Using custom mime types, I''ve run into instances where I end up
calling the same function over and over again for a specific type.
After a little tweaking I came up with a monkey patch that allows to
pass a default block at mimetype registration time, and allows
responder block calls to take arguments. I uploaded the monkey patch
so let me know your thoughts. It currently only works for ActionPack
1.13.3 but porting to Rails 2 should be easy enough. Here are a couple
usage examples:
Example 1:
Environment:
Mime::Type.register "text/plain", :iphone do |controller|
controller.redirect_to :format => "html" unless
controller.request.env[''HTTP_USER_AGENT''].to_s =~
/Mobile.*Safari/
end
Controller functionality:
respond_to do |format|
format.iphone
end
Example 2:
Environment:
Mime::Type.register "text/plain", :debug do |controller, level,
hash|
level ||= 3
text = case level
...
end
hash.merge({:text => text})
controller.render hash
end
Controller functionality:
respond_to do |format|
format.debug 1, :action => "some_action", :layout =>
"debug"
end
