Messenger chat bot for student timetable

With @jo-pouradier, we created a chat bot for Messenger to help students to get their timetable on messenger which is much eassier than a long and fastidious excel file. That's why we created CPE Planning | Facebook. It's a 24/7 chat bot running with Nodejs on our personnal home lab.

The first version was made by @waleedahmad with his Aww-Bot | Github.

Installation

/!\ It is really complicated to install a chat bot on messenger, be ready to spend a lot of time on it. /!
Fist you need a Facebook page connected with messenger to get a personnal token. Then you need to create a server with an https address (you can use ngrok, localtunnel, or a personnal domain). Then run a nodejs server (I first tried with a python flask server... no sucess) where the url /webhook verify your secret token. Finally your chat bot can be used by developpers and admins! For your app to be accessible to anyone, you need to submit it to Facebook for review, with a privacy policy (more in our Legal part).

Usage

The get_started button is the first thing you see when you open the chat bot. It's a simple button that register the user in the database while asking for his promotion, group and major if necessary. For the database, we are using a local sqlite file to store the user's data. And a json file to store the timetable. We are reccording the user's :

• id (chat id from facebook)
• promotion (3A or 4A)
• group (A, B, C or D)
• major (only for 4ETI students) On the website we are using the user's:
• email (cpe)
• first-name
• last-name
• password
• personnal code (send via messenger)

On Messenger we send to the user a message with a button for each day of the week. When the user click on a button, we send him a message with the timetable of the day according to his promotion and major. The group is not taken into account for the moment it is way too complicated because of the pdf file and too many of unplanned format.

On the website, when the user is connected, he can see his timetable and his personnal code.

Database

For the database we are using an sqlite database. This version works for all students. For the MSO we are using a joint table because of the number of MSO (about thirty). /!\ The database is not finished yet, we are still working on it. The database is composed of 3 tables:

• user :
  • id_user
  • promo
  • filliere
  • groupe
  • majeur
• TJ_User_MSO :
  • id_user
  • id_mso
• MSO :
  • id_mso
  • name_mso
• profile:
  • email
  • prenom
  • nom
  • password (stored in sha256 with salt)
  • psid (=id_user from user table)
