Question

我正在使用django 1.7和Tastypie 0.12.0每当我尝试POST到django-tastypie时，都没有创建对象，并且我在此响应时出现500错误：

{"error_message": "add() argument after * must be a sequence, not Comment", "traceback": "Traceback (most recent call last):

我不想让帖子混乱，所以如果你需要查看特定的代码，请告诉我。

这是我的模特：

class Comment(models.Model):
    post = models.ForeignKey(NewsFeedPost, related_name='comments', null=True, blank=True)
    comment_by = models.ForeignKey(settings.AUTH_USER_MODEL, related_name='comments', null=True, blank=True)
    timestamp = models.DateTimeField(null=True, blank=True)   
    body = models.CharField(max_length=1000, null=True, blank=True)
    hashtags = models.ManyToManyField(Hashtag, related_name='comments', null=True, blank=True)

我的资源：

class CommentResource(ModelResource):
    post = fields.ForeignKey('newsfeed.api.NewsFeedPostResource', 'post', related_name='comments',
                             null=True, blank=True, full=True)
    comment_by = fields.ForeignKey('login.api.UserResource', 'comment_by', related_name='comments',
                                   null=True, blank=True, full=True)
    hashtags = fields.ManyToManyField('newsfeed.api.HashtagResource', 'hashtag_set',
                                      related_name='comments', null=True, blank=True, full=True)

    class Meta:
        queryset = Comment.objects.all()
        resource_name = 'comments'
        authorization = Authorization()
        filtering = {
            "post": ALL_WITH_RELATIONS
        }
        allowed_methods = ['get', 'post', 'put']

500错误POST到Django-Tastypie
