models.py

from django.db import models
from google.appengine.ext import db

class ligas(models.Model):
    llave = models.TextField()
    liga = models.TextField()

views.py

from django.http import Http404, HttpResponse
from google.appengine.ext import db
from models import ligas

def liga(request, offset):
    dt = get_url(offset)
    html = "<html><body>la liga para %s es %s</body></html>" % (offset, dt)
    return HttpResponse(html)

def get_url(valor):
    direc = ''
    q = ligas.objects.all()
    q.filter("llave=", valor)
    direc = q.get()
    return direc.liga

直接在shell中进行查询，我得到以下结果：

>>> uno = ligas.objects.all()[0]
>>> uno.liga
u'www.yahoo.com'
>>> uno.llave
u'yahoo'

我想不出我做错了什么。请帮忙

这个

应该是

q.filter(llave=valor)

您好，欢迎光临，请发布整个回溯，而不仅仅是最后一行。这将帮助别人帮助你！您正在使用云sql吗？

q.filter("llave=", valor)

q.filter(llave=valor)
