在编辑记录时,如果等待几分钟(喝咖啡)然后再回来按下保存(POST),我会被重定向到主页面而不是登录而数据丢失.
似乎烧瓶登录会话过期太快了.
我做了一些研究并遇到了这个问题.
from flask import session,app session.permanent = True
这是正确的方法吗？但即使我尝试这个,我得到这个例外：
File "/Users/kave/workspace/F11A/src/application/__init__.py",line 14,in <module>
session.permanent = True
File "/Users/kave/workspace/F11A/src/lib/werkzeug/local.py",line 355,in <lambda>
__setattr__ = lambda x,n,v: setattr(x._get_current_object(),v)
File "/Users/kave/workspace/F11A/src/lib/werkzeug/local.py",line 297,in _get_current_object
return self.__local()
File "/Users/kave/workspace/F11A/src/lib/flask/globals.py",line 20,in _lookup_req_object
raise RuntimeError('working outside of request context')
RuntimeError: working outside of request context
解决方法
以防万一其他人会有这个问题.我想Hooman已经得到了答案.
不会工作
views.py
from flask import session from datetime import timedelta session.permanent = True app.permanent_session_lifetime = timedelta(minutes=30)
将工作
from flask import session
from datetime import timedelta
@app.route('/home',methods=['GET','POST'])
def show_work():
session.permanent = True
app.permanent_session_lifetime = timedelta(minutes=30)
form = MyForm(request.form)
return render_template('home.html',form = form)
会话必须在请求中使用.
