Personalizations field error when sending multiple dynamic template emails in sendgrid
I'm trying to send a bulk email using Sendgrid Dynamic Templates in Django and getting this error: The personalizations field is required and must have at least one personalization.

django async/background for long running task
I have a django app with an endpoint that kicks off a long running task. I want to do this in the background. I know I could do this with celery or django-q, but I wanted to try something simpler first. First thing I tried was ajax. In the python code I did this: cookie = request.META.get('HTTP_COOKIE') csrf_cookie = request.META.get('CSRF_COOKIE') host = '{}://{}'.format(request.scheme, request.META['HTTP_HOST']) data = {...} resp = requests.post('{}/report/TASKS/Work/ajax/run.json'.format(host), headers={'COOKIE': cookie, 'X-CSRFToken': csrf_cookie, 'referer': host}, data=data) The function being called has the @login_required decorator, and when that runs it does the auth as the anonymous user, which fails so it redirects to the login page. The thread sending in the request is logged in and I have verified the cookies are all correct. Why would it use the anonymous user? How can I get it to auth using the logged in user? Tried something else next - instead of using ajax I call it with multiprocessing.Process. This fails because the thread does not have a database connection. Anyone have any thought on how I could make this work? -
Deploying Django API on Heroku- after changing DEBUG = False (in settings.py) and deploying my app, URLconf defined in URLS.PY are not listed
I have created Django API with three apps (users, task, house) with with help of routers show data in ViewSets. Some of these routers have to register multiple ViewSets. When testing endpoints both locally and on remote server (Heroku gunicorn) they are working. As app should be deployed in DEBUG=False mode, when I changed that in settings.py I came across a problem.! I changed DEBUG=False as expected to be on a live server. When I entred domain name generated by Heroku, I got message ::::: Not Found – The requested resource was not found on this server. I tried to enter endpoints manually (domain_name/endpoint) and it worked. Obviously I do not have anything under path(' ', include(...............)) as there is no priority for any of the three apps. I you have any idea/suggesting on how to get listed URLS admin/, api/ as on local server please let me know. Many thanks in advance. -

Django Python: Get the uploaded file name and add it to the body of the email message
This question is different than how to get uploaded file name in django as I need to add the file name to the body of the email message, and since all my email post and file upload code is in views.py, I'm not using a models.py file. How do I get the uploaded file name file and add it to the message part f'{form_data["message"]}' of the email? I'm not attaching the file to the email; I'm simply uploading it to the server via the forms.py. But I need to add the file name in the body of the email so I know which file has been uploaded by which email user. I am also aware that Django adds a random string of characters to the uploaded file name if it sees an existing file with the same name n the upload directory, so in that case, I need that file name included. Is that handled by file? views.py import smtplib from email.mime.multipart import MIMEMultipart from email.mime.text import MIMEText from django.shortcuts import render, get_object_or_404, redirect from django.core.files.storage import FileSystemStorage from contactform.forms import ContactForm from contact.settings import EMAIL_HOST_USER, EMAIL_PORT, EMAIL_HOST_PASSWORD, EMAIL_HOST def thanks(request): return render(request, 'thanks.html', {}) def contact(request): if request.method == … -

IntegrityError duplicate key value violates unique constraint
I found this solution on how to fix the problem I was running into: SELECT setval('tablename_id_seq', (SELECT MAX(id) FROM tablename)+1) but I am not familar with SQL statements so I don't understand what to replace the names with here. My table name is "student_course" so I assume that is what goes in tablename, but I do not understand what to do for the 'tablename_id_seq'. The error is occuring at "student_course_id_key", is that what I put for the id seq? -

how to pass context (placeholder in my case) to django admin Simple List filter
I am creating a college management system with facility to store quiz/tests in the website and get student performance. I wanted to filter quiz based on month year, such as show all quiz of march 2022.

Django : How write a decorator that takes an input after a redirect function
I want to write a decorator that takes an input coming from a redirect function (the value : id_contrat). If I explain a little bit more. An user selects a value in a form, then this value is redirect to another view "home". I want to check that the user has the rights on this value ! So I need to get it in my decorator. How do I add this value to my decorator. I tried something but it is not working : TypeError: wrapper_func() got an unexpected keyword argument 'id_contrat' My views : @authenticated_user def selectcontrat(request) : context = initialize_context(request) form_client = SelectClient(request.POST, user=request.user) if form_client.is_valid(): id_contrat = request.POST.get("ID_Customer") return redirect(reverse('home', args=(id_contrat,))) context['form_client'] = form_client return render(request, 'base/selectcontrat.html', context) @authenticated_user @check_user_rights def home(request, id_contrat=None): context = initialize_context(request) return render(request, 'home.html', context) the url definition : from django.urls import path from . import views urlpatterns = [ path('home/<int:id_contrat>/', views.home, name="home"), path('', views.loginAD, name="login"), path('signin', views.sign_in, name='signin'), path('callback', views.callback, name='callback'), path('selectcontrat', views.selectcontrat, name='selectcontrat') the form : class SelectClient(forms.Form): ID_Customer = forms.ChoiceField(label="Company :") def __init__(self, *args, **kwargs) : self.user = kwargs.pop('user') super(SelectClient, self).__init__(*args, **kwargs) id_client_list = AADJNTGroup.objects.filter(ID_User_id=self.user.id).values_list('ID_Group_id', flat=True) id_client_list = list(id_client_list) client_choices = Groups.objects.all().filter(ID__in=id_client_list).values_list('IDCustomer','GroupName') self.fields['ID_Customer'].choices = client_choices the decorator def check_user_rights(id_contrat) … -

Creating a shopping List in Django Admin
I am trying to show the shopping Cart for only a specific user in the Django Admin template . I managed to do it in a normal views like this : order = Order.objects.get(user=self.request.user, ordered=False) but when trying to do the same inside the model items = models.ManyToManyField(OrderItem.objects.get(user=settings.AUTH_USER_MODEL)) I get this error django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet. What I'm trying to achieve is to only show the items that the user entered to his shopping cart instead of all the order items in the system so is there a way to filter what is shown in the admin panel based on the user
