Telegram image scraper
Hi, I have trouble with Telegram images scraper (I don't know how to call it). It's a feature that puts an image in chat via URL. (Screenshot below). But when I am trying to serv static files by Django or Flask Telegram really can't scrap that image. (Screenshot below) Also, I've tried NGINX server but seems similar. Did anybody know how that feature works or somebody tried to do that on their own? Maby I should register the domain? http://95.213.204.252/static/img_server/img/test.jpg -
Group level permissions in django
I have a list of custom permissions in the Permission model, a User model and a Group model. I have different set of permissions(from the Permission model) defined for each group. Each user belongs to a particular group. I want to include a permission check in my website such that whenever a user logs in and tries to go to a view, the back-end checks if the user has the permission to enter the particular view. How to implement this in my website? Note: I am not using django REST framework. -

I have a BookListView which displays all the books in my library. I have also a subclass of BookListView called BookSearchListView.

Django template renders {% trans %} strings in strange order
I'm working on supporting Arabic in a Django web database, and I'm encountering some very strange rendering behavior. Specifically I'm trying to reorder the words on the page from right to left, all of them being individually gathered strings in the template (either from a context variable or a trans tag). Hopefully these images will illustrate the problem clearly. English is the project default. Django version is 1.6. In English, everything is fine yields However in Arabic, the same markup results in this, with the cultural period block rendered at the end. But if I take that first trans tag out and replace it with a string like this the order is correct Now here's where it gets very strange. If I add some characters after the first trans tag (cp in this case), it renders correctly yields But if I add a character before the trans tag (a colon in this case), it gets split up in a very bizarre way yields I'm really hoping that there are some underlying rules that Django uses while translating that can explain this. I'm really hoping that it's not (as I'm theorizing) caused by a tiny lag in the time that translation … -
Django: Create and save a model using JSON data
Im building an app using Django 1.10 as backend and Angular 2 4.0 for frontend. Is it possible to create and save a model instance from a JSON data object?

How do you get daterangepicker input passed into django form?
I am almost completely new to Django and web development so please help me out. I pretty much just want to create a form on Django that takes in two dates(a start and end date) and a text input. I have tried everything to get daterangepicker into my program but I either get the daterangepicker to show up but unable to pass the html input back into the form or I can't get the daterangepicker to show up. Basically, I just want to allow the users to pick the two dates using a calendar instead so I guess I don't need to implement daterangepicker if it is not necessary. Here is what I have so far: views.py from .forms import HyugaRequestForm def create_req(request): name = request.user.username form = HyugaRequestForm(request.POST or None) if form.is_valid(): instance = form.save(commit = False) instance.name = name instance.s_date = form.cleaned_data.get('Start_Date') instance.e_date = form.cleaned_data.get('End_Date') instance.save() context = {'form':form,} return render(request,'timeline/hyuga_requests_form.html', context) forms.py from django import forms from .models import Hyuga_Requests from django.forms import ModelForm from django.forms.extras import SelectDateWidget class HyugaRequestForm(forms.ModelForm): Start_Date = forms.DateField(widget=SelectDateWidget) End_Date = forms.DateField(widget=SelectDateWidget) class Meta: model = Hyuga_Requests fields = ['reason'] models.py from __future__ import unicode_literals from django.db import models class Hyuga_Requests(models.Model): name = … -

Make runserver python to use multiple cores & know when code changes
I am using python manage.py runserver to run my django app. But I figured out that it, by default uses just one system core. In Gunicorn/Uwsgi I usually specify workers and threads but they take time to restart as workers are first killed and new ones are spawned after that. How can I do that directly in runserver? Assume I have to use runserver for my staging environment, I want it to use more resources and handle load. Or is there any other way to restart/reload the code without downtime? Or a way I can run Django via Gunicorn or UWSGI and make the restarts happen really quickly. If I change my code, while runserver is running, will it automatically know the code has changed? -
How can I handle the exception in Django 1.8.7
When I run the development server in Django, exception occurs as follows. ?: (1_7.W001) MIDDLEWARE_CLASSES is not set.
