Django-import-export package post_save signal called twice
I am using the django-import-export package to import data from a model from the admin site. This model has a function for sending email that is executed with the post_save signal. The problem is that when the preview is generated (import confirmation) the function associated with the post_save is executed and then when I confirm the import, it is executed again, that is, the mail is sent twice. How to solve this problem? The following is the function with the @receiver decorator that uses the post_save signal @receiver(models.signals.post_save, sender=MiModel) def send_email(sender, instance, **kwargs): ..... server.sendmail(....) I am using Python==3.6.5, Django==3.0.5, django-import-export==2.5.0 -
Apache Django Internal Server Error (Ubuntu 18.04)

Django objects.get(): The QuerySet value for an exact lookup must be limited to one result using slicing
I'm trying to check if a user exists in the database based on email address, so I get the email and if that email exists, I want to return the username of that user alongside with some other data. I'm using objects.get() method to do so but I keep getting this error. Did some search on it, a couple of solutions were suggesting to do a filter and return the .first() object or instead of email=email, suggested to put email=email[0], but both of these approaches ended up giving me an empty array in response. Here's my Views.py: class CheckEmailView(APIView): permission_classes = [AllowAny] def post(self, request, *args, **kwargs): serializer = CheckEmailSerializer(data=request.data) serializer.is_valid(raise_exception=True) email = Account.objects.filter(email=serializer.data['email']) if email.exists(): username = Account.objects.get(email=email) return Response({'is_member': True, 'username': username}) else: return Response({'is_member': False}) -
Django admin keeps loading the wrong template

UNIQUE constraint failed: auth_user.username when trying to save the form
Whenever I try to register an account this error jumps out in the form.save() on the views.py code. I've tried some things but didn't work out.

Is there a way to avoid CORS error while in production in NuxtJS?
I have been using NuxtJS locally alongside Django Rest Framework and there have been no issue. However, after deployment on Netlify I started getting CORS error - although, I have axios proxy set. I had to rerun npm run generate and run the generated file locally for which I get the same error. I later found out that proxy doesn't work with statically generated NuxtJS app. I have searched Google tirelessly but I can't seem to get a direct solution. I have to deploy this app on Netlify without having access to Nginx or Apache server. Please can anyone suggest a simple solution to avoid CORS error 405. The repository containing the code is located here -

How do I iterate dictionary with lists as values in Django template?
I have a dictionary with lists as values (truncated to give you an example): imageFiles {'R01': ['02secparking27.jpg', '10-2017-ff-detail-1200x627.jpg', '1200x820.jpg', '12539233_web1_180704-VMS-parking-lot.jpg', '16.12.01-519196006.jpg',], 'R02': ['asdasd.jpg','12131asad.jpg','asdasdasd.jpg']} In the template, I am trying to access the image names by iterating but I am getting no values. {% for keys,values in imageFiles %} {% for x in values %} <p> {{X}} </p> {% endfor %} {% endfor %} getting error "Need 2 values to unpack in for loop; got 9." I also tried imageFiles.items as suggested in other posts and it doesn't seem to work. What am I doing wrong? Wracking my brain here. -
How to correctly write the location of the template file in settings (Django)

AWS Cognito in react js with django rest framework?
I want to integrate third party authentication with AWS Cognito in my webapp. I have a React JS app with a django backend. I found this tutorial but I dont really get how this will work with an existing frontend application rather than how to implement it. if a user logs into the frontend and is authenticated via cognito (other question: is a backend in Amplify necessary?), can the token be passed to the django API - does cognito then need to be called again in django? this step is not yet completely clear to me. Any help is appreciated. Are there no examples for react + DRF? -
Loading aws s3 lamda generated files in Django
Whats working I have a Django website application form that takes an image from a user and uses django-storages to save the uploaded images to a AWS S3 bucket: <bucket>/private/images/file_name.jpg On upload, I have an AWS SNS triggered that executes a Lambda function to filter the users image and store it in the same S3 bucket <bucket>/private/filtered_images/file_name.jpg; the SNS is only triggered on the images folder in order to avoid recursive Lambda evaluations. Whats the problem I want a good way to reference the Lambda generated filtered images in my Django application. Currently, my django image model is: class Image(models.Model): title = models.CharField(max_length=200) image_owner = models.ForeignKey(image_owner, on_delete=models.CASCADE, null=True) # image owner has multiple images source_image = models.ImageField(storage=PrivateMediaStorage(), upload_to="images/", null=True, blank=True) def get_absolute_url(self): return reverse('image-detail', args=[str(self.id)]) def get_update_url(self): return reverse('image-update', args=[str(self.id)]) def get_delete_url(self): return reverse('image-delete', args=[str(self.id)]) where class PrivateMediaStorage(S3Boto3Storage): location = settings.AWS_PRIVATE_MEDIA_LOCATION default_acl = 'private' file_overwrite = False custom_domain = False It would be ideal if I could somehow add a filtered_image field to the Image model upon the creation of Image, even though the processing for the filtered_image would only start when source_image is uploaded (due to the nature of the s3 -> lambda trigger I have set).

