mysql - I set a key in django's request.session , but has no effect -

i set jobfile key in session below:

def getjoblist(request):     joblist = request.get.get('job')     jobliststr = joblist[0:-1]     request.session['jobfile'] = jobliststr     return httpresponse("ok\n") 

and check mysql database, rows increment, when test key ,it shows key not in session:

if request.session.has_key('jobfile'): # return false; 

i didn't know why?

you may need save session after adding new key

request.session['jobfile'] request.session.save()
