RTSP on Django using OpenCV
I need to stream a surveillance camera onto a Django based website. I found a tutorial on Youtube but it is very simple. Down below is my code: from django.shortcuts import render from django.views.decorators import gzip from django.http import StreamingHttpResponse import cv2 # Create your views here. @gzip.gzip_page def Home(request): try: cam = videoCamera() return StreamingHttpResponse(gen(cam), content_type="multipart/x-mixed-replace;boundary=frame") except: pass return render(request, 'index.html') # Video Capture class videoCamera(object): video = cv2.VideoCapture("[user]:[password]@rtsp://[ip-address]:554/sub") while True: _, frame = video.read() cv2.imshow("RTSP", frame) k = cv2.waitKey(10) if k == ord('q'): break video.release() cv2.destroyAllWindows() However, I encounter an error: cv2.error: OpenCV(4.6.0) D:\a\opencv-python\opencv-python\opencv\modules\highgui\src\window.cpp:967: error: (-215:Assertion failed) size.width>0 && size.height>0 in function 'cv::imshow' Can somebody help me out? -
How to "save and continue editing" a task in django-viewflow
I'm building an approval workflow using django-viewflow and django-material. A key component of the workflow is for the end user to fill in a lengthy form and eventually submit it for review and approval. What I want My users will expect to be able to save and continue editing, so that they can fill in the form half way, save their progress, and come back later to complete the form filling. Only then they'll want to submit the form. This is a standard feature in the Django admin. What I've found In the default task.html template, django-viewflow offers two submit buttons (source): <button type="submit" name="_continue" class="btn btn-flat">{% trans 'Done and continue on this process' %}</button> <button type="submit" name="_done" class="btn primary white-text">{% trans 'Done' %}</button> The official docs are pretty slim on the difference between these two tasks. "Done and continue" marks the current task as done and activates the next task (which as a user I want to do by default, other than "save and continue editing"). "Done" seems to mark the current task as done, but doesn't proceed to the next task, which requires some awkward self-assigning to proceed. I can see how a user can get confused here. … -

How to setup nginx config .well-known/acme-challenge with a proxy to Django?
I am very confused with the Nginx .well-known/acme-challenge configuration and how it works with a proxy for Django. Here is my frontend config with is working: server { listen 80; server_name myserve.com; root /var/www/html/myapp_frontend/myapp/; index index.html; location / { try_files $uri$args $uri$args/ /index.html; } location /.well-known/acme-challenge { allow all; root /root/.acme.sh/; } return 301 https://myserver.com$request_uri; } server { listen 443 ssl; server_name myserver.com; location / { root /var/www/html/myapp_frontend/myapp/; index index.html index.htm; try_files $uri$args $uri$args/ /index.html; } ssl_certificate /root/.acme.sh/myserver.com/fullchain.pem; ssl_certificate_key /root/.acme.sh/myserver.com/privkey.pem; } So, on the frontend I have no problem to define: root /var/www/html/myapp_frontend/myapp/; Now I can run the acme script like this: /root/.acme.sh/acme.sh --issue -d myserver.com -w /var/www/html/myapp_frontend/myapp/ It is working fine. But I have issues with my Django backend because the nginx config uses a proxy: upstream myapp { server backend:8000; } server { listen 80; server_name api.myserver.com; location / { proxy_pass http://myapp; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $host; proxy_redirect off; } location /.well-known/acme-challenge { allow all; root /root/.acme.sh/; } return 301 https://api.myserver.com$request_uri; } server { listen 443 ssl; server_name api.myserver.com; location / { proxy_pass http://myapp; } ssl_certificate /root/.acme.sh/api.myserver.com/fullchain.pem; ssl_certificate_key /root/.acme.sh/api.myserver.com/privkey.pem; } Notice that I do not have a configuration for the folder "/var/www/html/myapp_backend/myapp/" as I have on the … -

How many create FCM topics in a server
My team was in trouble in push alarm with FCM token in IOS, So we decided to push alarm to each user with topics. I know that "One app instance can be subscribed to no more than 2000 topics." Firebase But i confused about "One app instance". Is that mean each android or ios application user can subscribe 2000 topics? or Each FCM Server can create up to 2000 topics? I wonder about One app instance's meaning in "One app instance can be subscribed to no more than 2000 topics" -
Got a `TypeError` when calling `Post.objects.create()`. This may be because you have a writable field on the serializer class that is
Writing a Django app which has a post table that has a recursive relationship to itself. This means that post CAN have a parent post (allows for replies). I want to ensure that a post can have a null for the parent post attribute - this would denote the "root" post. However, when I implement the views, model and serializer for the posts, I get the following error (stack trace): Got a `TypeError` when calling `Post.objects.create()`. This may be because you have a writable field on the serializer class that is not a valid argument to `Post.objects.create()`. You may need to make the field read-only, or override the PostSerializer.create() method to handle this correctly.

