获取Django项目使用的python包的列表 [英] Get a list of python packages used by a Django Project

问题描述

我有看过snakefood和这个问题，但在django环境中似乎都没有很好地发挥。

理想情况下，我正在寻找一个可以从python shell或bash中执行的命令，列出所有不支持django本机的pypy支持的依赖项。

解决方案

这不是一个完整的答案，但希望它会成为一个明智的起点。

从我可以看出，django项目的依赖关系（除了django本身及其依赖项 * ）包括：

1. 您的django项目导入的模块


2. 您的项目通过 settings.INSTALLED_APPS （及其依赖项）

＃1项目导入的模块

您可以使用 snakefood 发现这一点。 p>

＃2通过 settings.INSTALLED_APPS加载的应用程序

运行以下脚本应该给出 INSTALLED_APPS 中列出的应用程序的路径：

  ＃！/ usr / bin / env python 
从设置导入INSTALLED_APPS 
从django.utils.importlib import import_module 
 import os 
 
 app_names =（x for x in INSTALLED_APPS如果不是x.startswith（'django'））
 app_paths =（os.path.dirname（os.path .abspath（import_module（x）.__ file__））for x in app_names 
 print\\\
.join（x for app in app_paths if not x.startswith（os.getcwd（）））
  

然后，您可以将其传递给 snakefood 以发现他们依赖关系。

* 要彻底，应该可以从设置中发现各种后端（db / cache / auth / etc），并将相关模块包含在您的依赖关系列表中。

Is there any easy way to get a list of python packages used by a Django project?

I've looked at snakefood and this question, but neither seem to play nicely within the django environment.

Ideally I'm looking for a command I can execute from the python shell or from bash to list all of the pypy supported dependencies that aren't native to django.

解决方案

This isn't a complete answer but hopefully it'll make a sensible starting point.

From what I can tell, the dependencies of a django project (apart from django itself and its dependencies*) consists of:

1. Modules imported by your django project
2. Apps loaded by your project via settings.INSTALLED_APPS (and their dependencies)

#1 Modules imported by your project

You can probably discover this using snakefood.

#2 Apps loaded via settings.INSTALLED_APPS

Running the following script should give the path to apps listed in INSTALLED_APPS:

#!/usr/bin/env python
from settings import INSTALLED_APPS
from django.utils.importlib import import_module
import os

app_names = (x for x in INSTALLED_APPS if not x.startswith('django'))
app_paths = (os.path.dirname(os.path.abspath(import_module(x).__file__)) for x in app_names)    
print "\n".join(x for x in app_paths if not x.startswith(os.getcwd()))

You can then pass this on to snakefood to discover their dependencies.

* To be thorough, it should be possible to discover the various backends (db/cache/auth/etc.) from settings and include the associated modules into your list of dependencies.
