Django: can I make db queries async?
In my app I have a template that I wish to make it like a control center that would display a ton of information, so I have to make a ton of queries to grab that info. So of course, the page is slow as heck and now I'm thinking how to fix this. I thought about making indexes but I don't have the space for this. I already optimized my queries to the minimun waste possible but it still takes like 1:30 minutes to load the page. I'm looking into assynchronous support on Django, but the version of Django I'm using doesn't seem to support (2.1). Does anybody got any tip that could help me in this? I didn't showed my code because I figured it's not nescessary, for this question is more abstract. It's not about my problem especifics but more about optimization in general. -
Django: make an addition inside of a model.objects.filter.update()
I have this view that has a form and I want to update a field of a model based on the user input. I cannot find a way to do that. The pytonic way =+ does not seem to work in this situation. Here is my view: def orders_on_the_way_edit2(request, Id): OnOrder2 = get_object_or_404(table_on_order, Id=Id) if request.method == 'POST': form = OnOrderUpdateForm(request.POST, instance = OnOrder2) if form.is_valid(): form.save() quantity = form.cleaned_data.get('Quantity_received') id = form.cleaned_data.get('Id') update2 = table_on_order.objects.filter(Id = Id).update(Quantity_received =+ quantity) update = table_on_order.objects.filter(Id = Id).update(StockOnOrder = (StockOnOrder - quantity)) messages.success(request, "Changed in order status successfully recorded") return redirect('OnOrder2') else: form = OnOrderUpdateForm(initial = { 'Id' : OnOrder2.Id, 'StockOnOrder' : OnOrder2.StockOnOrder, 'Quantity_received' : OnOrder2.Quantity_received, 'OrderCompleted' : OnOrder2.OrderCompleted}, instance =OnOrder2) return render(request, 'OnOrder2edit.html', {'form' : form}) the lines: update2 = table_on_order.objects.filter(Id = Id).update(Quantity_received =+ quantity) update = table_on_order.objects.filter(Id = Id).update(StockOnOrder = (StockOnOrder - quantity)) are causing the issue, update1 replaces the existing value by quantity and update2 gives me an error. Any clue on this would be appreciated! -
Django atomic transactions not actually atomic?

Django: Can't add field to custom user model
So, I've got a well running Django 3 app with a custom user model running on a MySQl db. I've been doing makemigrations and migrate successfully for months. Today I tried to add a field to my custom User Model called Account. The second I add a field to that model, the dev server attempts to process the change and crashes with this error: django.db.utils.OperationalError: (1054, "Unknown column 'account_account.lifetimeuser' in 'field list'") Doesn't matter the type of the field or the name. The base exception is: MySQLdb._exceptions.OperationalError: (1054, "Unknown column 'account_account.lifetimeuser' in 'field list'") Understand that this is NOT at runtime. It's right after I change the model and stop typing. Or in this case uncomment the lifetimeuser field (BTW, this is for testing only. I know I have an is_lifetime_user. That's the real field that was added sometime ago. Also note that this is ONLY with the Account model. Every other model in the file works as expected. Add, remove, edit: no problem as long as the syntax is correct. Since the error happens immediately, I can't makemigrations or migrate. I know my DB is in sync everywhere else. Can anyone give me a hint as to what is … -
Different One-To-Many relationships with same entities in Django
How would one go about implementing two different One-To-Many Relationships between the same entities in Django? For example: Suppose we have two relationships between a physical movement and muscles involved. For each movement I want to be able to distinguish between its main acting muscles and its supporting muscles. In practice I would introduce two tables (movement2primarymuscle, movement2supportingmucsle) and create a row with foreign keys for each relationship in each table. What's the Django way of implementing this with Django models? -

