我正在使用Django 1.5.1和Piston来支持MongoDB数据库。
当尝试测试其余网址以检索数据时,我收到以下错误。
type object 'HttpResponse' has no attribute '_get_content'
Request Method: GET

问题是在活塞代码中产生的,不确定原因。这是完整的追溯

184. if isinstance(result, HttpResponse) and not result._is_string:
Exception Type: AttributeError at /annotations/search
Exception Value: 'HttpResponseWrapper' object has no attribute '_is_string'
答案 0 :(得分:3)
在Django 1.5中这段代码:
def _get_content(self):
# do some stuff
def _set_content(self):
# do some stuff
content = property(_get_content, _set_content)
更改为:
@property
def content(self):
# do some stuff
@content.setter
def content(self, value):
# do some stuff
因此,Django 1.5没有_get_content
功能。您应该将 piston / utils.py 中的HttpResponseWrapper
更改为以下内容:
class HttpResponseWrapper(HttpResponse):
"""
Wrap HttpResponse and make sure that the internal
_is_string/_base_content_is_iter flag is updated when the
_set_content method (via the content property) is called
"""
def _set_content(self, content):
"""
Set the _container and _is_string /
_base_content_is_iter properties based on the type of
the value parameter. This logic is in the construtor
for HttpResponse, but doesn't get repeated when
setting HttpResponse.content although this bug report
(feature request) suggests that it should:
http://code.djangoproject.com/ticket/9403
"""
is_string = False
if not isinstance(content, basestring) and hasattr(content, '__iter__'):
self._container = content
else:
self._container = [content]
is_string = True
if django.VERSION >= (1, 4):
self._base_content_is_iter = not is_string
else:
self._is_string = is_string
try:
# Django versoin is older than 1.5
content = property(HttpResponse._get_content, _set_content)
except:
# Django version 1.5
@HttpResponse.content.setter
def content(self, content):
self._set_content(content)
如果有效,请告诉我,我会将其提交给piston
代码。
关于第二个问题:也许,你的版本已经过时了。此问题已在this提交中解决。
答案 1 :(得分:0)
您可以通过更新到此活塞前叉的最新版本来解决此问题: https://github.com/marcio0/django-piston/
