Firestore integration with Django
I have a Firebase Firestore database connected to a Flutter mobile application. I want to build a web application to manage the users' data and handle new users. I have decided to use Django for my web application, but I have two questions if anyone can help. First, is it actually reliable to use Django as the framework for this purpose? Second, I was trying to make a connection between Django and my existing DB to just try to call some values but I was getting this error: google.auth.exceptions.DefaultCredentialsError: Could not automatically determine credentials. Please set GOOGLE_APPLICATION_CREDENTIALS or explicitly create credentials and re-run the application. Here is the code I am using for the connection db = firestore.Client() config={ "apiKey": "******************", "authDomain": "*******.firebaseapp.com", "projectId": "*******", "storageBucket": "*******.appspot.com", "messagingSenderId": "*******", "appId": "******************", "databaseURL": "https://***********.firebaseio.com", } firebase = pyrebase.initialize_app(config) auth = firebase.auth() database = firebase.database() def index(request): doc = db.collection('test').document('test1').stream() weight= doc['weight'] return render(request, 'index.html', { "weight":weight, }) -

Call Django url namespace inside window.open
Good day, all. Currently, I want to try if the user clicks the update button on the web and then shows a popup window for updating their data. Before I have line code for updates like this: <a class = "btn btn-outline-primary" href="{% url 'help:update show.id %}">Delete</a> then I added the URL inside the window.open with an id parameter like this: onclick="window.open('update',show.id, 'newwindow', 'width=400, height=250'); return false;" the page is open but in the same tab not in the new window as I expected in the pop-up.

Django pic app code explanation, not sure why this works
so i was trying to follow along dr Chuck's Django course. In the pics app def post(self, request, pk=None): form = CreateForm(request.POST, request.FILES or None) pic = form.save(commit=False) def save(self, commit=True): instance = super(CreateForm, self).save(commit=False) # We only need to adjust picture if it is a freshly uploaded file f = instance.picture # Make a copy if isinstance(f, InMemoryUploadedFile): # Extract data from the form to the model bytearr = f.read() instance.content_type = f.content_type instance.picture = bytearr So my confusion is, instance is a model object and picture attribute in model is a binaryfiled, but in form its a FileField. So for new entry f = instance.picture, should always return null, as there is nothing in database yet. I get that 'subject' and 'text' will be retrieved when i call super as these are similar for both model and form, but instance should not have picture yet. And if it does, than this must always be true "if isinstance(f, InMemoryUploadedFile)". I know this code works perfectly, i just don't understand how. I appreciate any help. Form.py class CreateForm(forms.ModelForm): max_upload_limit = 2 * 1024 * 1024 max_upload_limit_text = naturalsize(max_upload_limit) # Call this 'picture' so it gets copied from the form to … -
django annotate with dynamic "then" value
So i have this dictionary of months below: MONTHS = { 1: "Janeiro", 2: "Fevereiro", 3: "Março", 4: "Abril", 5: "Maio", 6: "Junho", 7: "Julho", 8: "Agosto", 9: "Setembro", 10: "Outubro", 11: "Novembro", 12: "Dezembro", } And i want to annotate each of this value in a queryset, conditionally. I know i can use Case and When for that, and so am i, by doing: queryset = queryset.annotate( last_installment_month_as_string=Case( When(last_installment_month=1, then=Value(MONTHS[1])), When(last_installment_month=2, then=Value(MONTHS[2])), When(last_installment_month=3, then=Value(MONTHS[3])), When(last_installment_month=4, then=Value(MONTHS[4])), When(last_installment_month=5, then=Value(MONTHS[5])), When(last_installment_month=6, then=Value(MONTHS[6])), When(last_installment_month=7, then=Value(MONTHS[7])), When(last_installment_month=8, then=Value(MONTHS[8])), When(last_installment_month=9, then=Value(MONTHS[9])), When(last_installment_month=10, then=Value(MONTHS[10])), When(last_installment_month=11, then=Value(MONTHS[11])), When(last_installment_month=12, then=Value(MONTHS[12])), ) ) But can't i do it dynamically? Like in a for loop or something? I tried doing on a for loop, but no success whatsoever... Im looking to do something like: for key, value in MONTHS.items(): queryset = queryset.annotate( last_installment_month_as_string=Case( When(last_installment_month=key, then=Value(value)) ) ) But that doesn't work! -

how i can use django context inside context
Well I know that what I'm doing is not very feasible, but I wanted to know if there's any way to do this.I want to create a portfolio blog to post some 3d renders, for that I want to have more control over the structure of the page. for this I created two models (one for the post and another to receive the images, linking them to the post through a foreign key) so that I could have an indefinite number of images, the problem came when I decided that I wanted to be able to choose the one positioning of the images according to my need/desire, for that I did the following: I used django summernote temporarily to be able to test the written posts, I knew that it would probably not be possible to do this because the content sent from the models is static.

Let's say I want to fetch a user profile. I want to allow it to the profile owners or users belonging to the administrator group. I know how to do these two things separately. For owners: class IsOwner(BasePermission): def has_permission(self, request, view): return True def has_object_permission(self, request, view, object): if request.user.is_authenticated: return object.name == request.user.name return False And for the admin group: from django.contrib.auth.mixins import PermissionRequiredMixin class MyView(PermissionRequiredMixin, View): permission_required = ('polls.can_open', 'polls.can_edit') But how to allow either of the above?