(Django) Can you access model methods in Create & List View?
I have a StaffProfile Model and an Establishment Model. I'm using Class Based Views, and in each of the CRUD views for the StaffProfile Model I need to check that the User logged in is an admin at the Establishment the StaffProfile is a member of. To do this I have a get_establishment() method in the views and a UserIsAdmin mixin that checks the User is an admin of the Establishment. My question is: instead of having to copy and paste the exact same method in each view, can I put it in the model itself and then reference it? I know I can for DetailView, UpdateView, DeleteView... but for CreateView and ListView it doesn't work as there is no object to reference, so I'm wondering if there is another way to access the method? Or a different approach I should be taking? My Code (shortened & simplified): views.py # URL for view is: <slug:establishment_slug>/staff/create/ class StaffProfileCreate(LoginRequiredMixin, UserIsAdminMixin, generic.CreateView): form_class = CustomStaffProfileCreationForm template_name = 'profiles/create_staffprofile.html' login_url = "login" def get_establishment(self): establishment_slug = escape(self.kwargs.get('slug')) establishment = Establishment.objects.get(slug=establishment_slug) return establishment # URL for view is: <slug:establishment_slug>/staff/<int:staff_pk>/ class StaffProfileDetail(LoginRequiredMixin, UserIsAdminMixin, generic.DetailView): model = StaffProfile template_name="profiles/detail_staffprofile.html" login_url = "login" def get_establishment(self): establishment_slug = escape(self.kwargs.get('slug')) … -
update a model in the view of a django restframework view
I can't find examples of using patch to update a partial view in rest framework and it isn't computing for me.

I just want to hit a view and have it update two fields. -
Django Paginator showing as disabled
I'm implementing a paginator in a blog section of a website, so that it only displays 6 items per page. Right now I have 7 items in the database, but it isn't displaying the paginator links as enabled, as if a second page didn't exist. The view: class PostListView(ListView): queryset = Post.published.all() context_object_name = 'posts' paginate_by = 6 template_name = 'blog/list.html' The template: <ul class="pagination"> {% if page.has_previous %} <li class="waves-effect"><a href="?page={{ page.previous_page_number }}"><i class="material-icons">chevron_left</i></a></li> {% else %} <li class="disabled"><a href="#!"><i class="material-icons">chevron_left</i></a></li> {% endif %} Page {{ page.number }} of {{ page.paginator.num_pages }} {% if page.has_next %} <li class="waves-effect"><a href="?page={{ page.next_page_number }}"><i class="material-icons">chevron_right</i></a></li> {% else %} <li class="disabled"><a href="#!"><i class="material-icons">chevron_right</i></a></li> {% endif %} </ul> And this is where I inserted the paginator object in the list template: <div class="col s12 m10 offset-m1 center"> <h1>blog</h1> <div class="row masonry-grid"> {% for post in posts %} <div class="col s12 m6 l4"> <div class="card fade-in-out up-in-out" data-duration="0"> <div class="card-image"> <a href="{{ post.get_absolute_url }}"><img src="http://placehold.it/600x400"></a> <span class="card-title">{{ post.title }}</span> </div> </div> </div> {% endfor %} </div> {% include 'pagination.html' with page=page_obj %} </div> So, the first page is displaying correctly, but the paginator isn't working and the second page (which should display, as I have … -
Django calls wrong function on given url

django.db.utils.OperationalError: duplicate column name: Email
I want to create a Django app that supports two different kinds of users. For that I have first extended my User by inheriting AbstractUser. Some fields are common to both the types of Users that I want my Django app to support and hence I add those fields in the extended User model.

Join 2 class in one query with common Foreign key
My model: class Doc(models.Model): numdoc = models.CharField(max_length=14) class DocQT(models.Model): doc = models.ForeignKey(Doc, models.DO_NOTHING, related_name='doc_qt') quantity = models.DecimalField(max_length=14) class DocDate(models.Model): doc = models.ForeignKey(Doc, models.DO_NOTHING, related_name='doc_date') date_cons = models.DateTimeField(defalt=date.today()) Now, i need to order by date_cons and get quantity using che common foreign key to join the classes. Something like: myquery= [...] for member in myquery: i need to render: member.quantity and member.date_cons
