A Django Issue when testing my website with a dropdown
I am following the tutorial at Django Tutorials. The goal is to get a dropdown list to display a logout when I click on it.

uwsgi/nginx doesn't respond until subprocess is done
I have server with nginx the passes http trafic to uwsgi runnig my django app. the django view I'm calling is creating a subprocess that runs the following test.sh bash script: #!/bin/sh echo hello sleep 10 echo morning for some reason I am not getting the 200 response from the view until the bash is done, i.e. "morning" is printed, although subprocess supposed to create a thread that run in parallel. While trying to debug this issue I noticed that if I cURL locally from server while running django directly with python manage.py runserver or when running uwsgi with http=127.0.0.1:8000 I get the 200 response before the "morning" print as expected. Any ideas why with socket=127.0.0.1:8000 and nginx it behaves different? my nginx is configured to pass http trafic to django: upstream django { server 127.0.0.1:8000; # for a web port socket (we'll use this first) } server { listen 80; location /api/ { uwsgi_pass django; include /path_to/uwsgi_params; # the uwsgi_params file you installed } } my uwsgi ini: [uwsgi] socket=127.0.0.1:8000 module=my_module.wsgi:application chdir=/project_dir master=true vacuum=true logger=file:/log_path stats=/tmp/uwsgi_stats.socket single interpreter=true and my view.py is: from subprocess import Popen from rest_framework import views from rest_framework.response import Response class TestApi(views.APIView): def post(self, request, … -

How to save the position of draggable elements?
Hello, I am making a web application in django, what it allows you to do is drag elements on the page, what I want to do is save the position of these elements so that when the page is reloaded the elements remain in the same position in which they left, is there any way to save the position? This is my javascript to drag elements. <script src="http://threedubmedia.com/inc/js/jquery-1.7.2.js"></script> <script src="http://threedubmedia.com/inc/js/jquery.event.drag-2.2.js"></script> <script type="text/javascript"> jQuery(function ($) { $('.drag') .click(function () { $(this).toggleClass("selected"); }) .drag("init", function () { if ($(this).is('.selected')) return $('.selected'); }) .drag(function (ev, dd) { $(this).css({ top: dd.offsetY, left: dd.offsetX }); }); }); And this is the element or elements that are dragged, the number of elements is variable since it is conditioned by a database. <div class="drag"> <span class="dot" title="{{ device.device_name }}" style="background-color: #197f32"><br/><b><p style="color: #ce3830;"> {{ device.device_name }}</p></b></span> </div> -

Adding Data to Request in Django REST Framework in Authentication Class
Suppose I have the following Authentication class in DRF. If the request is authenticated, then I need some additional data in the request object. Say, REQUIRED_DATA is that variable. class MyAuthClass(BaseAuthentication): def authenticate(self, request): # suppose is_authenticated_request and authenticated_user are methods # which return the responses as described by their name if is_authenticated_request(request): user = authenticated_user(request) request.REQUIRED_DATA = some_variable_of_any_type return (user, None) raise exception.AuthenticationFailed(_('Authentication failed.')) Here is how I used it in the viewset. class MyViewSet(viewsets.GenericViewSet): authentication_classes = [MyAuthClass] permission_classes = [permissions.IsAuthenticated] def create(self, request, *args, **kwargs): ############# # ......... # request.REQUIRED_DATA # using variable # ......... # ############# Am I going right? I need this variable after the request is authenticated. Is their a better way to do this? Middleware is one but Middleware runs for each request, I need for this viewset only. -
Git Heroku Django - Git pull heroku master not pulling rolled back version?

How to unittest Django Rest Framework endpoint with XML?
I've got an endpoint which I built with Django Rest Framework. It works great when I test it with something like Postman, but my unit tests fail. When I test my json endpoints I always post Python dicts instead of json strings, like this: response = self.client.post('/json-endpoint/', {'a': 1}, format='json') When I test the xml endpoint I tried to post a raw xml string like this: response = self.client.post('/xml-endpoint/', '<?xml version="1.0" encoding="UTF-8" ?><myDataStructure></myDataStructure>', format='xml') But this doesn't work. In my Viewset I override the create() method, and in there, my xml somehow seems to be "packaged" into another xml. If I print out request.body in the create() method I see this: b'<?xml version="1.0" encoding="utf-8"?>\n<root>&lt;?xml version="1.0" encoding="UTF-8" ?&gt;\n&lt;myDataStructure&gt;\n etc.. As you can see my xml is somehow encoded and then packed into another <?xml version="1.0" encoding="utf-8"?>\n<root>. Does anybody know how I can properly provide the xml when I write unit tests for the xml endpoint? All tips are welcome! -
