Filter on nested serializer and Foreing Key Django/Rest Framework
Following are my model classes class ProductClass(models.Model): name = models.CharField('Name') class Product(models.Model): title = models.CharField('Product title') description = models.TextField('Description') product_class = models.ForeignKey(ProductClass, null=True, blank=True, related_name='products') class ProductPriceRepository(models.Model): product = models.ForeignKey(Product, related_name='price_repo') #: For a given entry we add maximum price of 99,999.99 unit. price = models.DecimalField('price of product', max_digits=7, decimal_places=2) is_default = models.BooleanField() This is how I have defined my view class ProductClassList(APIView): def get(self, request, format=None): product_classes = ProductClass.objects.filter(products__price_repo__is_default=True) serializer = ProductClassSerializer(product_classes, many=True) return Response(serializer.data) I have defined serializes as follow class ProductPriceRepositorySerializer(serializers.ModelSerializer): class Meta: model = ProductPriceRepository fields = ('price',) class ProductSerializer(serializers.ModelSerializer): price = SerializerMethodField() class Meta: model = Product fields = ('title', 'description', 'price') def get_price(self, obj): for price in obj.price_repo.all(): if price.is_default: serializer = ProductPriceRepositorySerializer(price) return serializer.data class ProductClassSerializer(serializers.ModelSerializer): products = SerializerMethodField() class Meta: model = ProductClass fields = ('name', 'products') def get_products(self, obj): for product in obj.products.all(): for price in product.price_repo.all(): if price.is_default: serializer = ProductSerializer(product) return serializer.data Output looks like [ { "name": "Product Class Test One", "products": { "title": "Test Product One", "description": "", "price": { "price": "100.00" } } }, { "name": "Product Class Test Two", "products": { "title": "Test Product Two", "description": "", "price": { "price": "30.00" } } } ] … -
Optimal SQL query for annotating materialized path descendents
Im currently using the django-treebeard library for its materialized path representation and helper functions, and running into an issue when trying to annotate the total number of descendents for each node in the tree. Namely, its slow. As you can see from the glaring inner query, i need to perform a count for each row of the outer to check for the children that share its path. My current solution is just staggering the queries by depth, so that the entire tree isn't ever queried, but that still leads to decent, however still noticeably slow performance on the front end as each time a node's children need to be displayed a query is required. I was curious if anybody else had run into this niche problem, or if anybody had any ideas as to how this could be further optimized. -- This query of 1000 takes around 45 seconds to complete... unusable at the use case of 40,000 SELECT "hierarchynode"."orphan", "hierarchynode"."path", "hierarchynode"."depth", "hierarchynode"."numchild", (SELECT count(*) FROM "hierarchynode" U0 WHERE U0."path"::text LIKE REPLACE(REPLACE(REPLACE(("hierarchynode"."path"), '\', '\\'), '%', '\%'), '_', '\_') || '%') AS "numdescendent" FROM "hierarchynode" WHERE ("hierarchynode"."broken_chain" = False AND "hierarchynode"."orphan" = False) LIMIT 1000 -
Django create new instances of a different model using the submitted form data of a model
I have a Topic model which has a ManyToManyField to the Tag model. Similarly to stack overflow where you can submit new tags at the time of asking a question. I want to be able to create new tags when you create a topic. A hacky solution from the top of my head. Class TopicCreateView(CreateView): # blah blah.... def form_valid(self, form): tags = self.request.POST.getlist(tags) for tag in tags: if not Tag.object.filter(tag_string__iexact=tag): try: new_tag = Tag.objects.create(tag_string=tag) except IntegrityError: # stuff I'm new to Django and web frameworks in general, but this seems really hacky to me (if it even works). Given what I've read so far regarding FormSets and such, is there not a better way to achieve this? -

I can not install django channels in a bunch the docker-compose
I faced with very enteresting error. I began to consider the django-chanels and can not start the chanels on docker-compose + gunicorn + nginx. My app is work fine, but channels is not run when start a server. For example: I is added 'channels' to INSTALLED_APPS and start my containers. When start server i must get error, since is missing this str: ASGI_APPLICATION = 'myapp.routing.application'. But error is missing. If I run server without docker, only with command: python manage.py runserver, then I get this error. I think on nginx or gunicorn.conf, but I do not understand how they can influence this. If need, this command is start my server: gunicorn --config app/gunicorn_config.py myapp.wsgi:application. Any idea? -

Django: Admin panel not showing all entries when using custom ModelAdmin class
I have a simple Django model class Tourney(models.Model): location = models.ForeignKey(Location, on_delete=models.CASCADE, verbose_name=_('Location'), related_name='tourneys') date = models.DateField(_('Date')) ... When I use this ModelAdmin class class TourneyAdmin(admin.ModelAdmin): list_display = ('id', 'date',) the admin panel shows every entry in the database. But when I include the location field like class TourneyAdmin(admin.ModelAdmin): list_display = ('id', 'date', 'location',) some entries are not shown in the list. On the bottom of the page the number of entries (x Tourneys) is still shown correctly. Any idea why that is happening?

