I"m working on a project in Django and I"ve just started trying to extend the User model in order to make user profiles.

Unfortunately, I"ve run into a problem: Every time I try to get the user"s profile inside of a template (user.get_template.lastIP, for example), I get the following error:

Environment:

Request Method: GET
Request URL: http://localhost:8000/
Django Version: 1.1
Python Version: 2.6.1

Template error:
In template /path/to/base.tpl, error at line 19
   Caught an exception while rendering: too many values to unpack

19 :                Hello, {{user.username}} ({{ user.get_profile.rep}}). How"s it goin? Logout


Exception Type: TemplateSyntaxError at /
Exception Value: Caught an exception while rendering: too many values to unpack

Any ideas as to what"s going on or what I"m doing wrong?

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

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.
