Flask project EMU Supporting tagline
project EMU is for train ticket_booking , I have done this project with java before, now I change it to python with Flask
Part One : database tables
their are five tables , Admin is for admin to manage the system; user is for user to sign in and register his accounts; Train is for train information, such as train ID, volume,train type,train number; table Ticket is for info of tickets ,such as ticket ID, start Date , end Date, start place , end Place ,price, seat number,train ID; User_booked_ticket is for making user’s booking tickets, such as train ID and ticket ID
part Two : create a project
to install flask if we don’t have.
sudo easy_install virtualenv
cerate and active its environment：
mkdir emu,cd emu,virtualenv env , the use . env/bin/activate to active. and finally , use easy_install Flask to install flask in this ENV.
Part Three : add code.
create file named “emu.py”,
we need these Plug-in:
flask_mail for sending emails;
flask_principal for managing permissions;
flask_uploads for uploading file;
flask_wtf for preventing duplicate submissions of the form(named “CSRF”?) and recaptcha.
