Hi Matt,

First off, thank you so much for releasing Comatose – it seems to be exactly what I need to manage the help pages on rails site I’m building (my first rails project). I ran into two problems pretty early on though, and haven’t been able to make much progress. I posted a message on the rubyforge forum a few days ago, but no one has responded, so I’m not sure if it’s being actively used (though perhaps I’m just unpopular :). I’d really appreciate any thoughts or advice you could give me – even just a point in the right direction.

1) I’ve set the default processor to “erb” and the text filter to “none”. When I add the line <%= image_tag “image.gif” > to a Comatose page, Comatose seems to remove it when the page is rendered. However, <= “test” %> renders fine. Is there something I need to link up specially to access the rails view helpers?

2) It appears that the “clear page cache” link doesn’t clear cached “partials” (where I render the comatose content in a “normal” view). Also, the cache isn’t cleared when I update the page in the comatose admin. Am I missing something obvious? Is there a setting to turn this on? I know I could just disable caching, but if possible I’d like to keep it on for when dealing with this fairly static content.

Hopefully these are things that are obvious to a non-newbie. Thanks again!

Dan

Thanks for the feedback!

1. ERb is enabled in a sort of “sandbox”. None of the Rails helpers are included in the context. However, you can add custom ‘tags’ to the context. A simple example would be:

Comatose::ProcessingContext.define "my_app" do
def img_tag(image_src)
# This is just a 'simplest possible' example:
%Q|<img src="/images/#{image_src}" />|
end
end

Then, in your page, you’d use it like so:

<%= my_app.img_tag('logo.gif')

2. You’re right — that’s a bug. It’ll get fixed in the next version.

Thanks.
