How come my "date" field doesn"t come up in the admin system?
In my admin.py file i have
from django.contrib import admin
from glasses.players.models import *
admin.site.register(Rating)
and the Rating model has a field called "date" which looks like this
date = models.DateTimeField(editable=True, auto_now_add=True)
However within the admin system, the field doesn"t show, even though editable
is set to True
.
Does anyone have any idea?

How can I make a time delay in Python?
5 answers
I would like to know how to put a time delay in a Python script.
Answer #1
import time
time.sleep(5) # Delays for 5 seconds. You can also use a float value.
Here is another example where something is run approximately once a minute:
import time
while True:
print("This prints once a minute.")
time.sleep(60) # Delay for 1 minute (60 seconds).
Answer #2
You can use the sleep()
function in the time
module. It can take a float argument for sub-second resolution.
from time import sleep
sleep(0.1) # Time in seconds

I was preparing for my coding interview, thanks for clarifying this - DateTimeField doesn”t show in admin system in Python is not the simplest one. Will use it in my bachelor thesis
