Django, AJAX The BrickSmasher movie rental chain is being revived so baby boomers can experience the nostalgia of renting movies on VHS tapes. You have been tasked with writing the software store employees will use to manage the rental experience. Pages (templates) Home: "" The home page simply presents a menu of links to the other 3 pages: account creation, manage movies, rent/return movies. Account creation: "account/"

This page displays a form with a post method to enter first name, last name, and email address (which must be unique) and a create account button. The same page displayed on submit, but If the email address is already in the database an error message is displayed; otherwise an account created message is displayed.

The message area is below the form. At the top of the page there is a link back to the home page. Manage movies: "movie/" Displays an alphabetical table of all movies owned by the store, with columns for number of movies in stock and number of movies checked out. There are also (+) and (-) columns which are clickable, allowing the employee to update the database with additional in-stock copies of the movie, or removing movies from stock. In-stock cannot be lowered below 0 (clicking (-) would be ignored.)

Finally, there is an input at the top of the page where a new movie title can be entered, and next to it an "add movie" button. If the title already exists or if it contains only whitespace characters an error message is displayed below the table. Otherwise the list of movies is updated on the page and in the database, with one copy of the new movie in stock. At the top of the page there is a link back to the home page. Rent/return movies: "rent/" An input at the top of the page takes a member's email address, and a submit button.

On submit, if the input contains the email of a member in the database, below the email address are displayed the person's first and last name, along with the table of movies they have checked out. Beneath that is a table of all movies in stock. Clicking on a movie in the checked out table returns it to stock, while clicking on a movie in the all-movies table checks it out for that member.

A member can have no more than 3 movies checked out at a time, and can only check out at most one copy of each movie. Trying to make an invalid check-out results in an error message being displayed below both tables.

At the top of the page there is a link back to the home page. In addition to paths for the 3 pages, you will need 3 paths to handle all the AJAX requests. Manage users: "dbUser/" On get, expects an email. Returns the user object associated with that email, or an error code if it is not found. On post, expects an email, first name, last name.

Create a user in the database with the given info. If that email address already exists, return an error code. Otherwise, return the user object. Manage movies: "dbMovie/" On get, returns an array of all movie objects. On post, expects an action ("new", "add", "remove").

New actions require a movie title. If the title already exists, an error code is returned. Otherwise an array of all movie objects is returned. Add and remove actions expect a movie id. Add increases the copies of that movie in stock by 1. Remove decreases the number of copies in stock.

On success, an array of all movies is returned. On failure (invalid id, remove with no copies in stock) an error code is returned. Manage rentals: "dbRent/" On get, returns an array of all movie checkouts. If a user id is provided, this array is limited only to checkouts for that user. If a movie id is provided the array only has checkout records for the given movie.

If both are provided, the array will have either the one record of that ser checking out the given movie, or it will be empty. On invalid data an error code is returned. On post, expects both user and movie id, as well as an action (rent, return). Creates (rent) or deletes (return) a checkout record.

Returns an array of all movies checked out by thd given user. If data is invalid instead returns an error code. You will need a database table for users, movies, and checkouts, where a checkout is just a foreign key to both a user and a movie.
