How to print multiple values from two lists in django template
I am trying to figure out a way to print values from two different context variables in a single loop. I have tried the zip() method but it does not seem to work and does not print variables on the template. This is how I tried index.html <tbody> {% for item1, item2 in mylist %} <tr> <td><a href="/{{ url.short_url }}">/{{ item1.short_url }}</a></td> <td>{{ item1.original_url }}</td> <td>{{ item1.created_at }}</td> <td>{{ item1.clicks|intcomma }}</td> <td>{{ item2.browser }}</td> <td>{{ item2.platform }}</td> <td><a href="#"> <svg class="octicon octicon-graph" viewBox="0 0 16 16" version="1.1" width="16" height="16" aria-hidden="true"> <path fill-rule="evenodd" d="M16 14v1H0V0h1v14h15zM5 13H3V8h2v5zm4 0H7V3h2v10zm4 0h-2V6h2v7z"> </path> </svg> </a></td> </tr> {% endfor %} </tbody> views.py def index(request): urls = Url.objects.order_by('-created_at') clicks = Click.objects.order_by('-created_at') # context = {'urls': urls, 'clicks': clicks} mylist = zip(urls, clicks) context = { 'mylist': mylist, } return render(request, 'heyurl/index.html', context) But on running the local server I don't see anything on the table view. What am I doing wrong here? Are there any alternatives ? Here's my current version of code. models.py from django.db import models class Url(models.Model): short_url = models.CharField(max_length=255) original_url = models.CharField(max_length=255) clicks = models.IntegerField(default=0) created_at = models.DateTimeField('date created', auto_now_add=True) updated_at = models.DateTimeField('date updated', auto_now=True) class Click(models.Model): url = models.ForeignKey(Url, on_delete=models.CASCADE, related_name='related_clicks') browser … -

Django Queryset not working after tranformation to Abstract class child
For more than a year, I construct many of my query using a Django Model where I have simple relation between none abstract model objects and everything was working perfectly : class Taxon(models.Model): parent = models.ForeignKey("self", on_delete=models.CASCADE, null=True, blank=True, related_name='children') rank = models.CharField(max_length=200, unique=False, default="NA") name = models.CharField(max_length=200, unique=False, default="NA") class Sequence(models.Model): taxon = models.ForeignKey(Taxon, null=True, blank=True, on_delete=models.CASCADE) amplicon = models.CharField(max_length=1000, unique=False) sequence = models.CharField(max_length=1000, unique=False) score = models.FloatField() Exemple of queryset using my Model : taxon.sequence_set.filter(stuff_filtering) But recently I had to apply some modifications on my database and my Sequence objects are now derivated from an Abstract class called Observation, becoming this class Observation(models.Model): taxon = models.ForeignKey(Taxon, null=True, blank=True, on_delete=models.CASCADE) class Meta: abstract = True class Sequence(Observation): amplicon = models.CharField(max_length=1000, unique=False) sequence = models.CharField(max_length=1000, unique=False) score = models.FloatField() def __str__(self): return str((self.amplicon, self.sequence, self.score, self.taxon)) I didn't changed anything in my queryset because django documentation about abstract class (https://docs.djangoproject.com/en/3.2/topics/db/models/) say you can still use your chlid_set in a query. However i'm facing this error and I couldn't understand why. AttributeError: 'QuerySet' object has no attribute 'sequence_set' Knowing that in case of Abstract base classes, a table should be created in db for each child with parent attribute... So i … -

User passes test in django to check subscription

Value: "" must be an instance of <class 'dict'> in django, djongo
I am using Django and connecting with a mongodb database using djongo. My database requirements are such that I need to use an embedded field in one of the collections. On adding any entry on Django Admin I am getting a preview error - I have 2 models, City containing 3 fields, and the Address containing 2 fields a city object and a pincode. Hence the city is an embedded field in model Address. On adding this entry through django-admin an error message pops up, and the entry doesn't get saved in the database. Please correct the error below -> Value: gwalior-MP-India must be an instance of <class 'dict'> An entry in address table looks like - { "city": { "city":"gwalior", "state":"MP", "country":"India" }, "pincode":"9999" } P.S. - I was not able to attach the screenshot of django-admin panel, as I was getting an error while posting this question -> Failed to upload image; an error occurred on the server.

How to extracting long views code block in a smaller method?
I have a Django application. And I have a long method where a user can upload a file and the content of the file will be shown in textarea. Because of the S.O.L.I.D principle. The code that is responsible for extracting the data from the file has to be in a seperate method. So this is the views.py: class ReadingFile(View): def get(self, request): form = ProfileForm() return render(request, "main/create_profile.html", { "form": form }) def extractingtextfromimage(): pass def post(self, request): submitted_form = ProfileForm(request.POST, request.FILES) content = '' if submitted_form.is_valid(): uploadfile = UploadFile(image=request.FILES["upload_file"]) name_of_file = str(request.FILES['upload_file']) uploadfile.save() print('path of the file is:::', uploadfile.image.name) with open(os.path.join(settings.MEDIA_ROOT, f"{uploadfile.image}"), 'r') as f: print("Now its type is ", type(name_of_file)) print(uploadfile.image.path) # reading PDF file if name_of_file.endswith('.pdf'): pdfFile = wi(filename= uploadfile.image.path , resolution=300) text_factuur_verdi = [] image = pdfFile.convert('jpeg') imageBlobs = [] for img in image.sequence: imgPage = wi(image=img) imageBlobs.append(imgPage.make_blob('jpeg')) for imgBlob in imageBlobs: image = Image.open(io.BytesIO(imgBlob)) text = pytesseract.image_to_string(image, lang='eng') text_factuur_verdi.append(text) content = text_factuur_verdi print(text_factuur_verdi) # ENDING Reading pdf file else: content = f.read() print(content) return render(request, "main/create_profile.html", { 'form': ProfileForm(), "content": content }) return render(request, "main/create_profile.html", { "form": submitted_form, }) And it is about the comment: reading PDF file till: # ENDING Reading pdf file … -

