Adding optional query get parameter to route

[kmerz]

Hello,

First of all, thanks for this really awesome framework. I honestly did not expect to have so much fun again writing a web app!

I am a bit stuck right now. I want to add an optional query get parameter to a route and pass it on to the view.

#[debug_handler]
pub async fn new(
    ViewEngine(v): ViewEngine<TeraView>,
    State(ctx): State<AppContext>,
) -> Result<Response> {
    let trip_id = ctx.query_param("trip_id");
    views::flight::create(&v)
}

I would have expected that the AppContext would have this information, but I can't find anything right now.
I could not find anything in the documentation about this. But from my experience, this is not an unusual way of passing something.

Can someone help me to solve this?

I don't see the query parameters struct in your controller. You can follow on this example:

use axum::extract::Query;

#[derive(Deserialize, Debug)]
pub struct ExampleQueryParams {
    pub trip_id: Option<String>,
}

#[debug_handler]
pub async fn test_endpoint(
    ViewEngine(v): ViewEngine<TeraView>,
    State(ctx): State<AppContext>,
    Query(params): Query<ExampleQueryParams>,
) -> Result<Response> {

   let trip_id = params.trip_id
  ...
}

Thanks a lot. That was precisely what I needed.
