在Django的ImageField中使用已经上传的图像 [英] Use already uploaded image in Django's ImageField

问题描述

ImageField中是否可以设置路径或已上传的图像?

Is there an option in ImageField to set the path or an already uploaded image?

我的用例如下:我想在两个不同的内容条目中重新使用同一图像.我不想上传图片两次，也不想存储同一图片的两个副本.

My use case is as follows: I want to reutilize the same image in two different content entries. I don't want to upload the image twice or to store two copies of the same image.

推荐答案

只需将图像字段从一个模型实例分配给另一个:

Just assign the image field from one model instance to another:

original_entry = Entry.objects.get(pk=1)

another_entry = Entry.objects.get(pk=2)
another_entry.image = original_entry.image
another_entry.save()

new_entry = Entry.objects.create(image=original_entry.image)
