Django StreamingHttpResponse ConnectionAbortedError
I've tried to use django to stream my camera and it does work well. But when I close the web page in my browser, django starts to throw errors. I've tried try except but doesn't work. Is there some way that I can do to at least prevent django from crashing and make it work normally? Here is the code(omit the import sentences): class VideoCamera(object): def __init__(self): with open('config.json', 'r') as f: conf = json.load(f) self.video = cv2.VideoCapture(conf['rtspURL']) def __del__(self): self.video.release() def get_frame(self): success, image = self.video.read() return image def gen(camera): while True: frame = camera.get_frame() ret, jpeg = cv2.imencode('.jpg', frame) yield (b'--frame\r\n' b'Content-Type: image/jpeg\r\n\r\n' + jpeg.tobytes() + b'\r\n\r\n') @gzip.gzip_page def video_feed(request): return StreamingHttpResponse(gen(VideoCamera()),content_type="multipart/x-mixed-replace;boundary=frame") def monitor(request): return render(request, 'monitor.html') And here are the errors throwed: Traceback (most recent call last): File "C:\Environment\Anaconda3\lib\wsgiref\handlers.py", line 138, in run self.finish_response() File "C:\Environment\Anaconda3\lib\wsgiref\handlers.py", line 180, in finish_response self.write(data) File "C:\Environment\Anaconda3\lib\wsgiref\handlers.py", line 279, in write self._write(data) File "C:\Environment\Anaconda3\lib\wsgiref\handlers.py", line 453, in _write result = self.stdout.write(data) File "C:\Environment\Anaconda3\lib\socketserver.py", line 775, in write self._sock.sendall(b) ConnectionAbortedError: [WinError 10053] An established connection was aborted by the software in your host machine [12/Sep/2018 11:19:06] "GET /monitor HTTP/1.1" 500 59 ---------------------------------------- Exception happened during processing of request from ('127.0.0.1', 11826) Traceback … -

How do I differentiate between Django messages in templates while using nested modals?
So I've racked my brain for about 2 days now trying to figure out how to get this to work, and even the cheap work-arounds have failed, or have introduced other problems. At the heart of my issue, I believe, I have nested modals and a custom bootstrap form in both: the first for login, and the second for signup. Let's assume in one case I want to do all my validations server-side, and possibly get full control over each of the error validation messages, as well as how and where they should appear respective to their input. How do I do that using django.contrib.messages? If could use some of Bootstrap 4's built-in methods for validation as a first line of defense, or data-validate-on-blur to work like how it does with Zurb Foundation's Abide, even better. As it stands, and with the various work-arounds I've found on Stack Overflow, i.e. using jQuery to toggle the modal (not the prettiest as it reloads the page), the best I've been able to do still bleeds my messages in between modals and/or my redirect views. I've read threads on how to clear Django messages, and thought that might be a fix, so if … -
django model field depend on the value of another field
The use case of my application is I will have various fields to fill and among them one is Industry field and another is Segment Field for brand. The industry field is like category that brand falls into. So, if i choose the industry as Health Care for XYZ brand then the segment field should show the items like 'Ayurveda', 'Dental Clinics' (all health care related items). Basically, its like sub-category. Here is a sample model class Industry(models): name = models.CharField() # value will be filled from admin side class BusinessModel(models): industry = models.ForeignKey(Industry, blank=False, null=False, related_name='industry', on_delete=models.CASCADE) # segements = models.ForeignKey() total_investment = models.CharField() # will be choice field This is a simple model and I have not created Segment model as I am not sure how to approach to this problem. I am just curios to know, if for such case, do i have to something special in models.py or in the view side. Such type of things get arise during development phase, thus, I want to be clear on problem solving pattern in django. -
Django - is possible to use function views that are not registered in URL.py as pure functions?
I have a Add to Cart button in a detail view. It works fine, but the problem is I don't want it to redirect to any other page after I add some books to my cart. I just want it stay in the current page. Also is possible to just make a function somewhere which can be called by the button? book/templates/book/detail.html: <form method="get" action="{% url 'cart:add_to_cart' %}"> {% csrf_token %} <select name="quantity"> <option>1</option> <option>2</option> <option>3</option> <option>4</option> <option>5</option> <option>6</option> </select> <input name="bookID" value=" {{ book.id }} " hidden> <button type="submit"> Add to Cart</button> </form> cart/views.py: def add_to_cart(request): q = request.GET.get('quantity') book_id = request.GET.get('bookID') if book_id and q: <some code to edit BooksInCart model here> else: return BooksInCart.none() cart/urls.py: app_name = 'cart' urlpatterns = [ path('(I dont want it to direct', views.add_to_cart, name='add_to_cart'), path('<int:id>', views.ItemListView.as_view(), name='items'), ] -

