Django filter and count in template tag
im trying to filter and count a specific queryset in the template with Django templete enginge. Cant get it to work. The film_list is the context and film is the table and language is a field. Any tips on how to use filter and count at the same time in the template engine? Or should i solve it in another way? {% if filmlist.film.language == "danish" %} {{ film_list.all.count }} {% endif %} -
django-rest-framework: how do I update a nested foreign key? My update method is not even called
I have something like this (I only included the relevant parts): class ImageSerializer(serializers.ModelSerializer): telescopes = TelescopeSerializer(many=True) def update(self, instance, validated_data): # In this method I would perform the update of the telescopes if needed. # The following line is not executed. return super().update(instance, validated_data) class Meta: model = Image fields = ('title', 'telescopes',) When I perform a GET, I get nested data just as I want, e.g.: { 'title': 'Some image', 'telescopes': [ 'id': 1, 'name': 'Foo' ] } Now, if I want to update this image, by changing the name but not the telescopes, I would PUT the following: { 'title': 'A new title', 'telescopes': [ 'id': 1, 'name': 'Foo' ] } It seems that django-rest-framework is not even calling my update method because the model validation fails (Telescope.name has a unique constraint), and django-rest-framework is validating it as if it wanted to create it? Things worked fine when I wasn't using a nested serializer, but just a PrimaryKeyRelatedField, but I do need the nested serializer for performance reason (to avoid too many API calls). Does anybody know what I'm missing? Thanks! -

django-channels identify client on reconnect
I connect several (anonymous, not logged in) clients via websocket / django-channels (routing.py, consumers.py). When a client reloads the page or reconnects, for whatever reason, he gets a new channel_name. Is there a nice way to identify the reconnecting client as the same client he was on first connect? Is there some kind of identifier? -

Django - Product Details in XML file
I have a task to export all product details such as name, price etc. from db to XML file. Since now i'm exporting most of the fields and save them to an XML file. However i'm a bit confused on how to export images. I have 2 models one for Product and one for ProductImages, see below: models.py class Product(models.Model): category = models.ForeignKey(Category, related_name='products', on_delete=models.CASCADE) name = models.CharField(max_length=50) slug = models.SlugField(max_length=500, null=True, unique=True) sku = models.CharField(max_length=100, unique=True) image = models.ImageField(upload_to='photos/%Y/%m/%d/') created_date = models.DateTimeField(auto_now_add=True) modified_date = models.DateTimeField(auto_now=True) class ProductImage(models.Model): product = models.ForeignKey(Product, related_name='images', on_delete=models.CASCADE) title = models.CharField(max_length=50, blank=True) image = models.ImageField(upload_to='photos/%Y/%m/%d/', blank=True, null=True) Also according to requirements there are two fields where images should be exported. If there is one image (product table) should be exported to item_image_link which i exporting it with no problem. And if there are more than one (ProductImage table) to item_additional_image_link and here is where i have issue. I iterate over products table like below and then trying to find all images for specific product id like: products = Product.objects.filter(product_status=True) images = ProductImage.objects.filter(product__id__in=products) for products in products: item = ET.SubElement(channel, "item") g_item_id = ET.SubElement(item, ("{http://base.google.com/ns/1.0}id")).text = products.sku g_item_image_link = ET.SubElement(item, ("{http://base.google.com/ns/1.0}image_link")).text = 'http://127.0.0.1:8000'+products.image.url for image in … -
Django admin create new entry in a different table from an existing entry
New to Django, and I am creating an API using the Django rest_framework. Mainly because I need the preconfigured admin panel. My problem is as follows. I have products and some are active on a site. Those products get inserted into a second table when they are rendered to the final user. So as soon as a product is available the admin inserts that new row to products_live table. My questions is as follows. Is it possible using the admin panel to tick a box in the products admin view and trigger the insert of the product from the product table to the products_live table while keeping the instance of the product in the product table? Hope I made my query clear. -

Django Rest Framework, How to update nested values in serializer

Update transactions on MasterSerializer. def create(self, validated_data): transactions = validated_data.pop('transactions') # for each transaction do Transaction Save() 2 . Somehow call the create mthoud of the TransactionItemSerializer within MasterSerializer create mthoud for each transaction i.e class TransactionsSerializer(serializers.Serializer): transactions = TransactionItemSerializer(many=True) class Meta: fields = ['transactions'] def create(self, validated_data): transactions = validated_data.pop('transactions') # call create on for each transaction TransactionItemSerializer.create() here -

How to store data on database after user login using social API, like facebook
I'm working on a react-native app using django as backend. The backend has a User table that extends AbstractBaseUser, and I want to store the data of social logged users inside this table. Now let's say I'm using facebook and google as social-auth API, when I get the data on the fronted, profile_id and email (for instance in the facebook case), what field do I have to use as password? I mean you'll say it's not necessary because the authentication occurs through the facebook server, but the "social_login/" endpoint is accessible without any permissions so anyone can make a request using facebook user email and its profile_id, as I saw it's possible to get it thought html inspector. So what do I have to use as unique and secure identifier when the user login-in using social API for the second time? Do I have to create a token/hash based on profile_id and email? Please don't suggest me django-social-auth or something similar, they don't fit my needs because of the high levels of customization I need. Thank you -

Broken pipe while parsing CSV file multiple times using pandas
I have a search bar which takes city name as input. A GET API is build on django, which takes the user input and search for the input in the CSV file. For example: If user types "mum".

Django: How to extract text from doc and docx files and then pass it to template to display it in a separate div that can be later on styled?
I am working on a Final Project for CS50W and I want a small app that allows users to upload their 'scripts' - files that are either .doc or .docx. These files are then saved in a separate folder and its url is saved in a models field. I want to create a separate view for displaying the contents of these files, that I can then later on style separately (changing background and text colors, size, etc.), so I want to extract the text from these files and pass it on to my template. But when I do that with open file function, I get FileNotFoundError - which I presume is because this file is not .txt file. What would be the best way to achieve this? Here's the relevant part of my code: class Script(models.Model): ... upload = models.FileField("Select your script", upload_to="scripts/%Y/%m/%D/", validators=[FileExtensionValidator(allowed_extensions=['doc', 'docx'])]) ... def read(request, script_id): script = Script.objects.get(pk=script_id) file = open(script.upload.url, 'r') content = file.read() file.close() return render(request, 'astator/read.html', { 'script':script, 'content':content, }) Maybe there's also a better way to achieve this with JS? Anyhow, thanks in advance for your help!
