Template Does Not Show Me Anything When I Use A For Loop In Django
I want to show some items in my cart template, but it doesn't show me anything. When I don't use a for loop, it works fine, but it shows me nothing when I use it for a loop. My guess is, maybe something on my Cart class is wrong, I am not sure, but it would be great if you check it out.

Django Channels + WebSockets: concepts unclear
I have some experience with Django and am currently working on a project for live boardgaming (generally two-player abstract games). I am using Channels and am able to send moves to different tabs in the browser. Now I need to solve the issue of separating players from spectators, since they all go into the same "room" and even the third tab/user can make moves. I don't grasp all the concepts around Channels, layers, sockets, consumers, and so on, and am looking for some help or direction. Basically, I need some guidance on what the general structure of a project like this should look like. What should the consumers be? One for every user? One for every specific game between two players? One for every room? I've read that consumers are in a way equivalent to views, but it seems that one view can communicate with many consumers. I have tried to hold data in a consumer class, such that it is accessible to all instances of that consumer. It does not work, so I guess that's not the correct approach. Where do I store, say, the state of the board? Should I be writing every move and chat message to … -
Send Emails with html_message
I want to send HTML-email, using Django templates like this: <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> Hello <strong>{{ message }}</strong> - your account is activated. </body> </html> Also I want to send data from the backend with the Email. In this example I want to send a message from the backend with the email template. Here is my View: def home(request): message_name = "NAME" message_email = "EMAIL" message = "USER" msg_html = render_to_string('email/email.html') send_mail( 'message from ' + message_name, # subject message, # message message_email, # from email ['myemail@outlook.de'], # To Email html_message=msg_html, ) context = {'message': message, 'message_name': message_name, 'message_email': message_email} return render(request, 'email/email.html', context) When I receive the Email I only get the text and not the {{ message }} which would be USER in this example. -
Is it possible to use FCM-Django with a python client?(Firebase Cloud Messaging)
I am new to django and I need to write a REST api that can handle a database includes users with multiple IoT devices(Jetson Nano) belongs to user. User can set configuration settings of IoT device from web or mobile apps and I want to send notifications to the device when a change occurs. Is it possible to implement with FCM-Django? I think using a python client with an event listener at the Jetson side will do the work but I just wanna make sure if this plan works. I hope my question is clear. -
Print data in pdf from Django Admin Console action
I have a Django app which allows customers to register for an event and sign a liability release agreement. I want to be able to pick certain release agreements for each specific event and create a pdf file which can then be downloaded and printed. I wan to do this in the Admin console, probably using admin actions ('With selected, print release Form'). Does anyone know how I can get an Admin action to access field data, populate a pdf file and then make it downloadable? In my models.py file the Release Form model is: class ReleaseForm(models.Model): FORMSTATUS = ( ('required', 'required'), ('submitted', 'submitted'), ) customer = models.ForeignKey(Customer, on_delete= models.CASCADE, null = True) i_agree = models.BooleanField(default = False) release_status= models.CharField(max_length=200, null=True, choices=FORMSTATUS,default='required') release_date_submitted = models.DateTimeField(null=True,blank=True) note = models.CharField(max_length=1000, null=True,blank=True) def str(self): return self.release_status In my admin.py file I have added: @admin.register(ReleaseForm) class ReleaseAdmin(admin.ModelAdmin): def participant(self, obj): return str(obj.customer.last_name) + ", " + str(obj.customer.first_name) def training(self, obj): return str(obj.order.training_registered.name) def print_release(self, request, queryset): #code to print out the release forms needs to go here # or a call to function which does it updated=queryset.count() self.message_user(request, ngettext( '%d Relase Form was successfully printed.', '%d Relase Forms were successfully printed.', updated, ) % … -

