python - 错误 : object has no attribute 'get_via_uri' "in post object in tastypie

Question

我是 django 的新手，在发布数据时遇到错误:

{    "name": "My family",
     "title": "Wassup",
     "gallery":"/api/v1/gallery/1/"
}

到终点:http://127.0.0.1:8000/api/v1/images/
"error_message": "'Gallery' 对象没有属性 'get_via_uri'"

模型.py

class Gallery(models.Model):
    name = models.CharField(max_length=64)

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


class Image(models.Model):
    gallery = models.ForeignKey(Gallery)
    name = models.CharField(max_length=64)
    title = models.CharField(max_length=255)

资源.py

class GalleryResource(ModelResource):
    images = fields.ToManyField(
        'gallery_app.resources.ImageResource',
        'images',
        full=True)

    class Meta:
        queryset = Gallery.objects.all()
        authorization = Authorization()
        resource_name = 'gallery'


class ImageResource(ModelResource):
    gallery = fields.ForeignKey(Gallery, 'gallery')

    class Meta:
        queryset = Image.objects.all()
        authorization = Authorization()
        resource_name = 'images'

点卡住

Django==1.6.5
Pillow==2.5.1
South==1.0
argparse==1.2.1
django-tastypie==0.11.1
python-dateutil==2.2
python-mimeparse==0.1.4
six==1.7.3
wsgiref==0.1.2

请推荐一些基于tastypie api的好项目供引用。谢谢。

Answer 1

您指的是 ImageResource 中的模型库，您应该指的是 GalleryResource。

class ImageResource(ModelResource):
  gallery = fields.ForeignKey(GalleryResource, 'gallery')

  class Meta:
    queryset = Image.objects.all()
    authorization = Authorization()
    resource_name = 'images'
