Online voting system using Flask and SQLAlchemy

Online voting system:

This is a simple online voting system created using Flask and SQLAlchemy. It allows users to vote for a candidate by clicking on a vote button next to the candidate's name. The Candidate class is a model that represents the candidates in the voting system and it's defined using SQLAlchemy's ORM. The index() function is a route that handles the voting page of the website and it queries the database for all candidates and passes them to the template for rendering. The vote() function is a route that handles voting for a candidate, it gets the candidate's id from the URL, queries the database for the corresponding candidate, increments the candidate's vote count and commits the changes to the database.
