Defined in:
lib/weft/redirect.rb

Overview

Value object returned from action callables to trigger navigation instead of re-rendering. The Router detects Redirect returns and sends HX-Redirect (htmx) or 302 (traditional form).

Preferred form accepts a Page subclass:

Weft::Redirect.to(OrderDetailPage, order_id: order.id)

String path fallback:

Weft::Redirect.to("/orders/#{order.id}")

Convenience wrapper:

Weft.redirect(OrderDetailPage, order_id: order.id)
