1.Crsf

Extjs里面所有的表单都是通过Ajax提交的，所以会被Crsf所拦截

所以在每个页面需要引入如下js，主要是在提交表单时设置 crsf信息

//crsf验证Ext.Ajax.on('beforerequest', function (conn, options) {    if (!(/^http:.*/.test(options.url) || /^https:.*/.test(options.url))) {        if(Ext.util.Cookies.get('csrftoken')==null){            Ext.util.Cookies.set('csrftoken','csrftoken')        }        if (typeof(options.headers) == "undefined") {            options.headers = {'X-CSRFToken': Ext.util.Cookies.get('csrftoken')};        } else {            options.headers['X-CSRFToken']=Ext.util.Cookies.get('csrftoken');        }    }}, this);

2. 封装Json结果和Ajax请求装饰器

import datetimeimport decimalfrom django.http import Http404, HttpResponsefrom django.utils import simplejsonfrom django.utils.timezone import is_awarefrom django.db import modelsfrom science import settingsfrom const import Constfrom django.core.serializers import serializefrom django.utils.simplejson import dumps, loadsfrom django.db.models.query import QuerySet, ValuesQuerySetfrom django.utils.functional import curryclass DjangoJSONEncoder(simplejson.JSONEncoder):"""JSONEncoder subclass that knows how to encode date/time and decimal types."""def default(self, o):# See "Date Time String Format" in the ECMA-262 specification.if isinstance(o, datetime.datetime):return o.strftime('%Y年%m月%d日')elif isinstance(o, datetime.date):return o.isoformat()elif isinstance(o, datetime.time):if is_aware(o):raise ValueError("JSON can't represent timezone-aware times.")r = o.isoformat()if o.microsecond:r = r[:12]return relif isinstance(o, decimal.Decimal):return str(o)elif isinstance(o,ValuesQuerySet):return list(o)elif isinstance(o, QuerySet):return loads(serialize('json', o))elif isinstance(o, models.Model):return dict([(attr, getattr(o, attr)) for attr in [f.name for f in o._meta.fields]])else:return super(DjangoJSONEncoder, self).default(o)dumps = curry(dumps, cls=DjangoJSONEncoder)def Ajax(fn):def wrapper(*args, **kv):request = args[0]if not  settings.DEBUG and\not request.is_ajax():raise Http404result= fn(*args, **kv)result=dumps(result)return HttpResponse(result,mimetype="application/json")return wrapper
