is it possible to add db_index = True to a field that is not unique (django)
I have a model that has some fields like: current_datetime = models.TimeField(auto_now_add=True) new_datetime = models.DateTimeField(null=True, db_index=True) and data would be like : currun_date_time = 2023-01-22T09:42:00+0330 new_datetime =2023-01-22T09:00:00+0330 currun_date_time = 2023-01-22T09:52:00+0330 new_datetime =2023-01-22T09:00:00+0330 currun_date_time = 2023-01-22T10:02:00+0330 new_datetime =2023-01-22T10:00:00+0330 is it possible new_datetime to have db_index = True ? the reason i want this index is there are many rows (more than a 200,000 and keep adding every day) and there is a place that user can choose datetime range and see the results(it's a statistical website). i want to send a query with that filtered datetime range so it should be done fast. by the way i am using postgresql also if you have tips for handling data or sth. like that for such websites i would be glad too hear thanks. -

Encrpyt URL Id in django
I was trying to excrypt Update URL id to encrpyted format in the url. from my profile page of a user one edit button is there. that button contains url of the update view. #My profile page. code def profile(request): lst = request.user.id #This line is the problem l=[] for i in lst: i['encrypt_key']=encrypt(i['id']) i['id']=i['id'] l.append(i) return render(request, 'profile.html', {'lst':l}) #The update view code def update(request, id): id=decrypt(id) #Update code. return render(request, 'edit_profile.html', context) In the profile page for that edit button, since it is an iteratable for loop I coded like this is the Html template <li class="ctx-item"> <button class="ctx-menu-btn icon-box"> <span class="material-symbols-rounded icon" aria-hidden="true">edit</span> {% for x in lst %} <span class="ctx-menu-text"><a href="/update/{{x.encrypt_key}}">Edit</a></span> {% endfor %} </button> </li> Since three users are there in my database, three edit links are coming. To restrict it in the profile view I have to change the filteration while retriving the user in lst. If i put request.user.id, It is showing the following error.

django_bootstrap5 not formatting anything
I'm trying to get basic bootstrap formatting working in a django app, and installed django_bootstrap5 to do so. No formatting, however, is getting applied to any of the pages. Here's the various pages: base.html: <!DOCTYPE html> {% load django_bootstrap5 %} <html lang="en"> <head> <meta charset="UTF-8"> <title> {% block title %} {% endblock %} </title> </head> <body> <div class="container"> {% block body %} {% endblock %} </div> </body> </html> I extend this in a simple index page: <!DOCTYPE html> {% extends 'base.html' %} {% load django_bootstrap5 %} {% block title %} Home {% endblock %} {% block body %} <h1>Hello World</h1> {% endblock %} Hello World, however, is not showing up in a container. This is also failing on a form page: <!DOCTYPE html> {% extends 'base.html' %} {% load django_bootstrap5 %} {% block body %} <div class="container"> <h1>Sign Up</h1> <form method="POST"> {% csrf_token %} {% bootstrap_form form %} <input type="submit" value="Sign Up" class="btn btn-default"> </form> </div> {% endblock %} The form is neither in a bootstrap container, nor does it have any styling at all. What am I missing here? Thank you. -
How can I skip pk in url while redirecting to another url with generic RedirectView in Django?
I am trying to delete a record after displaying it with DetailView and redirecting to the list page again. view.py ... class DailyRecordDeleteConformationView(RequiredBasicDetailsAndContextMixin, DetailView): model = DailyRecord obj_not_found_redirect = reverse_lazy('business:add_daily_records') template_name = 'business/daily_records_detail.html' context_object_name = 'record' def get_object(self): detail = self.model.custom_obj.get_single(self) return detail class DailyRecordDeleteView(RequiredBasicDetailsMixin, RedirectView): pattern_name = 'business:daily_records' def get_redirect_url(self, *args, **kwargs): # Delete the record return super().get_redirect_url(*args, **kwargs) ... urls.py ... path('daily-records/', DailyRecordView.as_view(), name='daily_records'), path('daily-records/<int:pk>/', DailyRecordDeleteConformationView.as_view(), name='daily_record_detail'), path('daily-records/<int:pk>/delete/', DailyRecordDeleteView.as_view(), name='daily_record_delete'), ...

I tryed to find any variable for RedirectView or something that can skip the pk of current url while redirecting to another url. Thanks. -
how do python handle asynchronous task
I've strong background in a JS frameworks. Javascript is single threaded language and during the execution of code when it encounters any async task, the event loop plays the important role there. Now I've been into Python/Django and things are going good but I'm very curious about how python handle any asynchronous tasks whenever I need to make a database query in django, I simple use the queryset method like def func(id): do_somthing() user = User.objects.get(id=id) do_somthing_with_user() func() another_func() I've used the queryset method that fetch something from database and is a asynchronous function without await keyword. what will be the behaviour of python there, is it like block the execution below until the queryset response, is it continue the execution for the rest of code on another thread. Also whenever we need to make an external request from python, we uses requests library method without await keyword, r = request.get("https://api.jsonplaceholder.com/users") # will the below code executes when the response of the request arrive? do_somthing() . . . do_another_thing() does python block the execution of code until the response arrives? In JS the async task is handled by event loop while the rest of the code executes normally console.log("first") fetch("https://api.jsonplaceholder.com/users").then(() … -

