问题:

I looked at other questions and can't figure it out...

I did the following to install django-debug-toolbar:

  1. pip install django-debug-toolbar
  2. added to middleware classes:
MIDDLEWARE_CLASSES = (
    'django.middleware.common.CommonMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    # Uncomment the next line for simple clickjacking protection:
    # 'django.middleware.clickjacking.XFrameOptionsMiddleware',
    'debug_toolbar.middleware.DebugToolbarMiddleware',
)

3 Added INTERNAL_IPS:

INTERNAL_IPS = ('174.121.34.187',)

4 Added debug_toolbar to installed apps

I am not getting any errors or anything, and the toolbar doesn't show up on any page, not even admin.

I even added the directory of the debug_toolbar templates to my TEMPLATE_DIRS

回答1:

Stupid question, but you didn't mention it, so... What is DEBUG set to? It won't load unless it's True.

If it's still not working, try adding '127.0.0.1' to INTERNAL_IPS as well.

UPDATE

This is a last-ditch-effort move, you shouldn't have to do this, but it will clearly show if there's merely some configuration issue or whether there's some larger issue.

Add the following to settings.py:

def show_toolbar(request):
    return True
SHOW_TOOLBAR_CALLBACK = show_toolbar

That will effectively remove all checks by debug toolbar to determine if it should or should not load itself; it will always just load. Only leave that in for testing purposes, if you forget and launch with it, all your visitors will get to see your debug toolbar too.

For explicit configuration, also see the official install docs here.

EDIT(6/17/2015):

Apparently the syntax for the nuclear option has changed. It's now in its own dictionary:

def show_toolbar(request):
    return True
DEBUG_TOOLBAR_CONFIG = {
    "SHOW_TOOLBAR_CALLBACK" : show_toolbar,
}

Their tests use this dictionary.



回答2:

Debug toolbar wants the ip address in request.META['REMOTE_ADDR'] to be set in the INTERNAL_IPS setting. Throw in a print statement in one of your views like such:

print("IP Address for debug-toolbar: " + request.META['REMOTE_ADDR'])

And then load that page. Make sure that IP is in your INTERNAL_IPS setting in settings.py.

Normally I'd think you would be able to determine the address easily by looking at your computer's ip address, but in my case I'm running the server in a Virtual Box with port forwarding...and who knows what happened. Despite not seeing it anywhere in ifconfig on the VB or my own OS, the IP that showed up in the REMOTE_ADDR key was what did the trick of activating the toolbar.



回答3:

If everything else is fine, it could also be that your template lacks an explicit closing <body> tag—

Note: The debug toolbar will only display itself if the mimetype of the response is either text/html or application/xhtml+xml and contains a closing tag.



回答4:

The current stable version 0.11.0 requires the following things to be true for the toolbar to be shown:

Settings file:

  1. DEBUG = True
  2. INTERNAL_IPS to include your browser IP address, as opposed to the server address. If browsing locally this should be INTERNAL_IPS = ('127.0.0.1',). If browsing remotely just specify your public address.
  3. The debug_toolbar app to be installed i.e INSTALLED_APPS = (..., 'debug_toolbar',)
  4. The debug toolbar middleware class to be added i.e. MIDDLEWARE_CLASSES = ('debug_toolbar.middleware.DebugToolbarMiddleware', ...). It should be placed as early as possible in the list.

Template files:

  1. Must be of type text/html
  2. Must have a closing </html> tag

Static files:

If you are serving static content make sure you collect the css, js and html by doing: 

./manage.py collectstatic

Note on upcoming versions of django-debug-toolbar

Newer, development versions have added defaults for settings points 2, 3 and 4 which makes life a bit simpler, however, as with any development version it has bugs. I found that the latest version from git resulted in an ImproperlyConfigured error when running through nginx/uwsgi.

