Why are files uploaded from phone processed slower then files uploaded from pc on a webpage by django/nginx?
I have a webpage running on django+gunicorn+nginx, it has a file input and a post button.

Page not found error while deploying django app on centos7 using nginx and uwsgi
I'm trying to deploy my django app on a centOS7 server using VPS with nginx and uwsgi, following this tutorial https://www.youtube.com/watch?v=c_17jALtLbQ&feature=youtu.be. The server is up and running i.e., the homepage (welcome to nginx) is working but when I navigate to a different page it tells me "page not found". Previously, I also tried using Apache following this https://www.digitalocean.com/community/tutorials/how-to-serve-django-applications-with-apache-and-mod_wsgi-on-centos-7.

Dynamic updates in real time to a django template
I'm building a django app that will provide real time data. I'm fairly new to Django, and now i'm focusing on how to update my data in real time, without having to reload the whole page. Some clarification: the real time data should be update regularly, not only through a user input. View def home(request): symbol = "BTCUSDT" tst = client.get_ticker(symbol=symbol) test = tst['lastPrice'] context={"test":test} return render(request, "main/home.html", context ) Template <h3> var: {{test}} </h3> I already asked this question, but i'm having some doubts: I've been told to use Ajax, and that's ok, but is Ajax good for this case, where i will have a page loaded with data updated in real time every x seconds? I have also been told to use DRF (Django Rest Framework). I've been digging through it a lot, but what it's not clear to me is how does it work with this particular case. -

Django + Docker best practice: use runserver or wsgi.py?
I've been reading a lot of blog posts (like this one) on how to deploy Django in a containerized Docker environment. They all use the runserver command in the docker-compose.yml. Even the Docker documentation does this. This suprises me, since using the Django web server is not recommended for production! What is recommended is pointing the webserver to wsgi.py. However, none of the articles I've found on Django and Docker explain why they use runserver instead of pointing apache or nginx to wsgi.py. Why would all these articles use the built-in Django development webserver to handle requests, instead of a full blown webserver like apache or nginx? Isn't the point of using containers in development, to keep that environment as close to production as possible? Then why build a not-production-ready environment? -

Is there any way to make the wagtail body field readonly?
I have a question. I'm developing blog app with wagtail. main point about blog page: Writer can write "title", "introduction" and "body". Firstly, writer can submit title. After finishing "title task", writer can edit and submit body. When writer do title task, writer can not edit body field. Furthermore, when writer do body task, writer can not edit title field. I want to Change permission dynamicaly for titleField and bodyField(RichTextField) but I could not figure out how to its. I thought editting hook about "@hooks.register("after_edit_page")" in wagtail_hooks.py can reach resolving. I tried to use PagePermissionHelper, PermissionHelper. thank you -

