我已经把django-pdb推到了PyPI。 这是一个简单的应用程序，这意味着你不需要编辑你的源代码，每次你想进入pdb。

安装只是…

PIP安装django-pdb 添加'django_pdb'到你的INSTALLED_APPS

你现在可以运行:manage.py runserver——pdb在每个视图的开始进入pdb…

bash: manage.py runserver --pdb
Validating models...

0 errors found
Django version 1.3, using settings 'testproject.settings'
Development server is running at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

GET /
function "myview" in testapp/views.py:6
args: ()
kwargs: {}

> /Users/tom/github/django-pdb/testproject/testapp/views.py(7)myview()
-> a = 1
(Pdb)

然后运行:manage.py test——pdb在测试失败/错误时进入pdb…

bash: manage.py test testapp --pdb
Creating test database for alias 'default'...

> /Users/tom/github/django-pdb/testproject/testapp/tests.py(16)test_error()

该项目托管在GitHub上，当然欢迎贡献。

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!：）

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

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

参见:https://poweruser.blog/setting-a-breakpoint-in-python-438e23fe6b28

从我的角度来看，我们可以将常见的代码调试任务分解为三种不同的使用模式:

Something has raised an exception: runserver_plus' Werkzeug debugger to the rescue. The ability to run custom code at all the trace levels is a killer. And if you're completely stuck, you can create a Gist to share with just a click. Page is rendered, but the result is wrong: again, Werkzeug rocks. To make a breakpoint in code, just type assert False in the place you want to stop at. Code works wrong, but the quick look doesn't help. Most probably, an algorithmic problem. Sigh. Then I usually fire up a console debugger PuDB: import pudb; pudb.set_trace(). The main advantage over [i]pdb is that PuDB (while looking as you're in 80's) makes setting custom watch expressions a breeze. And debugging a bunch of nested loops is much simpler with a GUI.

啊，是的，模板的问题。最常见的问题(对我和我的同事来说)是错误的上下文:要么你没有变量，要么你的变量没有某些属性。如果你正在使用调试工具栏，只检查“模板”部分的上下文，或者，如果这还不够，在你的上下文填充后，在视图的代码中设置一个断点。

就这样。

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
