从命令行通过 shell_plus 运行 python 脚本

Question

我有一个 python 脚本，我运行它来填充我的数据库。 由于需要依赖，我通常在 shell_plus 中运行脚本。 有没有办法将脚本加载到 shell_plus 并从我的 linux 命令行运行所有内容，而无需实际打开 shell_plus 界面？

Answer 1

“独立的 Django 脚本”

Answer 2

你打赌！

我什至不推荐使用 shell_plus。 我倾向于将我的实用程序脚本存储在我的应用程序实用程序文件夹中。 然后我只需从 cron 作业或根据需要手动调用它们。 这是我以此为基础的框架脚本。 （有些简化）

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import os
import sys
import logging
import time
import time
import optparse

# DO NOT IMPORT DJANGO MODELS HERE - THIS NEED TO HAPPEN BELOW!!
# This needs to be able to be run when django isn't in the picture (cron) so we need
# to be able to add in the django paths when needed.

def getArgs():
    """
        Simply get the options for running update people.
    """

    p = optparse.OptionParser()

    help = "The Python path to a settings module, e.g. "
    help += "\"myproject.settings.main\". If this isn't provided, the "
    help += "DJANGO_SETTINGS_MODULE environment variable will be used."
    p.add_option("-s", "--settings", action = "store", type = "string",
                 dest = "settings", help = help)

    help = "A directory to add to the Python path, e.g."
    help += " \"/home/djangoprojects/myproject\"."
    p.add_option("-y", "--pythonpath", action = "store", type = "string",
                 dest = "pythonpath", help = help)
    p.add_option("-v", "--verbose", action = "count", dest = "verbose",
                 help = "Turn on verbose debugging")
    p.set_defaults(settings = os.environ.get("DJANGO_SETTINGS_MODULE",
                                              "settings"),
                   pythonpath = "", verbose = 0,
                   )

    return p.parse_args()


def update(opt, loglevel=None):

    start = time.time()

    # This ensures that our sys.path is ready.
    for path in opt.pythonpath.split(":"):
        if os.path.abspath(path) not in sys.path and os.path.isdir(path):
            sys.path.append(os.path.abspath(path))

    from django.conf import settings    
    try:

    except ImportError:
        return("Your setting file cannot be imported - not in sys.path??")

    # IMPORT YOUR CODE MODELS HERE
    from apps.core.utility.ExampleExtractor import ExampleExtractor

    # YOUR DJANGO STUFF GOES HERE..
    example = ExampleExtractor(loglevel=loglevel, singleton=not(opt.multiple))
    raw = example.get_raw()
    results = example.update_django(raw)

    log.info("Time to update %s entries : %s" % (len(results), time.time() - start))
    return results


if __name__ == '__main__':

    logging.basicConfig(format = "%(asctime)s %(levelname)-8s %(module)s \

HTH！