context must be a dict rather than type
I've been working on a project for a while, and I have a resource called Item. The item detail view can only be viewed, if the item is from the same company as the user. If not, it should be a 404. This is the code that I have: def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) # To only show items in your company if (context['item'].company != getCompany(self.request.user)): return HttpResponseNotFound return context getCompany is a function I wrote to check the users company. The company is in a custom Profile model. This function works, I already used it multiple times for other things Now i expected to have a 404 when going to a item from another company, but instead this error appears: Internal Server Error: /fr/items/5/ Traceback (most recent call last): File "/Users/username/Documents/Work/Inventory/inventory-env/lib/python3.9/site-packages/django/core/handlers/exception.py", line 55, in inner response = get_response(request) File "/Users/username/Documents/Work/Inventory/inventory-env/lib/python3.9/site-packages/django/core/handlers/base.py", line 220, in _get_response response = response.render() File "/Users/username/Documents/Work/Inventory/inventory-env/lib/python3.9/site-packages/django/template/response.py", line 114, in render self.content = self.rendered_content File "/Users/username/Documents/Work/Inventory/inventory-env/lib/python3.9/site-packages/django/template/response.py", line 92, in rendered_content return template.render(context, self._request) File "/Users/username/Documents/Work/Inventory/inventory-env/lib/python3.9/site-packages/django/template/backends/django.py", line 58, in render context = make_context( File "/Users/username/Documents/Work/Inventory/inventory-env/lib/python3.9/site-packages/django/template/context.py", line 278, in make_context raise TypeError( TypeError: context must be a dict rather than type.

I'm building a simple Lead Generator using Django Rest Framework. I'm trying to show a list of "assigned facilities" inside a lead using django's many to many fields.

Using HTMX/Javascript in Django Template : not defined
I decided to try HTMX with Django and implementing a Django form in a modal box. I found this tutorial and was following it. I got to the part where it uses an HTMX function htmx:afterSwap to open the modal but when I put that in a script tag in the template, I run into an error. It is Step 4 where the error occurs.

how do I convert PCM 16bit signed LE 16000kHz to WAV in python given only the bytes?
I pulled an object from amazon s3 buckets like so: s3_response_object = S3.get_object(Bucket=bucket_name, Key=key_name) object_content = s3_response_object['Body'].read() # object content --> b'\x06\x10...' Inside the bucket you have a PCM 16bit signed LE 16000kHz audio file. If you write that file to a .wav file like so: with open("audio.wav", "wb") as f: f.write() The wav file cannot be played by quicktime VLC or any audio player. How can I convert these bytes into a wav file. The end goal is to pass these bytes into a view with django, and I have already verified that my django view works properly using a drop in replacement stream of bytes to use for the view, and the audio plays back no problem. I think the bytes that I get from AWS need some type of conversion to be valid for passing into my view. Any help would be much appreciated.

Should I use Django Function based views or Class based views for better functionality?
I am just learning Django, and I am attempting a project to create a notes app. During the process of the project, a friend of mine advised me to use function-based views, but I later discovered that class-based views can be customized too. Given that both can work fine for my little project, is it best practice to use function-based views from scratch or to override class-based views methods? Thank you. -

How to call bussines logic from seperate class in view in Django?
I am using django framework. And I have some functionality for uploading files. And I have a textarea where the extracted content of the uploaded file will be shown. So for example if you upload a pdf file within a image that contains text. In the textarea the text will be shown. But the logic for extracting the text from the image of course doesn't belong too the method in the view. So I made a seperate class for it, with name: extractingTextFromFile.py that looks like this: import io from tracemalloc import start from PIL import Image import pytesseract from wand.image import Image as wi import re class ExtractingTextFromFile: def extractingtextfromimage(): text_factuur_verdi = [] #image = pdfFile.convert('jpeg') imageBlobs = [] for img in image.sequence: imgPage = wi(image=img) imageBlobs.append(imgPage.make_blob('jpeg')) for imgBlob in imageBlobs: image = Image.open(io.BytesIO(imgBlob)) text = pytesseract.image_to_string(image, lang='eng') text_factuur_verdi.append(text) and I have the views.py: from django.shortcuts import render from django.views import View from django.http import HttpResponseRedirect from .forms import ProfileForm from .models import UploadFile import extractingTextFromFile as textFromFile from wand.image import Image as wi from PIL import Image import pytesseract from django.conf import settings import io import os class ReadingFile(View): def get(self, request): form = ProfileForm() return render(request, "main/create_profile.html", …
