How to count total occurrence of distinct field of same model in django?
I am trying to get the total count of occurrence of a field in same model in django.

Decode resulting json and save into db - Django + Postgres
I have a model like this: class MyClass(models.Model): typea = models.CharField(max_length=128) typeb = models.CharField(max_length=128) If for example, the resulting json from an API is like this: { "count": 75, "results": [ { "typea": "This tipe", "typeb": "A B type", "jetsons": [], "data": [ "https://myurl.com/api/data/2/", ], "created": "2014-12-15T12:31:42.547000Z", "edited": "2017-04-19T10:56:06.685592Z", }, I need to parse this result and save typea and typeb into the database, I'm kind of confused on how to do this. I mean, there is the JSONField on Django, but I don't think that will work for me, since I need to save some specific nested string of the json dict. Any example or idea on how to achieve this? I mean, my confusion is on how to parse this and "extract" the data I need for my specific fields. Thank You -

I have gone through this link https://www.mattwoodward.com/2016/07/23/running-a-django-application-on-windows-server-2012-with-iis/ and followed it step by step. But when I hosted my Django app named 'sample', other apps that were hosted on the IIS started showing the below error while browsing and to mention other apps were developed in different frameworks. Error occurred while reading WSGI handler: Traceback (most recent call last): File "C:\virtualenvs\sample\Lib\site-packages\wfastcgi.py", line 791, in main env, handler = read_wsgi_handler(response.physical_path) File "C:\virtualenvs\sample\Lib\site-packages\wfastcgi.py", line 633, in read_wsgi_handler handler = get_wsgi_handler(os.getenv("WSGI_HANDLER")) File "C:\virtualenvs\sample\Lib\site-packages\wfastcgi.py", line 616, in get_wsgi_handler raise ValueError('"%s" could not be imported%s' % (handler_name, last_tb)) ValueError: "django.core.wsgi.get_wsgi_application()" could not be imported: Traceback (most recent call last): File "C:\virtualenvs\sample\Lib\site-packages\wfastcgi.py", line 605, in get_wsgi_handler handler = handler() File "C:\virtualenvs\sample\lib\site-packages\django\core\wsgi.py", line 12, in get_wsgi_application django.setup(set_prefix=False) File "C:\virtualenvs\sample\lib\site-packages\django\__init__.py", line 19, in setup configure_logging(settings.LOGGING_CONFIG, settings.LOGGING) File "C:\virtualenvs\sample\lib\site-packages\django\conf\__init__.py", line 57, in __getattr__ self._setup(name) File "C:\virtualenvs\sample\lib\site-packages\django\conf\__init__.py", line 44, in _setup self._wrapped = Settings(settings_module) File "C:\virtualenvs\sample\lib\site-packages\django\conf\__init__.py", line 107, in __init__ mod = importlib.import_module(self.SETTINGS_MODULE) File "C:\Python37-32\lib\importlib\__init__.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 1006, in _gcd_import File "<frozen importlib._bootstrap>", line 983, in _find_and_load File "<frozen importlib._bootstrap>", line 953, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 219, … -
I literally been stuck in this loop for days. edit/update can't detect the pk of the model?should i submit a ticket?
the error : .Reverse for 'patient_update' with keyword arguments '{'pk': ''}' not found. 1 pattern(s) tried: ['patients/update/(?P<pk>[0-9]+)$']? whenever i try calling the url in a template whether in action of a form tag or just a normal anchor. I made a view where users can edit the patients information and as I'm using a custom user model I had to make a custom update/delete view.The views are working when i enter them manually by the url but when i put a link reference to them by an anchor tag i get an error that it can't access the pk,I tried following many answers here and vids on YT but the error is still there Views.py def PatientUpdateView(request,pk=None): patient = get_object_or_404(models.Patient, pk=pk) form = forms.PatientForm(request.POST or None ,instance=patient) if form.is_valid() : patient = form.save(commit=False) patient.save() messages.success(request,"patient updated!") context = { 'patient': patient, 'form': form } return render(request,'patients/patient_edit_form_success.html',context) else: context = { 'patient' : patient, 'form': form, } return render(request, 'patients/patient_edit_form.html', context) and here's how i call it in an anchor tag <a class="btn btn-info btn-sm" href="{% url 'patients:patient_update' patient.pk %}">Open</a> I tried pk = patient.pk pk = pk pk={{ patient.pk}} and many other ways of calling it. urls.py here's the url … -
Drop Down group create and auto user add
The idea of my app is this. At the welcome screen the user has two options either register as a buyer or a seller. If the user decides to go for the simple buyer registration I'm going to use Django's built in sign up form for it but when the user signs up as a seller I want to create a group named "Owner" and their the user is automatically added and has a different dashboard according to their respective group. But this group gets created just once not on every view call. Please give me an idea to how can I achieve this. models.py # -*- coding: utf-8 -*- from __future__ import unicode_literals from django.contrib.auth.models import Group from django.db import models from cities_light import models as CityModel from phonenumber_field.modelfields import PhoneNumberField from django.contrib.auth.models import User class HallOwnerData(models.Model): owner_name = models.CharField( max_length=256) owner_address = models.CharField("Address",max_length = 256) owner_cnic = models.CharField("CNIC", max_length = 16) contact_number = PhoneNumberField() class HallProperties(models.Model): hall_name = models.CharField(max_length = 128) hall_city = models.ForeignKey(CityModel.City, max_length=512) hall = models.ForeignKey(HallOwnerData,on_delete = models.CASCADE) hall_address = models.CharField("Address", max_length = 128) hall_capacity = models.PositiveSmallIntegerField("Max Capacity") hall_number = PhoneNumberField() views.py # -*- coding: utf-8 -*- from __future__ import unicode_literals from django.http import HttpResponse from …
