Passing data from form in html to views.py not working
I passed the id value from html form to views .py. I want to check if the value matches with the one in database. But for some reason it's not working. list.html <form method= 'POST' action = "{% url 'jobs:pinned'%}"> {% csrf_token%} <input type ="text" name = "number"> <input type="submit" value="Submit"> </form> views.py def pinned(request,category_slug=None): users = User.objects.exclude(id=request.user.id) jobs_list1 = Jobs.objects.all() if request.method =="POST": vari = request.GET.get('number') for evert in jobs_list1: if evert.Job_Id == vari: evert.flag = True evert.save(update_fields=["flag"]) context = { 'job_list1':jobs_list1, 'users':users } return render(request, 'jobs/product/list.html',context) Here, if i put a static value as 511, i.e if evert.Job_Id ==511, it works. But if i change it to request.GET.get('number'), it's not working. How do i send value from form input value to views.py. Thanks. -

How to extract and save files from PDF in a Django Model
I'm working on a project right now that needs to extract PDFs attached to a Model. The PDFs are then related to the Project as the below models.py: class Project(models.Model): name = models.CharField(max_length=100) files = models.FileField('PDF Dataset', help_text='Upload a zip here', null=True) class Pdf(models.Model): name = models.CharField(max_length=100) file = models.FileField(null=True) project = models.ForeignKey(Project, on_delete=models.CASCADE) I then have a task I can trigger via Celery to extract the PDF and save each as its own record. My sample tasks.py below: from django.core.files.base import ContentFile from celery import shared_task from zipfile import ZipFile import re def extract_pdfs_from_zip(self, project_id: int): project = Project.objects.get(pk=project_id) ... # Start unzipping from here. # NOTE: This script precludes that there's no MACOSX shenanigans in the zip file. pdf_file_pattern = re.compile(r'.*\.pdf') pdf_name_pattern = re.compile(r'.*\/(.*\.pdf)') with ZipFile(project.files) as zipfile: for name in zipfile.namelist(): # S2: Check if file is .pdf if pdf_file_pattern.match(name): pdf_name = pdf_name_pattern.match(name).group(1) print('Accessing {}...'.format(pdf_name)) # S3: Save file as a new Pdf entry new_pdf = Pdf.objects.create(name=pdf_name, project=project) new_pdf.file.save(ContentFile(zipfile.read(name)), pdf_name, save=True) # Problem here print('New document saved: {}'.format(new_pdf)) else: print('Not a PDF: {}'.format(name)) return 'Run complete, all PDFs uploaded.'

Problem with Data Type in my Python/Django Code
I'm running into a noob issue with my code. It's a simple multiplier function working like as: 1/ A Model 1.a/ with 2 fields : name as CharField and price as Decimalfield 1.b/ with a method Multiplier that is basically newprice = self.price * arg 2/ A form to capture an input (the value to multiply self.price with) 3/ A view to pass the template with the form and the context I keep running into can't multiply sequence by non-int of type 'NoneType' or TypeError: unsupported operand type(s) errors.

How to Fix "Models aren't loaded yet" in Django

Django Query Filter syntax issue
I'm using Django 1.10.5 with python 3.6. I have the following model classes: class PublishedDetails(FillableModelWithLanguageVersion): user = models.ForeignKey(settings.AUTH_USER_MODEL) .... class PublishedRecordedActivity(models.Model): published_details = models.ForeignKey(PublishedDetails, null=False, blank=False, on_delete=models.CASCADE) timestamp_added = models.DateTimeField(auto_now_add=True) activity_type = models.IntegerField(null=False, blank=False, default=1) With a lot of assistance, I have a query that will return all the details for the activity type of 1: aggregated_type_1 = PublishedRecordedActivity.objects.filter( activity_type=1).annotate(month=TruncMonth('timestamp_added')).values( 'month').annotate(sum_by_month=Count('month')).order_by('-timestamp_added') However, I now want to only return the query for specific published details. For example where published_details=73, where the 73 is the id value in the model/table PublisheDetails. So I extended the query, but I'm receiving the error: 'publisheddetails__id' is not defined. I have imported the models to the view. Here is the offending query: aggregated_type_1 = PublishedRecordedActivity.objects.filter( activity_type=1, published_details=publisheddetails__id).annotate(month=TruncMonth('timestamp_added')).values( 'month').annotate(sum_by_month=Count('month')).order_by('-timestamp_added') I have tried back tracking and I have referenced the django docs, but the solution is escaping me. -

