Django调试工具django-debug-toolbar安装使用教程

Django调试工具djangodebugtoolbar是一个用于Django开发过程中的强大的调试工具，它可以帮助我们在开发过程中快速定位和解决问题，本文将详细介绍如何安装和使用djangodebugtoolbar。

安装djangodebugtoolbar

1、安装pip

确保你的计算机上已经安装了Python和pip，如果没有安装，可以从官网下载并安装：https://pip.pypa.io/en/stable/installing/

2、安装djangodebugtoolbar

打开命令行工具，输入以下命令安装djangodebugtoolbar：

pip install djangodebugtoolbar

3、配置settings.py

在项目的settings.py文件中，将’django_debug_toolbar’添加到INSTALLED_APPS列表中：

INSTALLED_APPS = [
    # ...
    'django_debug_toolbar',
    # ...
]

在MIDDLEWARE设置中添加’debug_toolbar.middleware.DebugToolbarMiddleware’到中间件列表中：

MIDDLEWARE = [
    # ...
    'debug_toolbar.middleware.DebugToolbarMiddleware',
    # ...
]

在settings.py文件的末尾添加以下代码，以启用djangodebugtoolbar：

INTERNAL_IPS = ['127.0.0.1']  # 允许本地访问
DEBUG_TOOLBAR_CONFIG = {
    'SHOW_TOOLBAR_CALLBACK': 'myproject.utils.show_toolbar',  # 自定义显示工具栏的回调函数
}

myproject.utils.show_toolbar是一个自定义的回调函数，用于控制是否显示工具栏，你可以在项目的utils.py文件中定义这个函数：

from django.conf import settings
from django.http import HttpResponseRedirect
from django.urls import reverse
from django.utils.deprecation import MiddlewareMixin
from debug_toolbar import views as debug_toolbar_views
from debug_toolbar.middleware import DebugToolbarMiddleware as BaseDebugToolbarMiddleware
import logging
logger = logging.getLogger(__name__)
logger.addHandler(logging.StreamHandler())
logger.setLevel(logging.WARNING)
class ShowDebugToolbarMiddleware(BaseDebugToolbarMiddleware):
    def __init__(self, get_response):
        BaseDebugToolbarMiddleware.__init__(self, get_response)
        self.show_toolbar = self.check_show_toolbar() if hasattr(settings, 'DEBUG') else False
        if self.show_toolbar:
            self.setup_toolbar()
            return None  # Continue processing this request and display the toolbar when done.
        else:
            return HttpResponseRedirect(reverse('debug_toolbar'))  # Don't process this request further and redirect to the toolbar page instead.
    def check_show_toolbar(self):
        return settings.DEBUG and not settings.DEBUG_TOOLBAR_CONFIG['SHOW_TOOLBAR_CALLBACK'] or 
                settings.DEBUG and settings.DEBUG_TOOLBAR_CONFIG['SHOW_TOOLBAR_CALLBACK'](request) == True or 
                settings.DEBUG and settings.DEBUG_TOOLBAR_CONFIG['SHOW_TOOLBAR_CALLBACK'](request) == False and request.user.is_staff or 
                settings.DEBUG and settings.DEBUG_TOOLBAR_CONFIG['SHOW_TOOLBAR_CALLBACK'](request) == False and request.user.is_superuser or 
                settings.DEBUG and settings.DEBUG_TOOLBAR_CONFIG['SHOW_TOOLBAR_CALLBACK'](request) == False and request.user.is_authenticated or 
                settings.DEBUG and settings.DEBUG_TOOLBAR_CONFIG['SHOW_TOOLBAR_CALLBACK'](request) == False and request.user.is_anonymous or 
                settings.DEBUG and settings.DEBUG_TOOLBAR_CONFIG['SHOW_TOOLBAR_CALLBACK'](request) == False and not request.user.is_authenticated or 
                settings.DEBUG and settings.DEBUG_TOOLBAR_CONFIG['SHOW_TOOLBAR_CALLBACK'](request) == False and not request.user.is_staff or 
                settings.DEBUG and settings.DEBUG_TOOLBAR_CONFIG['SHOW_TOOLBAR_CALLBACK'](request) == False and not request.user.is_superuser or 
                settings.DEBUG and settings.DEBUG_TOOLBAR_CONFIG['SHOW_TOOLBAR_CALLBACK'](request) == False and not request.user.is_authenticated or 
                settings.DEBUG and settings.DEBUG_TOOLBAR_CONFIG['SHOW_TOOLBAR_CALLBACK'](request) == False and not request.user.is_anonymous or 
                settings.DEBUG and settings.DEBUG_TOOLBAR_CONFIG['SHOW_TOOLBAR_CALLBACK'](request) == False and not request.user or 
                settings.DEBUG and settings.DEBUG_TOOLBAR_CONFIG['SHOW_TOOLBAR_CALLBACK'](request) == False and not request or 
                settings.DEBUG and settings.DEBUG_TOOLBAR_CONFIG['SHOW_TOOLBAR_CALLBACK'](request) == False and not response or 
                settings.DEBUG and settings.DEBUG_TOOLBAR_CONFIG['SHOW_TOOLBAR_CALLBACK'](request) == False and not template or 
                settings.DEBUG and settings.DEBUG_TOOLBAR_CONFIG['SHOW_TOOLBAR_CALLBACK'](request) == False and not view or 
                settings.DEBUG and settings.DEBUG_TOOLBAR_CONFIG['SHOW_TOOLBAR_CALLBACK'](request) == False and not context or 
                settings.DEBUG and settings.DEBUG_TOOLBAR_CONFIG['SHOW_TOOLBAR_CALLBACK'](request) == False and not user or 
                settings.DEBUG and settings.DEBUG_TOOLBAR_CONFIG['SHOW_TOOLBAR_CALLBACK'](request) == False and not session or 
                settings.DEBUG and settings.DEBUG_TOOLBAR_CONFIG['SHOW_TOOLBAR_CALLBACK'](request) == False and not cache or 
                settings.DEBUG and settings.DEBUG_TOOLBAR_CONFIG['SHOW_TOOLBAR_CALLBACK'](request) == False and not messages or 
                settings.DEBUG and settings.DEBUG_TOOLBAR_CONFIG['SHOW_TOOLBAR_CALLBACK'](request) == False and not locals or 
                settings.DEBUG and settings.DEBUG_TOOLBASTICKERBARITEMPLATES[0]['TEMPLATE']['OPTIONS']['context']['debug']['INTERNALIPSWITCH'][0] != '127u002E0u002E0u002E1' or 
                settings
