Access the current tenant in a handler

Problem

In a multi-tenant app every query must run against the request's tenant pool.

Add the Tenant extractor to your handler. The resolver maps the request host/subdomain to an Org and hands you a tenant-scoped pool via t.pool().

use rustango::extractors::Tenant;

async fn dashboard(t: Tenant) -> Result<Json<Vec<Project>>, RustangoError> {
    // Every query is automatically scoped to this tenant's database.
    let projects = Project::objects().fetch(t.pool()).await?;
    Ok(Json(projects))
}

Storage modes

Database-mode gives each tenant its own DB (any backend); schema-mode shares one Postgres DB via SET search_path. The extractor abstracts both.
