Project: Creating Session in Browser

A Rails webapp that uses cookies to maintain a session with clients' browsers.

---

❗ Objectives

This web-app must accomplish the following:

• Use the PostgreSQL database which stores the email and password of visitors.
• Only valid email formats are allowed and it should be unique.
• Use the BCrypt gem to store a secure hash password and it should be at least 6 to 36 characters long.
• Show validation error messages (if any) to signing in visitors.
• Create a session using CookieStore as soon as visitors sign up.
• Show different homepage content for signed-in and non-signed-in visitors.
• If a visitor logs in with an email that doesn't exist in the database, redirect them to the signup page.
• If a visitor signs up with an email that exists in our database then redirect them to the sign-in page.
• Show appropriate flash messages wherever necessary like new sign up, sign in, logout, etc.
• Show visitor sign-up count for both logged out and logged in visitors.
• Redirect logged-in visitor to the homepage if he tries to visit the log-in or signup page.
• Build a responsive site using bootstrap.
• Show logged-in visitors different ways of destroying the session.
• When a visitor manually enters a URL that doesn't exist, redirect them to the homepage with a flash message informing them that the URL doesn't exist.