Why does Django send different csrf tokens when using use_token function?
I have a ReactJS application deployed on one domain(abc.com) and a Django server is deployed on another domain(xyz.com). I have added a separate call to get the csrf token in Django as follows- def csrf(request): return JsonResponse({'csrfToken': get_token(request)}) When i call this API i get a Set-cookie response header which has a different csrftoken value as the json response from this API- Set-Cookie: csrftoken=0b6qbRmAyF8QITIHbvFT2gGFOB98Vzg7cCRWvFWn2zzRbLon4BduX3P0orRX5Afh; expires=Tue, 01 Mar 2022 10:33:18 GMT; Max-Age=31449600; Path=/; SameSite=None; Secure Whereas the response has the following csrf(which i save as cookie)- {"csrfToken": "mMPB6X86ZzsS6T2rg1AN0e8MhG9raEn6ydA7qLITttTTzLI7978oV1h7RwRgkFmg"} i need to send the csrftoken in the post call as well as a cookie and i cannot access the token sent in the cookie because it is of different domain (CORS) and neither can i overwrite that record. If i set credentials: 'include', in my fetch call and send the csrftoken in form data or as a request header(X-CSRFToken) then the call has the cookie sent to me as the cookie itself (0b6qbRmAyF8QITIHbvFT2gGFOB98Vzg7cCRWvFWn2zzRbLon4BduX3P0orRX5Afh) and the header/form data csrf as the one sent as json(mMPB6X86ZzsS6T2rg1AN0e8MhG9raEn6ydA7qLITttTTzLI7978oV1h7RwRgkFmg) and i get a 403 error with the message- CSRF verification failed.

How to allow reversing to one of two matches in urls.py?
I want my users to access a specific location of my API using either the English word "series" or the French equivalent "séries" as an argument in the URL. The URL and subsequent extensions will be reversed to using the English word. Here is my first attempt: urlpatterns = [ path(r"series/", include("series.public_urls", namespace="series")), path(r"séries/", include("series.public_urls")), ] Despite the following warning, I have been able to reverse all my URLs so far: ?: (urls.W005) URL namespace 'series' isn't unique. You may not be able to reverse all URLs in this namespace However a warning is a foreboding of impending doom and I'm looking for another solution. I've tried using Regex paths: urlpatterns = [ re_path(r"s(e|é)ries/", include("series.public_urls", namespace="series")), ] This throws an ImproperlyConfigured error. I understand the reverser cannot handle the "or" matching control but needs to know which of e or é it should reverse to. How can I allow reversing to "series" solely within this very urls.py file? -
Exception...NoReverseMatch ...Reverse for 'venue' with arguments '('',)' not found. 1 pattern(s) tried: ['venue/(?P<pk>[0-9]+)$']
I'm trying to develop a Django app for a booking system. I know the problem is from the url link pk argument that was passed to the venues.html. I've tried everything possible to solve this problem and nothing has worked. In venues.html, I've tried <li><a href="{% url 'booking:venue' pk %}">v.venue</a></li> <li><a href="{% url 'booking:venue' pk=v.pk %}">v.venue</a></li> - This shows me a list of all my venues as v.venue and only the first integer works (I hope this makes sense). <li><a href="{% url 'booking:venue' 1 %}">v.venue</a></li>- This shows a result similar to the previous one I just mentioned. Every other argument I've tried has given me the same error... I've read the django documentation on class-based detailview and watched and read a number of tutorials but nothing has helped. From everything I've found, the code I've written is supposed to work... However, I keep getting this traceback error. Pls, I would really appreciate any help I can get. Thank you so much.

How can I connect the user to a post he created in Django
I am starting with Django, and I have a question about the connection between a post and the user who created it. For now, I managed to create the link, however, whenever I create a new post, the user id is always the default one, thus one. I want to make it in a way that the user id is the id of the person creating the post, and for some reason, it never works. The other option I tried is to put "user" into the form but the problem is that then the user can choose which user he is, which is risky. So is there any way to make it automatic? That when the post is created, the right user id is directly connected to it?
