Prevent Django converting python's datetime.datetime.now() to UTC
My timezone is 'America/Mexico_City' or GMT-6. In my django project I have a model called "Itinerary" which stores two fields called "visit_date" and "add_date", both of type DateTime. With "add_date" I have no problem since it is "auto_now" and is marked as non-editable, so I'm fine with it storing the time in UTC. With "visit_date" is where the problems appears, the client only sends the time of his visit, as the server automatically creates the itinerary for tomorrow: import datetime import pytz from django.utils.timezone import get_current_timezone def some_view(...): some stuff my_tz=pytz.timezone('America/Mexico_City') day = datetime.datetime.now(tzinfo=my_tz).date() + datetime.timedelta(days=1) Then it is combined with time send by client: time=datetime.datetime.strptime(request.POST['time'], r'%H:%M') new_date=get_current_timezone().localize(datetime.datetime.combine(day, time, tz=my_tz)) Itineray.objects.create(...other fields, visit_date=new_date) I'm calling django built in function localize because if not, then a "naive date" error is thrown. I'm not concerned about timestamp for "visit_date", I only need that the date remains the same according to my timezone because when time becomes 18:00 in real life, stored date turns into an extra day. i.e: actual date is 2021-01-01 + 1 day (which is my desired behavior) = 2021-01-02 and then client chosen time. With 18:00 in real life the resulting date is 2021-01-03 then client chosen time. These … -
Django - Repeated variable in path when redirecting
I'm trying to redirect my project to a different page in case there is a validation error, but for some reason, I get the variables twice. context = { "job": Job.objects.get(id=job_id) } return render(request, "trip.html", context) def update(request, job_id): errors = Job.objects.helper_validator(request.POST) print(errors) if len(errors) > 0: for key, value in errors.items(): messages.error(request, value) return redirect(f'dashboard/{job_id}/update') else: job = Job.objects.get(id=job_id) job.title = request.POST["title"] job.desc = request.POST["desc"] job.location = request.POST["location"] job.save() return redirect("/dashboard/") path('dashboard/<int:job_id>/update', views.update), the error: The current path, dashboard/5/dashboard/5/update, didn't match any of these. -
Race condition get model in django
My question is simple, I want to avoid that 2 users get the same token, imagine I have from 50 available tokens only 1, and 2 users at the same time request for the final token (AT THE SAME TIME), then I suppose this code is going to get the same available token for both: Token.objects.get(sent = False) This SHOULDNT happen, how can I avoid this type of race conditions in django? -

Django strict checking for aware timestamps
In Django, if you have USE_TZ = True and pass a naive datetime to a database call, it logs the error: DateTimeField Model.field received a naive datetime (2021-01-01 00:00:00) while time zone support is active. However, Django goes ahead and does the operation anyway, assuming the system timezone. Is there any way to do stricter checking? Is there a setting so that Django will raise an exception rather than just logging a warning? -

