Show HN: Rust Web Framework

Nice, congratulations. It must feel so surreal launching this!

One of my biggest learnings from doing a bunch of web MVC through Rails over the years is that the framework should heavily discourage business logic in the model layer.

Some suggestions:

- Don't allow "callbacks" (what AR calls them) ie hooks like afterCreate in the data model. I know you don't have these yet in your ORM, but in case those are on the roadmap, my opinion is that they should not be.

- That only really works though if you not strongly encourage a service aka business logic layer. Most of my Rails app tend to have all of these as command aka service objects using a gem (library/package) like Interactor.*

* It's my view that MVC (and therefore Rails otb) is not ideal by itself to write a production-ready app, because of the missing service layer.

Also, curious why existing ORMs or query builders from the community weren't leveraged?

Disclaimer: I haven't written a line of Rust yet (more curious as the days go by). I'm more curious than ever now, thanks to you!

I am curious where this comes from, because my thinking is the absolutely opposite. As much business logic as possible should belong in the model. Services should almost all be specific more complex pieces of code that are triggered from the model. Skinny controller, Fat Model, is the logic of code organization that I find makes code the easiest to debug, organize, and discover. Heavy service use end up with a lot of spaghetti code in my experience.

The other part is that from a pure OOP pov, the model is the base object of what defines the entity. Your "User" should know everything about itself, and should communicate with other entities via messages.

This I agree with. Callbacks cause a lot of weird side effects that makes code really hard to debug.

Also Django signals, Symfony events... makes things extensible but also hard to debug indeed.
