eug*_*ene 23 django debugging tastypie
django-debug-toolbar需要输出为html,但django-tastypie的默认输出格式是json.
我试过发送,http://localhost/api/v1/resource/?format=html但它说Sorry, not implemented yet. Please append "?format=json" to your URL
即使这个文档列出了html作为有效选项之一,它也说明了它TODO list.
http://django-tastypie.readthedocs.org/en/latest/serialization.html#to-html
如何使用调试工具栏来调试tastypie api调用？
(例如,我想看看为api调用运行了多少个sql查询..等等)
也许我可以从django视图中调用api但是如何？

这是我为类似目的编写的中间件,它在HTML中包装json以启用调试工具栏并且还可以打印它.此外,它支持二进制数据.我没有使用tastypie,但我认为它也应该适用.
# 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))
return response

Django调试工具栏的中间件实际上有代码,以防止它被激活为非类型的响应,如TastyPie返回的响应.我过去所做的是创建一些中间件,将json响应转换为HTML,这样工具栏就会被激活,我可以计算查询等......这有点像黑客,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'
return response
