我想在django管理站点中添加图像裁剪功能。我不知道我怎么能接近这个来完成它。我使用过django-image-cropping应用程序,但无法将其集成到管理员端。

您应该在模型中定义save()方法:
class MyImage(models.Model):
image = models.ImageField(...)
image_crop = models.ImageField(blank=True)
def save():
super(MyImage, self).save() #will save only image, image_corp will be blank.
image_path = self.image.path #path to your non croped image
#now you can load image file and crop it usung PIL and save.
self.image_crop = 'path/to/cropped/image' #add path to cropped image.
super(MyImage, self).save() #save data.
