Let"s say that we have the following model:
class Classroom(models.Model):
room_number = [...]
class Teacher(models.Model):
name = [...]
tenure = [...]
classroom = models.ForeignKey(Classroom)
Let"s say that instead of getting a result like this per the ManyRelatedPrimaryKeyField function:
{
"room_number": "42",
"teachers": [
27,
24,
7
]
},
have it return something that includes the full related model representation like:
{
"room_number": "42",
"teachers": [
{
"id": 27,
"name": "John",
"tenure": True
},
{
"id": 24,
"name": "Sally",
"tenure": False
},
]
},
Is this possible? If so, how? And is this a bad 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
