Django makemessages on third-party iframe?
I'm using a third-party library, and I'd like to translate the text on some of the iframes provided by the library on my website. I can't use makemessages to generate the correct phrases in the .po files, as the iframe code is not part of my codebase. I could manually add the translations to the .po files but then the next time I run makemessages these phrases will be removed because i18n will not find them within the codebase. Is there a way to use i18n on the words of a third-party iframe without the translations being removed every time makemessages is run? -

Error when trying to serialize multiple followers:Got AttributeError when attempting to get a value for field `email` on serializer `UserSerializer`
I am trying to show the followers in UserSerializer,as a user instance.Almost the same method i used in article model works,but in user model it gives me problem.Below i can explain it better with my codes: Models.py class User(AbstractUser,PermissionsMixin): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) email = models.CharField(max_length=255,unique=True) username =models.CharField(max_length=80,unique=True,default='SOME STRING') class Article(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) author = models.ForeignKey(User,on_delete=models.CASCADE,related_name='articles') caption = models.CharField(max_length=250) class FollowUserModel(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) author = models.ForeignKey(User,on_delete=models.CASCADE,related_name='followers') profile = models.ForeignKey(User,on_delete=models.CASCADE,null=True) created = models.DateTimeField(auto_now=True) Serializers.py class UserSerializer(serializers.ModelSerializer): followers_set = serializers.SerializerMethodField() def get_followers_set(self, user): return UserSerializer(user.followers.all(), source='followers', required=False,read_only=True,many=True).data class Meta: model = User fields = ('id','email','username','followers_set') class ArticleViewSerializer(serializers.ModelSerializer): author = UserSerializer(required=False,read_only=True) class Meta: model = Article fields = ('id','author') def create(self, validated_data): return Article.objects.create(**validated_data) class FollowSerializer(serializers.ModelSerializer): author = UserSerializer(required=False) profile = UserSerializer(required=False) class Meta: model = FollowUserModel fields = ("author","profile") Now the author works as intended,it gives the full user instance.But in followers_set i get this error: Got AttributeError when attempting to get a value for field `email` on serializer `UserSerializer`.

Save a unique order id for each company in django
I would like to have a unique id_order per company, and if already exist, i cannot save the order or form is not valid. In my example, each company save orders, Company A can save id_order 1 id_order 2 id_order 3 ...

Django - how to obtain the latest related model in an efficent way I can iterate on the template?
Let's say I have two related models, one of the two with a datetime field. (Author & Book with a pub_date). I want to display a list of authors and the latest book each of them has written. I made a method on the Author model: def get_latest_book(self): return self.books.all().latest('pub_date') That is working, but it's very inefficent when it comes to be rendered on a template: views.py: class AuthorListView(ListView): model = Author template_name = 'author_list.html' def get_queryset(self): return self.model.objects.filter(owner=self.request.user).order_by('name').prefetch_related('books') author_list.html: ... {% for author in author_list %} Name: {{author.name}} - Latest publication: {{author.get_latest_book}} {% endfor %} ... This is generating a large number of queries like: SELECT ••• FROM `app_book` WHERE `app_book`.`author_id` = 374 ORDER BY `app_book`.`pub_date` DESC LIMIT 1 36 similar queries. for each Author I have in the database! This results in huge loading times for the book list. How can I print on the template a list of Authors with their latest book in an efficient way? -

Can't add new fields to UserCreationForm in Django
I want to add some fields to my forms.py like below: from django.forms import ModelForm from django import forms from django.contrib.auth.models import User from django.contrib.auth.forms import UserCreationForm class CreatUserForm(UserCreationForm): first_name = forms.CharField() last_name = forms.CharField() email = forms.EmailField() class Meta: model = User fields = ['first_name', 'last_name', 'username', 'email', 'password1' ,'password2'] And also I created a register page: from django.shortcuts import render, redirect from django.http import HttpResponse, HttpRequest from django.forms import inlineformset_factory from urllib.parse import urlparse # from django.contrib.auth.forms import UserCreationForm from .models import * from .forms import CreatUserForm def registerPage(request): form = CreatUserForm() if request.method == 'POST': form = CreatUserForm(request.POST) if form.is_valid(): form.save() context = {'form': form} return render(request, 'main/page-register.html', context) So when I remove fields first_name last_name and email I can register as a user in page-register.html but when I use these fields I can't register new user. -
How to get the number of files from request.FILES.getlist('image')
and I'm trying to upload files in the app that I'm making. I have an input field (ImageField) that accepts multiple images to be uploaded once submitted. I do this via ajax, and so I want to return some sort of json object that has total count of images being tried to upload and number of images being actually uploaded. def post_update(request): save_status = {'update_save': False, 'image_count': 0, 'image_save': 0} if request.method == 'POST': update = UpdateForm(request.POST) if update.is_valid(): event = Event.objects.get(pk=request.POST['event_id']) update_form = update.save(False) update_form.update_by = request.user update_form.event = event update_form.save() save_status['update_save'] = True images = ImageForm(request.POST, request.FILES) files = request.FILES.getlist('image_path') save_status['image_count'] = request.FILES.count if images.is_valid(): for f in files: photo = Image( image_path=f, update_ref=update_form, image_title=images.cleaned_data.get('image_title')) photo.save() save_status['image_save'] += 1 I tried request.FILES.count and request.FILES.length in trying to get the count, but to no avail and keeps having an error. My question is basically how can i get the number of files in the request.FILES? -
Using a list of objects in Django Template
This is my first time to ask a question on here so apologies if it isn't structured very well. Basically what I have is a Model called Product, which at the minute has 7 products. I am looking to pull out 3 random products from this Model and store them in a list, which I then want to access from a template to show the 3 objects which are now in the list. My attempt at getting 3 random objects from the db: ## Finding 3 random products to show all_product_list = list(Product.objects.values_list('name', 'price', 'image')) checkout_products = list() counter = 3 num_products = len(all_product_list) while counter!= 0: random_prod = random.randint(0, num_products - 1) checkout_products.append(all_product_list[random_prod]) counter -= 1 Then in my template I am trying to access as follows: {% for checkout_prod in checkout_products %} <div class="col text-light"> {{ checkout_prod.price }} </div> {% endfor %} I am also rendering the list at the end of my function as follows : return render(request, 'cart.html', {'cart_items':cart_items, 'total':total, 'counter':counter, 'data_key': data_key, 'stripe_total':stripe_total, 'description':description, 'before_discount':before_discount, 'difference': difference, 'checkout_products': checkout_products,}) I am not getting any error, but there is nothing at all showing on the page, any help with this would be greatly appreciated.