Mod_wsgi doesn't load page on Apache server

Allowing other characters than numbers in a form for a BigIntegerField
I'm trying to allow users to enter other characters than numbers in a form that has a BigIntegerField. The numbers can be very large, such as 149648594350 / 149.648.594.350 and to avoid mistakes in the input I want to allow "separators" in the input. My idea was to change the input to a TextInput and then create a Form that cleans the input and strips everything but numbers in the cleaned data. This is the code I have: class Score(models.Model): score = models.BigIntegerField(null=False, blank=False) game = models.ForeignKey(Game, null=False, blank=False, on_delete=models.PROTECT) player = models.ForeignKey(Player, null=False, blank=False, on_delete=models.PROTECT) class ScoreForm(ModelForm): def clean_score(self): print("CLEANING SCORE") class Meta: model = Score fields = '__all__' class ScoreCreateView(CreateView): template_name = "register_score.html" success_url = reverse_lazy('registered_score') model = Score form_class = ScoreForm def get_form(self, form_class=None): form = super().get_form(form_class) form.fields["score"].widget = TextInput() return form However, there seems to be some early validation of the input that ends up giving me a "Enter a whole number."-error and clean_score isn't running. Any ideas how to get around this, or to do it a completely different way? Thanks for any help. -
DRF - a better way to write double nested serializers
I am building a todo app that can have comments posted on to the todo. For that to work, I have made a writable double nested serializer. It works, but the update method I have written is difficult to understand, and so I am trying to make it more readable. Is there a better(or standard way) to write an update method for a double nested serializer? I have read the docs for nested serializers in the official documents. https://www.django-rest-framework.org/api-guide/serializers/ models.py class CustomUser(AbstractUser): def __str__(self): return self.email class Todo(models.Model): publisher = models.ForeignKey( CustomUser, on_delete=models.CASCADE, related_name="todos", ) title = models.CharField(max_length=50) pub_date = models.DateTimeField('date published') description = models.CharField(max_length=800) is_done = models.BooleanField(default=False) def __str__(self): return self.title class Comment(models.Model): subject = models.ForeignKey( Todo, on_delete=models.CASCADE, related_name="comments", ) publisher = models.ForeignKey(CustomUser, on_delete=models.CASCADE) title = models.CharField(max_length=50, default=None) pub_date = models.DateTimeField('date published') description = models.CharField(max_length=800) def __str__(self): return self.description serializers.py class CommentSerializer(serializers.ModelSerializer): class Meta: model = Comment fields = ( 'url', 'title', 'pub_date', 'description', ) read_only_fields = ( 'url', 'pub_date', ) class TodoSerializer(serializers.ModelSerializer): comments = CommentSerializer(required=False, many=True) class Meta: model = Todo fields = ( 'url', 'title', 'pub_date', 'description', 'is_done', 'comments' ) read_only_fields = ( 'url', 'pub_date', ) class UserSerializer(serializers.ModelSerializer): todos = TodoSerializer(required=False, many=True) class Meta: model = CustomUser … -
Django field model for HTML parser?
The contents of my models.py looks like this: from django.db import models # Create your models here. class Post(models.Model): title = models.CharField(max_length=256) pub_date = models.DateTimeField() image = models.ImageField(upload_to='media/') body = models.TextField() def __str__(self): return self.title def pub_date_pretty(self): return self.pub_date.strftime('%A %d %B %Y @ %-I:%M:%S %p') def summary(self): return self.body[:350] Lines 5 through 8 initiate the model class variables for my blog dashboard. My dashboard looks like this. There is a title, pub date, image and body. The Udemy instructor suggests consulting the official Django doc for field types/options. I’m not sure I really understand most of it. There is just so much information there. My question for all of you: Which field option or field type initiates an HTML parser for body text? I mean, when I go to to create a new blog post, how do I create rich text with HTML formatting buttons like bold, underline and italics? It’s not really the buttons I care about. I just want my HTML tags to parse. Take note of the HTML tags I’ve circled in red here. How do I get the h5, hr and em to parse? Is there a field option/type for this? I don’t see it in … -

how to login a Custom User Model in django rest API framework
I defined a Custom User Model in models.py whose name is Student. This model inherits Django User. I can sign up student correctly, but when I want to login , I get error.

Combining django queryset objects having similar values
It's an eCom site that I am working on. I need to filter results based on email, as in obtain all those orders placed by this email account. On executing the query OrderItem.objects.filter(order__email='john@john.com').select_related('order') I get queryset object for each product. So if an order had multiple products then each product is a set on it's own. What I need is all items combined in the one set for an order ID so that I can iterate through them in the template. OrderItem.objects.filter(order__email='john@john.com').select_related('order').values('order_id').annotate(ct=Count('pk')) - This query gets all those IDs and shows how many sets are there per ID. Likewise I just need the results but with other fields like created_date, order_id, transaction_id, product. I have explored the django documentation but don't seem to find an appropriate solution. Another option is to manually loop through each item in the queryset and segregate based on the order_id having multiple items but then again that doesn't seem efficient. So any thoughts on how to proceed would be great. Models are below: class Order(models.Model): payment_date = models.DateTimeField(blank=True, null=True) created_date = models.DateTimeField(auto_now_add=True) transaction_id = models.CharField(max_length=256, blank=True, null=True) email = models.EmailField(max_length=128, blank=True, null=True) def __str__(self): return "Order #{},Date:{}".format(self.id,self.created_date) class OrderItem(models.Model): product = models.ForeignKey(PRODUCT_VARIANT_MODEL, on_delete=models.DO_NOTHING) quantity = …
