Django allauth OSError: [Errno 99] Address not available
I'm trying to implement django-allauth and faced this problem. For this project I'm using Docker as well. When I click "Sign up using VK" it redirects me to http://127.0.0.1:8000/accounts/vk/login/callback/?code=...random code... with this error. After going to sign up page again and clicking the same button it successfully redirects me to profile page which means the user was created. I couldn't find any solutions using Google so hope you can help. I don't think that was because of bad configuration because I've tested similar configuration on empty django project which was not containerized and everything worked properly. Maybe it's because inside docker container there's venv installed.

How to use multiprocessing in Python with Django to create thousands of model instances from xml file?
I have a script that parses data from an xml file into Django models. It works ok but recently we've been encountering files with dozen of thousands of models to create which is incredibly slowing down the process (up to 40 min to upload a single 20MB file). I would like to try and use multiprocessing to speed it up as much as I can but I am new to this package. This is the current setup: create_profiles_from_xml: is a function that loops through the data extracted from the xml, called xml_members, popping one element at a time (it has to be like that due to a relationship that can be created with the next element or not). create_profile: is a just a function that handles the data to match with the model fields and then call the .create() method, that's why I omitted the details of this function here. def create_profiles_from_xml(xml_members, device): profiles = [] while len(xml_members) > 0: parent_member = members.pop(0) profile = create_profile(parent_member, parent=None) if profile: profiles.append(profile) return profiles And here is what I tried to do with the multipocessing from multiprocessing import Pool def create_profiles_from_xml(xml_members, device): profiles = [] pool = Pool(processes=cpu_count()) profiles = pool.imap_unordered(create_profile, xml_members) … -

Set unique primary key based on foreignkey
I have a model defined as - class sales_order(models.Model): customer=models.ForeignKey() item=models.ForeignKey() branch=models.ForeignKey() --- ---other fields Now for each branch, I want to start the primary key from 1 ("id" for eg.), but the default functionality of Django will increment the id irrespective of any other data. I'm ok even if id keeps on incrementing as it does, and then I set my own field making it unique per branch and this field should auto increment without the user passing the data by checking the previous value from the database such as - class order_serializer(serializers.ModelSerializer): class Meta: validators = [ UniqueTogetherValidator( queryset=sales_order.objects.all(), fields=['myOwnDefinedField', 'branch'] ) ] I'm in a state of no idea how to achieve this. Using Django 3.1.5. Any help? -

Django : passing parameter or context with the function redirect and id encoded by hashids
I am a newbie and I need your help ! But maybe it's a complicated question even for experts, who knows! The following code works perfectly to generate a table (using a datepicker form to select the table's day) from the homepage, and with the ID page encoded with hashids in the URL, it redirects to the table URL generated for the day selected. For example, when a specific table is created for a particular day selected by the user, the page is redirected to http://127.0.0.1:8000/O3GWpmbk5ezJn4KR where "O3GWpmbk5ezJn4KR" is one table id encoded with hashids, this works fine. However, I would like to pass a variable with redirect(), the day selected in the datepicker used to create the table, in order to display the date on the html page rendered with the table generated. I tried the reverse function to pass the day variable with redirect, but if failed due to the hashid encoded URL not being recognized by the reverse function (example of error message obtained in the Shell : django.urls.exceptions.NoReverseMatch: Reverse for '/VvJ4openRe7Az1XP' not found. '/VvJ4openRe7Az1XP' is not a valid view function or pattern name.) Have you any idea to help ? Would appreciate any hint ! Best … -

RestAPI unable to download a file sent from Django API to sveltekit client - Fatal error reading a PNG image file
I have a Django Get APIView which returns a FileResponse with a png image data. When it is downloaded on the sveltekit client side then its not being read. It complains that it is not a png file.

Now here is the client side code: if (res.status == 200){ qrimage = await res.data; console.log(typeof(qrimage)); // const blob = new Blob(qrimage); // let url = window.URL.createObjectURL(blob); // let url = window.URL.createObjectURL(qrimage); let a = document.createElement("a"); // console.log(url); a.href = 'data:image/png;'+qrimage; a.target = '_blank'; a.download = 'qrcode.png'; a.click(); // }); } Thank you for help and comments. -

Many to many field reverse lookup with TreeQuerySet
I have made no leg way with my issue, I have tried following multiple tutorials but am getting no where. I have looked in these places (and elsewhere) - Django Model API reverse lookup of many to many relationship through intermediary table https://www.revsys.com/tidbits/tips-using-djangos-manytomanyfield/ https://docs.djangoproject.com/en/3.2/topics/db/examples/many_to_many/ https://readthedocs.org/projects/django-mptt/downloads/pdf/latest/ class CategoryTree(MPTTModel): title = models.CharField(max_length=120, default="no name") slug = models.SlugField(blank=True) timestamp = models.DateTimeField(auto_now_add=True) active = models.BooleanField(default=True) parent = TreeForeignKey('self', on_delete=models.CASCADE, null=True, blank=True, related_name='children') products = models.ManyToManyField(Product, blank=True) class MPTTMeta: order_insertion_by = ['title'] class Product(models.Model): title = models.CharField(max_length=120) slug = models.SlugField(blank=True, unique=True) description = models.TextField() price = models.DecimalField(decimal_places=2, max_digits=20, default=39.99) image = models.ImageField(upload_to=upload_image_path, null=True, blank=True) featured = models.BooleanField(default=False) active = models.BooleanField(default=True) timestamp = models.DateTimeField(auto_now_add=True) is_digital = models.BooleanField(default=False) # User Library Lets say in the Product models I have an item with the title Iron Man Toy, I need to find a way of finding the category (or categories) it belongs to in the CategoryTree model. I had one solution which came close to solving my problems but if the item was in two seperate categories, then I got an error message. -
Nginx not finding static files in Dockered Django app in Azure Web App for containers
I managed to run my Django app locally with docker compose( Django container + Nginx container) and it works fine, but when i want to run it in Azure web app for containers nginx can't find the ressources. I don't know if i should change some configuration so it can work in Azure services or i need to enable ports in azure app settings therefore my containers could communicate. This is my nginx configuration (nginx.conf) : upstream myapp { server web:8000; } server { listen 80; server_name myappname.azurewebsites.net; location / { proxy_pass http://myapp; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $host; proxy_redirect off; } location /static/ { alias /home/app/web/static/; } location /media/ { alias /home/app/web/media/; } } I don't know why it did work locally when i run docker compose but in azure web app nginx can't find static files. Please let me know if I need to clarify or include anything else. Thanks in advance.
