问题 This is my first project using Laravel (I'm starting with 5.2). I'm building a self managed website. There's an admin that should save site settings for using later in the website. Eg: Background color, social networks, carousel with pictures, products, etc. My first try was creating a model "Setting" with: id | key (unique) | value . When I tried to save social networks (to display in the site header), I realized I'd have to save in "value" a json with URL, title, etc... Ugly implementation