Django - Pass value from pre_save to post_save methods on model
I've got a Django model like so... class Example(models.Model): title = models.CharField(...) ... I'm trying to compare two values - the title field before the user changes it, and the title after. I don't want to save both values in the database at one time (only need one title field), so I'd like to use pre_save and post_save methods to do this. Is it possible to get the title before the save, then hold this value to be passed into the post_save method? The pre_save and post_save methods look like so... @receiver(pre_save, sender=Example, uid='...') def compare_title_changes(sender, instance, **kwargs): # get the current title name here x = instance.title @receiver(post_save, sender=Example, uid='...') def compare_title_changes(sender, instance, **kwargs): # get the new title name here and compare the difference x = instance.title # <- new title if x == old_title_name: # <- this is currently undefined, but should be retrieved from the pre_save method somehow ...do some logic here... Any ideas would be greatly appreciated! -

Default NGINX Page On Everything But Last Server Name
I'm trying to connect my DigitalOcean Droplet to my custom domain. It's a Django website. The server_name will only go to the last thing in the list. So, if I have "server_name www.mydomain.com, mydomain.com" www.mydomain.com won't work (goes to the "Welcome to nginx!" page), but mydomain.com will. If I do the opposite, the opposite happens. What do I do for this? This is basically my "/etc/nginx/sites-available/myproject" as it stands: server { listen 80; server_name 142.93.58.126, mydomain.com; location = /favicon.ico { access_log off; log_not_found off; } location /static/ { root /root/myproject; } location / { include proxy_params; proxy_pass http://unix:/root/myproject/myproject.sock; } } The IP doesn't work, but the "mydomain.com" does because it's last. Any idea what might be going on here or how to see? I want to be able to have mydomain.com and www.mydomain.com work. -

This is my html file <!DOCTYPE html> <head> <meta charset="utf-8" /> <title>Cars</title> <h1> Enter sales data to store</h1> </head> <body> <div> <form method="post"> {% csrf_token %} <label for="billingnumber">Billing Number:</label> <input type="number" id="billingnumber" name="billingnumber"><br/> <label for="customername" >Customer Name :</label> <input type="text" id="customername" name="customername"><br/> <label for="purchasedate">Purchase Date:</label> <input type="date" id="purchasedate" name="purchasedate"><br/> <label for="price">Price:</label> <input type="number" id="price" name="price" ><br/> <label for="carcompany">Car Company:</label> <input type="text" id="carcompany" name="carcompany"><br/> <label for="carmodel">Car Model:</label> <input type="text" id="carmodel" name="carmodel"><br/> <label>Car Serial Number:</label> <input type="number" id="carserial" name="carserial"><br/> <label for="mfgdate">Car Manufacturing Date:</label> <input type="date" id="mfgdate" name="mfgdate"><br/> <label for="shippingdate">Shipping Date:</label> <input type="date" id="shippingdate" name="shippingdate"><br/> <button type="submit" value="submit">Submit</button> </form> </div> <a href="/">Home<a> </body> </html> This is my models.py class cars(models.Model): billingnumber = models.BigIntegerField(primary_key=True) customer = models.TextField() price = models.IntegerField() purchasedata = models.DateTimeField() carcompany = models.TextField() carmodel = models.TextField() carserialnumber = models.BigIntegerField() carmfgdate = models.DateTimeField() shippingdate = models.DateTimeField() These are my url patterns urlpatterns = [ url(r"^$", TemplateView.as_view(template_name="index.html"), name="home"), url(r"^store/$", TemplateView.as_view(template_name="store.html"), name="store"), url(r"^access/$", TemplateView.as_view(template_name="access.html"), name="access"), url(r"^about/$", TemplateView.as_view(template_name="about.html"), name="about"), ] I am unable to … -
django reverse url hitting another url
I have a base URL file that includes all apps URL files, and what I am trying to do is on click of Generate PDF Button, I want to hit an APIView / view-function passing a variable along as parameter via get method without encoding. HTML: <form onsubmit="{% url 'api-product:invoice-pdf-get' %}?R={{ variable }}"> <input type="submit" value="Generate PDF"> </form> Base URL path('api/product/', include(('store.urls', 'store'), namespace='api-product')), path('invoice/', InvoiceUrl.as_view(), name='print-invoice'), App URL: path('invoice-pdf-get/', invoice.InvoiceToPdf.as_view(), name='invoice-pdf-get'), On Click URL Generated: (Which is current, except with parameter) http://localhost:8000/invoice/? Can't understand why am I getting the same URL though when I inspect the HTML I see the URL included there, but without localhost:8000. There are several answers related to reverse URL on StackOverflow, none helped.
