Question

我想使用django和django rest-framework在亚马逊s3上传图像文件。以下是我项目的代码片段。

models.py

class Image(models.Model):
    image_meta = models.ForeignKey('Image_Meta',on_delete=models.CASCADE,)
    image = models.ImageField(upload_to='images-data')
    order = models.IntegerField()
    version = models.CharField(max_length=10)

serializers.py

class ImageSerializer(serializers.ModelSerializer):
    class Meta:
        model = Image
        field = ('id', 'image_path' , 'order' , 'version')

urls.py

from django.conf.urls import patterns , include , url
from rest_framework.urlpatterns import format_suffix_patterns
from imagedata import  views

urlpatterns = patterns('',
    url(r'^image/$',views.ImageList.as_view(),name='image_list'),
    url(r'^image/(?P<pk>[0-9]+)/$',views.ImageDetail.as_view(),name='image_detail'),
)

urlpatterns = format_suffix_patterns(urlpatterns)

views.py

@api_view(('GET',))
def api_root(request, format=None):
    return Response({
        'Component': reverse('component_list', request=request),
        'Image Type': reverse('imagetype_list', request=request),
        'Image Component':reverse('imagecomponent_list' , request=request),
        'Feature':reverse('feature_list',request=request) 
    })
class ImageList(generics.ListCreateAPIView):
    queryset = Image.objects.all()
    serializer_class = ImageSerializer
    parser_classes = (MultiPartParser)

class ImageDetail(generics.RetrieveUpdateDestroyAPIView):
    queryset = Image.objects.all()
    serializer_class = ImageSerializer

try:
    from local_settings import *
except ImportError:
    pass

assert len(SECRET_KEY) > 20, 'Please set SECRET_KEY in local_settings.py'

local_settings.py

AWS_S3_ACCESS_KEY_ID = 'Get this from Amazon'
AWS_S3_SECRET_ACCESS_KEY = 'This as well'
AWS_STORAGE_BUCKET_NAME = 'your-s3-bucket-name'
SECRET_KEY = '****secret_key****'

完成所有这些后，我陷入了下一步。我想做的就是将图像从本地系统上传到s3到Django。我一直在使用this作为参考。
