Django: Why do some model fields clash with each other?

👻 Check our latest review to choose the best laptop for Machine Learning engineers and Deep learning tasks!

I want to create an object that contains 2 links to Users. For example:

class GameClaim(models.Model):
    target = models.ForeignKey(User)
    claimer = models.ForeignKey(User)
    isAccepted = models.BooleanField()

but I am getting the following errors when running the server:

Accessor for field "target" clashes with related field "User.gameclaim_set". Add a related_name argument to the definition for "target".
Accessor for field "claimer" clashes with related field "User.gameclaim_set". Add a related_name argument to the definition for "claimer".

Can you please explain why I am getting the errors and how to fix them?

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

How do I delete a file or folder in Python?

Answer #1

os.remove() removes a file.
os.rmdir() removes an empty directory.
shutil.rmtree() deletes a directory and all its contents.

Path objects from the Python 3.4+ pathlib module also expose these instance methods:

pathlib.Path.unlink() removes a file or symbolic link.
pathlib.Path.rmdir() removes an empty directory.
