Python Django with Electron React boilerplate
I'm using Electron React boilerplate for a desktop application. Now I want to use python django apis for database and business logics I'm just preferring django because of my good knowledge in it. Now I need some suggestions whether it is a good approach or not. If yes so how can I make standalone file for this approach django+eletron-react. I searched this on internet but didn't find answer -

What is the proper way to pass a JS object as a django field value?
Given the following form: from django import forms class MyForm(forms.Form): my_field = forms.CharField() views.py from django.shortcuts import render from myapp.forms import MyForm def index(request): form = MyForm() if request.method == 'POST': form = MyForm(request.POST) return render(request, 'index.html', {'form': form}) index.html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <form method="post"> {% csrf_token %} {{ form }} <button type="submit">Submit</button> </form> </body> </html> I don't mean the field to be a character field, it's just for the sake of the example. What would be the proper and safe way to pass a JS object as the field value? This would be one possible way to do it. I'm not sure how safe or proper this is: document.querySelector('#id_my_field').value = JSON.stringify({a: 1, b: 2}) and then parse the resulting string: >>> json.loads(form.cleaned_data['my_field']) {'a': 1, 'b': 2} Yeah, I know I could just create a and b fields and make them numeric or whatever the dtype is but this is not an option in my case because these field values will be set dynamically and how many values are expected cannot be known in advance, so this is the convenient way to pass as many values as needed. -

How to get average by month in Django queryset?
I have been trying to get average values per month for the rainfall. There are dates, hours and values (hours don't matter here since average will be of all values per month). class TimeSeries(models.Model): station = models.ForeignKey(Station, on_delete=models.CASCADE) date = models.DateField() hour = models.IntegerField() value = models.FloatField() What i have tried is: delta = relativedelta(months=1) dateStart=TimeSeries.objects.values('date').order_by('date').values_list('date',flat=True).first() dateEnd=TimeSeries.objects.values('date').order_by('date').values_list('date',flat=True).last() for i in range(len(stationNumbers)): while dateStart <= dateEnd: timeSeries = TimeSeries.objects.filter(station__number=stationNumbers[i],date__range=[dateStart,dateStart+delta]).annotate(month=TruncMonth('date')).values('station__number','month').annotate(value=Avg('value')).order_by( 'station__number','month') I have tried making some changes into the query but it doesn't work in any way. Should i be using raw SQL here? and Can someone kindly help? i am new to Django. Thanks in advance. -

How to allow users to attach multiple images to a Django post using a ModelForm and formset?
I'm building a Django app that allows users to create posts and attach images to those posts. Each user can create multiple posts, and each post can have multiple images. I'm using a ModelForm to handle the creation of posts, but I'm having trouble figuring out how to handle the creation of the images associated with each post. Here's my current code: models.py class Post(models.Model): title = models.CharField(max_length=200) body = models.TextField() class Image(models.Model): post = models.ForeignKey(Post, on_delete=models.CASCADE) image = models.ImageField(upload_to='post_images/') forms.py class PostForm(forms.ModelForm): class Meta: model = Post fields = ['title', 'body'] views.py def create_post(request): if request.method == 'POST': form = PostForm(request.POST) if form.is_valid(): post = form.save(commit=False) post.author = request.user post.save() return redirect('post_detail', pk=post.pk) else: form = PostForm() return render(request, 'create_post.html', {'form': form}) What's the best way to modify my code to allow users to attach multiple images to their posts when they create them? How can I modify the PostForm to handle this, and how should I modify the create_post view to save the images along with the post? Any help is greatly appreciated! -
Candy translate to translate the data returned from controllers.py to javascript?

When using group by count in a subquery using python django, an error occurs

However, if I add a filter condition to the subquery, an error occurs. flower_order_count = FlowerOrder.objects.filter(funeral_hall_id=OuterRef('id'), order_status='complete').annotate(flower_order_count=Func('funeral_hall_id', function='Count')).values('flower_order_count') hall_list = FuneralHall.objects.annotate(flower_count=Subquery(flower_order_count)) The error is 'Expression contains mixed types. You must set output_field.' occurs, but output_field doesn't seem to matter. When using group by count in a subquery, I shouldn't add a condition to the filter. Is there a way to add it? I've tried adding output_field to the subquery, and I've tried meeting different conditions. All failed to work. -