Either way, if you want to install the latest version from github run:

pip install -e git+https://github.com/django-debug-toolbar/django-debug-toolbar.git#egg=django-debug-toolbar

You can also clone a specific commit by doing: 

pip install -e git+https://github.com/django-debug-toolbar/django-debug-toolbar.git@ba5af8f6fe7836eef0a0c85dd1e6d7418bc87f75#egg=django_debug_toolbar


回答5:

I have the toolbar working just perfect. With this configurations:

  1. DEBUG = True
  2. INTERNAL_IPS = ('127.0.0.1', '192.168.0.1',)
  3. DEBUG_TOOLBAR_CONFIG = {'INTERCEPT_REDIRECTS': False,}
  4. The middleware is the first element in MIDDLEWARE_CLASSES:
MIDDLEWARE_CLASSES = (
    'debug_toolbar.middleware.DebugToolbarMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
)

I hope it helps



回答6:

I tried everything, from setting DEBUG = True, to settings INTERNAL_IPS to my client's IP address, and even configuring Django Debug Toolbar manually (note that recent versions make all configurations automatically, such as adding the middleware and URLs). Nothing worked in a remote development server (though it did work locally). The ONLY thing that worked was configuring the toolbar as follows:

DEBUG_TOOLBAR_CONFIG = {
    "SHOW_TOOLBAR_CALLBACK" : lambda request: True,
}

This replaces the default method that decides if the toolbar should be shown, and always returns true.



回答7:

Add 10.0.2.2 to your INTERNAL_IPS on Windows, it is used with vagrant internally

INTERNAL_IPS = ( '10.0.2.2', )

This should work.



回答8:

I had the same problem and finally resolved it after some googling.

In INTERNAL_IPS, you need to have the client's IP address.



回答9:

Another thing that can cause the toolbar to remain hidden is if it cannot find the required static files. The debug_toolbar templates use the {{ STATIC_URL }} template tag, so make sure there is a folder in your static files called debug toolbar.

The collectstatic management command should take care of this on most installations.



回答10:

I tried the configuration from pydanny's cookiecutter-django and it worked for me:

# django-debug-toolbar
MIDDLEWARE_CLASSES = Common.MIDDLEWARE_CLASSES + ('debug_toolbar.middleware.DebugToolbarMiddleware',)
INSTALLED_APPS += ('debug_toolbar',)

INTERNAL_IPS = ('127.0.0.1',)

DEBUG_TOOLBAR_CONFIG = {
    'DISABLE_PANELS': [
        'debug_toolbar.panels.redirects.RedirectsPanel',
    ],
    'SHOW_TEMPLATE_CONTEXT': True,
}
# end django-debug-toolbar

I just modified it by adding 'debug_toolbar.apps.DebugToolbarConfig' instead of 'debug_toolbar' as mentioned in the official django-debug-toolbar docs, as I'm using Django 1.7.



回答11:

An addition to previous answers:

if the toolbar doesn't show up, but it loads in the html (check your site html in a browser, scroll down)

the issue can be that debug toolbar static files are not found (you can also see this in your site's access logs then, e.g. 404 errors for /static/debug_toolbar/js/toolbar.js)

It can be fixed the following way then (examples for nginx and apache):

nginx config:

location ~* ^/static/debug_toolbar/.+.(ico|css|js)$ {
    root [path to your python site-packages here]/site-packages/debug_toolbar;
}

apache config:

Alias /static/debug_toolbar [path to your python site-packages here]/site-packages/debug_toolbar/static/debug_toolbar

Or:

manage.py collectstatic

more on collectstatic here: https://docs.djangoproject.com/en/dev/ref/contrib/staticfiles/#collectstatic

Or manualy move debug_toolbar folder of debug_toolbar static files to your set static files folder



回答12:

django 1.8.5:

I had to add the following to the project url.py file to get the debug toolbar display. After that debug tool bar is displayed.

 from django.conf.urls import include
 from django.conf.urls import patterns
 from django.conf import settings


  if settings.DEBUG:
      import debug_toolbar
      urlpatterns += patterns('',
              url(r'^__debug__/', include(debug_toolbar.urls)),
              )

django 1.10: and higher:

from django.conf.urls import include, url
from django.conf.urls import patterns
from django.conf import settings


if settings.DEBUG:

  import debug_toolbar
  urlpatterns =[
         url(r'^__debug__/', include(debug_toolbar.urls)),
         ] + urlpatterns

Also don't forget to include the debug_toolbar to your middleware. The Debug Toolbar is mostly implemented in a middleware. Enable it in your settings module as follows: (django newer versions)

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

Old-style middleware:(need to have _CLASSES keywork in the Middleware)

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

Docker

If you're developing with a Django server in a Docker container with docker, the instructions for enabling the toolbar don't work. The reason is related to the fact that the actual address that you would need to add to INTERNAL_IPS is going to be something dynamic, like 172.24.0.1. Rather than trying to dynamically set the value of INTERNAL_IPS, the straightforward solution is to replace the function that enables the toolbar, in your settings.py, for example:

DEBUG_TOOLBAR_CONFIG = {
    'SHOW_TOOLBAR_CALLBACK': lambda _request: DEBUG
}


This should also work for other dynamic routing situations, like vagrant.

