How to place cursor at end of text in input field after form submission using html and javascript?
I've created a text input form in html that sends user input words via POST method to Django views.py file. Here is the code for this form <form method="POST" action="search"> {% csrf_token %} <input type="search" name="search" value="{{form.search.value}}" placeholder="Search here..." autofocus x-webkit-speech/> </form> The value attribute takes the value returned by Django after a submit. Here is the code of my Django views.py file: from django.shortcuts import render import requests from bs4 import BeautifulSoup as bs from search.models import MyForm def index(request): return render(request, 'index.html') def search(request): if request.method == 'POST': search = request.POST['search'] form = MyForm(request.POST) max_pages_to_scrap = 15 final_result = [] for page_num in range(1, max_pages_to_scrap+1): url = "https://www.ask.com/web?q=" + search + "&qo=pagination&page=" + str(page_num) res = requests.get(url) soup = bs(res.text, 'lxml') result_listings = soup.find_all('div', {'class': 'PartialSearchResults-item'}) for result in result_listings: result_title = result.find(class_='PartialSearchResults-item-title').text result_url = result.find('a').get('href') result_desc = result.find(class_='PartialSearchResults-item-abstract').text final_result.append((result_title, result_url, result_desc)) context = {'final_result': final_result, 'form':form} return render(request, 'index.html', context) else: return render(request, 'index.html') When I submit the form, the value of the input field is well preserved but the cursor goes from the final position to the initial position. To solve this problem, I inserted a javascript script created in this article, in my index.html file … -

Django broken response with file data
In my project I use AWS S3 Bucket for media files. Project contains media_app application, that provide get and post requests to files in remote storage (all requests go through server, so media_app is kinda proxy between frontend and AWS S3. Today I faced with problem. When I try to get media file from AWS S3, Django correctly download it from remote bucket, save it in /tmp/ dir, get correct response metadata, but response itself is broken: it cause infinite response "in progress" state on frontend side (Tried with Postman and Swagger). "In progress" means "frontend application wait until response will be recieved", but on backend side there is no infinite loop. Django can provide next responses even if I use dev test server (Is is means, that no workers are blocked, cause django test server have only one worker). Information about request and response (Django Silk): There is a part of my view, that provide image download: from django.http import Http404, StreamingHttpResponse from wsgiref.util import FileWrapper class ImageDetailAPIView(DetailDownloadAPIView): queryset = Image.objects.filter(is_soft_deleted=False)\ .prefetch_related('thumbnails') serializer_class = ImageSerializer @swagger_auto_schema(responses=image_detail_responses) def get(self, request, *args, **kwargs): try: instance = self.get_object() except Http404: raise FileNotFoundException service = ImageDownloadService(instance) chunk_size = 8192 file_path, status_code = service.download() … -

Render Django Template after AJAX POST
I'm using django and ajax to build a small app. I send some data by ajax: // send search post when clicking the button $("#search-button").click(function(){ $.post( "{% url 'search-index' %}", { query: $("#query").val() }, function(data, status){ console.log("success") } ) }) And I generate some new data according to the query, which I'd like to display in the html template: def view(request): if request.method == "POST": query = request.POST["query"] hits = search(query) return render(request, "search/index.html", {"hits": hits}) {% if hits %} <div class="container"> {% for hit in hits %} <div> <a href="">{{ hit.title }}</a> </div> <div> <p>{{ hit.abstract }}</p> </div> {% endfor %} </div> {% endif %} However, I find django is not rendering the template, I got an empty html page after this post request. I don't want to append the data using jquery. I prefer to modify the html in the template. Any solution? Thanks in advance. -

TimeoutError while sending mails
I have a Django project where the users can launch a task that's executed using Celery, and then they receive a mail when this task is finished. My issue lays in my mails that are not sent everytime. Some emails are not sent and in the console I have a TimeoutError: [Errno 10060] WSAETIMEDOUT. I don't know if that can help but I noticed that when I start trying to send mails, the first ones raise this error, and after some time of trying to send mails, like maybe 15mn, the mails are sent successefully and I get no error afterwards. I've tried every solution I was able to find here on SO as well as on GitHub, but none of the solutions provided seemed to work for me. I'm using gmail with a double authentication.

how to send an email verification from admin when an email is updated
I joined a project where the code is written on django 2+. It's a system for patient and doctors. When a doctor registered a patient, this one gets an email confirmation with a link. Once he clicks on it she can use the platform. On her user interface in settings, a patient can update her email and she will get a new link to her new email to confirm that it is her email. Before she clicks on the confirmation link, the email attribute is not changed. only the email candidate is updated and to this one the email is sent. (if I change the email attribute to the email_candidate one so if she made a mistake on the her email_candidate she won't be able to log in anymore) Then after the click, the patient email will become the email candidate one. All this works on the Patient Support Admin interface, an agent can help patients to update their email also. But when the action is requested of send an email confirmation the email candidate is not chosen. only the user email is chosen and to it the email confirmation is sent. I really don't understand how to call maybe … -

Use viewset and serializer without model
I want to return the CPU usage and Memory usage by viewset. class StatusViewSet(viewsets.ViewSet): serializer_class = StatusSerializer def list(self, request): // get CPU/Memory usage here somehow. below line is dummy. status_data= {"memory":80,"cpu":80} serializer = StatusSerializer( instance=status_data, many=True) return Response(serializer.data) class StatusSerializer(serializers.Serializer): cpu = serializers.IntegerField(read_only=True) memory = serializers.IntegerField(read_only=True) What I have done is like this below.

Django - separated settings by environment. Not finding variable from base settings

In settings/test.py I have DATA_VOLUME_BASE_DIR = BASE_DIR / 'scanned_images'.
