获取全局配置 （上下文渲染器）
# settings.py
SITE_NAME = 'My Blog'
'context_processors': ['blog.views.global_settings']
#
# blog.views.py
def global_settings():
return {'site_name': settings.SITE_NAME}
#
# index.html
{{ site_name }}
扩展 User
# models.py
from django.contrib.auth.models import AbstractUser
class User(AbstracUser):
qq
mobile
#
# settings.py
AUTH_USER_MODEL = 'blog.User'
富文本编辑器
# admin.py
class Media:
js = (' ../kindeditor-min.js', '../lang/zh_CN.js', 'config.js') // config.js 是自己创建的
#
# config.js
KindEditor.ready(function(K) {
window.editor = K.create('textarea[name=content]', {width: '500px', height: '200px'});
});
上传文件
# 开启
# settings.py
MEDIA_URL = '/uploads/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'uploads')
#
# urls.py
url(r'^uploads/(?P<path>.*)$,'django.views.static.serve', {'document_root': settings.MEDIA_ROOT, })
# models.py
avatar = models.ImageField(upload_to='avatar/%Y/%m') // 求测试没有配置情况
集成 kindeditor
# 配置 url
url(r'^admin/upload/(?P<dir_name>[^/]+)$', upload_image, name='upload_image')
# 配置 config.js
uploadJson: '/admin/upload/kindeditor'
# 创建 blog/upload.py 文件