Is it possible to missmatch opening and end tags in xml on purpose?
So, a few literary students tried to digitaly edit some text and unfortunatly they've ended up with a few hundred pages of <author> H.P.Lovecraft <authorEnd> <placeTime> Arkham <placeTimeEnd> I'm now writing a django application to shape those into something somewhat usefull. I do have a working function to check and replace them, but it's really clumsy and awkward. Now I'm wondering, if you could replace < /author> somehow with < /authorEnd> and use an xml-parse to process the whole thing. Thanks. -
how to use value for loop in text content in django
I have textfield value that is populated in by the user. I want to create my own "tag" of sorts so that when present, I can loop through its return value. Here is example of content that my be entered by the user: my awesome content starts (-- assets --) ending portion of my content I'm thinking a template tag would be used for this do something along the lines of: {{ mycontent|check_if_assets_present }} Then this would print something like: my awesome content starts Asset 1 Asset 2 Asset 3 ending portion of my content How can I accomplish this in a django template? -
Django: make stringed byte-string back to original
Good day. Now I make some application with new users model and email as login. And simple confirmation with users email. The plan is: User enters his or her data, email is first of course. Next He receives some code (formed as urlsafe_base64_encode(force_bytes(users_email))). This code is planned to be entered by hand or with copy-paste in confirm field. And users account is active. In python console this chain works good. The problem is: when user enters by hand or copy-paste the code from email raises DjangoUnicodeDecodeError with 'utf-8' codec can't decode byte... You passed in b'm\xb5\xa5\xad\xb... comments. Some analysis shows that in post function the code arrives as string "b'bla-bla-bla". But not as byte-string b'bla-bla-bla', which is good for getting original string with force_text(urlsafe_base64_decode(the_code)). Any ideas to convert the string object with b starting symbol to more comfortable byte-string object? Or there is another way to make some secret encoding/decoding based on user-name (user-email) ? Thanks anyway. -
Python3 Django: Getting Invalid Salt Error With Bcrypt
So was just trying to make a basic login and registration boiler plate with custom validations. But for some reason I am continuously getting an invalid salt error when it comes time to try and log in. Might I add, the way have my bcrypt set up has worked in prior projects.. But when I upgrade to Python3, for some reason it gets this error for me.. I started putting print statements throughout the entire app, and narrowed it down to my Login Form Validator.

Using asyncio.create_subprocess_shell within Django channels Consumer
Whenever a client (i.e. consumer) connects to my Django server, I want to execute a command in the command line: from channels.generic.websocket import AsyncWebsocketConsumer import asyncio class Consumer(AsyncWebsocketConsumer): async def do_command(self): process = await asyncio.create_subprocess_shell('sudo /bin/systemctl start ssh') await process.wait() print("command has finished") async def connect(self): asyncio.get_event_loop().create_task(self.do_command()) print("Finished scheduling do_command task") When I run the above code, I see that "Finished scheduling do_command task" is printed every time a client connects to my server. However, "command has finished" never gets printed. Why is that? The issue seems to be specifically with the await process.wait. For some reason, the command never finishes executing (i.e. process.returncode is always None). However, the following code works fine: import asyncio async def do_command(): process = await asyncio.create_subprocess_shell(cmd='sudo /bin/systemctl start ssh') await process.wait() print("Finished process.wait") print(process.returncode) loop = asyncio.get_event_loop() task = loop.create_task(do_command()) asyncio.get_event_loop().run_until_complete(task) loop.close() print("Finished Go Task") returns: Finished process.wait 0 Finished Go Task Why does "command has finished" never get printed? -
