Best way to log, then send single email using Django Mailer?

Also, wondering if there's a way to implement this using the email_message object. Thank you. -

Optional parameters passed in a Django URL
Sorry if this is complete noob question, I just can't seem to get a straight answer with this very simple concept. In Django (Django Rest Framework actually, but I assume it would be the same), how do I pass optional parameters in the URL? Based on all the info I could gather, I have a urls.py that goes like this: # urls.py from .views import (HistoryIndex, from django.urls import re_path urlpatterns = [ re_path(r'^history/(?P<limit>)/$', HistoryIndex.as_view(), name='history_index'), ] The idea is to pass in a optional parameter (using the ? & syntax), limit, to limit the results passed back: # views.py from rest_framework.views import APIView from rest_framework.response import Response from .models import EventHistory from .serializers import class HistoryIndex(APIView): def get(self, request, **kwargs): user = request.user limit = int(kwargs['limit']) histories = EventHistory.objects.filter(user=user).order_by('-updated_at')[:limit] history_index = [ HistorySerializer(history).data for history in histories ] return Response(history_index) I'd like to be able to hit the endpoint like so: http://localhost:8000/history/ or http://localhost:8000/history/?limit=10 but I can't even get as far as my view. The django browsable API shows a 404, but in its list of possible endpoints, it includes ... ^history/(?P<pk>[\w-]+)/$ [name='history_index'] ... as an available endpoint. What am I missing?

Django project doesn't 'see' Python modules installed with Pipenv

I'm creating a simpel website in Django (latest) that does the following: In the admin panel I can create a company and a team, there's a third model that contains the forms. In models.py: class Company(models.Model): companyId = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) companyname = models.CharField(max_length=254) ....some other fields.... class Team(models.Model): teamId = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) teamname = models.CharField(max_length=254) company = models.ForeignKey(Company, related_name='teams', on_delete=models.CASCADE) ....some other fields.... class UserForm(models.Model): UserForm_id = models.AutoField(primary_key=True) UserForm_company = models.ForeignKey(Bedrijf, related_name='UserForm_company', on_delete=models.CASCADE, null=False) UserForm_team = models.ForeignKey(Team, related_name='UserForm_team', on_delete=models.CASCADE, null=False) ....some other fields.... In views.py: class UserFormCreateView(CreateView): context_object_name = 'form_UserForm' form_class = UserFormName template_name = 'app/form.html' success_url = reverse_lazy('') #leads to index.html model = models.UserForm In the urlpatterns (urls.py) I include the following: (I have included the slugs in my models and views) urlpatterns = [ ..... path('<slug:urlCompany>/<slug:urlTeam>/<slug:urlForms>', views.UserFormCreateView.as_view(), name='UserForm'), ] Individual members are not registered. I just have multiple companies and each can have multiple teams. Teams would navigate to a url similar to: app/1239a36e-9694-42c3-a6f8-e058db218feb/b28819e0-5d97-4c3f-97aa-9d6cb55a0b07/userform which corresponds with app/urlCompany/urlTeam/urlForm So far so good. What I would like to have is that when the form is submitted, the companyname and teamname is included automatically. When I test the form, these fields (in the adminpanel) remain empty. Is there … -
Cart transfer between sites [closed]
Python/Django: Im trying to build something that would allow a user to make a cart on my site and then redirect that user to the e-commerce site where the basket is from. My problem is that I dont know how to transfer the whole basket to the e-commerce site. Could you please let me know what do you think? ( also the e-commerce site in question does not have an API, or an affiliate program I can work with )Thank you !
