// create GET  blogs/:blog_id/create
// save   POST blogs
// edit   GET  blogs/:blog_id/edit
// read   GET  blogs/:blog_id
// update PUT  blogs/:blog_id
// delete DELETE  blogs/:blog_id
// index  GET  blogs

// 從表路由生成的路由規則分別是：
// create GET  blogs/:blog_id/comments/create
// save   POST blogs/:blog_id/comments
// edit   GET  blogs/:blog_id/comments/:id/edit
// read   GET  blogs/:blog_id/comments/:id
// update PUT  blogs/:blog_id/comments/:id
// delete DELETE  blogs/:blog_id/comments/:id
