OSMnx I want to get the time distance of the routes in minutes
Right now I have in meters, how do I convert them to minutes? orig_node = ox.nearest_nodes(G, X=fromLatLng[1], Y=fromLatLng[0]) dest_node = ox.nearest_nodes(G, X=toLatLng[1], Y=toLatLng[0]) # gets route in meters pathDistance = nx.shortest_path_length(G, orig_node, dest_node, weight='length') print('pathDistance: ', pathDistance) Here is an example of what it printed from one of my route distances. pathDistance: 3192.146999999999 Here are some more information: I don't know how much 3192.146999999999 Meters are in minutes. It would be hard to know when roads got different speed limits and also traffic lights. The vehicle type I'm using is Motorcycle or car, but I think I will mostly use Motorcycles, I don't even think I will use car, but maybe I will. I'm also doing this in Django, so not sure if Django would make this any easier. -

Refresh a page when something new appears in Django
I'm creating a website for a local establishment that uses Ifood. Ifood provides an API that allows you to check information, both regarding establishments and incoming orders. The code is ready, but I can only show a new order update when manually refreshing the page. Which is a bit shippable. I thought about putting an automatic update with JavaScript at the given time, but it would be an ugly workaround. In this case, I'm getting JSON data, but in a more general context. How could I refresh the page as soon as new data appears? -

Is there a way to add the date field in models in a "from to" pattern for billing periods - Django
I am trying to add a billing period in the invoices that I am generating. Currently my model contains two seperate date fields, one that stores the start date of the billing period and the other stores the end date of the billing period. The model looks as below class Bill(models.Model): billing_period_start = models.DateField(null=True, blank=True) billing_period_end = models.DateField(null=True, blank=True) Question : Is there a way to add the two seperate date fields in a same model field so that I can get a from "DateField" to "DateField" pattern in the admin pannel and have the billing period in a single field. -

Django, relating model to another app models field
First off this may not be the best way to set this up, however, I'm learning as I go and struggling to find the correct answer. I have an Account app which handles the user signup, I added the couple_choice option which I'm trying to get in another app's model. ACCOUNT model class Account(AbstractBaseUser): COUPLE_CHOICE = Choices('single', 'couple') email = models.EmailField(verbose_name="email", max_length=60, unique=True) username = models.CharField(max_length=30, unique=True) date_joined = models.DateTimeField(verbose_name='date joined', auto_now_add=True) last_login = models.DateTimeField(verbose_name='last login', auto_now=True) is_admin = models.BooleanField(default=False) is_active = models.BooleanField(default=True) is_staff = models.BooleanField(default=False) is_superuser = models.BooleanField(default=False) profile_image = models.ImageField(max_length=255, upload_to=get_profile_image_filepath, null=True, blank=True, default=get_default_profile_image) hide_email = models.BooleanField(default=True) couple_choice = models.CharField(choices=COUPLE_CHOICE, default='single', max_length=20) I then have another app Profile, which I want to make the couple = to the Account.account.couple_choice, or if the Account.couple.choice is 'couple' then Profile.couple = True from account.models import Account class Profile(models.Model): user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE,blank=True, null=True, related_name="swinger") couple = models.ManyToManyField(Account, to_field="couple_choice", blank=True, null=True,related_name="is_couple", on_delete=models.CASCADE) PLease let me know the best way to do this?

Use original template under admin directory
I have django script with administration page /admin Now I want to make another page /customdata for administration purpose. However in this page , customdata is not related to specific model, it just shows the system overview data. It is just the normal template. Now I have two ideas. Making independent www.myexample.com/customdata page and set authentication. Linking this under www.myexample.com/admin/customdata and treat it as admin page 2 sounds usefule to me, because pages for administration purpose should be togetter. However is it possible? or is it not good behaivor? -
Django (django-rest-framework) with Bootstrap Autocomplete. Filed Nameing
I want to autocomplate a field. But i can't figure out how i can accomplish properly because i don't know yet what is the industry standard. Seems to be the Bootstrap Autocomplete expect an particular field naming like this. I think this is hardcoded. (the "text" at least): [ { "value": 1, "text": "Google Cloud Platform" }, { "value": 2, "text": "Amazon AWS" }, { "value": 3, "text": "Docker" }, { "value": 4, "text": "Digital Ocean" } ] How i can alter/mask the filed names from ['id','provider'] to ['value','text'] in Django side? Let say i have: #modell class CloudProviders(models.Model): provider = models.CharField(max_length=255, blank=True, null=True) #id come by default ... #Serializer class CloudProvidersAutocompleteSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = CloudProviders fields = ['id','provider'] #view class CloudProvidersAutocomplete(viewsets.ModelViewSet): model = CloudProviders serializer_class = CloudProvidersAutocompleteSerializer def get_queryset(self): query= self.request.query_params.get('search') if query : data = CloudProviders.objects.filter(provider__contains=query) return data UPDATE I have a solution but the question still open, because i don't know if this is a proper solution: #modell class CloudProviders(models.Model): provider = models.CharField(max_length=255, blank=True, null=True) #id come by default def _getProvider (self): return self.provider text = property(_getProvider ) ... -

Is it possible to store aware datetime objects in django with different timezones for the values?
I've seen many different posts across SO about aware timezones in django (i.e. datetimes with a timezone value). Even converting naive datetime to aware I've read online that many applications that deal with timezones usually store everything in UTC to avoid any Day light savings conversions and then use frontend to handle the conversions. I'd like to know if it's possible to store an aware datetime with the actual timezone in my database. If so, how would I go about it? So instead of storing something like: 2022-10-13 13:56:00+00:00 I'd like to store: 2022-10-13 13:56:00+04:30 (US/Eastern) -