Python, Django: list from .select_related("...")

I know there are ways to do it afterwards, but are there functions like for example... ...values_list("...", flat=True) ...to solve this directly in the query? Thanks for all your help! -

Django form.is_valid returns false when a FileField is set to required
So I'm trying to make a form in Django with a FileField. My forms.py looks like this: I want the FileField to be a required field. When forms.FileField(required = True) in forms.py, form.is_valid() returns false: When forms.FileField(required=False) in forms.py, form.is_valid() returns true: When I submit the form with forms.FileField(required = True) my print(form.errors) states: "This field is required" even though I do add a file. I tried different file formats to make sure the problem didn't just occur with the image I was using for testing. What am I missing? -
Dynamic Email Backend in Django
I would like to let my users decide their email backend on their own. That is why I have created the email relevant keys (host, port, username...) and now I try to work this backend into my Django project. My first attempt was to extend the default EmailBackend by my custom "UserBackend" which overrides the __init__ function like this: class UserBackend(EmailBackend): def __init__(self, user_id, host=None, port=None, username=None ...): user = User.objects.get(id=user_id) super().init(host=user.email_host, port=user.email_port ...) As this method is called (I tried to send_mail from the shell) it gets no user_id. How can I approach this differently or how would I extend my attempts to do this. I don't think it is good to essentially rewrite Djangos send_mail function (...) , as they are there and generic enough to fit my needs. -
Can't save tags in django

Can i have multiple views and serializers for single model in django rest framework
I am building an application in which an owner is posting a job post and multiple user will apply for that job application. I have provided an endpoint to user to apply for a certain job post and it went successful. Then, I tried to provide a separate endpoint to an owner in which I want to view the application and edit the status of the application. To implement this I used a separate serializer which allows only status field to be updated and making rest of the fields as read only. Additionally, I created the separate view as well for the owner to update the status of the application based on id filter. Lastly, creating a separate URL as well. So, the 2 URLs are: /api/job/application (for user) /api/job/application-status (for owner) But I ended up in a situation where I am getting the same URL for both of the job application endpoint and job application status endpoint because they are using same model. So, is it possible to have multiple views and serializers for a single model? If Yes, then how can I achieve this and what permissions should I use for owner. -

Django, MVC pitfalls for POSTs when rev proxy down, caching failed POSTs, none user Auth
Disclaimer Firstly, I understand SO is for code based answers, I did some research on where to ask this questions, and it seems like according to the community SO got 20 votes for asking: Questions about deployment and support of applications past release, in particular towards design for maintainability. Intro My question is I personally spent last 2 years working on a Django project for a factory, it uses the standard MVC pattern. The app uses the factory IP for authentication for terminals in the factory. It was my first web project and I have learnt a lot from it, and hence re-written many aspects of it. 3 Problems with Django MVC However I have now reached a point where I am wondering if it needs a re-write since I see no great solutions to the following problems with the MVC pattern: I wish to be able to POST data, and control what happens if it fails on the client side. With a normal POST, once one has submitted the form, one let's go of control. This means if the server is restarting, or receiving an update, and the reverse proxy (UWSGI) is not up yet, Nginx shows an error … -

Django. How do I add a field to a query result?
I have a Room model and I want to add the is_member boolean field to a queryset with rooms. How can do this? I was thinking of using .annotate (), but that doesn't work for my task. models.py from django.db import models class Room(models.Model): name = models.CharField(max_length=150) members = models.ManyToManyField(User, blank=True) views.py from rest_framework.views import APIView from rest_framework.response import Response from .serializers import RoomSerializer from .models import Room class RoomView(APIView): def get(self, request): rooms = Room.objects.all() # get all rooms user = request.user # get current user for room in rooms: members = room.members.all() # get members is_member = user in members # set boolean value room.is_member = is_member # set in room serializer = RoomSerializer(rooms, many=True) return Response(serializer.data) serializers.py from rest_framework import serializers from .models import Room class RoomSerializer(serializers.ModelSerializer) is_member = serializers.BooleanField(read_only=True) class Meta: model = Room fields = "__all__" I solved this issue this way, but is there any other options to do it?
