django-blog（七）上传图片

1、在settings.py中配置MEDIA_URL和MEDIA_ROOT

[root@localhost blogproject]# 

[root@localhost blogproject]# vim blogproject/settings.py

MEDIA_URL = '/uploads/'

MEDIA_ROOT = os.path.join(BASE_DIR,  'uploads')

 

2、urls.py中配置路由

django1.9及以下

url(r"^uploads/(?P<path>.*)$", \

                "django.views.static.serve", \

                {"document_root": settings.MEDIA_ROOT,}),

djaggo1.10及以上

from django.conf.urls.static import static

urlpatterns = [

    url(r'^admin/', admin.site.urls),

    url(r'^$',index,name='index'),

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

3、在model中设置图片的上传位置和路径

[root@localhost kindeditor-4.1.10]# cd /root/blogenv/blog_env/blogproject/static/js/kindeditor-4.1.10

[root@localhost kindeditor-4.1.10]# vim config.js 

KindEditor.ready(function(K) {

                window.editor = K.create('#id_content',

{

width : '900px',

height : '300px',

uploadJson: '/admin/upload/kindeditor',

}

);});

 

urls配置：

 

from django.conf.urls import url

from django.contrib import admin

from blog.views import *

from django.conf import settings

from blog.upload import upload_image

from django.conf.urls.static import static

urlpatterns = [

    url(r'^admin/', admin.site.urls),

    url(r'^$',index,name='index'),

    url(r'^admin/upload/(?P<dir_name>[^/]+)$', upload_image, name='upload_image'),

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