python - 我如何在模型中使用图像

Django 找不到图片 settings.py 的路径

网址.py

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

app_name = 'homepage'
urlpatterns = [
    path('', views.home, name = 'home'),
    path('patch', views.patch, name = 'patch'),
    path('patch/patch<int:patch_id>', views.patches, name = 'patches'),
    path('champ', views.champ, name = 'champ'),
    path('champ/champ<int:champ_id>', views.champs, name = 'champs'),
    path('ivent', views.ivents, name = "ivents"),
    path('ivent/ivent<int:ivent_id>', views.ivent, name = 'ivent'),
    path('item', views.items, name = 'items'),
    path('item/item<int:item_id>', views.item, name = 'item'),
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

当我运行该站点时，控制台显示“未找到 /media/homepage/Azir.jpg”。我不明白为什么 django 找不到沿着这条路径的图像。我做的最后一件事是添加

+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

在 urls.py 中，但没有任何改变。我认为这可能是 settings.py 的错误。也许我写错了 MEDIA_ROOT 或其他东西，因此 django 找不到图像的路径
