每次尝试加载主页时，我都会收到这个错误。这是我从chrome调试器得到的错误：
The 'poster' attribute has no file associated with it.

During handling of the above exception ('ImageFieldFile' object is not subscriptable), another exception occurred
这是我的型号.py:
class Pilot(models.Model):
title = models.CharField(max_length=200)
description = models.TextField()
count = models.IntegerField()
writer = models.CharField(max_length=200)
year = models.IntegerField()
script = models.FileField(blank=True, null=True, upload_to="scripts")
poster = models.ImageField(blank=True, null=True, upload_to="posters")
created_at = models.DateTimeField(auto_now_add=True)
updated_at = models.DateTimeField(auto_now=True)
我的网址.py:
from django.contrib import admin
from django.urls import path, include
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('script_app.urls')),
]
if settings.DEBUG:
urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
我的设置.py：STATIC_URL='/STATIC/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
MEDIA_URL = '/media/'
STATICFILES_DIR = [
os.path.join(BASE_DIR, 'static')
]
我不知道是什么绊倒了。有人能告诉我怎么了吗？！！！！
poster = models.ImageField(blank=True, default='default.png', upload_to="posters")
每次jinja循环试图解析图像时，都会向您显示错误，如果他们没有发现任何错误，就会显示错误。为了防止这种情况，您可以上传所有图像，或者在海报文件夹中设置默认.png。
在Html代码中，｛%load-static%｝总是位于顶部，而您将其放在中间，这是加载静态文件的错误之处。
{% load static %}
<!DOCTYPE html>
2 <html lang="en">
3 <head>
4 <meta charset="UTF-8">
5 <meta name="viewport" content="width=device-width, initial-scale=1.0">
6 <title>Episode One</title>
8 <link rel="stylesheet" type="text/css" href="{% static 'css/main.css' %}">

在设置中。请尝试这个
STATIC_URL = '/static/'
STATIC_ROOT= os.path.join(BASE_DIR, "static", "static_root")
STATICFILES_DIRS = [
os.path.join(BASE_DIR, "static"),
]
试试我上面所做的。它会帮助你的。
