buildout环境中的Django独立脚本

时间：2012-03-22 12:29:06

标签： python django buildout

嗯这是一个相当苛刻的问题，“不同的解决方案提案”目前的情况不可用，所以请尽量帮我解决这个问题，不要避免它=）

所以有一个django项目使用buildout但不使用virtualenv（因为我们在安装字体时遇到问题......）。项目工作正常。现在我正在尝试实现django独立脚本，我认为我有一个路径问题。首先，我想介绍一个基础目录的结构。

roman% ls   
bootstrap.py    
cgi-bin

roman% tree parts

3 directories, 6 files

独立脚本位于/ srv / xxx / project / app / dir

现在最后是剧本：

import os
import sys 
import time
import pickle
from datetime import datetime
from pprint import pprint

sys.path.append(os.path.abspath('..'))
sys.path.append(os.path.abspath(os.path.join( '..', '..' ))) # Project dir
sys.path.append(os.path.abspath(os.path.join( '..', '..', 'parts', 'omelette')))
sys.path.append(os.path.abspath(os.path.join( '..', '..', 'eggs'))) 

from django.core.management import setup_environ
import settings                                                                                                                 

os.environ['DJANGO_SETTINGS_MODULE'] = 'settings.site_nl'

from django.template.loader import render_to_string

如果您运行此脚本，除最后一行外，一切正常。我甚至可以导入模型。无论如何，当我在ipython中执行它时，你可以通过自动完成导航到django.template，但更深层次的一切，例如django.template.loader / base / whatever - 不起作用..这个脚本的最后一行给出了这个错误< / p> 

roman% python email.py
Traceback (most recent call last):
  File "email.py", line 34, in <module>
    from django.template.loader import render_to_string

我想提一下，我试图从ports（包管理器）安装django，我检查了sys.path，是的，它是使用已安装的版本，仍然得到完全相同的错误。虽然django路径的一半是作品..

关于设置。我们为每个语言网站提供了5个设置文件。所以它是：settings.site_nl。如果我忘了添加内容，请在评论中留言。

基本上，如果你在脚本中手动处理sys.path，那么你使用buildout是错误的。 Buildout会为您处理所有已安装的蟒蛇蛋。如果django运行正常，你的脚本也应该。

您缺少的是一个可在bin目录中创建更多脚本的buildout部件。为此，在buildout中添加一个额外的部分（并将console_scripts添加到您的parts =列表中）：

[console_scripts]
recipe = zc.recipe.egg
interpreter = python
eggs =
    ${buildout:eggs}

运行buildout后，这会在bin/目录中为您提供大量额外脚本。其中bin/python。查看它，你会看到它包含正确的sys.path内容，由buildout预先配置。

（运行之后，您可能需要查看http://pypi.python.org/pypi/djangorecipe/1.1.2，这是一个扩展配方，使安装Django更加舒适）。

不要做愚蠢的事情，google为“django管理命令”