Override django setting only if present in os.environ
I want to define a function that will create a variable under certain circumstances at the scope of where the function was invoked. Something like this: def hook_env(new_var_name, env_var_name): if env_var_name in os.environ: "define new_var_name at the scope in which this function was defined and set it equal to os.environ[env_var_name]" My use case is so I can override Django settings from environment variables, but only present in the environment. Something like this is invalid # only create the variable if some criteria is met def hook_env(new_var, env_name): if env_name in os.environ: global()[new_var] = os.environ[env_name] In C/C++ I might use a macro.

I'm trying to print out the email related to a specific OrderItem for a Customer, even tho the email exists, it returns "None" instead, what part of my logic is wrong? #Models class Customer(models.Model): email = models.EmailField(max_length=150) class Order(models.Model): customer = models.ForeignKey(Customer) class OrderItem(models.Model): #View def test(): try: customer_email = OrderItem.objects.get(order__customer__email=['email']) except OrderItem.DoesNotExist: customer_email = None print(customer_email) -
Use Django Rest API to verify emails for new users in Flutter
We have made the email verification API thru Django, how do I implement it in Flutter? There are many tutorials using Firebase, but not many using Django. Thanks! I am expecting to use Django to send a verification email when a new user register an account -
Is it possible to send data from one form to multiple models in django using a normal form instead of multiple ModelForm?
I know it sounds weird, but I'm struggling a lot to show multiple tables with an inline, which populates three models with foreign keys, so I'm trying to find easier solutions than creating a script with JavaScript (which I don't know how to do) or a very complicated solution. My idea is to create a normal form with all of the fields and use it to fill all the models. class Order(models.Model): customer = models.ForeignKey("Customer", on_delete=models.CASCADE) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) paid = models.BooleanField(default=False) class Meta: ordering = ("-created",) def get_absolute_url(self): return reverse("sales:order-update", kwargs={"pk": self.pk}) def __str__(self): return "Order {}".format(self.id) def get_total_cost(self): return sum(item.get_cost() for item in self.items.all()) class OrderItem(models.Model): order = models.ForeignKey(Order, related_name="items", on_delete=models.CASCADE) product = models.ForeignKey( Product, related_name="order_items", on_delete=models.CASCADE ) quantity = models.PositiveIntegerField(default=1) def __str__(self): return "{}".format(self.id) def get_cost(self): return self.price * self.quantity class Customer(models.Model): first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50) phone = models.CharField(max_length=15, null=True) email = models.EmailField() address_line_1 = models.CharField(max_length=250) address_line_2 = models.CharField(max_length=60, null=True) postal_code = models.CharField(max_length=20) city = models.CharField(max_length=100) state = models.CharField(max_length=100, null=True) country = models.CharField(max_length=100, default="Mexico") def __str__(self): return f"{self.first_name} {self.last_name}" def get_absolute_url(self): return reverse("sales:modalcustomercreation") I only tried the first solution in [this stackoverflow question](https://stackoverflow.com/questions/5720287/django-how-to-make-a-form-for-a-models-foreign-keys) but It doesn't worked. -
ReactNative, Apollo and Django: upload files
I decided to learn such a technology as GraphQL. For this, I came up with an application (I develop it on ReactNative), a python backend (django-graphene). How the client chose Apollo. I set everything up, everything works, I even did a part already. And here I needed to upload a profile photo. The problem is that I haven't found a way to do this. I used to use the REST API and the client was axios. So I just took the FormData and passed it. Accordingly, the backend accepted and saved as usual. And here I don't even know where to start. I found the apollo-upload-client package, but I didn't find how to integrate it into ReactNative (more precisely, there is a description there, but I didn't understand how to use it correctly). I do it like this: const fileSubstitute = { uri: uriFromCameraRoll, name: "a.jpg", type: "image/jpeg", }; I found graphene-file-upload for the backend, it seems to see my files, but I don't know how to save them (by the way, I can transfer the file without apollo-upload-client). I really like GraphQL, but uploading files is a big deal. If I don't solve it, I will be forced abandon …
