How to handle 302 in django 2.2?
I have 3 or more items in my order summary page. When I remove one of the items, my code redirects me to the same order summary page. But when I am trying to remove last order from the order summary page, my code redirects me to the home page. I want to stay on the same page while the cart is empty with continue shopping button but when I removed the last item from the cart it redirects me back to home page views.py def remove_from_cart(request, slug): course = get_object_or_404(Course, slug=slug) cart_qs = Cart.objects.filter(item=course, user=request.user) if cart_qs.exists(): # cart = cart_qs[0] # if cart.quantity > 1: # cart.quantity -= 1 # cart.save() # else: cart_qs.delete() order_qs = Order.objects.filter( user=request.user, ordered=False ) if order_qs.exists(): order = order_qs[0] # check if the order item is in the order if order.orderitems.filter(item__slug=course.slug).exists(): order_item = Cart.objects.filter( course=course, user=request.user, )[0] order.orderitems.remove(order_item) messages.info(request, "This item was removed from your cart.") return redirect("cart:order-summary") else: messages.info(request, "This item was not in your cart") return redirect("cart:order-summary") else: messages.info(request, "You do not have an active order") return redirect("cart:order-summary") order-summary.html <tbody> {% if carts %} {% for cart in carts %} <tr> <td> <p>{{ cart.item }}</p> </td> <td> <p>Rs. {{ cart.price … -

Django: Making additional REST call inside View when handling user's form
What do I have: One Django form with a set of fields users can populate and send. When I handle form fields into View Class one additional Http request should be executed (to external Rest service) to check the user's address and add coordinates. So in plain Python this may be done with import requests requests.get() How this case should be implemented in Django? -
Django : 'tag' is not a registered tag library error
I'm having this error when loading a custom tag in my template.

Django Project with database settings configured through environment variables - migrations work but when I run server it uses empty database
I've configured on Ubuntu using virtual enviroment. I configured my database settings using settings.py file and specifying environment variables there (os.environ['DATABASE_NAME'] and so on). Interestingly I can now work with migrations using manage.py migrate commands and projects gets deployed on AWS Elastic Beanstalk with these settings and work there (I defined variables with the same values on that side), my problem now is the following: - If I run server locally using manage.py it starts without any errors but looks like it works with empty database and I'm not sure how I check which one - but no data I've added on the live one running on AWS - At the same time if I deploy using eb deploy I see that all works fine and my migrations applied and data is available I just don't understand which database is being used when I run my Django server locally - settings.py only contains variables defining connection to RDS instance and SQLite file deleted. -

Why is Django adding "/accounts/logout/" to all {% url %} template tag lookups?
I have a very simple POC template, in Django, contains this; <form action="{% url 'formtest' %}" method="post"> {% csrf_token %} {% url 'formtest' %} <input type="submit" value="Vote"> </form> When I render it, the URL template tags makes my target this; /accounts/logout/formtest That isn't right, it should be just '/formtest'. And I can't figure out why it's prepending that /accounts/logout bit. The user is not logged in. And my url.py looks like this; urlpatterns = [ path('', views.index, name='index'), path('create_user/<str:username>', views.create_user, name='create_user'), path('monitor', views.monitor, name='monitor'), path('upload', views.upload_file, name='upload'), path('formtest', views.formtest, name='formtest'), ] My Django version is 2.2.5 and I've tried witling down the example to the almost bare minimum. But I can't find why that template tag is adding that bit. I am almost positive something weird or strange has been done by myself, but I failed to find what and where. -

Cache update in a many 2 many relation
I'm using a combination of Django, GraphQL (graphene-django), VueJS and Apollo Client for my project. Everything is working fine until I tried to manage many2many relations. Usually when I make an update mutation to an object that is already in the cache, it is detected and the data that is displayed is updated. The problem is that in my new case, I'm updating the many2many relation between my two objects and it doesn't update, while it is correctly done in database (and even in cache, when I print it in the console, which is weird). Typically, I'm trying to add/remove users in/from a group. Maybe I've been watching my code for a too long period and I can't see something obvious.. Anyway here is my code : My Django models : class Group(models.Model): def _get_users_count(self): return self.user_ids.count() name = models.CharField(max_length=255) user_ids = models.ManyToManyField(User, related_name="group_ids", db_table="base_group_user") users_count = property(fget=_get_users_count, doc="type: Integer") def __str__(self): return self.name class User(AbstractUser): def _get_full_name(self): return "%s %s" % (self.first_name, self.last_name.upper()) full_name = property(fget=_get_full_name, doc="type: String") def __str__(self): return self.full_name def _has_group(self, group_name): return self.group_ids.filter(name=group_name).exists() My schemas : class GroupType(DjangoObjectType): class Meta: model = Group fields = ('id', 'name', 'user_ids',) users_count = graphene.Int() class UserType(DjangoObjectType): class Meta: … -
Id serialization does not update when I create objects using shell in Django PostgreSQL
I have a module called shell_functions where I have the following function: def add_areas(): for data in some_data: Area.objects.create(id=data['id'], name=data['name']) I run this function from the shell to create objects. After this, I tried creating an Area from the admin panel. However, this time I get an integrity error saying the Area with the id=1 already exists. Obviously, the id serialization counter did not update itself as I explicitly put in the id in the shell function. How to solve this issue? Thanks for any help!
