views.py not working and member is not removed, interest not removed too
Ok in my project, every blogpost has their own group of members. You are only a member if your interest status is 'Accepted', and you get auto added to the member list. Every user can "submit interest" to any blogpost. In case you are confused, the members is a field of BlogPost model, and the status is a field in the InterestInvite model :) I am trying to make it such that when I press the 'remove member' button, they get removed from the member list, and also the initial interest that they have submitted would be removed. Which means members that are removed can submit interest again. There are 2 views, the first view is the functionality for the blog post author to be able to remove ANY member from the members list, the second view is the functionality for any of the members to be able to remove THEMSELVES from the members list. Can any kind soul help to see why my views aren't working models.py class Account(AbstractBaseUser): email = models.EmailField(verbose_name="email", max_length=60, unique=True) username = models.CharField(max_length=30, unique=True) class BlogPost(models.Model): title = models.CharField(max_length=50, null=False, blank=False, unique=True) author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) slug = models.SlugField(blank=True, unique=True) members = models.ManyToManyField(settings.AUTH_USER_MODEL, blank=True, related_name="members") … -

And when I click on the title, I will be directed to that particular blog post. Can anyone share how this querying can be done? Problem i am facing is that i cannot use … -
Django object.raw('query') doesnot return updated queryset
class view_name(viewsets.ModelViewSet): queryset = model_name.objects.raw('call stored_procedure();') serializer_class = model_name_Serializers permission_classes = [IsAuthenticated] So, when I execute the above the rest framework view set. It works fine. But when I update any value which will effect the queryset of the stored procedure. It still return the previous queryset not the updated one.

Django ORM queryset equivalent to group by year-month?
I have an Django app and need some datavisualization and I am blocked with ORM. I have a models Orders with a field created_at and I want to present data with a diagram bar (number / year-month) in a dashboard template. So I need to aggregate/annotate data from my model but did find a complete solution. I find partial answer with TruncMonth and read about serializers but wonder if there is a simpliest solution with Django ORM possibilities... In Postgresql it would be: SELECT date_trunc('month',created_at), count(order_id) FROM "Orders" GROUP BY date_trunc('month',created_at) ORDER BY date_trunc('month',created_at); "2021-01-01 00:00:00+01" "2" "2021-02-01 00:00:00+01" "3" "2021-03-01 00:00:00+01" "3" ... example 1 "2021-01-04 07:42:03+01" 2 "2021-01-24 13:59:44+01" 3 "2021-02-06 03:29:11+01" 4 "2021-02-06 08:21:15+01" 5 "2021-02-13 10:38:36+01" 6 "2021-03-01 12:52:22+01" 7 "2021-03-06 08:04:28+01" 8 "2021-03-11 16:58:56+01" 9 "2022-03-25 21:40:10+01" 10 "2022-04-04 02:12:29+02" 11 "2022-04-13 08:24:23+02" 12 "2022-05-08 06:48:25+02" 13 "2022-05-19 15:40:12+02" 14 "2022-06-01 11:29:36+02" 15 "2022-06-05 02:15:05+02" 16 "2022-06-05 03:08:22+02" expected result [ { "year-month": "2021-01", "number" : 2 }, { "year-month": "2021-03", "number" : 3 }, { "year-month": "2021-03", "number" : 3 }, { "year-month": "2021-03", "number" : 1 }, { "year-month": "2021-04", "number" : 2 }, { "year-month": "2021-05", "number" : 3 }, { "year-month": … -

Django can you give the same user 2 usernames(with "profiles")?
I'm working on a system where the same user might have 2 profiles (ex one as an employee and one as his personal profile) and I want him to access diff parts of the app based on his profile, can he get 2 usernames and get diff permissions based on the username he signed in with? Thought of making a profile model which has a user type and a foreign key to user and then make user type and user unique together so that the user could have multiple profiles but not of the same time. and then make the username on the profile and then keep the profile in the request instead of the user, but that is making a lot of issues, one is that Django doesn't allow having no username field on the user model, so does anyone know any workaround? Or the only way is giving him multiple users??? Please I need a fast answer.... -

axios shows CORS error, with django rest framework
Thanks for reading. I am working with vuejs SPA with flask and django backends. Yes there are 2 backends. The application is in transition. I am switching the back end from Flask to Django Rest Framework. Some parts are still with Flask. Problem axios POST request does not hit django server. The error in console shows as a CORS error. Same calls worked with flask-restful and flask-CORS. GET request works fine with Django Relevant code BACKEND settings.py ... INSTALLED_APPS = [ ... 'rest_framework', 'corsheaders' ... ] MIDDLEWARE = [ ...

Adding json data works normally in django-admin dashboard, django_rest_framework API interface and in httpie command line client So it appears the issue is with axios. I have tried headers: { 'Content-Type': 'application/json', 'Access-Control-Allow-Origin' : '*', 'Content-Type': 'application/x-www-form-urlencoded' } Above have been tried separately I have also … -

In my app there are several if conditions. In one of the if condition a modal with two buttons will be shown. if the user clicks one button it should go execute a statement. If user clicks another one it should execute another statement. Is it possible in django.
