我正在为我的网站创建个人资料页面。我已经按照网上几个人的指示进行操作，并且按照他们说的做（即media_url，media_root和对urls.py的更改）。我通过管理页面注册超级用户，并为其提供了个人资料。尝试获取我的图像时，它不会显示。这是我的代码：

Models.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='ben@email.com')

    def __str__(self):

        return self.address

{% block content %}

{% 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admin中打开图像时，效果很好。

Answer 1

您指定了

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='ben@email.com')

def __str__(self):

    return self.address

模板

更改

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

收件人

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

Answer 2

尝试在命令终端中使用此命令安装枕头： pip install pillow

图像未出现在Django 2.1的模板中
