Convert the binary api Response into a pdf file in python
I have to call a api which gives me the response in binary, now I have to convert this to a readable pdf and send as attachment in mail.

How can I style a django form with css?
I tried looking for the answer earlier but couldn't seem to figure out a few things. I'm creating my form in a form.py file so its a python file. Here is my forms.py file : class UploadForm(ModelForm): name = forms.TextInput(attrs={'class': 'myfieldclass'}) details = forms.TextInput() littype = forms.TextInput() image = forms.ImageField() class Meta: model = info fields = ["name", "details", "littype", "image"] Here is my views.py function for it if it helps find the solution : def uploadform(request): if request.method == 'POST': form = UploadForm(request.POST, request.FILES) print(request.FILES) if form.is_valid(): form.save() redirect(home) return render(request, 'uploadform.html', {'form': UploadForm}) To style it I thought I could do something like this which I found in another question : class MyForm(forms.Form): myfield = forms.CharField(widget=forms.TextInput(attrs={'class': 'myfieldclass'})) Except I have no idea how to link a css page to that python file. This is what I tried writing but i think it doesnt work because its meant for html but its in a python file : <link type="text/css" rel="stylesheet" href="templates/form.css"> And so I'm just not sure how to style my form. Thanks for any answers! -
Django-Summernote not displaying as intended when in a modal/hidden div

How do you post data in django with attribute depth=1 in the serializer?
I have a django model called “Enrolment” that depends on two other models through foreign key. “Course” model and “Enrolment” model. The “Course” model is like so: class Course(models.Model): name = models.CharField(max_length=100, blank=True) description = models.TextField(blank=True) prerequisite = models.TextField(blank=True) fee = models.FloatField(default=0.0) def __str__(self): return self.name And the Enrolment model is like so: class CourseEnrolment(models.Model): course_name = models.ForeignKey( Course, on_delete=DO_NOTHING) schedule = models.CharField(max_length=50, blank=True) student = models.ForeignKey( UserAccount, on_delete=DO_NOTHING) enrolment_date = models.DateTimeField(default=datetime.now()) def __str__(self): return self.course_name.name For me to gain access to the information about the enrolled course, I have to do like so in the CourseEnrolmentSerializer: class CourseEnrolmentSerializer(serializers.ModelSerializer): class Meta: model = CourseEnrolment depth = 1 fields = '__all__' With “depth = 1” being the secret to accessing information about the course. Now when I fetch enrolment, I get a response like below, which is exactly what I want like so. { "id": 5 "schedule": "June 23, 2022", "course_name": { "id": 4, "name": "fundamentals-of-programming", "description": "some description .", "prerequisite": "some prerequisite", "fee": 1000, }, "student": { "id": 1, "email": "martinsakinbo@yahoo.com", "first_name": "John", "last_name": "Doe", "phone": "1111111", } }, Now, the problem I have is that with “depth=1” in the serializer, I’m not able to create an enrolment when I … -

Counting all items within django-treebeard Materialised Path nodes
I'm using django-treebeard to create a tree of Categories, each of which contains some Books: from django.db import models from treebeard.mp_tree import MP_Node class Book(models.Model): title = models.CharField(max_length=255, blank=False, null=False) categories = models.ManyToManyField("Category", related_name="books", blank=True) class Category(MP_Node): title = models.CharField(max_length=255, blank=False, null=False) book_count = models.IntegerField(default=0, blank=False, help_text="Number of Books in this Category") total_book_count = models.IntegerField(default=0, blank=False, help_text="Number of Books in this Category and its descendants") I want to display the number of Books in each Category, stored in Category.book_count, so I have a post_save signal like this: from django.dispatch import receiver @receiver(post_save, sender=Book) def book_post_save(sender, **kwargs): for category in kwargs["instance"].categories.all(): category.book_count = category.websites.count() category.save() (The reality is a bit more complicated, but this is the gist.) This works fine, and I can also do similar on an m2m_changed signal for if a Book's Categories have changed. BUT, I also want to calculate total_book_count - the total number of Books in a Category and in all of its descendant Categories. I can do this with a method like this on Category: def set_total_book_count(self): # All the Books in this Category's descendants: descendant_books = Book.objects.filter(categories__in=self.get_descendants()) # Combine with the Books in this Category but avoid counting duplicates: books = (descendant_books | self.books).distinct() … -
Connecting local data to Docker Django project
This is a question to understand what should be the best practice to follow in order to connect the dots on the argument. Currently I am developing a Dockerized Django website. In this website, one of the apps will be named 'dashboards', where I wish to publish data which is currently stored locally in .csv (updated every day through scheduled tasks). Now, I am trying to understand what should be the next steps to follow in order to connect these data to the Dockerized Django website. My first guess would be to schedule locally .sql scripts to 'append' the new data into the db that I can create locally. Then, connect the db to the Dockerized Django website through volumes belonging the postgreSQL service. Just a guess that I need to test. But, is there a way to skip everything locally and just do the work inside my Docker container? You can find the Github repository here.

