Is there a way to serialize multiple objects in Django?
In a Django Project I would like to implement a simple chat-box. Version Django version 3.0.8 Models.py class DirectMessageClass(models.Model): sender = models.ForeignKey(User, on_delete=models.CASCADE, related_name='from_this') receiver = models.ForeignKey(User, on_delete=models.CASCADE, related_name='to_this') timestamp = models.DateTimeField(auto_now=True) content = models.CharField(max_length=200) read = models.BooleanField(default=False) def serialize(self): return { "id": self.id, "sender": self.sender.username, "sendername":self.sender.profile.firstname, "senderimage":self.sender.profile.image.url, "receiver": self.receiver.username, "content": self.content, "timestamp":self.timestamp.strftime("%m/%d/%Y, %H:%M:%S"), # to format date "read":self.read, } Views.py def loadbox(request): user = request.user # Return messages in reverse chronologial order messages = DirectMessageClass.objects.filter(receiver=user).order_by("-timestamp").all() return JsonResponse([message.serialize() for message in messages], safe=False) I successfully get messages and turn it into a JSON object in the /loadbox path with this method. Later on, I fetch this data to display messages and it works. Example of my /loadbox path [{"id": 1, "sender": "ekvatorcizgisi", "sendername": "Asli", "receiver": "bilge", "content": "hi", "timestamp": "09/02/2020, 08:22:26", "read": true}] However, because I want it to display as a dialog. I need to add also the reply messages in this JSON object. In views.py I try def loadbox(request): user = request.user # Return messages in reverse chronologial order messages = DirectMessageClass.objects.filter(receiver=user).order_by("-timestamp").all() # return replies sent by the current user replies = DirectMessageClass.objects.filter(sender=user).order_by("-timestamp").all() return JsonResponse([message.serialize() for message in messages], safe=False) I am not sure how to return multiple … -
Django Python - Variable seems to be getting cached?
Within my Django app I obtain a list of projects within our Google Cloud Organisation with the following: try: global projectdicts projectdicts = cloudresmanv1.projects().list().execute() projectdicts = projectdicts.get('projects') except Exception as e: logging.error(e) The above is taken from a Django form called ProjectForm. However, after I've created a GCP project and browse within my Django app to the ProjectForm page again, the list doesn't update to show the newly-created project. My understanding is that it should run the above again, regardless. If I run through the script manually, the projectdicts variable of course updates. So, this leads me to believe for some reason the Django app or Python is caching the variable and not bothering to run the above again. Is this a likely problem? And if so, how do I force Django/Python to re-run this part of the script again to ensure the list of GCP projects is updated whenever I browse to the ProjectForm page? -

I want to prefetch the fields for my list of objects in only 1 DB call. Is there an elegant way to populate my instance prefetch cache?

Django - Add Status 'Read' to messages
I have a django model Message which has sender, recipient, sent_at and a M2MField read. In the template when user Bob clicks on user Jane, their messages are loaded in and a view with the recipient's name (Jane) gets called to filters down Bob's messages and add Bob to Jane's message' read field. It works for the first 2 messages: Bob sends a message, Jane clicks on user Bob, Jane gets added to Bob's message' read field. Jane sends a message, Bob clicks on user Jane, Bob gets added to Jane's message' read field. But after the first message from Bob and the first from Jane it stops working. Here is the view: class ReadMXApiView(APIView): def get(self, request, format=None, *args, **kwargs): sender_ = self.kwargs['username'] myself = request.user my_mex = Message.objects.filter(recipient__username=request.user).filter(sender__username=sender_) if my_mex.exists(): if myself in my_mex.latest('sent_at').read.all(): return Response('No new messages from '+sender_) else: for m in my_mex: m.read.add(myself) return Response('I read the messages') return Response('No messages from '+sender_) Thank you for any suggestions -
How to add plain text to show up in my template using css?
I want to add plain text inbetween my CharFields or TextAreas that I created using Django and Css. I do not want to add the code in my template file but in my forms.py file. The final result should be like this: "I would pay _____ for this". Here, I can either include the first part of the sentence in the "label" of my CharField or I can include it in my FieldSet using "<h5..."etc. However, if I want to include the second part of the sentence which is "for this", it doesnt show up when I use the same structure with "<h5 .."etc. And I cant include another label.

URL pattern in django to match limited set of words
I have a URL pattern in Django where there is a variable (called name) that should only take one of a select list of words. Something like this: path("profile/<marta|jose|felipe|manuela:name>/", views.profile), So basically only these paths are valid: profile/marta/ profile/jose/ profile/felipe/ profile/manuela/ How exactly can I configure this in the Django url patterns? The above syntax tries to illustrate the idea but doesn't work. I've seen this ten year old question but that uses the previous format in the url patterns file so I imagine it should be done differently now...?
