我有非常简单的应用程序，其中匿名用户张贴建议和主持人指定接收到的建议（状态是：0,1,2,3）的状态。瓶：记录没有立即更新
我使用烧瓶管理员给管理员定制列表视图（我添加了4个按钮的每个状态）
from flask import Flask,request,url_for,redirect
from Admin.Admin import admin,init_login
from Model import db,suggestion,User
import geoip2.webservice
app = Flask(__name__)
app.config.from_pyfile('Config.cfg')
db.init_app(app)
app.config['SQLALCHEMY_POOL_SIZE'] = 100
app.config['SQLALCHEMY_POOL_RECYCLE'] = 100
init_login(app)
admin.init_app(app)
IPclient = geoip2.webservice.Client("XXX")
def UpdateRecord(ID,status):
try:
Record = suggestion.query.filter_by(id=ID).first()
Record.Flag=status
db.session.commit()
except Exception, r:
raise r
#db.session.flush()
#Record = suggestion.query.filter_by(id=id).first_or_404()
#Record.Flag=1
#db.session.commit()
@app.route('/')
def index():
return redirect("sometime ... ")
@app.route("/XXXX/Favorite/<int:id>")
def favorite(id):
UpdateRecord(id,1)
return redirect(url_for("admin.index")+"Favsuggestion")
@app.route("/XXXX/Archive/<int:id>")
def archive(id):
UpdateRecord(id,2)
return redirect(url_for("admin.index")+"Arcsuggestion")
@app.route("/WSC/Published/<int:id>")
def published(id):
UpdateRecord(id,3)
return redirect(url_for("admin.index")+"Pubsuggestion")
@app.route("/suggest",methods=["GET","POST"])
def suggest():
try:
db.session.flush()
suggestionString=request.form.get('suggestionString')
IpAddress=request.remote_addr
IPresponse = IPclient.city(IpAddress)
Country=IPresponse.country.name
City=IPresponse.city.name
if len(suggestionString)>0:
suggestRecord = suggestion(suggestionString,Country,City,IpAddress)
db.session.add(suggestRecord)
db.session.commit()
except Exception,e:return str(e)
return redirect("http://site/thankyou")
@app.teardown_appcontext
def shutdown_session(response_or_exc):
try:
if response_or_exc is None:
db.session.commit()
finally:
db.session.remove()
return response_or_exc
这里是我的配置：
# -*- coding: utf-8 -*-
#NOTE:Replace bands with DB name
DEBUG = False
SECRET_KEY='key'
SQLALCHEMY_DATABASE_URI='mysql://user:[email protected]/sugeestion?charset=utf8'
的问题是，当主持人通过点击按钮来更改建议状态页面重新加载但状态不会改变几秒后我刷新然后建议状态将被改变
更新 - 2 2016年5月： 我检查了日志，我发现2个错误发生有关DB
OperationalError: (_mysql_exceptions.OperationalError) (2006, 'MySQL server has gone away') [SQL: u'SELECT `User`.id AS `User_id`, `User`.`Username` AS `User_Username`, `User`.`Password` AS `User_Password`, `User`.`Permission` AS `User_Permission` \\nFROM `User` \\nWHERE `User`.id = %s'] [parameters: (1,)], referer: http://TheWebSite
和
