视图.views.create没有返回HttpResponse对象

Question

我是这种语言的新手，并尝试从我创建的2个模型中创建一个表单

models.py

from locpick.field import LocationField

from django.db import models

from django.db.models import permalink

from django.contrib import admin

from PIL import Image

from time import time

def get_upload_file_name(instance, filename):

     return "photo/%s_%s" % (str(time()).replace('.','_'), filename)

 class Journey(models.Model):

     name = models.CharField(max_length=250)

     location = LocationField()

     description = models.TextField()

     date = models.DateTimeField()

 class Meta:

      ordering = ['name']

 def __unicode__(self):

      return self.name

  @permalink

  def get_absolute_url(self):

       return ('item_detail', None, {'object_id': self.id})

  class Photo(models.Model):

       item = models.ForeignKey(Journey)

       upload = models.ImageField(upload_to=get_upload_file_name)

  class Meta:

       ordering = ['title']

  def __unicode__(self):

       return self.title

   @permalink

   def get_absolute_url(self):

        return ('photo_detail', None, {'object_id': self.id})

   class PhotoInline(admin.StackedInline):

        model = Photo

   class JourneyAdmin(admin.ModelAdmin):

         inlines = [PhotoInline]

         list_display = ('name', 'location','description')

   admin.site.register(Journey, JourneyAdmin)

表格

   from django import forms

   from models import Journey, Photo

   class JourneyForm(forms.ModelForm):

     class Meta:

         model = Journey

         fields = ('name','location','description','date')

   class PhotoForm(forms.ModelForm):

       class Meta:

            model = Photo

            exclude = ('item')

views.py

     from django.template import loader, Context

     from django.shortcuts import render_to_response

     from django.http import HttpResponseRedirect

     from django.shortcuts import render_to_response

     from django.http import HttpResponse

     from locpick.models import Journey , Photo

     from forms import JourneyForm, PhotoForm

     from django.core.context_processors import csrf

我收到创建ddidnt返回HttpResponse对象的错误

我要去哪里错了
