我正在尝试将django-debug-toolbar与我的django应用程序一起使用,它适用于django v1.5。但是,我正在尝试将系统迁移到django v1.6,当我尝试加载任何页面时,它会生成以下错误。
python manage.py runserver

Django version 1.6.1, using settings 'MySite.settings'

Quit the server with CONTROL-C.

来源有这个说明,但我不确定它们的含义是什么(import_by_path):
def process_request(self, request):
# Decide whether the toolbar is active for this request.
func_path = dt_settings.CONFIG['SHOW_TOOLBAR_CALLBACK']
# Replace this with import_by_path in Django >= 1.6.
mod_path, func_name = func_path.rsplit('.', 1)
show_toolbar = getattr(import_module(mod_path), func_name)
if not show_toolbar(request):
return
此外,我们正在努力。知道这个消息的意思吗?
/home/user/django-env/local/lib/python2.7/site-packages/debug_toolbar/settings.py:68: DeprecationWarning: SHOW_TOOLBAR_CALLBACK is now a dotted path. Update your DEBUG_TOOLBAR_CONFIG setting.
"DEBUG_TOOLBAR_CONFIG setting.", DeprecationWarning)
我的settings.py:
def custom_show_toolbar(request):
return True # Always show toolbar, for example purposes only.
DEBUG_TOOLBAR_CONFIG = {
'INTERCEPT_REDIRECTS': False,
'SHOW_TOOLBAR_CALLBACK': custom_show_toolbar,
'INSERT_BEFORE': 'div',
'ENABLE_STACKTRACES' : True,
}
答案 0 :(得分:22)
问题由您收到的消息描述(不应该是弃用警告,而应该是TypeError
,这可能是debug_toolbar
中的错误):
SHOW_TOOLBAR_CALLBACK现在是一个虚线路径。更新您的DEBUG_TOOLBAR_CONFIG设置
SHOW_TOOLBAR_CALLBACK
设置曾经是可调用的,但现在it is a dotted path是可调用的:字符串。您引用的代码会尝试rsplit
SHOW_TOOLBAR_CALLBACK
的值,但由于您无法rsplit
函数对象,因此会出现错误。
要解决此问题,请将回调放入另一个python文件,例如your_site/toolbar_stuff.py
,并将设置调整为'SHOW_TOOLBAR_CALLBACK': 'your_site.toolbar_stuff.custom_show_toolbar'
。你可以通过尝试shell来测试它是否有效:
from your_site.toolbar_stuff import custom_show_toolbar
如果有效,您的新设置也应该有效。
