Select between two dates with Django

I am looking to make a query that selects between dates with Django.

I know how to do this with raw SQL pretty easily, but how could this be achieved using the Django ORM?

This is where I want to add the between dates of 30 days in my query:

start_date = datetime.datetime.now() + datetime.timedelta(-30)
context[self.varname] = self.model._default_manager.filter(
    current_issue__isnull=True
    ).live().order_by("-created_at")

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.

I was preparing for my coding interview, thanks for clarifying this - Select between two dates with Django in Python is not the simplest one. Will use it in my bachelor thesis
