Notes

• flaskext had no __init__.py after install on MWS. I had to add one.

• .wsgi expected to contain a from --- import app as application

A guide

Creating a Web App From Scratch Using Python Flask and MySQL

Some problems in this guide

• Import Flask-MySQL with import flaskext.mysql

• Stored procedure in database limited entries to 20 characters! Emails can be longer, and hashed passwords much longer. I increased to 45 characters for the former; 120 characters for latter.

• conn.close() and cursor.close() could happen before declaration. I wrapped in with statements instead. But then we have this issue, that the __enter__() method for connections returns a cursor, so I switched this back.

MWS setup

On MWS I use the following .htaccess

AddHandler wsgi-script .wsgi

Options FollowSymlinks ExecCGI MultiViews Indexes
MultiviewsMatch Handlers

RewriteEngine on
RewriteBase /
RewriteRule ^(signin(/)?)$  /signin/signin.wsgi  [L,QSA]
