Trying to create a UserController route where if I create a user it will create empty children tables linked to that user

Is there a way create another Model from inside the route handler of a specific model?

I think I’m most of the way there. Tell me if I’m on the right track as I know you can probably return a tuple of models Future<(User, UserDetails, MatchMakingData)>

and when I save use I can probably access the user.id once it’s done saving by:

let savedUser = try user.save(on: request).flatMap(to: User.self) { user in … }

While inside the closure I can’t seem to figure out how to create a UserDetails, or MatchMaking Model to assign the newly created user.id to it immediately.

@yungdai have a look at the current WebsiteController for the book:

github.com

raywenderlich/vapor-til/blob/main/Sources/App/Controllers/WebsiteController.swift#L98


      
              }
            }
          }
          
          
func allUsersHandler(_ req: Request) -> EventLoopFuture<View> {
            User.query(on: req.db).all().flatMap { users in
              let context = AllUsersContext(
                title: "All Users",
                users: users)
              return req.view.render("allUsers", context)
            }
          }
          
          
func allCategoriesHandler(_ req: Request) -> EventLoopFuture<View> {
            Category.query(on: req.db).all().flatMap { categories in
              let context = AllCategoriesContext(categories: categories)
              return req.view.render("allCategories", context)
            }
          }
          
          
func categoryHandler(_ req: Request) -> EventLoopFuture<View> {

That shows you how to create models when others are created. Just a note, you should only really do this with web clients - with REST these should probably be separate requests

Thank you for the excellent hint, however I believe that’s for chapter 14 of your book which isn’t done yet. I’ll be anxiously waiting for those releases

It’s actually Chapter 16 but yes!

Thanks for your help though! I was able to create my leaf pages for the API to to create those tables based on your code. It was very helpful.
