In this lesson, we'll learn how we can specify types for our Lucid Models easily using DTOs we'll generate directly from our models.

until this part i was amazed how flawlessly AdonisJS works with InertiaJS, but this DTO part for me makes it a little bit non-DRY, I understand the generator package that we installed but still.

I agree, it does make things less DRY, but to my knowledge, in other Inertia-supported environments, you would need to define the type specifically for the frontend as well. At least with AdonisJS, we can convert it to the DTO on the server side to ensure what we're passing matches expectations on the frontend.
It would be awesome if we could directly access a serialized type of the model, but that would take quite the doing!

By the way thank you for these videos you have great teaching skills. Is it against TS best practices if I create a types/models.d.ts file inside inertia folder and declare my models as global interfaces/types? This way I don't have to import them inside my vue files, just use them.

That means a lot, thank you, tibormarias! Also, thank you for watching & being an Adocasts Plus member, it's greatly appreciated! Yeah, if you'd rather not use DTOs, I think that's a perfectly viable alternative approach.

Hi Tom, tried using your package to generate dtos, but it gives weird names to my dtos files, it take my whoe path, for example : c_users_emilien_documents_dev_sojatask_app_models_board.ts
Am I doing something wrong ?

Hi emilien! Terribly sorry about that! I had missed normalizing the slashes where the model's file name is determined which resulted in the whole file path being used on Windows.
Should be all fixed up in v0.0.7

Sorry to bother you again. Some of my model's columns are not "generated" in the dto, do you have any idea why ? Must be pretty difficult without context, do you want me to open an issue on github ?

Yeah, if you could create an issue that'd be great, thank you! Currently, this package reads the models as plaintext, line-by-line. So, there's room for error based on formatting. I'm hoping to refactor to instead use ts-morph which should fix those oddities up.
