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
我是新用django和谷歌应用引擎。我无法查询数据库。我收到这个错误：
Exception Type: ValueError
Exception Value: too many values to unpack
直接在shell中进行查询我得到了这个：
>>> uno = ligas.objects.all()[0]
>>> uno.liga
u'www.yahoo.com'
>>> uno.llave
u'yahoo'
我无法弄清楚我的错误。 请帮助。
