在Django Admin中上传多个图像 [英] Upload multiple images in Django Admin

问题描述

models.py

class Video(models.Model):
    title = models.CharField(max_length=100, blank=True, default='')
    details = models.TextField()

class VideoDetails(models.Model):
    video = models.ForeignKey(Video, on_delete=models.CASCADE, related_name='videos')
    images = models.ImageField(upload_to='images/video/%Y/%m/%d')

serializers.py

class VideoDetailsSerializer(serializers.ModelSerializer):
    class Meta:
        model = VideoDetails
        fields = '__all__'

class VideoSerializer(serializers.ModelSerializer):
    class Meta:
        model = Video
        fields = '__all__'

admin.py

class VideoDetailsInline(admin.TabularInline):
    model = VideoDetails

class VideoAdmin(admin.ModelAdmin):
    inlines = [VideoDetailsInline]

admin.site.register(Video, VideoAdmin)

如上所述，我上传了3张图像用于视频2。但是，在我的 VideoList 视图中，我没有得到这些图像的URL。

As shown above, I uploaded 3 images for video 2. However, in my VideoList view, I didn't get the urls of those images.

views.py

class VideoList(viewsets.ModelViewSet):
    serializer_class = VideoSerializer
    queryset = Video.objects.all()

如何我可以将 VideoDetail 中的图像网址附加到 Video queryset 中c>？需要您的帮助...

How can I attach those image url in VideoDetail to the queryset of Video? Need your help...

推荐答案

根据该更改文件，不要忘记配置 MEDIA_URL

Change your files according to that and don't forget configure a MEDIA_URL

models.py

import os
from django.conf import settings

class VideoDetails(models.Model):
    video = models.ForeignKey(Video, on_delete=models.CASCADE, related_name='videos')
    images = models.ImageField(upload_to='images/video/%Y/%m/%d')

    def get_absolute_image_url(self):
        return os.path.join(settings.MEDIA_URL, self.images.url)

serializers.py

class VideoDetailsSerializer(serializers.ModelSerializer):

    image_url = serializers.URLField(source='get_absolute_image_url', read_only=True)

    class Meta:
        model = VideoDetails
        fields = ('video', 'image_url')


class VideoSerializer(serializers.ModelSerializer):

    video_details = VideoDetailsSerializer(many=True, read_only=True)

    class Meta:
        model = Video
        fields = ('title', 'details', 'video_details')
