Redis becomes bottleneck when my app has high usage, but metrics seem normal
My project is using Django 3.2 with django-redis and is hosted on Heroku with the Redis Enterprise Cloud add-on for hosting Redis. I'm monitoring my app's performance with Sentry. Whenever my app has high usage, Sentry shows all interactions with Redis as taking a lot more time (could even be up to 10 seconds). The Redis add-on offers metrics and everything looks normal there; read/write latency is max 0.07ms. Adding more dynos (instances) relieves the issue, but I don't understand how all this is connected to Django doing Redis requests (e.g. adding celery tasks). Does anybody have an idea as to what might be going on? -
How to upload image file in post request in python?

Django/Celery: AttributeError when invoking task
I'm defining a Celery task to send bulk emails and am getting an unexpected error when invoking it with Celery.

Django static files load combined with css function url() generates weird & string in paths
I have deployed a django website to digital ocean, and storing static files into AWS buckets. So far so good, 'some' of my static files are loading correctly. For example, files like: <link rel="icon" href="{% static 'images/logo.svg' %}"> <script src="{% static 'js/jquery-3.3.1.slim.min.js' %}"></script> are loaded totally fine. The generated url when inspecting chrome's dev tools for, say the above logo is: https://<REGION>.digitaloceanspaces.com/<BUCKET NAME>/static/images/logo.svg?AWSAccessKeyId=<ACCESS KEY ID>&Signature=<AWS SECRET> which is correct, and the logo shows indeed on my webpage. Now, the weird thing is that I have some inline <style> blocks for which 'it nearly works'. Let me explain, I have the following piece in my html: <style> header#background-image { background-image: url("{% static 'images/header-background.svg' %}"); } </style> which is rendered as (again looking at chrome's dev tool): <style> header#background-image { background-image: url("https://<REGION>.digitaloceanspaces.com/<BUCKET NAME>/static/images/header-background.svg?AWSAccessKeyId=<ACCESS KEY ID>&amp;Signature=<AWS SECRET>&amp;Expires=1673362355"); } </style> The reason I mentioned this is 'nearly' ok is because I noticed the &amp; pieces of string in the generated url. If I correct those changing them to simple & and go to the modified link I indeed see my background image... This is so weird and drives me crazy, anybody got an idea of what is happening? -
Django custom auth backend not triggering when user does not exists
In Django==3.1.6, using a custom auth backend for insensitive login does not work properly. It only prints something when the user exists (lowercase). Whenever I enter a uppercase, it doesnt work and prints nothing.

How to filter an object with ManyToMany field?
I'm building a view where I add a product to a cart. To do this I create an instance of a CartItem model wich is related to a cart, a product and has variations (color, size...).

Django project working on IP address of droplet. But, it does not work on custom domain
I have my domain on GoDaddy and my hosting setup in DigitalOcean. So after I setup my basic django project, I used a droplet to deploy the code to an IP address. When I run this command, my project was running at my [IP_ADDRESS]:8000: gunicorn -w 2 -b 0.0.0.0:8000 --chdir /home/USER_NAME/projectdir/test_project test_project.wsgi Then, I put the three digital ocean nameservers in GoDaddy. I also modified the settings.py file by using the ALLOWED_HOSTS variables: ALLOWED_HOSTS = ['IP_ADDRESS', 'www.DOMAIN_NAME', 'DOMAIN_NAME'] My Nginx configuration looks something like this: server { listen 8000; listen 80; server_name IP_ADDRESS DOMAIN_NAME www.DOMAIN_NAME; location = /favicon.ico { access_log off; log_not_found off; } location /static/ { root /home/USER_NAME/projectdir; } location / { include proxy_params; proxy_pass http://unix:/run/gunicorn.sock; } } But still, I get 'This Site can't be reached'. I also checked that the nameservers have been updated by using https://lookup.icann.org/en. So I don't know where the problem lies. If you need any additional information let me know. Thank you -

Django - Prefill admin creation form with inline forms
I'm trying to create a form in Django admin, that, when you create a new entry, will take the latest entry, and fill the new entry with that data. E.g. (Book and Author are just examples) class Book(models.Model): id = models.Autofield(primary_key=True) author = models.ForeignKey(Author, on_delete=models.CASCADE) name = models.Charfield(max_length=200) class Author(models.Model): id = models.Autofield(primary_key=True) name = models.Charfield(max_length=200) I then added this to the admin page: class BookInline(StackedInline): model = Book extra = 0 class AuthorAdmin(ModelAdmin): inlines = [BookInline] admin.site.register(Author, AuthorAdmin) Now when I create a new Author, I want the form to be filled in with the last created author and his books So if said author had 5 books, it would now fill this form with the name of that author, and also add the 5 books. I was able to fill the author form by adding this to the AuthorAdmin class: def get_changeform_initial_data(self, request): return model_to_dict(Codebook.objects.all().get())#Temp But the books are not filled this way. Is it somehow possible, to pass the books into the inline forms? (Running Django 3.2 and Python 3.9) -
Correct way to add dynamic form fields to WagtailModelAdminForm
I have a use case where I need to add dynamic form fields to a WagtailModelAdminForm. With standard django I would normally just create a custom subclass and add the fields in the __init__ method of the form. In Wagtail, because the forms are built up with the edit_handlers, this becomes a nightmare to deal with. I have the following dynamic form: class ProductForm(WagtailAdminModelForm): class Meta: model = get_product_model() exclude = ['attributes', 'state', 'variant_of'] def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) if self.instance: self.inject_attribute_fields() def inject_attribute_fields(self): for k, attr in self.instance.attributes.items(): field_klass = None field_data = attr.get("input") field_args = { 'label': field_data['name'], 'help_text': field_data['help_text'], 'required': field_data['is_required'], 'initial': attr['value'], } if 'choices' in field_data: field_args['choices'] = ( (choice["id"], choice["value"]) for choice in field_data['choices'] ) if field_data['is_multi_choice']: field_klass = forms.MultipleChoiceField else: field_klass = forms.ChoiceField else: typ = field_data['attr_type'] if typ == 'text': field_klass = forms.CharField elif typ == 'textarea': field_klass = forms.CharField field_args['widget'] = forms.Textarea elif typ == 'bool': field_klass = forms.BooleanField elif typ == 'int': field_klass = forms.IntegerField elif typ == 'decimal': field_klass = forms.DecimalField elif typ == 'date': field_klass = forms.DateField field_args['widget'] = AdminDateInput elif typ == 'time': field_klass = forms.TimeField field_args['widget'] = AdminTimeInput elif typ == 'datetime': field_klass = forms.DateTimeField … -

