Django:图像字段未显示

Django: Image Field not showing up

所以我的图片没有显示,这是我的代码: models.py:

from django.contrib.auth.models import User
from django.db import models
from django.conf import settings
from django.utils.translation import gettext_lazy as _

class ProfileImage(models.Model):
    """
    Profile model
    """
    user = models.OneToOneField(
        verbose_name=_('User'),
        to=settings.AUTH_USER_MODEL,
        related_name='profile',
        on_delete=models.CASCADE
    )
    avatar = models.ImageField(upload_to='profile_image')

settings.py:

MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'mifamiliaesundesastre/media')

urls.py:

from django.contrib import admin
from django.urls import path, include
from Home.views import home_view
from accounts.views import login_view, register_view, logout_view, user_home
from chat.views import Messages

from django.conf import settings
from django.conf.urls.static import static

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', home_view, name='home'),
    path('login/', login_view),
    path('signup/', register_view),
    path('logout/', logout_view),
    path('home/', user_home),
    path('messages/', include('chat.urls')),
    path('messages/', Messages),
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

user_home.html:

 <img src="{{ user.profileimage.avatar.url }}" alt="profile image">

我做对了,我也可以在我的媒体文件夹中看到我的图像,但在我的模板中没有显示, 有人知道我的代码有什么问题吗?

由于 ForeignKey 中的 related_name='profile''profile',您可以使用

访问它
<img src="{{ user.<b>profile</b>.avatar.url }}" alt="profile image">

related_name=… parameter [Django-doc]reverse 中关系的名称。所以要从User对象中获取相关的ProfileImage对象。

您也可以决定将related_name=…更改为related_name='profileimage',那么您当然会使用{{ user.profileimage.avatar.url }}
