Django 中使用ImgFiled 和FileFiled

1、使用ImgFiled

class ImageField(upload_to=None, height_field=None, width_field=None, max_length=100, **options)[source]¶  返回资源

必须在setting.py 中设置MEDIA

setting.py

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

models.py

cover_map = models.ImageField(verbose_name='缩列图',upload_to='article/%Y/%m/%d',default='1.png')

upload_to   上传的位置   最后会上传到  /meta/article/年/月/日/**.jpg  

如果要显示需要在urls.py设置

from django.contrib import admin
from django.urls import path
from django.urls import include
from django.conf import settings
from django.conf.urls.static import static

urlpatterns = [
    path('admin/', admin.site.urls),
    path('polls/', include('polls.urls')),
    path('download/', include('download.urls')),
    path('article/', include('article.urls')),
]+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
