在我的 django webapp 中向 api 发出 post 请求时出现错误，我正在为 api 使用tastepie 并出现以下错误。

发布请求

curl --dump-header - -H "Content-Type: application/json" -X POST --data '{"title": "Post Title 1", "video": "http://www.youtube.com/watch?v=0u03h73ClZ8", "artist": "artist_name 1"}' "http://127.0.0.1:8000/api/v1/video/" -u "username:password"

错误

模型.py

class Artist(models.Model):
    name = models.CharField(max_length=255)

    def __unicode__(self):
        return unicode(self.name)

class Video(models.Model):
    title = models.CharField(max_length=255)
# url Should be a valid youtube URL
    video = EmbedVideoField()
    artist = models.ForeignKey(Artist)
    slug = AutoSlugField(populate_from='title', unique=True)

     # SLUG depends on title
    def __unicode__(self):
    return unicode(self.title)

api.py

class ArtistResource(ModelResource):
    class Meta:
        queryset = Artist.objects.all()
        resource_name = 'artist'

class VideoResource(ModelResource):
    artist = fields.ForeignKey(ArtistResource, 'artist')

    class Meta:
         queryset = Video.objects.all()
         resource_name = 'video'
         authorization = DjangoAuthorization()
         authentication = BasicAuthentication()

您发布数据：

{
    "title": "Post Title 1",
    "video": "http://www.youtube.com/watch?v=0u03h73ClZ8",
    "artist": "artist_name 1"
}

将艺术家属性更改为：

"artist": {"name": "artist_name 1"}

或资源的网址：

"artist": "/api/v1/user/1/"
