turbo_stream helper block support - no method capture

[candland]

I'm testing out the Turbo support and found the turbo_stream helper errors when passing a block in an ERB template.

Am I doing something wrong?

• It works if I create the turbo stream HTML without the helper.
• It works if I use the helper without a block.

hello.rb

class Routes::Hello < Bridgetown::Rack::Routes
  route do |r|
    # route: POST /hello/:name
    r.post "hello", String do |name|
      if r.turbo_stream?
        r.respond_with_turbo_stream # Needed if not using the turbo_stream helper in the view
        render("hello", locals: {name: name})
      else
        r.redirect "/hello/#{name}"
      end
    end
  end
end

hello.erb

<% turbo_stream.append "turbo-test" do %>
  <p>Appended</p>
<% end %>

@candland Well, a couple of things. If you're using the render plugin for Roda, that's outside of Bridgetown's way of handling template rendering…Bridgetown's own ERB rendering solution supports capture.

Nonetheless, Roda has a plugin called capture_erb: http://roda.jeremyevans.net/rdoc/files/lib/roda/plugins/capture_erb_rb.html
and we should definitely support that as well. I'll try to get to that shortly.

@jaredcwhite Yea, I'm using the render plugin. Is there a better / recommended way with the SSR stuff?