Django channels 1.x authenticate user
I run a django server and am trying to create a channel for chatting. The client is a react-native application, with javascript backend. When the user connects to the server via websocket (ws_connect), I want to be able to perform an authentication check, to see if the user is already in the database and get who this user is. I use default django auth accounts (django.contrib.auth.models). For authenticating the http requests I use django.contrib.auth.decorators.login_required and from the client I send an Authorization Header with the JWT token. How should I do the same for websocket requests? The recommended chat consumer uses channels.auth.channel_session_user_from_http. Is this the correct way for what I want? And how can I send the user's credentials (or token) from the client so that the server can check them? I saw a relevant SO question and the relevant documentation, but could not solve my problem. Any help would be appreciated. django version: 1.11.20 django-channels version: 1.1.8 -

How to parse output of .serialize('json', data) from Django in HTML
I'm trying to loop through a serialized JSON object and display it as a list, but instead of listing the attributes I want, the loop runs over each individual character in the JSON string.

What is the rightway of importing and inheriting classes?
I am relatively new to programming. So far I have seen two ways that classes are imported and inherited in python. The first one which is also what I have been doing while learning Flask is: from package.module import SuperClass class SubClass(SuperClass): The other one which I am seeing quite often in most Django code is: from package import module class SubClass(module.SuperClass): Which one is the right way of doing things? Is there a significant advantage of using one over the other? -

How to use multiple user models in Django?

How to create a series of buttons in JavaScript which can be clicked to do different versions of the same function?
I am making a website with Django to provide students with a spelling test which they fill out and then receive a mark out of 10. The students cannot be allowed to see the words so I have given them a series of sound bytes using the function 'speak()', only when I press the buttons they all say the same thing because I don't know how to parse the individual data to the function to tell it which spelling to "speak". I know that the reason why it isn't working is because I'm parsing "sBite.id" to the speak() function, and sBite.id will always be the same value. I just don't know what value I should parse in order to send the correct spelling to the function Here is the relevant JS code: function speak(word){ var msg = new SpeechSynthesisUtterance(usedWords[word]); window.speechSynthesis.speak(msg); } usedWords=[]; function load(played, mistake, score){ alert(mistake) var x =["ball","racket","apple","cheese","find","any","new", "display","please","happy","plead","pleat","aple","bple","cple"]; var step; var spellList = document.getElementById("spellList"); if(listlen < 10){ for(step = 0;step < 10;step++){ li = document.createElement("li"); sBite = document.createElement("button"); rand = x[Math.floor(Math.random() * x.length)]; if(usedWords.includes(rand)){ step = step - 1; continue; } else{ usedWords.push(rand); li.appendChild(document.createTextNode(rand)); li.id = "spelling"; spellList.appendChild(li); var testy = usedWords[step]; sBite.setAttribute("onClick","speak(sbite.id)"); sBite.type="button"; sBite.id=step; sBite.textContent=sBite.id; spellList.appendChild(sBite); … -
Django Rest Framework: File upload request header and webkit boundary included in saved file using FileUploadParser
I'm currently trying to build out a an application with both client-side and server-side code. My frontend is built in React, with my backend being Python/Django, utilizing django-rest-framework. The feature I'm building out now is a file-upload feature, which utilizes the Dropzone.js library in order to save and store files on the server. Eventually I'd like to be routing the files to AWS S3, but I'm not quite there yet. My views.py file is currently accepting and saving the file, however the webKitBoundary and file information are also being saved in the file. Optimally, I'd like to be saving the file without having to do file manipulation in order to trim out the unnecessary information. Here's my views.py: class SaveFile(APIView): authentication_classes = (CsrfExemptJWTAuthentication, ) parser_classes = (FileUploadParser, ) def post(self, request, format=None): newFile = File() newFile.file = request.data['file'] newFile.save() return HttpResponse('file upload success') My file model: class File(models.Model): file = models.FileField(upload_to = 'files') def __str__(self): return self.file.name class Meta: db_table = "files" My test.txt: hello (.^-^), And the saved result: ------WebKitFormBoundaryySdQAcRrBj8kluZ5 Content-Disposition: form-data; name="file"; filename="yurrr.txt" Content-Type: text/plain hello (.^-^), ------WebKitFormBoundaryySdQAcRrBj8kluZ5-- I've found a similar question here: headers and boundary included in uploaded file django rest framework However when I try …
