如何在Django模型中删除ImageField图像 [英] How to delete an ImageField image in a Django model

问题描述

我有一个 Profile 模型，如下所示:

I have a Profile model like so:

class Profile(models.Model):
    photo = models.ImageField(upload_to="img/users/", blank=True)

我希望我的用户能够删除其个人资料照片，以使照片中没有图像，即空白.

I want my users to be able to remove their profile pictures so that there's no image in photo i.e blank.

我尝试了 Profile.objects.get(id = 1).photo.delete(save = False)，该操作删除了图像，但URL仍然存在，所以我得到了404.我清除图片和网址了吗?

I tried Profile.objects.get(id=1).photo.delete(save=False) which deleted the image but the url was still there so I was getting a 404. How do I clear the image and url?

编辑:在我的模板中，我喜欢:

In my template, I'm like:

{% if profile.photo %}
    <img src="{{ MEDIA_URL }}{{ profile.photo }}" />
{% else %}
    <img src="{{ MEDIA_URL }}img/avatar.jpg" />
{% endif %}

推荐答案

将 Profile.objects.get(id = 1).photo.delete(save = False)更改为 Profile.objects.get(id = 1).photo.delete(save = True)
