Hello, I am developing a system to learn python(django), but I am stuck in an error, which unfortunately is simple when I google search, no result was similar to my case ... In my system, first registration is from Clients, later Hosts. I created the CRUD Client that worked as expected, but when creating the CRUD Host, I added a Select element that lists the Clients, to add a Host, the template passed the Select data via Post normally. But on the Update template, it simply does not pass Select value via post to the view ... <select type="id_client" name="id_client"> <option value="{{ h.id_client }}" selected>{{ h.id_client.name }}</option> {% for c in clients %} <option value="{{ c.id_client }}">{{ c.name }}</option> {% endfor %} </select> For a Select that does not change in an update view, is it necessary to do something different?

Debugging, I found that in the view the field is receive the value: "---------"

I use postgres in chat app for storing messages. I work with web sockets (channels). Is it not expensive to make query to db and save message every time when a user send message?

Postgres is pretty performant. Will your chat app ever need to exceed thousands of INSERTs per second? Do you have that many active concurrent users?