DRF, why my root api urls are got mixed (combined)?
These are my code snippets: # serializers.py from rest_framework import serializers from .models import User class UserSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = User fields = '__all__' class UserActivitySerializer(serializers.HyperlinkedModelSerializer): class Meta: model = User fields = ( 'id', 'email', 'last_login', 'last_requested_at', ) # urls.py router = routers.DefaultRouter() router.register(r'users', UserViewSet) router.register(r'user-activity', UserActivityViewSet) urlpatterns = [ path('', include(router.urls)), ] This leads to combined Root API urls, like so: However this is not the expected behavior. I wanted 2 separate urls. First with all users (for example, localhost:8000/users with all users and localhost:8000/users/ for specific user). And second with user activity API. with those 4 fields. I don't have clue why my urls got combined when I added router.register(r'user-activity', UserActivityViewSet) to my urls.py. Please help with broad explanation, if possible. Thanks! -

Django: cannot cast type integer to time without time zone
I've had some previous testing with models and their functionality integration. There were few fields that were using for time input. At first I thought maybe IntegerField will be enough, but as we continue with more new solutions things changed. So there was check_in_time, check_out_time and etc. Now we want to set it to TimeField, but as we are trying to apply the migrations those errors appear. I'm not an postgres guru so I'm scared of breaking things up, cuz migrations might be an pain in the ass. This is the new migration: class Migration(migrations.Migration): dependencies = [ ('property', '0084_rename_max_tenants_property_max_guests_allowed'), ] operations = [ migrations.AlterField( model_name='property', name='check_in_after_time', field=models.TimeField(null=True), ), migrations.AlterField( model_name='property', name='check_in_before_time', field=models.TimeField(null=True), ), migrations.AlterField( model_name='property', name='check_out_after_time', field=models.TimeField(null=True), ), migrations.AlterField( model_name='property', name='check_out_before_time', field=models.TimeField(null=True), ), ] This is our fields that we want to use it right now as TimeFields: check_in_before_time = models.TimeField(null=True) check_in_after_time = models.TimeField(null=True) notice_days_before_check_in = models.PositiveIntegerField(default=0) check_out_before_time = models.TimeField(null=True) check_out_after_time = models.TimeField(null=True) How can I fix it now and prevent it from happening again when migrating this on other servers?

This particular block of code repeats about a hundred million times, just with different form fields, and so I want to replace all those lines with templatetags: <label for="{{ form.building_name.id_for_label }}">Building</label> <input name="{{ form.building_name.name }}" value="{{ form.instance.building_name }}"> So instead of writing this: <label for="{{ form.building_name.id_for_label }}"> <!-- plus many more lines just for this one element --> <label for="{{ form.building_title.id_for_label }}"> <!-- plus many more lines just for this one element --> ... I am looking to write this: {% someTag 'building_name' %} {% someTag 'building_title' %} After much mucking about, I arrived at one of the ugliest ways of writing an inclusion tag that I've ever had the misfortune of laying eyes on. The convoluted nature of accessing the field is because I found no other way of accessing an arbitrary field of the form. The tag: @register.inclusion_tag("main/sff.html") def sff(form, field_name, label): field = form._meta.model._meta.get_field(field_name) return {'form': form, 'field': field, 'label' : label, 'ph' : placeholder} sff.html: <label for="{{ field.id_for_label }}">{{ label }}</label> <input type="text" \ name="{{ field.name }}" \ value="{{ form.instance.field }}"> </div> With all of that said and done, here's how I call it from my HTML template: {% sff form 'building_name' 'Enter property name' %} … -

OAuthlib thinks request is insecure because of reverse proxy
I have noticed that for every request, request.scheme is http. I can't find any official source why, but I have been told by my peers this is because of Cloudflare acting as reverse proxy and a tls terminator, causing my server's hosting provider to see http instead of https. One part of my app uses the Google Classroom API, and I have configured a callback to a secure endpoint of my server. Upon attempting to fetch a token from the callback's absolute uri, oauthlib raises oauthlib.oauth2.rfc6749.errors.InsecureTransportError: (insecure_transport) OAuth 2 MUST utilize https. because it thinks the request is http and insecure. I have researched and found out I can set os.environ['OAUTHLIB_INSECURE_TRANSPORT'] = '1' to mitigate this issue, but I am hesitant to do so because I am unsure if that compromises security. My thought process is to manually change the request url to https when I'm absolutely sure it is secure. Inspecting request.META to find which headers are set in the case of a reverse proxied http request, the code looks like this: authorization_response = request.build_absolute_uri() if ( authorization_response.startswith("http://") and request.META["HTTP_X_FORWARDED_PROTO"] == "https" and request.META["HTTP_ORIGIN"].startswith("https") and json.loads(request.META["HTTP_CF_VISITOR"])['scheme'] == "https" ): authorization_response = "https://" + authorization_response[7:] ... fetch the token passing … -
Is there a way to clear the cache of a django form field in the admin page?
My problem is that, on the website I created using django and hosted with apache, after modifying some models through the admin interface I noticed that there is a URLField that whenever the page is reloaded after I make changes this field always loads in the browser with a value in it (even though that field is null in the database) and whenever I forget to check that field and save the model the field will contain that "cached" value that was loaded with the page and save it in the database, and I don't want that. There is also this piece of code in the ModelAdmin class for the model with the described problem that I thought it was the cause of the problem but I don't think it's from this def get_form(self, request, obj=None, change=False, **kwargs): form = super(ResourceAdmin, self).get_form(request, obj, change, **kwargs) if obj and obj.yt_video_id: form.base_fields['youtube_url'].initial = f'https://www.youtube.com/watch?v={obj.yt_video_id}' return form I tried CTRL + F5 since I heard that this way of refreshing clears the cached resources for that website but it didn't work. Is there a way of getting rid of that value that loads in the field whenever I am changing a model on …