Only able to add two child objects in Django using a ModelForm and inline_formsets
I'm making a recipe application in Django. Each user has their own OneToOne RecipeBook object, which in turn can hold as many recipes as needed, as each Recipe has a ForeignKey relationship to the RecipeBook object. There are also Ingredient and Direction objects that each have a FK relationship to the Recipe object. I am trying to make a form that allows the user to create a Recipe, and then dynamically add/remove Ingredient/Direction objects as needed. I'm using Class Based Views, ModelForms, and inlineformsets_factory to accomplish this, as well as using the django-dynamic-formset jQuery plugin, and I've been following this guide. My issue is that I am only able to create two child Ingredient/Direction objects for each recipe. I want to make it so users can create as many Ingredient/Direction objects as they like. Previously I was only able to add one instance of each child object, but through some changes I don't recall, I am now able to add two. I previously thought that I would need to iterate over each object in my view to allow multiple objects, but since I can now create two I'm not sure if that is the case. So my question is, what … -
In django, what is the optimal way to access data in a OnetoMany relationship to output to template?
I'm working in django and my objective is to output to a template a table consisting of all my customers and a corresponding amount equal to the total amount they have spent. I have the classes/models Customers and Transactions with a OneToMany relationship. Every time a customer makes a purchase, the transaction is recorded as is the amount they spent (tx_amount). I have the following set a code that works but I believe is not optimal since its running in O(x * y) time, i.e., running a full loop over Transactions for every customer. Q1: What is the optimal way for accomplishing this task? When I originally tried to get my template to work, instead of using local_customer, I was using setattr(customer[x],"value",tx_amount) which worked in the django shell but did not work in the template. My workaround was to create a local class which I would use to population my context variable. Q2: When combining data models to output in a template, is it necessary to use some sort of local class like my local_customer implementation below or is there a better way? Pseudo-code below: models.py: class Customers(models.Model): name = models.CharField(max_length=70) def __str__(self): return self.name class Transactions(models.Model): customers = models.ForeignKey(Customers, … -

I can't seem to get a Docker-Nginx-Django app to refresh the static files
I currently have a Django website that runs on a server using Nginx an Docker. Every time I update my main css file and deploy it, nothing changes, despite hard refreshing the site. When new static files are added, they end up working, but modified files don't seem to change. This led me to believing that nginx or Docker was caching the file. I've tried the following: Clearing the cache in the nginx container, setting the lines expires -1 and sendfile off, rebuilding the containers, with no luck. The last time I had this problem, I believe I had to delete the volume for it to refresh, which I don't think is a good solution. Can someone explain what I am doing wrong?

Django Rest Framework: changing output format of annotated field in queryset
Hello StackOverflow community, I am currently struggling with specifying an output format in my views.py. I have a column "date" which is using following format: 2021-01-14. In my response, I would like to change the date format so that it only shows the year 2021. I already tried it with Cast but it seems like this is not the right approach. For this view, I do not use a Serializer, hence adding it there would not be an option. views.py class FilterParams(generics.ListAPIView): model = Variants queryset = Variants.objects.all() def get(self, request, *args, **kwargs): queryset = self.get_queryset() ModelsByYears = queryset.values('model').distinct().annotate(min_year=Min('date')).annotate(max_year=Max('date')).order_by('model') return Response(data= {'ModelsByYears':ModelsByYears}) What I tried: class FilterParams(generics.ListAPIView): model = Variants queryset = Variants.objects.all() def get(self, request, *args, **kwargs): queryset = self.get_queryset() ModelsByYears = queryset.values('model').distinct().annotate(min_year=Min(Cast('date', DateTimeField(format="%Y")))).annotate(max_year=Max('date')).order_by('model') return Response(data= {'ModelsByYears':ModelsByYears}) Error message TypeError: __init__() got an unexpected keyword argument 'format' -
