DjangoCMS: disable login via http, force https
Our DjangoCMS site is accessible via http and https. Anonymous usage via http is ok. But I want to disable logins via http. Is there a way to force the usage of https as soon as the user wants to login? Even the login-page (with username and password fields) should not be available via http. Background: I don't want the password to go over the wire unencrypted. -

Python Class routing on data-flow processing
What is the most correct and "pythonic" way to deal with a class routing for many different type of objects. I have a data flow of many different json events that have to be processed, but every kind of event has a different json structure corresponding on a different class created to deal with it, what i want to do is to catch the event, read the descriptive field that identify the type e create a corresponding object with correct class, and with a wrapper catch all the values in the json structure, but not with an infinite series of " if....elif.........else". Any advice? Thank you PS it is inside a django project -

How would you make an Excel-like user interface with Django?
I am currently working on a project where the user wants the user interface to look like an Excel document. This is because the user normally writes data into an Excel document, and wants to switch to writing data straight into the user-interface instead. It should look something like this: In this project, so far, I have only used Django, and there was no need for using Bootstrap, for example. However, I would be willing to use a front-end framework in order to create this Exel-like user interface. Trying to make html-tables have been unsuccessful so far. Does anyone have suggestions on how it might be done? Thank you! -
Convert datetime to local time from Django Query to Openpyxl
Django converts the date time (I use timezone.now() to store in database) to local time in templates fine. What I need help on is when it is written to a cell in openpyxl. Right now, I simply assign the attribute of the query to the cell. query = SomeModel.objects.latest() date_recorded = query.date_recorded In templates, date_recorded is already converted to local time. No problem there. ws.cell(row=rows, column=cols).value = date_recorded The above code results to UTC. Please help me convert it to local time. Thank you. -

Django web app: how to save thousands of variables per user
There is a website driven by Django where the user logs in and can answer thousands of questions. I want to persistently save whether a given user has answered a given question or not. My approach so far is for the User table to have thousands of columns in the PostgreSQL database - a column for each question. I read there is a 1,600 column limit in PostgreSQL, which I haven't reached yet, but would reach eventually. What is a viable architecture for this kind of functionality in a web app? -

How to allow access only for kubernetes pods in postgresql?
I have a Django app running in Kubernetes in GKE. And that django app connects to a static (non-containerized) postgresql server. As both of them are located in one zone, my django app uses internal IP to connect to database. I want only my django app to request a connection to the postgresql database and deny connection for requests coming from other IPs. To do that, in pg_hba.conf I did this: host all all 14.133.0.0/24 md5 Because all internal IPs start with 14.133. However, the requests are coming from pod IPs and thus requests for connection are denied. An example for a Pod IP can be 14.4.123.32. So, if I do the following in pg_hba.conf, the problem will be fixed: host all all 14.0.0.0/8 md5 Another thing to note is that Pod IPs always change. So, this solution will break once the pod is updated. What is the best practice to go about this? -
Test asc for arg which is self
Test should give 400 status code, but it ascs for self as argument, but isn't it a mistake? This is test: def test_cab_number_does_not_exist(self): data = {"cab_number": "0"} self.client = self.Client url = reverse('api:orders') response = self.client.post(url, data) response_content = json.loads(response.content) cab_number = response_content['cab_number'] self.assertEqual(response.status_code, 400) This function gives mistake like: TypeError: test_cab_number_does_not_exist() takes exactly 1 argument (0 given) . I don't know how to fix it. -

Organizing a one-to-one relationships for checksums
Django==1.11.6 I'd like to collect checksums for uploaded files. I have done it via GenericRelation. This is clumsy.

Running multiple instances of daphne behind a load balancer: django-channels
I am using django-channels to add HTTP2 & WebSocket support for my application. I could not find a lot of documentation as to how to scale channels. Below is my nginx configuration that load balances multiple instances of daphne running on the same machine but different ports. Is this the correct way to do it? upstream socket { least_conn; server 127.0.0.1:9000; server 127.0.0.1:9001; server 127.0.0.1:9002; server 127.0.0.1:9003; } server { listen 80; server_name 127.0.0.1; location = /favicon.ico { access_log off; log_not_found off; } location /static/ { root /home/niscp/home-screen; } location /nicons/ { root /home/niscp/home-screen; } location / { include uwsgi_params; uwsgi_pass unix:/home/niscp/home-screen/home-screen.sock; } location /ws/ { proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_pass http://socket; } } Along with that, I am running individual instances of workers to listen to individual channels in the following manner: python manage.py runworker --only-channels=websocket.connect python manage.py runworker --only-channels=websocket.receive python manage.py runworker --only-channels=websocket.disconnect I have got uwsgi to handle all http requests the way django normally handles them. All daphne and workers do is handle WebSocket requests. Is this a viable method to scale django-channels, or is there something I could do better? -
