Django dynamic url redirecting to 404
I'm trying to create a dynamic URL pattern where there's an ID passed into the URL and used the retrieve a piece of information from the database. Here's the definition of the pattern: urlpatterns = [ path('',views.index,name='index'), path('<int:question_id/>', views.detail,name='detail'), path('<int:question_id>/results/',views.results,name='results'), path('<int:question_id>/vote/',views.vote,name='vote') ] and here's the piece of code used to retrieve the information: def detail(request, question_id): question = get_object_or_404(Questions, pk = question_id) return render(request, 'polls/detail.html', {'question': question}) the user seems to be redirected to a 404 page no matter what id is passed in the url. -

How to add many objects to the database in Django TabularInLine?
Currently I have a need to add a lot of objects to a punch-through table using a python manage.py shell. I will describe the models here in a nutshell, I will not litter with unnecessary fields.

How can I override Django Model's save() method
I have a model which looks like this. import uuid from django.db import models class TemplateId(models.Model): id = models.SmallAutoField(primary_key=True, serialize=False, verbose_name='ID') template_name = models.CharField(max_length=255, default="") template_id = models.UUIDField(max_length=255, default=uuid.UUID, unique=True) def __str__(self): return str(self.template_name) class Meta: ordering = ('-id',) I have another function/code where I'm calling an API to fetch the template_name and template_id and store it in dB. But every time when I get a response from the API, I want to override the the whole table (everytime deleting old record and then adding the new records) currently I'm doing this: def fetch_template_id(): api_response = # calling the API for template_id in api_response: temp_name = template_id["name"] obj = TemplateId(template_id=template_id["id"], template_name=template_id["name"]) obj.save() In order to override, I tried overriding the save method in my TemplateId model as below but it didn't work def save(self, *args, **kwargs): super(TemplateId, self).save(*args, **kwargs) Since the data gets saved in the model fields by getting the API response, next time when same data is received from the API response, it throws an duplicate data error in the dB. How do I override all the every with each API call? -
Get notification on React-Native when app is closed (with websockets if possible)

Filter Queries which sum of their amount field are greater or lesser than a number

Django - Does Django know the number of instances of each model?
everybody. I was wondering... Since Django does not execute the query to the database until the Queryset is evaluated : QuerySets are lazy – the act of creating a QuerySet doesn’t involve any database activity. You can stack filters together all day long, and Django won’t actually run the query until the QuerySet is evaluated. Then how MODEL.objects.get(pk=1), for example, raises DoesNotExist exception when there is no MODEL instance with pk=1, even if I stored it in a variable without printing it for example ? -
conversion of python dictionary to json types in django rest framework
This is a question of comprehension rather than code issue. I am using DRF for a year. When I learnt about serializers, it says there are two steps. For get request what serializer class do is: Converting complex datatypes like queryset into python datatype like the dictionary. Converting dictionary into json format which is sent to the api as response. I use print commands to see everything what is happening or using the shell. I can see the first step happening ie I can see the complex queryset and after serialization can see the dictionary of the queryset. But nowhere in the code I can see the second step happening. Although the json format isnt very different from the python dictionary. The only difference I see is the double quotes instead of single quote in json. But still, the conversion needs to happen. Is it happening automatically or am I missing something here?? My snippet: My prints of the queryset and serialized data: Here, the email printed is the complex data. After serialization it is converted to python dictionary. However, the JSON data coming into postman is like this. -
How to distribute self-created ads onto the django project?

django autocomplete returning empty for linked data
In my django admin app, I have a Site table with references to Countries, and to specific Regions(provinces/states). Currently, when trying to add a Site entry, the dropdown menus for countries and regions display all possible objects.

For example, selecting Canada in the Country dropdown should result in only Canadian provinces being shown in the Region dropdown.