Send data in a complete tree structure using django serializers
I have 2 models: Folder and Entity. class Folder(models.Model): name = models.CharField(max_length=255, null=False, blank=False) parent = models.ForeignKey('self', on_delete=models.SET_NULL, null=True, blank=True, related_name="child") class Entity(models.Model): name = models.CharField(max_length=255, null=False, blank=False) folder = models.ForeignKey('Folder', on_delete=models.SET_NULL, null=True, blank=True, related_name="entities") So a folder can have both child folders and entities. Now I want to send the data in a tree structure and I have written a serializer for it. class ListFolderSerializer(serializers.ModelSerializer): children = serializers.SerializerMethodField() class Meta: model = Folder fields = ['id', 'name', 'children'] def get_children(self, instance): child_folders = Folder.objects.filter(parent=instance).order_by("name") child_entities = Entity.objects.filter(folder=instance).order_by("name") all_children = [] if child_folders or child_entities: child_folders_data = ListFolderSerializer(child_folders, many=True).data child_entities_data = ListEntitySerializer(child_entities, many=True).data all_children.extend(child_folders_data) all_children.extend(child_entities_data) return all_children else: return None class ListEntitySerializer(serializers.ModelSerializer): class Meta: model = Entity fields = ['id', 'name'] This is working fine but as the data keep on increasing the time to get this tree is increasing.

Display records with respect to their id's in Django
My Django application includes a page named list in which list creates against a user to after analysis of .pcap file: The problem is I want to display the results on the basis of id in hash table. The id in hash_mod table has one to many relationships. Therefore, It'll be easy for me to fetch the results on the basis of id. How I will use the primary key (id in hash_mod) table to link through foreign key (hash_id in demo) table to fetch the results. I have also share the image url to view the list.html what it looks like. In list.html there is a button named "View" which is using the post method. There is for loop in list.html which recognize the total number of files analyzed by a user. When a user will analyze a file an id and hash will create in "hash_mod" table which I have mentioned below. Id will treat as a foreign key in another table, so I want to fetch the result witch respective to their primary key id and foreign key id. if anyone have still problem to understand the question anyone can ask.

This is my view: def edit_bendrija_view(request, bendrija_id): """ A view to edit Bendrijos name """ bendrija = get_object_or_404(Bendrija, id=bendrija_id) if request.method == 'POST': existing_bendrija = BendrijaForm(request.POST, instance=bendrija) if existing_bendrija.is_valid(): existing_bendrija.save() messages.success(request, "Your Bendrija Was Updated") return redirect(reverse('bendrijos')) else: messages.error(request, "Your Bendrija Was Not Updated") existing_bendrija = BendrijaForm(instance=bendrija) context = { 'existing_bendrija': existing_bendrija, "bendrija": bendrija, } return render(request, 'home/edit_bendrija.html', context) I am trying to edit an existing model using a form, the model only has 2 CharFields so its very simple, everything works up until I click the submit button, then the error that is the title comes up, and I am completely lost, especially because the error says the problem is on the "bendrija = get_object_or_404(Bendrija, id=bendrija_id)" line, this is the form if you are wondering: <form action="POST"> {% csrf_token %} <div class="row"> {{ existing_bendrija.name | as_crispy_field }} </div> <div class="row"> {{ existing_bendrija.address | as_crispy_field }} </div> <div> <p> <button type="submit" class="btn btn-success">Submit</button> </p> </div> </form> any suggestions? because I have 0 idea why the id is getting the request method and not the model id -
Pylint is not able to locate the model in the context of the views.py file
I'm using VSCode and the Pylint that ships with it, i.e., no extension. Everything has been running smooth for many months and I've never had an issue with Pylint presenting weird alerts. I recently started learning Django and today when following the official Django Documentation tutorial part 4 pylint could not recognize a couple of statements related to a model. Pylint can't recognize the (choice_set) method below selected_choice = question.choice_set.get(pk=request.POST['choice']) Pylint can't recognize (question.id) below return HttpResponseRedirect(reverse('polls:results', args=(question.id,))) The errors I get from pylint are below choice_set: Unknown Cannot access member "choice_set" for type "Question" Member "choice_set" is unknownPylancereportGeneralTypeIssues and id: Unknown Cannot access member "id" for type "Question" Member "id" is unknownPylancereportGeneralTypeIssues At first I thought the issue might've been I'd forgot to cross reference the Question and Choice models, but this is not the case. For reference, here are the related files for the project #models.py from django.db import models from django.utils import timezone import datetime class Question(models.Model): question_text = models.CharField(max_length=200) pub_date = models.DateTimeField('date published') def __str__(self): return self.question_text def was_published_recently(self): return self.pub_date >= timezone.now() - datetime.timedelta(days=1) class Choice(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) choice_text = models.CharField(max_length=200) votes = models.IntegerField(default=0) def __str__(self): return self.choice_text #views.py from .models import Choice, … -
