從命令行通過shell_plus運行python腳本

Question

我有一個python腳本來運行我的數據庫。由於需要依賴關係，我通常在shell_plus內運行腳本。有沒有辦法將腳本加載到shell_plus中，然後在沒有實際打開shell_plus接口的情況下運行我的linux命令行中的所有內容？

Answer 1

"Standalone Django scripts"

Answer 2

你打賭！

我甚至不推薦使用shell_plus。我傾向於將我的實用程序腳本存儲在我的應用實用程序文件夾中然後，我只需從cron作業調用它們或根據需要手動調用它們。這裏是框架腳本我基於此。 （有點簡化）

#!/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)) 
    os.environ['DJANGO_SETTINGS_MODULE'] = opt.settings 

    from django.conf import settings  
    try: 
     if settings.SITE_ROOT not in sys.path: pass 
    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 \

    log = logging.getLogger("") 
    log.setLevel(logging.DEBUG) 

    opts, args = getArgs() 
    sys.exit(update(opts)) 

HTH！
