标签: django imagefield

所以我的图像没有显示,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">

我做了所有正确的操作,也可以在媒体文件夹中看到我的图像,但是我的模板中没有显示, 有人知道我的代码有什么问题吗?

答案 0 :(得分:1)

for(p in 1:3) { x <- lapply(list, function(l) list(get(paste0("x",l)))) } 中将related_name='profile'设为ForeignKey,您可以使用

'profile'

related_name=… parameter [Django-doc] reverse 中关系的名称。因此,要从<img src="{{ user.profile.avatar.url }}" alt="profile image">对象获得相关的ProfileImage对象。

您还可以决定将User更改为related_name=…,然后当然使用related_name='profileimage'
