Question

我在我的带有Cloudinary包的Django应用程序中定义了如下图像上传，

class Photo(models.Model):
    photo = CloudinaryField('image')

我想让这个字段上传多个图像。我该怎么做呢？

Answer 1

包含多张图片的照片会成为相册或照片库。我改造了以下内容：

class PhotoAlbum(models.Model):
    name = models.CharField()  # or whatever a photo album has

class Photo(models.Model):
    file = CloudinaryField('image')
    album = models.ForeignKey(PhotoAlbum, on_delete=models.CASCADE, related_name='photos')

用法示例：

>>> album = PhotoAlbum.objects.create(name='myalbum')
>>> photo = Photo.objects.create(album=album, image=...)

现在，Photo知道其PhotoAlbum：

>>> photo = Photo.objects.first()
>>> photo.album
<PhotoAlbum: myalbum>

PhotoAlbum会跟踪所有Photo s：

>>> album = PhotoAlbum.objects.first()
>>> album
<PhotoAlbum: myalbum>
>>> album.photos.all()
<QuerySet [<Photo: Photo-1>]>
>>> album == Photo.objects.first().album
>>> True
>>> Photo.objects.first() == album.photos.first()
>>> True

Answer 2

我会这样做：

class Photo(models.Model):
    photos = models.ManyToManyField('ChildPhoto',blank=True)

class ChildPhoto(models.Model):
    photo = CloudinaryField('image')

您可以上传许多照片，而照片模型将与ChildPhoto模型相比具有更多优势