integrating fusionauth and django-rest-framework
I am trying to integrate FusionAuth and Django-Rest-Framework (with a React frontend), and am getting very confused. I have some code that kind of works. It uses the "authorization code grant". The React frontend redirects to the FusionAuth login page which once submitted redirects back to the frontend with an authorization_code as a URL Parameter. The frontend passes that code to the Django backend which exchanges it for an access_token. That access_token is used to get some user information from FusionAuth including a unique id with which to create a local Django User (if one doesn't already exist). It then generates a local token and passes that to the frontend to use for authentication in future requests. Here is some pseudo-code: from fusionauth.fusionauth_client import FusionAuthClient client = FusionAuthClient(FA_API_KEY, FA_URL) def authenticate(request): authorization_code = request.data["code"] fa_token_response = client.exchange_o_auth_code_for_access_token() fa_user_response = client.retrieve_user(user_id=fa_token_response["userId"]) user, created = UserModel.objects.get_or_create( fa_id=fa_token_response["userId"], defaults={ "username": fa_user_response["username"], "email": fa_user_response["email"], }, ) token = generate_token(user) # THIS IS PROBABLY WRONG return Response( { "token": token, "user_id": user.id, } status=status.HTTP_200_OK, ) As you can see, I generate my own token (I happen to be using knox, but that's not important). But I want to just use the same access_token provided by … -

What is best practice for storage of AWS credentials within a django application?
I'm new to using AWS Services and Django together and I'm having trouble finding information around best practices for storing your aws creds for Django to access? I have a basic django application that's connected to an S3 bucket, so I need to be able to use boto to invoke the connection to the bucket. But I'm not sure how to go about storing the aws credentials I would need to pipe into my boto functions to use any of the services. I have read in a few places of people putting their aws credentials into the settings.py file within their django project, but this doesn't really feel secure to me. I also looked into AWS Secrets Manager, but it looks to me as though it's more suited for keys related to other services. Could anyone perhaps explain what my other options are, or why storing them in settings.py is perhaps a safe option? Really not certain on the best way to go about this one. -

Django: socket doesn't seem to connect without returning any errors
my name is Liran and I am currently working on my computer science final project. my project is a web based ide with the main selling point of a room feature in which a couple of people can work on the same code together. for the backend I am using python - Django and for the frontend I am using JS and bootstrap for the design. At first I wanted to just create a basic html page in which I can write some text into a text-area and for every new input to the text area the server would get notified and update everyone via the socket and when someone pressed the submit button the code will run on the server and the outpot is returned real time (I know the security risks and how not smart it is to do that I just need a fast way to do it for my project). After getting a fully skeleton of the project (you can see the working skeleton of the project in the dev branch in the GitHub page) I started making a way to create "rooms" in which people can work together in a costume socket. For this I … -

How to transfer data from a JavaScript variable to a python file in a Django project?
I'm making a recipe generator website where each ingredient is an image inside a div. When that div is clicked, it toggles to another colour. When submit is clicked, I want the ids of all the selected divs to be consolidated into one array. I'm able to achieve this using JavaScript, using the following code. $(document).ready(function () { var selectedDivs = []; $(".square").click(function () { $(this).toggleClass("selected"); var divId = $(this).attr("id"); var index = selectedDivs.indexOf(divId); if (index === -1) { selectedDivs.push(divId); } else { selectedDivs.splice(index, 1); } }); $("#submit").click(function () { $("#result").text("Selected Divs: " + JSON.stringify(selectedDivs)); }); }); How do I now send this data to the views.py file in my Django project, where it can become a list? Or is there a way to achieve this functionality directly in the python file itself? I tried using AJAX but I'm not sure how to link the pages properly. -
can we use image url to detect video content in OpenCv
I am a beginner in OpenCV and I want to use it to detect video content that contains nudity. I tried using image_url to prompt OpenCV to display an error message when a user attempts to post a video file containing that image, but the method I used below did not work. The video was uploaded to my database. Could you please point out where I went wrong? Also, please note that the picture stored in the nude_url variable does not contain any nudity as Stack Overflow does not support such pictures. def create_video(request): if request.method == 'POST': video = request.FILES.get('video') cap = cv2.VideoCapture(str(video)) nude_url = 'https://ichef.bbci.co.uk/news/976/cpsprodpb/17638/production/_124800859_gettyimages-817514614.jpg while(cap.isOpened()): ret, frame = cap.read() if cap == nude_url: raise ValidationError('This video contains nudes, but nudes are not allowed') if video: video_type = video.content_type.split('/')[0] if video_type != 'video': raise ValidationError('File is not a video') video_ext = video.name.split('.')[-1] if video_ext not in ['mp4', 'avi', 'mov']: raise ValidationError('Unsupported video format') video_clip = VideoFileClip(video.temporary_file_path()) duration = video_clip.duration video_clip.close() if duration > 600: # 10 minute in seconds raise ValidationError('the video cannot be longer than 10 minute') new_video = Video.objects.create( user=request.user, video=video, ) new_video.save() return redirect('Video') else: raise ValidationError('No video file uploaded') return render(request, 'video/create_video.html')
