After many problems and errors I finally deployed my first web app. It just saves the task you enter right now. But it’s a work in progress. Thank you Heroku for providing us free cloud servers. I was stuck on the database problem for a while, as I had to change the format to postsql from sqllite. And also, there was a problem with the script running. Also, to access the heroku servers you need a fast net connection to type commands in bash , and my mtnl sucks.
But in the end, Great Success!
