Landing page generator

This platform must create landing pages on demand, that allow visitors to buy from them. Each landing page has a custom link, and combines a product with a salesperson. When a product is purchased, an email with a code for the product is sent to the buyer. I need you to build a site that contains: - Models: salespeople, products, landing pages, landing page templates, codes by product, sales, images. - Payment methods: Paypal, Stripe. - Authentication (gem Devise). - Prefab templates (you just need to make a sample one that returns the required values in plain text and can process a payment, paying as much as the buyer decides -I will care for the design of the final templates). Features: - Admins input salespersons and products into the database. - Admins use the landing page table to relate a salesperson, a product and a landing page template. - Landing pages are then created with a custom slug ([login to view URL]). - Whenever someone buys from a custom website, the payment is processed and stored in "sales", matching: salesperson, product, purchase date, purchase code. - The system takes a product code, marks it as used and sends it to the buyer trough email. Remember: - Features must be a scaffold if possible. - PLEASE: do not use any gem that doesn't come with Rails if I don't approve it first. - Product attributes: name, description, provider name, provider website, product website, minimum price, video link, main image, background image, recommended age, publication date, genre, score1, score2, score3.