How can a child class access its parent attributes without the "parent.attrib" syntax in Django?
I'm totally confused in Django I can create a child class which is PostAdmin(admin.ModelAdmin) with "admin.ModelAdmin" as its parent and assign a tuple to the "list_display"(tip: list_display is an attribute of admin.ModelAdmin class) inside the PostAdmin without writing "admin.ModelAdmin.list_display"...while in python to address a parent class's attribute one needs to use the "parent.attrib" syntax and the fact is when I try admin.ModelAdmin.list_display it gives me errors! here is the code in my "admin.py": from django.contrib import admin # Register your models here. from blog.models import post class PostAdmin(admin.ModelAdmin): admin.ModelAdmin.list_display= ('title','publish', 'status') admin.site.register(post,PostAdmin) what am I missing? I've searched a lot about python inheritance and couldn't understand the way the inheritance works in here...to be exact, How the child class (PostAdmin) assigns the "('title','publish', 'status')" to its parent(ModelAdmin)? how does it get there? here are some parts of admin.ModelAdmin codes(which is made by Django and located in options.py) that I found by going to ModelAdmin's definition the first time list_display is used in options.py (where ModelAdmin is defined) class BaseModelAdmin(metaclass=forms.MediaDefiningClass): #... def get_sortable_by(self, request): """Hook for specifying which fields can be sorted in the changelist.""" return self.sortable_by if self.sortable_by is not None else self.get_list_display(request) """Encapsulate all admin options and functionality for … -
Trying login at admin Django page
I'm taking the free Django course with Prof. Charles Severance (Dr. Chuck), and at Lesson 6, I am having some troubles to login at the admin page of django, i.e. I've created successfully the username and the password, but at the moment to enter I receive this message " Please enter the correct username and password for a staff account. Note that both fields may be case-sensitive. " . source page: http://djtutorial.dj4e.com/admin I am using the Dr chuck's link "http://djtutorial.dj4e.com/admin" to login, because he said I can not use the runserver cmd line in pythonanywhere, so that, I run the manage.py cmd and then reload the web page, but the problem is still there. When I try to connect within the local host there is any connection, so, I have to use http://djtutorial.dj4e.com/admin. I have already check the username and the password with the following cmds: from django.contrib.auth.models import User user = User.objects.get(username='username') user.check_password('password') TRUE What can I do?

How to group swagger API with drf_yasg
I am doing some migration work from Django 1.11 --> 3.1.5 previously with "rest_framework_swagger", I am able to accomplish swagger api grouping just by this in url.py url(r'^api/v9/test_token1$', api.test_token, name='test_token'), url(r'^api/v9/test_token2$', api.test_token, name='test_token'), and get this (notice it groups v9) However, I have tried with "drf_yasg" on Django 3.1.5 url.py path('/v2/token_api1', token_api1, name='token_api1'), path('/v2/token_api2', token_api2, name='token_api2'), my api definition (do note I am using @api_view) token = openapi.Parameter('token', openapi.IN_FORM, type=openapi.TYPE_STRING, required=True) @swagger_auto_schema( method="post", manual_parameters=[token], operation_id="token_api1" ) @api_view(['POST']) # this is optional and insures that the view gets formdata @parser_classes([FormParser]) def token_api1(request): token = request.POST['token'] return Response("success test_api:" + token, status=status.HTTP_200_OK) token = openapi.Parameter('token', openapi.IN_FORM, type=openapi.TYPE_STRING, required=True) @swagger_auto_schema( method="post", manual_parameters=[token], operation_id="token_api2" ) @api_view(['POST']) # this is optional and insures that the view gets formdata @parser_classes([FormParser]) def token_api2(request): token = request.POST['token'] return Response("success test_api:" + token, status=status.HTTP_200_OK) however, I get this (noticed v2 does not group). And also when I did a test, there were errors as well. (Code 404 Error: Not Found) How can I group these to API in drf_yasg and also making sure there is no error ?

Django views: Using a queryset with exclude after a for loop

How can I make this so when I use exclude I'm doing so on the bytes that just went through the loop?? -

Can't access text saved in a Quill form on Django template
In my django template I want to access the bio prop of an instance of my Creator class. This bio is set up as a QuillField in the Creator model class. When I try to access creator.bio, all that renders to the page is the following: <django_quill.fields.FieldQuill object at 0x1084ce518> What I want is the actual paragraph of formatted text (ie. the bio) that I typed into the form and saved. As of now, the QuillField is only accessible through the form in the Django admin page. The problem has nothing to do with the Quill UI, but rather being able to access the text I wrote into that form field and render it to the page in a readable format.

How to get next available object or primary key from database in django
I am trying for a music player and i want to get next music from database with current music's id. So if anyone could tell how to get next primary key with current id. This is the code for getting current music. music = Contents.objects.get(id=id) The id that I passed is primary key of current music. So instead of the code above please do suggest how can I get next music.
