objects.get(pk=listing_id) ) listing = Listing.objects.get(pk=listing_id) starting_Bid = listing.Starting_Bid recent_bid_int = int(recent_bid.Bid_amount) if recent_bid_int > starting_Bid: listing.Starting_Bid = recent_bid_int listing.save() return HttpResponse("Bid SUCCESSFULLY Placed") else: return HttpResponse("Bid CANNOT be placed") But the below code is NOT working as desired, even though the starting_Bid variable has been declared: def bid_placed(request,listing_id): if request.method == "POST": recent_bid = Bid( Bid_amount = request.POST["bid_amount"], listing = Listing.objects.get(pk=listing_id) ) listing = Listing.objects.get(pk=listing_id) starting_Bid = listing.Starting_Bid recent_bid_int = int(recent_bid.Bid_amount) if recent_bid_int > starting_Bid: starting_Bid = recent_bid_int listing.save() return HttpResponse("Bid SUCCESSFULLY Placed") else: return HttpResponse("Bid CANNOT be placed") ``` Can someone please guide, why it might be the case.?

django.db.utils.OperationalError: sequence must have same owner as table it is linked to
I am trying to update the USER auth model in Django in the middle of a project. I am also trying to learn a bit more, so I chose to do the "hard way" and switch out the standard auth model with a modified AbstractUserModel than doing the 'profile' 1-to-1 method often suggested. I feel I am quite close, as I am trying to apply the final migration with walkthrough suggestions from here and here. There is some inclination that Django runs the ALTER SEQUENCE OWNED BY with a different (auth user maybe?) user than the database user (who you are logged in as maybe?). I have confirmed that the OWNER of the tables and sequences are owned by all the same OWNER, but am still getting the migrate error. Thank you all in advance :) When trying to run ./manage.py migrate --verbosity 3, I get the following error: IN DEV XXXXXXX Operations to perform: Apply all migrations: account, … trucks Running pre-migrate handlers for application auth … Running pre-migrate handlers for application account Running pre-migrate handlers for application trucks Running migrations: Applying accounts.0004_auto_20220424_0024...Traceback (most recent call last): File "/Users/me/.virtualenvs/virtualENV/lib/python3.9/site-packages/django/db/backends/utils.py", line 84, in _execute return self.cursor.execute(sql, params) psycopg2.errors.ObjectNotInPrerequisiteState: sequence must … -
Incorrect padding when attempting to update profile picture
My project is built on React and Django. I would like to enable users to update profile information. Noticed that I was initially getting a 304 error when it specifically comes to updating the profile picture. and realized that this had something to do with Django requiring multipart form data.

Embed Plotly in html with responsive behavior: can I change legend position based on screen width?
I am using Plotly to embed a plot on an HTML page. My website is responsive, but I am not satisfied with the legend of the plot that I have embedded. Here you can see two screenshots: on the left, we see the plot on a widescreen, and on the right with a narrow one. vs As shown in the figure, the plot looks good on the widescreen (left). However, when the screen is narrow (right), the legend takes too much space and the plot is shrunk. Moving the legend below when the screen is small would solve the issue (as depicted with the red drawing). Is it possible to embed such a responsive behavior in Plotly when adding the legend? Thanks in advance! :) -
How I can use a django variable in if statement of django template into a javascript string variable

Django Polymorphic Serializer Object of type ListSerializer is not JSON serializable
I'm working on a django view to return a nested list inside another list of records, to do this I use a nested serializer. The thing is that nested serializer is a Polymorphic serializer that decomposes to many other serializers. When I'm using a normal serializer instead of the polymorphic one the approach works fine, but when I use a polymorphic serializer it gives the following error Object of type ListSerializer is not JSON serializable Here is how I'm calling the first serializer in my view return Response(serializers.FormEntriesHistorySerializer(forms,many=True,context={'device_id': kwargs.get('device_id')}).data) And this is the parent serializer class FormEntrySerializer(serializers.ModelSerializer): #form = FormSerializer(read_only=True) response_set = ResponsePolymorphicSerializer(many=True,read_only=True) class Meta: model = models.FormEntry fields = '__all__' def to_representation(self, instance): response = super().to_representation(instance) response["response_set"] = sorted(response["response_set"], key=lambda x: x["id"],reverse=True) return response def validate(self, attrs): print("Validation in on going") return attrs The error is triggered by the ResponsePolymorphicSerializer, as I said this approach works fine if I use a normal serializer instead. But in this case I need to do it with the polymorphic. Here's my polymorphic serializer's definition class ResponsePolymorphicSerializer(PolymorphicSerializer): model_serializer_mapping = { models.FreeTextResponse: FreeTextResponseSerializer, models.ShortTextResponse: ShortTextResponseSerializer, I'd gladly appreciate some guidance on this. Thanks. -

Form not submitting to database in Django
I have created a form in Django and the information from this form must be registered in the database. But I have a problem. The information is not recorded in the database.

Django Framework: Reading Data from MSSQL-Database directly? Or import the dataset to sqlite3?
I would like to build an admin dashboard in Django framework. So far I have only worked with sqlite3 databases in Django. However, the admin dashboard should read statistics from an MSSQL database and display them accordingly. (Sales figures as a graph, other sales in a table, etc.) The turnover figures are very extensive. There are several thousand entries per month and the client would like to be able to filter by any date period. Only data from the MSSQL database should be read. Writing or updating the data is not desired. So far this is no problem, but I wonder what is the better solution to implement the project. Should I connect the MSSQL database directly to Django or should I read the MSSQL database in certain intervals and cache the "results" in a sqlite3 database? Caching seems to me to be the nicer solution, as we don't need real-time data and the performance of the MSSQL server might not suffer as a result. But I would have to build an additional connector to transfer the data from MSSQL to sqlite3. How would you approach such a project? Short version: I´d like to display data in django-framework App, should … -
