Stored Messages

Store an OpenUI response with form context and strip its framing before sending model history.

After reading this guide, you will know:

  • How to frame a response with context for storage.
  • How to restore form state and prepare model history.

Store content and context

Use Message when your host stores a response and its form state together:

stored = OpenUI::Rails::Message.build(
  content: 'root = TextContent("Ticket received")',
  context: { form: { status: "open" } },
  finished: true
)

parsed = OpenUI::Rails::Message.parse(stored)
parsed.context # => { "form" => { "status" => "open" } }
parsed.finished? # => true

This is the upstream message framing format with ]]>openui: marker lines. It is not an OpenUI Lang parser. The browser renderer accepts framed content; your host restores context as initial_state: when rendering a surface. Treat client-supplied form state as untrusted input.

Prepare model history

Strip framing and context before sending a stored response back to a model:

OpenUI::Rails::Message.strip(stored)
# => 'root = TextContent("Ticket received")'

Framing does not authorize an action or prove that a user confirmed one. Keep authorization in the server action path.
