在Django中上传Cloudinary多张图片？

Question

我在带有Cloudinary包的Django应用中定义了如下图像上传，

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

我想使该字段上载多幅图像。我该怎么做呢？

Answer 1

包含多张图像的照片将成为相册或相册。我将重塑所有如下：

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知道了PhotoAlbum：

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

将PhotoAlbum跟踪所有的PhotoS：

>>> 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
