[REQ] Allow "extra" derives for Rust models #19193

Closed trombonehero closed 2 weeks ago

trombonehero commented 1 month ago

Is your feature request related to a problem? Please describe.

I have several models that I need to derive traits like yew::Properties or yewdux::Store. Currently, I have to re-add these traits to my models' #[derive(...)] every time I update them with openapi-generator.

Describe the solution you'd like

I'd like to pass additional properties like deriveTraits='Properties,Store' and use='yew::prelude::*',use='yewdux::prelude::*' via the CLI.

Describe alternatives you've considered

I've tried creating wrappers around the OpenAPI models, but that leads to awkward duplication and pass-through logic.

I can add non-derived functionality by writing impl X for ModelName elsewhere in the crate, but there are some traits that really want to be derived rather than hand-written.

Currently I use Git to track which derivations have been deleted by openapi-generator and, each time I regenerate from a new version of the API, undo these deletions.

Additional context

You can't anticipate every possible use case for these models, so adding extension points seems logical to me.

did you try using customized templates (e.g. -t via CLI)?

Hi @wing328, it looks like templates can indeed solve at least part of my issue... thanks!