Here are some more details for the curious. The code in django_debug_tool that determines whether to show the toolbar examines the value of REMOTE_ADDR like this:

if request.META.get('REMOTE_ADDR', None) not in INTERNAL_IPS:
       return False

so if you don't actually know the value of REMOTE_ADDR due to your dynamic docker routing, the toolbar will not work. You can use the docker network command to see the dynamic IP values, for example docker network inspect my_docker_network_name



回答14:

This wasn't the case for this specific author but I just have been struggling with the Debug Toolbar not showing and after doing everything they pointed out, I found out it was a problem with MIDDLEWARE order. So putting the middleware early in the list could work. Mine is first:

MIDDLEWARE_CLASSES = ( 'debug_toolbar.middleware.DebugToolbarMiddleware', 'django.middleware.common.CommonMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'dynpages.middleware.DynpageFallbackMiddleware', 'utils.middleware.UserThread', )



回答15:

In my case, it was another problem that hasn't been mentioned here yet: I had GZipMiddleware in my list of middlewares.

As the automatic configuration of debug toolbar puts the debug toolbar's middleware at the top, it only gets the "see" the gzipped HTML, to which it can't add the toolbar.

I removed GZipMiddleware in my development settings. Setting up the debug toolbar's configuration manually and placing the middleware after GZip's should also work.



回答16:

In my case I just needed to remove the python compiled files (*.pyc)



回答17:

you have to make sure there is a closing tag in your templates.

My problem is that there is no regular html tags in my templates, I just display content in plain text. I solved it by inheriting every html file from base.html, which has a tag.



回答18:

For me this was as simple as typing 127.0.0.1:8000 into the address bar, rather than localhost:8000 which apparently was not matching the INTERNAL_IPS.



回答19:

I got the same problem, I solved it by looking at the Apache's error log. I got the apache running on mac os x with mod_wsgi The debug_toolbar's tamplete folder wasn't being load

Log sample:

==> /private/var/log/apache2/dummy-host2.example.com-error_log <==
[Sun Apr 27 23:23:48 2014] [error] [client 127.0.0.1] File does not exist: /Library/WebServer/Documents/rblreport/rbl/static/debug_toolbar, referer: http://127.0.0.1/

==> /private/var/log/apache2/dummy-host2.example.com-access_log <==
127.0.0.1 - - [27/Apr/2014:23:23:48 -0300] "GET /static/debug_toolbar/css/toolbar.css HTTP/1.1" 404 234 "http://127.0.0.1/" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:28.0) Gecko/20100101 Firefox/28.0"

I just add this line to my VirtualHost file:

Alias /static/debug_toolbar /Library/Python/2.7/site-packages/debug_toolbar/static/debug_toolbar
  • Of course you must change your python path


回答20:

I had the same problem using Vagrant. I solved this problem by adding ::ffff:192.168.33.1 to the INTERNAL_IPS as below example. 

INTERNAL_IPS = (
    '::ffff:192.168.33.1',
)

Remembering that 192.168.33.10 is the IP in my private network in Vagrantfile.



回答21:

I had this problem and had to install the debug toolbar from source.

Version 1.4 has a problem where it's hidden if you use PureCSS and apparently other CSS frameworks.

This is the commit which fixes that.

The docs explain how to install from source.



回答22:

For anyone who is using Pycharm 5 - template debug is not working there in some versions. Fixed in 5.0.4, affected vesions - 5.0.1, 5.0.2 Check out issue

Spend A LOT time to find that out. Maybe will help someone



回答23:

In the code I was working on, multiple small requests were made during handling of main request (it's very specific use case). They were requests handled by the same Django's thread. Django debug toolbar (DjDT) doesn't expect this behaviour and includes DjDT's toolbars to the first response and then it removes its state for the thread. So when main request was sent back to the browser, DjDT was not included in the response.

Lessons learned: DjDT saves it's state per thread. It removes state for a thread after the first response.



回答24:

One stupid thing got me.. that if you use apache wsgi, remember to touch the .wsgi file to force your code recompile. just waste 20 minutes of my time to debug the stupid error :(
