jango 提交表单报错如下：
django CSRF Failed: CSRF token missing or incorrect
解决办法：
1. 打开setting.py 关于之前的csrf注释
MIDDLEWARE = [
'django.middleware.csrf.CsrfViewMiddleware',
]
2. 在form 表中中添加{%csrf_token %}
<form class="form-horizontal" id="addCrontabForm">
{%csrf_token %}
</form>
3. 如果通过ajax发送的post的请求 还需增加script 配置
$(document).ajaxSend(function(event, xhr, settings) {
function getCookie(name) {
var cookieValue =null;
if (document.cookie &&document.cookie !='') {
var cookies =document.cookie.split(';');
for (var i =0; i < cookies.length; i++) {
var cookie =jQuery.trim(cookies[i]);
// Does this cookie string begin with the name we want?
if (cookie.substring(0, name.length +1) == (name +'=')) {
cookieValue =decodeURIComponent(cookie.substring(name.length +1));
break;
}
}
}
return cookieValue;
}
function sameOrigin(url) {
// url could be relative or scheme relative or absolute
var host =document.location.host; // host + port
var protocol =document.location.protocol;
var sr_origin ='//' + host;
var origin = protocol + sr_origin;
// Allow absolute or scheme relative URLs to same origin
return (url == origin || url.slice(0, origin.length +1) == origin +'/') ||
(url == sr_origin || url.slice(0, sr_origin.length +1) == sr_origin +'/') ||
// or any other URL that isn't scheme relative or absolute i.e relative.
!(/^(\/\/|http:|https:).*/.test(url));
}
function safeMethod(method) {
return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
}
if (!safeMethod(settings.type) &&sameOrigin(settings.url)) {
xhr.setRequestHeader("X-CSRFToken", getCookie('csrftoken'));
}
});
