我正在为我的网站制作个人资料页面。我在网上按照几个人的指示做了他们所说的（即 media_url、media_root、对我的 urls.py 的更改）。我通过管理页面注册了我的超级用户，并为它提供了个人资料。尝试获取我的图像时，它不显示。这是我的代码：

模型.py

from django.db import models
from django.contrib.auth.models import User

# Create your models here.

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    Pic = models.ImageField(default='default.png', blank=True, upload_to='img')
    address = models.CharField(max_length=70, default='Bensons', unique=True)
    email = models.EmailField(max_length=70, unique=True, default='[e-mail]')

    def __str__(self):

        return self.address

模板/profile.html

% extends 'index/base.html' %

% block content %
  <div class='container'>

    <img src=' user.Profile.Pic.url ' width='240'

  </div>
% endblock %

view.py

@login_required
def Profile_view(request):
    user = User

    return render(request, 'index/profile.html', 'title': 'profile', 'user' : user)

我认为这是模板中的问题，但我不确定。当我尝试在管理员中打开图像时，它工作正常。

【问题讨论】：

检查图像元素并检查图像的路径并验证该路径中是否存在图像

还有img 缺少结束标签

当我检查元素时它说

图片来源未知，因为你的表Profile中没有名为url的列；而不是 user.Profile.url 你必须写 user.Profile.pic.url

您在Pic中添加了图片，因此图片路径是user.profile.Pic.url而不是user.profile.url

【参考方案1】：

尝试在命令终端中使用此命令安装枕头： pip install pillow

【参考方案2】：

你指定了

class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
# <----There doesn't seem to be a url field on the model
Pic = models.ImageField(default='default.png', blank=True, upload_to='img')
address = models.CharField(max_length=70, default='Bensons', unique=True)
email = models.EmailField(max_length=70, unique=True, default='[e-mail]')

def __str__(self):

    return self.address

模板

改变

<img src=' user.Profile.url ' width='240' />

到

<img src=' user.Profile.Pic.url ' width='240' />

https://docs.djangoproject.com/en/2.1/ref/models/fields/#django.db.models.FileField.storage

【讨论】：

“url 字段”是什么意思

user.Profile.url 不是您的配置文件模型上的图像字段

如何添加

@abhinavchavali ‘url’ 给出了存储在 media/img 文件夹中的图像的相对路径

@KeshavGarg 它仍然无法正常工作。我的设置、网址或视图是否有问题
