Help with how is Template handler works for rails 2.2.2

Hi, i want to create a custom template handler for an intranet app.

the template handler will be like erb template (maybe inherent from ERB handler), but the final substituted result will be passed to some unix tools for generating the final result.

looking at the source of rails template handlers. i understand that any template handler should inhernt from TemplateHandler and define compile method that will build a string of ruby code to be handed over to rails for evaluation, and finally send the final result of this evaluation to the client.

MY problem is: the final result will be a generated file on the filesystem, and i couldn't figure how to throw send_file in the mix. i looked at prawnto, rjs, builder and fleximage plugins. but all do not generate results on the filesystem (aka do not use send_file).

Josh is the guy who knows the most about the current api. He'll be able to give you an official answer.

However my hunch is that you'll have to manually set the relevant headers for X-Sendfile and render an empty string. If you're not using X-Sendfile maybe you'll need to duplicate the behaviour that we have in streaming.rb.

Given that revisiting the template API is one of yehuda's goals for 3.0, it could also be a good time to start thinking about additions to the API to support this kind of thing.
