Django paginator issue
I am currently working on a django blog and I've coded a search bar where you type something and, if there's any post that contains what you've typed in the title, it should appear all the posts. This part is perfectly well-written. However, there's an error with the pagination. As you'll see in the views.py. The maximum num of posts per page is 3. However, you can see there's four. However, the paginator detects there should be another page for the fourth posts. Here's an image that shows that. Here's the views.py: class ElementSearchView(View): elements_list = Element.objects.all() def get(self, request, *args, **kwargs): paginator = Paginator(self.elements_list, 3) page_request_var = 'page' page = request.GET.get(page_request_var) try: paginated_queryset = paginator.page(page) except PageNotAnInteger: paginated_queryset = paginator.page(1) except EmptyPage: paginated_queryset = paginator.page(paginator.num_pages) queryset = Element.objects.all() query = request.GET.get('q') if query: queryset = queryset.filter( Q(title__icontains=query) ).distinct() context = { 'query': queryset, 'queryset': paginated_queryset, 'page_request_var': page_request_var, } return render(request, 'periodic/search_results_table.html', context) And here's the html template: The pagination is at the end of the template. {% load static %} <html> {% include 'periodic/head_search.html' %} <body> {% include 'periodic/header.html' %} <br> <br> <div class="container"> <div class="row"> <!-- Latest Posts --> <main class="posts-listing col-lg-8"> <div class="container"> <div class="row"> <!-- post … -
Using Django REST framework with TCP Server socket
I am developing a web api using the Django REST Framework. At the same time, I am receiving stream data from IoT devices as an HTTP Post message. In this, I use tcp socket server in python. When I try to use these two things together, Django REST Framework does not work for HTTP requests, only the TCP socket works. How can I run Django REST Framework and TCP socket together? TCP Server Socket code here: class RFIDServer(Thread): def __init__(self, address="", port=8000): super().__init__() self.gateways = dict() self.tag_list = {} self.rfidData = dict() self.rfidDataLocker = Lock() self.address=address self.port=port self.socket_setup=False self.setup_socket() def setup_socket(self): try: self.sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) except: exit("Couldn't create a socket") try: self.sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) except: exit("Couldn't set socket options") try: self.sock.bind((self.address, self.port)) except: print("Couldn't bind socket to server address") self.socket_setup=True def listen(self): if self.socket_setup!=True: print("Socket hasn't been setup.

How to improve automated (every 3 sec) calls in celery-beat, celery-worker with Redis?
I use celery-beat, worker, and Redis as a broker to schedule tasks and call a specific function in the background. The interval for the call is 3 seconds, and I may have multiple calls every 3 seconds. def theFunction(arg1, arg2): obj = Model.objects.get(id=arg1) # call to a Modbus server result = Modbus.call(ip=obj.ip, obj.port) # just an example Data.objects.create(value=result) I have set from the Django administration with celery-beat-schedule, all the tasks to call this function with a different id. I use supervisor to automate the commands separately: celery -A project worker --log-level=info celery -A project beat --log-level=info The server is 16GB of RAM, when Redis is running it consumes up to 14GB of the RAM and the server becomes slow. When I use celery purge to kill all tasks, I sometimes see more than 1 million tasks in the queue. How to improve that, to have a result every 3 seconds to display live data in a graph. In case there is another technology that I can use, let me know. -

Django models and managers circular import error
so In my project I have two directories: managers and models. here's my code: how I've imported objects around. I also use objects as typehints, for example: @classmethod def get_overwrite_objects(cls, parent_object: DataSheetsCluster): return parent_object.roles models/data_sheets.py from django.db import models from django import dispatch from api_backend.managers import (FieldDataManager, RolesManager) ... managers/positions.py from django.db import (models, transaction) from api_backend.models import (Role, DataSheetsCluster, DataSheet, DataSheetField, DataSheetsCategory) ...

Rendering markdown inside of <textarea> adds newline
I am implementing a Wikipedia-like webapp with Django. Data for the different entries is stored in Markdown files on the server. I use markdown2 for the conversions. Everything works just fine but I run into a problem when I try to edit an existing entry. The server serves "edit.html" to the client, passing a django form populated with the existing data. views.py class EditPageForm(forms.Form): title = forms.CharField(widget=forms.HiddenInput, label="title") content = forms.CharField(widget=forms.Textarea, label="content" def edit(request): if request.method == "POST": form = SearchForm(request.POST) ## a form with only a "title" input if form.is_valid(): title = form.cleaned_data["title"] content = util.get_entry(title) ## read the existing file.md form = EditPageForm(initial={ "title": title, "content": content }) return render(request, "encyclopedia/edit.html", { "title": title, "form": form }) edit.html <h1>Edit content for "{{ title }}"</h1> <form action="{% url 'save' %}" method="post"> {% csrf_token %} {{ form }} ## undesired newlines added here <input type="submit" value="Save"> </form> When the browser renders the textarea which includes the data to be edited, newlines are inserted without my consent. This behaviour loops everytime I edit a text so that more and more newlines are added. I don't really understand what is going on. Does anyone have an idea? -

I got Google SMTPAuthenticationError when I send email via django with NON-gmail smtp server, even though I don't use smtp.gmail.com
I'm running a website made with django. This website has a contact form, and when you submit, you and administrator will receive an email. message = render_to_string('email/contact_us_message.txt', context) send_async_mail.delay(_('subject'), message, settings.DEFAULT_FROM_EMAIL, [contact.email]) message_for_admin = render_to_string('email/contact_us_message_for_admin.txt', context) send_async_mail.delay(_('subject'), message_for_admin, settings.DEFAULT_FROM_EMAIL, [settings.ADMIN_EMAIL]) I used to subscribe to gsuite and use that smtp server. There was no problem sending and receiving emails. I decided to use another email hosting service two days ago, so I modified my dns record, canceled gsuite and deleted my account. The new email hosting service worked fine in the local environment. However, in production, email can't be sent sometimes. When I check the task results of celery results, it says 535, "b'5.7.8 Username and Password not accepted." I understand that this error message is displayed when connecting to the google service. For example, the app password is not set. But I don't use smtp.gmail.com or services related to google anymore. EMAIL_URL=smtp+tls://no-reply@mydomain.com:password@new-smtp-server.com:587 so I don't understand why I get this error message. Since I changed the dns record and it's been a little while, do I get this error related smtp.gmail.com? If I wait and the dns cache will be updated, will the error disappear? -
django common templates for apps with variables

Query elasticsearch using django-elasticsearch-dsl without PostgreSQL connection
I've a first django project with PostgeSQL and elasticsearch 7 running and indexes updated automatically thanks to the django-elasticsearch-dsl library. Now I would like to query (GET search only) the elasticsearch indexes from another django project. I copied the models and the documents.py.
