如何在Django中调试，好方法?

So, I started learning to code in Python and later Django. The first times it was hard looking at tracebacks and actually figure out what I did wrong and where the syntax error was. Some time has passed now and some way along the way, I guess I got a routine in debugging my Django code. As this was done early in my coding experience, I sat down and wondered if how I was doing this was ineffective and could be done faster. I usually manage to find and correct the bugs in my code, but I wonder if I should be doing it faster?

我通常只使用Django启用时提供的调试信息。当事情确实像我想象的那样结束时，我用一个语法错误破坏了代码流，并查看流中那个点的变量，以找出代码在哪里做了与我想要的不同的事情。

但这种情况还能改善吗?是否有一些更好的工具或方法来调试Django代码?

使用PDB或ipdb。这两者的区别是ipdb支持自动完成。

pdb的

import pdb
pdb.set_trace()

对于ipdb

import ipdb
ipdb.set_trace()

执行换行按n键，继续按c键。使用帮助(pdb)检查更多选项

调试Django代码的最佳选择之一是通过wdb: https://github.com/Kozea/wdb

wdb works with python 2 (2.6, 2.7), python 3 (3.2, 3.3, 3.4, 3.5) and pypy. Even better, it is possible to debug a python 2 program with a wdb server running on python 3 and vice-versa or debug a program running on a computer with a debugging server running on another computer inside a web page on a third computer! Even betterer, it is now possible to pause a currently running python process/thread using code injection from the web interface. (This requires gdb and ptrace enabled) In other words it's a very enhanced version of pdb directly in your browser with nice features.

安装并运行服务器，并在代码中添加:

import wdb
wdb.set_trace()

作者认为，pdb的主要区别是:

For those who don’t know the project, wdb is a python debugger like pdb, but with a slick web front-end and a lot of additional features, such as: Source syntax highlighting Visual breakpoints Interactive code completion using jedi Persistent breakpoints Deep objects inspection using mouse Multithreading / Multiprocessing support Remote debugging Watch expressions In debugger code edition Popular web servers integration to break on error In exception breaking during trace (not post-mortem) in contrary to the werkzeug debugger for instance Breaking in currently running programs through code injection (on supported systems)

它有一个很棒的基于浏览器的用户界面。一种使用的乐趣!：）

添加导入pdb;pdb.set_trace()或breakpoint()(形式python3.7)在Python代码中的相应行中执行。执行将在交互式shell中停止。在shell中，您可以执行Python代码(即打印变量)或使用如下命令:

C继续执行 N步到同一函数中的下一行 S步到这个函数或被调用函数的下一行 Q退出调试器/执行

如果在django开发中使用Aptana，请注意:http://www.youtube.com/watch?v=qQh-UQFltJQ

如果没有，考虑使用它。

对于那些不小心将pdb添加到实时提交的人，我可以建议这个扩展#Koobz的答案:

@register.filter 
def pdb(element):
    from django.conf import settings
    if settings.DEBUG:    
        import pdb
        pdb.set_trace()
    return element

我使用PyCharm和其他调试工具。还有一篇不错的文章介绍如何为新手设置这些东西。你可以从这里开始。它讲述了Django项目的PDB和GUI调试。希望有人能从中受益。
