python - 如何为django应用程序设置图片上传根目录

Question

我无法为上传的图片设置根文件夹。上传图片在名为 api 的 django 应用程序中。

View 在图像上返回此链接: http://www.example.com/media/4a273bdf-564d-4dec-b657-43db27f04042.jpeg

但是，当我继续该链接时，出现错误，因为图像不在那里。

我在settings.py中设置:

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'static/')
REST_FRAMEWORK = {
    'DEFAULT_PERMISSION_CLASSES': [
        'rest_framework.permissions.IsAdminUser',
    ],
    'PAGE_SIZE': 1
}

MEDIA_ROOT = os.path.join(BASE_DIR,STATIC_ROOT,'media')
MEDIA_URL = '/media/'

我在 api/models.py 中写了这个:

from django.db import models
import uuid

def scramble_uploaded_filename(instance, filename):
    extension = filename.split(".")[-1]
    return "{}.{}".format(uuid.uuid4(), extension)

def filename(instance, filename):
    return filename

# Create your models here.
class UploadImage(models.Model):
    image = models.ImageField("Uploaded image",upload_to=scramble_uploaded_filename)
    captcha_type = models.IntegerField("Image type")

View .py

from rest_framework import viewsets
from api.models import UploadImage
from api.serializers import UploadedImageSerializer
from rest_framework import authentication, permissions
from rest_framework.parsers import MultiPartParser,FormParser
import MySQLdb

class FileUploadViewSet(viewsets.ModelViewSet):
    #create queryset view
    permission_classes = (permissions.IsAuthenticated,)
    queryset = UploadImage.objects.filter(id=1,user='auth.User')
    serializer_class = UploadedImageSerializer
    parser_classes = (MultiPartParser, FormParser,)

序列化器.py

from rest_framework import serializers
from api.models import UploadImage # Import our UploadedImage model

class UploadedImageSerializer(serializers.ModelSerializer):
    # current_user = serializers.HiddenField(default=serializers.CurrentUserDefault())
    class Meta:
        model = UploadImage
        fields = ('id', 'image','captcha_type','created','user','result') #

有什么想法吗？

嗨，m8，你所要做的就是编辑 urls.py 添加这几行，它应该可以工作。

from django.conf.urls import include, url
from django.contrib import admin
from django.conf.urls.static import static
from django.conf import settings

urlpatterns = [
   url(r'^admin/', admin.site.urls),
]+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