How to mock Django command which inserts data into django model

Use prefetched data on django form to set field queryset
I am not sure how to set form fields using prefetched data. I am fetching a questionnaire section and then pre fetching the questions in the section.

Django/Djoser Login Through React
I'm quite new to web development in general. So my django/react skills are quite poor. I'm not entirely sure what code I would need to post here to be able to effectively explain my issue. Essentially I'm trying to create a saas product which displays different data for each user. I can't seem to be able to get django to recognise that a user has logged in. At the moment I'm able to log in a user through my react app by sending a post request through djoser. This logs in and keeps the user logged in but it doesn't seem like django recognises this log in. I've tried adding in the react build into a django application but I'm getting the same result when doing this. I feel like I need to add something into the django app that contains my react build but I have no idea what or where to look. I'm not sure which pieces of code to add here as there are so many and I'm not entirely sure where the issue lies. So if someone requests to see anything I will upload whatever will be useful.

How can I implement publisher subscriber model using rabbitMQ and celery in Django?
As I know there are 2 main models in message queue, Publish/Subscribe and Producer/Consumer. Producer/Consumer is easy to implement and hte main concept would be that some app will be pushing into my message queue and one out of multiple celery workers will pick the message and process the same. This can be done by creating workers with the help of celery. However what I don't understand is how exactly would a publisher subscriber work with RabbitMQ and celery in Django. As I understand message produced by publisher is consumed by all subscribers that have subscribed to specific queue . Publishers produce messages while subscriber consumes message. So my question is how exactly can I use celery workers to subscribe to queues, how would this work exactly with Django. Any theory, blog, docs or videos that explains the same with Django, celery and any message queue would help -
Django Rest Framework reset password
I am following a tutorial on YouTube and wonder why we need the PasswordTokenCheckAPI in views.py because we then verify the uidb64 and token again in the SetNewPasswordAPIView anyway (in the serialiser.is_valid(), we also check if the token and uidb64 are valid). Can we just give the url to the reset password page directly in the email and verify things later when the user submits the password reset request? class RequestPasswordResetEmail(generics.GenericAPIView): serializer_class = ResetPasswordEmailRequestSerializer def post(self, request): serializer = self.serializer_class(data=request.data) email = request.data.get('email', '') if User.objects.filter(email=email).exists(): user = User.objects.get(email=email) uidb64 = urlsafe_base64_encode(smart_bytes(user.id)) token = PasswordResetTokenGenerator().make_token(user) current_site = get_current_site( request=request).domain relativeLink = reverse( 'password-reset-confirm', kwargs={'uidb64': uidb64, 'token': token}) redirect_url = request.data.get('redirect_url', '') absurl = 'http://'+current_site + relativeLink email_body = 'Hello, \n Use link below to reset your password \n' + \ absurl+"?redirect_url="+redirect_url data = {'email_body': email_body, 'to_email': user.email, 'email_subject': 'Reset your passsword'} Util.send_email(data) return Response({'success': 'We have sent you a link to reset your password'}, status=status.HTTP_200_OK) class PasswordTokenCheckAPI(generics.GenericAPIView): serializer_class = SetNewPasswordSerializer def get(self, request, uidb64, token): redirect_url = request.GET.get('redirect_url') try: id = smart_str(urlsafe_base64_decode(uidb64)) user = User.objects.get(id=id) if not PasswordResetTokenGenerator().check_token(user, token): if len(redirect_url) > 3: return CustomRedirect(redirect_url+'?token_valid=False') else: return CustomRedirect(os.environ.get('FRONTEND_URL', '')+'?token_valid=False') if redirect_url and len(redirect_url) > 3: return CustomRedirect(redirect_url+'?token_valid=True&message=Credentials Valid&uidb64='+uidb64+'&token='+token) else: return …
