如何使用django-debug-toolbar for django-tastypie？
django-debug-工具栏需要它的输出是html，但是django-tastypie的默认输出格式是json。
我试着发送http://localhost/api/v1/resource/?format=html，但显示为Sorry, not implemented yet. Please append "?format=json" to your URL
尽管这个文档列出了html作为有效选项之一，但它说它在TODO list上。
http://django-tastypie.readthedocs.org/en/latest/serialization.html#to-html
如何使用调试工具栏调试tastypie调用？
(例如，我想看看有多少sql查询正在为api调用运行。以此类推)
也许我可以从django视图调用api，但是如何调用呢？

下面是我为类似目的编写的一个中间件，它将json包装在HTML中，以启用调试工具栏，并打印出来。此外，它还支持二进制数据。我没有使用tastypie，但我认为它也应该与它一起工作。
# settings-dev.py
from django.http import HttpResponse
import json
MIDDLEWARE_CLASSES += (
'debug_toolbar.middleware.DebugToolbarMiddleware',
'NonHtmlDebugToolbarMiddleware',
)
class NonHtmlDebugToolbarMiddleware(object):
"""
The Django Debug Toolbar usually only works for views that return HTML.
This middleware wraps any non-HTML response in HTML if the request
has a 'debug' query parameter (e.g. http://localhost/foo?debug)
Special handling for json (pretty printing) and
binary data (only show data length)
"""
@staticmethod
def process_response(request, response):
if request.GET.get('debug') == '':
if response['Content-Type'] == 'application/octet-stream':
new_content = '<html><body>Binary Data, ' \
'Length: {}</body></html>'.format(len(response.content))
response = HttpResponse(new_content)
elif response['Content-Type'] != 'text/html':
content = response.content
try:
json_ = json.loads(content)
content = json.dumps(json_, sort_keys=True, indent=2)
except ValueError:
pass
response = HttpResponse('<html><body><pre>{}'
'</pre></body></html>'.format(content))

Django Debug Toolbar的中间件实际上包含代码，以防止它被激活用于非html类型的响应，如TastyPie返回的响应。我在过去所做的是创建一些中间件来将json响应转换成HTML，这样工具栏就会被激活，我可以计算查询等。这是一个小技巧，但它可以完成工作，并且很容易打开/关闭。
from django.conf import settings
class JsonAsHTML(object):
'''
View a JSON response in your browser as HTML
Useful for viewing stats using Django Debug Toolbar
This middleware should be place AFTER Django Debug Toolbar middleware
'''
def process_response(self, request, response):
#not for production or production like environment
if not settings.DEBUG:
return response
#do nothing for actual ajax requests
if request.is_ajax():
return response
#only do something if this is a json response
if "application/json" in response['Content-Type'].lower():
title = "JSON as HTML Middleware for: %s" % request.get_full_path()
response.content = "<html><head><title>%s</title></head><body>%s</body></html>" % (title, response.content)
response['Content-Type'] = 'text/html'

Django1.10引入了“新型中间件”：https://docs.djangoproject.com/en/2.0/releases/1.10/#new-style-middleware
这是一个新风格的中间件版本：
import json
from django.http import HttpResponse
class NonHtmlDebugToolbarMiddleware:
"""
The Django Debug Toolbar usually only works for views that return HTML.
This middleware wraps any non-HTML response in HTML if the request
has a 'debug' query parameter (e.g. http://localhost/foo?debug)
Special handling for json (pretty printing) and
binary data (only show data length)
"""
def __init__(self, get_response):
self.get_response = get_response
def __call__(self, request):
response = self.get_response(request)
if response['Content-Type'] == 'application/json':
content = response.content
try:
json_ = json.loads(content)
content = json.dumps(json_, sort_keys=True, indent=2)
except ValueError:
pass
response = HttpResponse('<html><body><pre>{}'
'</pre></body></html>'.format(content),
content_type='text/html')
return responsehttps://stackoverflow.com/questions/14618203
