How do I properly compare two different models based on their field values and output the differences?
I am trying to figure out how to produce the output between two querysets that have similar fields. I have two different models where I keep identical fields, and at times I want to show the differences between these two models. I have researched and successfully used sets and lists in my python code, but I can't quite figure out how to leverage them or determine if I Can. Sets seems to strip out just the field values, and when I try to loop through my sets, it doesn't currently work because it's just the values without the keys. Example: class Team(models.Model): player = models.Charfield coach = models.Charfield class TeamCommittee(models.Model): player = models.Charfield coach = models.Charfield I want to be able to query both models at times and be able to exclude data from one model if it exists in the other. I have spent the afternoon trying to use sets, lists, and loops in my django templates but can't quite work this out. I have also tried various querysets using exclude.... I tried something like.... query1 = TeamCommittee.objects.filter(id=self.object.pk).values('coach','player') query2 = Team.objects.filter(id=self.object.pk).exclude(id__in=query1) When I use the approach above, I get TypeError: Cannot use multi-field values as a filter value.

How to check user type and direct them to respective pages in Django?

Django: Reverse not found. 'teachers_detail' is not a valid view function or pattern name
I'm new in django. I am using this tutorial https://developer.mozilla.org/en-US/docs/Learn/Server-side/Django/Generic_views, but can't get the right work of my application.

Django Annotate with additional data
I have a model of Courses and Categories for the courses which is a choice field.

Django RestAPI - only allow access to users data with JWT Authentication

How can a call be made to the Google API from within Django?
I am currently trying to build a web app using Python and Django which will require information from the Google Calendar API. I've successfully managed to create the specific API credentials that I need using the Google Cloud Console, and downloaded the client secret JSON file to use for authentication. I have also been able to successfully access the API using the following code snippet: from googleapiclient.discovery import build from google_auth_oauthlib.flow import InstalledAppFlow scopes = ['https://www.googleapis.com/auth/calendar'] flow = InstalledAppFlow.from_client_secrets_file(r"client secret file location", scopes=scopes) flow.run_console() When I run it in VSCode, it creates a link in the terminal that I can click to go to the Google site and login. The issue I'm now having though is that the API is treating this as a PC app call, and once it opens in my browser it's asking me to recreate the API key (since the one I created is for Web Apps). A picture of the error can be seen here: Authorization Error Message from Google Now my question is, is there a way to call the API and have the user login be verified using Django? I am hesitant to remake the API credential as a desktop app because what … -

How can I set model items in html properly?
I have a form with which I intend to capture student marks.

Django Form initial Value For Foreignkey Field
I have two django models which are : class Dataset(models.Model): name = models.CharField(max_length = 200) description = models.CharField(max_length=1000) owner = models.ForeignKey(Profile, null=True, on_delete=models.SET_NULL) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) class Source(models.Model): name = models.CharField(max_length = 200) description = models.CharField(max_length=1000) dataset = models.ForeignKey(Dataset, null=True, on_delete=models.SET_NULL) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) When saving a Source, I would like to initiate the value of the corresponding Dataset. I tried to initiate the value of my form as suggested here : foreign key as initial value not passed to the ModelForm in django def create_source(request, dataset_id): user = request.user dataset = Dataset.objects.get(id=dataset_id) form = SourceForm(initial={"dataset" : dataset, }) if request.method == "POST": form = SourceForm(request.POST or None, initial={"dataset" : dataset, }) if form.is_valid(): source = form.save() # dataset.source_set.add(source) # Only works if I add this line return redirect("source", dataset_id=dataset_id, source_id=source.id) context = {"form": form} return render(request, "sources/source_form.html", context) The suggested way does not work. I was able to achieve the desired result by adding the commented line above. It is not a recommended solution since it makes a second call to the database. Any idea how to give properly the dataset object to the source ? -

I want to write my own python package inside django's app. It looks like that: I have secondary app. It totally works except one thing. Someday I'd decided to make my app more structured. And there where problems started. First of all, I've added python package(with simple init.py inside directory) to the app. Then I've added second package inside that package. And when I try to run django.setup() inside packages' files, I'm getting this error: ModuleNotFoundError: No module named '<primary settings container module name goes here>' How to make my custom package's functions working properly?
