Translate Dockerfile from python-alpine to python-slim-buster (debian-based)
I am trying to improve the Dockerfile we use for deploying a Django-based app at work and first thing I would like to do is change the base image of python from alpine to slim-buster but I have to translate it to a debian-based image. I would like some suggestions on how I could translate it since I have zero to none experience with alpine. This is the original snippet from Docker. FROM python:3.8.6-alpine3.12 RUN apk update && \ apk add --virtual build-deps gcc g++ musl-dev && \ apk add postgresql-dev vim bash nginx supervisor curl && \ apk add libffi-dev && \ apk add --update npm && \ apk add git make cmake -
Chat message in Django-Channel not broadcasting
I am working with django-channels. I created a consumer to broadcast a message. The strange thing is that after opening 2 windows to see the broadcast, the below happens. The message is displayed on the last refreshed window (the number of message coincides with number of windows opened). But the message never gets to displayed on the other windows. channels==3.0.3 channels-redis==3.2.0 Django==3.2.3 Below is my consumer.py class EchoBroadcastConsumer(SyncConsumer): def websocket_connect(self, event): self.room_name = 'broadcast' self.send({ 'type': 'websocket.accept', }) async_to_sync(self.channel_layer.group_add)(self.room_name, self.channel_name) print(f'[{self.channel_name}] - You are connected!') def websocket_receive(self, event): print(f'[{self.channel_name}]- You are have received {event["text"]}') async_to_sync(self.channel_layer.group_send)( self.room_name, { 'type': 'websocket.message', 'text': event.get('text') } ) def websocket_message(self, event): print(f'[{self.channel_name}] - Message Sent {event["text"]}') self.send({ 'type': 'websocket.send', 'text': event.get('text') }) def websocket_disconnect(self, event): print(f'[{self.channel_name}] - You are have Disconnected') async_to_sync(self.channel_layer.group_discard)(self.room_name, self.channel_name) Below is my frontend (JS) const url = 'ws:127.0.0.1:8000/ws' + window.location.pathname; const ws = new WebSocket(url); ws.onopen = function(event){ console.log("Connection is Open"); } ws.onmessage = function(event){ console.log("Message is received"); const ul = document.getElementById('chat_list'); var li = document.createElement('li'); li.append(document.createTextNode(event.data)); ul.append(li); // var data = JSON.parse(event.data) //li.append(document.createTextNode( // '['+ data.username+ ']:' + data.text //)); ul.append(li); } ws.onclose = function(event){ console.log("Connection is Closed"); } ws.onerror = function(event){ console.log("Something went wrong"); } const message_form = document.getElementById('message_form'); … -

In Django, how to create file field database variable in a query?
I know how to create a simple query variable in views.py But I don't know what it represents. As for an instance there is a CharFiled in models.py (model name being Information) named age. And to store a single row's data in a variable one could use either var1 = Information.objects.order_by('-id')[:1] OR var2 = Information.objects.order_by('-id')[:1].get() From this what I'm understanding is that in var1 stores the queryset list and var2 stores the actual object. Please correct me if I'm wrong. Does it mean the var2 has the actual value of the age parameter from the database? If not, then var2 just point to that location? Moreover, let's say there is a FileFiled called userfile in the models.py along with age and that takes in the any file user wants to store on the DB. Let's assume the file is uploaded through the form and the whole uploading function is working just fine. Now I want to reduce the userfile into half, so for that I need to store the file's data in a variable at first. Can I do file_data = var2.userfile or file_data = var1.userfile? Again, what will be in file_data? Path to the file in DB or the … -
Localization_fields: as per Django Documentation & tutorial still gives error
I am practice on Django documentations on ModelForms and copying it as mentioned in docs still getting error Please advise what is wrong here As per Django Docs By default, the fields in a ModelForm will not localize their data. To enable localization for fields, you can use the localized_fields attribute on the Meta class. Code is as follows >>> from django.forms import ModelForm >>> from myapp.models import Author >>> class AuthorForm(ModelForm): ... class Meta: ... model = Author ... localized_fields = '__all__' If localized_fields is set to the special value '__all__', all fields will be localized. Error is as follows ile "/Users/rishipalsingh/Projects/notes/mdndjango/venv/lib/python3.9/site-packages/django/forms/models.py", line 250, in __new__ raise ImproperlyConfigured( django.core.exceptions.ImproperlyConfigured: Creating a ModelForm without either the 'fields' attribute or the 'exclude' attribute is prohibited; form AuthorForm needs updating. -
What is the proper way to add authentication to my django-react blog app
I have my blog app using Django in the backend and React on the front. I want that only an authenticated user can do some actions such as delete and edit articles on the front end.

Minor trouble installing mod_wsgi into venv
I thought this question would help me understand my file system and how mod_wsgi installs on my macOS (even though i am also stuck). Simply i am experimenting with django and apache. i have two different django projects (very basic tutorials) with venv's and one basic web app in each. I have pip installed mod_wsgi into one and it has added the package to the venv successfully and runs fine. When i tried the other venv it replied: - Requirement already satisfied: mod_wsgi in /Users/mjwallis/opt/anaconda3/lib/python3.7/site-packages (4.8.0) I must have installed mod_wsgi more globally prior in this case (can't remember what i did).
