我正在遵循 django-tastypie 的教程，在连接资源之后，我去了http://localhost:8000/api/entry/?format=json，我在 JSON 中收到了这个错误：
{"error_message": "maximum recursion depth exceeded", "traceback": "Traceback (most recent call last):\n\n File \"C:\\Python27\\lib\\site-packages\\django_tastypie-0.9.14-py2.7.egg\\tastypie\\resources.py\", line 202, in wrapper\n response = callback(request, *args, **kwargs)\n\n\
模型.py：
from tastypie.utils.timezone import now
from django.contrib.auth.models import User
from django.db import models
from django.template.defaultfilters import slugify
class Entry(models.Model):
user = models.ForeignKey(User)
pub_date = models.DateTimeField(default=now)
title = models.CharField(max_length=200)
slug = models.SlugField()
body = models.TextField()
def __unicode__(self):
return self.title
def save(self, *args, **kwargs):
# For automatic slug generation.
if not self.slug:
self.slug = slugify(self.title)[:50]
return super(Entry, self).save(*args, **kwargs)
api.py：
from tastypie.resources import ModelResource
from myapp.models import Entry
class EntryResource(ModelResource):
class Meta:
queryset = Entry.objects.all()
resource_name = 'entry'
