Update Django context variable using Ajax
I've spent quite some time trying to find a solution, but I am fairly new to Django and I just can't seem to wrap my head around this. In my detail view I pass the product I want to display (product) in the template and also the first product type of the product (pid). When a new product type is selected via a dropdown box in detail.html, I need to update the product type context variable without reloading the page, and so that I can send it to cart_add view as a parameter in the URL. I figured I can do this using Ajax. I can display the value of the selected product type, but I do not know how to update the context variable to this new value. views.py def product_detail(request, id, slug): product = get_object_or_404(Product, id=id, slug=slug) product_types = ProductType.objects.filter(product=product, available=True) pid = product_types[0] mylist = [] for product_type in product_types: mylist.append(dict((x.base, x.value) for x in ProductAttribute.objects.filter(product_type=product_type))) category = Category.objects.get(id=product.category.id) parent_category = category.parent_category cart_product_form = CartAddProductForm() return render( request, 'shop/product/detail.html', {'parent_category':parent_category, 'category':category, 'product': product, 'cart_product_form': cart_product_form, 'product_types': product_types, 'mylist': mylist, 'pid':pid} def load_product_type(request): product_type_id = request.GET.get('product_type_pk') product_type = ProductType.objects.get(id=product_type_id) return render(request, 'shop/product/product-type.html', {'product_type': product_type}) product-type.html {{product_type.id}} detail.html <select … -

Form-data is send the same place independently of which url is parsed to action
I'm fairly new to Django, and I want to create a "delete user" button. I have the following: view.py @login_required def delete_profile_confirm(request): if request.method=="POST": request.user.delete() messages.success(request, "Profile has been removed!") return redirect("home_home") return render(request,"users/delete_profile_confirm.html") my urls urls.py urlpatterns= [. . path('', views.home,name="home_home"), path("delete_profile_confirm/",users_views.delete_profile_confirm,name="delete_profile_confirm") ] and my template delete_profile_confirm.html {% extends "my_app/base.html" %} {% block content %} <div class="content-section"> <form method="POST"> {% csrf_token %} <legend class="border-bottom mb-4">Are you sure you want to delete your profile?</legend> <form action="{% url 'home_home' %}" method="POST"> <input class="btn btn-default btn-danger" type="submit" value="Yes"/> </form> <a class = "btn btn-outline-info" href="{% url 'my_overview' %}"> Nopes - take me back!</a> </div> </form> </div> {% endblock content %} The funny thing is, that it works even though if I put anything in the <form action={url}> - It doesnt matter if it is home_home, delete_profile_confirm. In my understanding, it should be delete_profile_confirm since the post-request is handled there, but for some reason it works anyway. I might misunderstand what the action tag does exactly here? -
How to send multiplechoicesfield in post request - Postman

Django Model Attributes not obvious usage
class Invoice(models.Model): pass class Line(models.Model): cost = models.DecimalField(default=0.00, max_digits=9, decimal_places=2) I have two models. In Invoice model I need a total field everywhere(summary of lines cost). First I created a total attribute with a @cached_property that is obvious and clear way to define total of invoice. @cached_property def total(self): return self.line_set.aggregate(total_sum=Sum('cost'))['total_sum'] But after that, I realised that I can override Manager objects = InvoiceManager() class InvoiceManager(models.Manager.from_queryset(InvoiceQuerySet)): def get_queryset(self): return super(InvoiceManager, self).get_queryset().annotate( total=Sum('line__cost') ) and annotate this field in every query and remove total method! In this case total field is less obvious for programmers(IDE will not highlight it), but cost less resources if you will forget to use select_related What way is more preferable ? -
Override parent(some method of django faramework's class)'s global behavior by inheritance
In django/contrib/admin/sites.py, I have class AdminSite: def get_app_list(self): //do something pass def an_other_to_change(self): //do something pass def not_to_change(self): //do something pass I want to change/override implementation of few methods of this class so that default function should have some thing new in it what i want. To be sure that my code is working I added follwoing to end of a views.py file in my application. I also tried to add sites.py in my application and used the same following code, but its never executed because I am not calling it anywhere manually. What could be the way to achieve "default calls of django could come to these overridden methods rather than going directly to parent functions written in django/contrib/admin/sites.py" from django.contrib.admin.sites import AdminSite as BaseAdminSite # from django.contrib.admin import AdminSite as BaseAdminSite class AdminSite(BaseAdminSite): def _build_app_dict(self, request, label=None): res = super(AdminSite, self)._build_app_dict(request, label) res.update({'new_attr': 1}) return res def get_app_list(self, request): res = super(AdminSite, self).get_app_list(request) res.update({'new_attr': 1}) return res -
Chat with pusher and database
I'm building a real time chat using Pusher framework and since I want to keep the chat history and display it I am using also db storage. Having private-channels for each one-to-one conversation I'm not sure what is a recommanded way to deal with the database. My approach is like this: save new-message with post on "/conversation" having two user type foreign-keys in the database model: sender, receiver when I receive or send new-messages I get from "/conversations" the stored-messages filtered by (sender, receiver), add them to the current message on client-side and show them. Is there a better/optimized aproach to build or get the stored-messages and display them ? -

Not able to ignore static files from getting pushed to git in Django project
I had pushed a new Django project BTRE to my git repository. But I can't ignore the static files from pushed to the repository even though I have mentioned the directories in .gitignore file. -BTRE_Project |-btre |-static This is my .gitignore file: # If your build process includes running collectstatic, then you probably don't need or want to include staticfiles/ # in your Git repository. Update and uncomment the following line accordingly. btre/static/ I have tried deleting the repository and pushing again after updating the .gitignore file. -
django and django_plotly_dash integration with two databases vs one
I have integrated django_plotly_dash with my django app. It is a simple app that allows logging in and viewing some data and charts. Django is linked to MySQL database. The data for the plotly dash charts actually come from a second MySQL database. I use pymysql to query the data in the second database. It works as it is now. My question is if it is better to create django model and store the tables from the second database in the django database. Currently the second database just has some sample data so I don't mind loading data to either. The data will always be loaded into database through a python script, not from django front-end. What are the pros and cons in the two options - two databases vs one? Is there any impact on database connection when there are multiple users? -

Pythonanywhere static problems [closed]
Yesterday I upload at first time a Django App to pythonanywhere for check. After fighting me with the static URL, finally I could see the images and css on my computer, but only in Firefox. I open Chromiun and I can't see the styles. I try in other devices and the same result. Reading forums they speak about DNS, do you know why I can't see the static in others devices? Best Regards. -

django organize compliance check
Please tell me if there is an opportunity to check the compliance of the finished product with the client's requirements. There are three models: manufacturers Manufacturer Car - the characteristics of the cars they make through a one-to-many connection. and customer model with their own requirements for color and engine power I can't connect the customer with the Manufacturer and Car models.

How do I set DB name in AWS EC2 MySQL server?
So, I have created a database instance. I'm using Django, and tried to make proper changes in settings.py, as below DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME' : 'db-instance-bookcake', 'USER' : '', # my username 'PASSWORD' : '', # my pw 'HOST' : 'db-instance-bookcake.[therest]', 'PORT' : '3306', 'OPTIONS' : { 'init_command' : 'SET sql_mode="STRICT_TRANS_TABLES"' } } } Now I first thought that I needed to put the DB instance identifier in NAME. But then I realized that it's Database Name not Database Instance Identifier that's needed. So I looked for my DB name, but couldn't find it. I've tried modifying the DB instance, but all I could find was changing the DB instance identifier. How do I make change to, or set, the DB name, not DB identifier? Thank you very much in advance. -
