'HttpResponse' hat kein Attribut '_get_content

Question

Ich benutze Django 1.5.1 und Piston für Rest Unterstützung mit MongoDB Datenbank.

Beim Versuch, die Rest-URL zum Abrufen der Daten zu testen, erhalte ich den folgenden Fehler.

type object 'HttpResponse' has no attribute '_get_content' 
Request Method: GET 
Request URL: http://127.0.0.1:8000/annotation/search?limit=20&uri=/document 
Django Version: 1.5.1

Python Executable: /home/tank/sites/python/env.example/bin/python

Das Problem wird in der Kolbencode generiert, nicht sicher, der Grund. Hier ist die vollständige Zurückverfolgungs

Answer 1

In Django 1.5 dieser Code:

def _get_content(self): 
    # do some stuff 

def _set_content(self): 
    # do some stuff 

content = property(_get_content, _set_content) 

wurde geändert in:

@property 
def content(self): 
    # do some stuff 

@content.setter 
def content(self, value): 
    # do some stuff 

Also, Django 1.5 hat keine _get_content Funktion. Sie sollten HttpResponseWrapper in Kolben/utils.py zu so etwas wie dies ändern:

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) 

Lassen Sie mich wissen, ob es funktioniert, werde ich verpflichten, dies zu piston Code.

Über das zweite Problem: vielleicht ist Ihre Version alt. Dieses Problem wurde bereits in this commit behoben.

Sie können dieses Problem lösen, indem auf die neueste Version dieses Kolbens Gabel Aktualisierung: https://github.com/marcio0/django-piston/
