I have a Contacts controller, that I''m using to output contacts when an index is called, but the XML that I will output for each contact varies. I''m not having any success using :proc or :method :method could work, but the string my method returns, escapes the <> characters I''m using trying to "fake" XML mark-up. Basically, each contact has many Kvs, and I only want to :include output some KV (not all) for each contact. I can :include kvs but that will include ALL. I cannot used proc, because there''s no way for proc to "know" which individual contact it''s being run for. Can anyone recommend an easy way around this? --matt --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Not sure what you meant about fake xml mark-up in your comment above. Another way might be to :include an association whose conditions restrict it to those Kvs you are interested in.

Hey Fred,
Thanks for the rapid response.
But when I
format.fxml { render :fxml => @contacts.to_fxml(:methods=>
[:my_action] ) }
and
def my_action()
return self.kvs.to_xml
end
the resulting XML has the < and > symbols escaped out <?xml
version="1.0"
Unless I''m mistaken, but associations are per Object, correct? Not per
instance. the Kvs i''m trying to output vary per instance. Any other
recommendations?

is it possible to get a quick example of how to override .to_xml?, and maybe add a little bit of markup?

The doc''s give an example of entirely overwriting the output. All I really wanna do is append another tag. I''ve tried using various combinations of super, but super is returning a string. Is it possible then, at least to get an example of how to override xml using super, and appending a tag? I''ve been working on this for the past 3 hrs. Any help would be greatly appreciated. --matt On Feb 26, 6:00 pm, Frederick Cheung <frederick.che...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> On 26 Feb 2009, at 10:37, MattFS218 wrote: > > > > > is it possible to get a quick example of how to override .to_xml?, and > > maybe add a little bit of markup? > > THere''s an example in the documentation for to_xml. > > Fred > > > On Feb 26, 5:16 pm, Frederick Cheung <frederick.che...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> > > wrote: > >> On Feb 26, 10:08 am, MattFS218 <mattdf...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote: > > >>> Hey Fred, > > >>> Thanks for the rapid response. > > >>> But when I > > >>> format.fxml { render :fxml => @contacts.to_fxml(:methods=> > >>> [:my_action] ) } > > >>> and > > >>> def my_action() > >>> return self.kvs.to_xml > >>> end > > >>> the resulting XML has the < and > symbols escaped out <?xml > >>> version="1.0" > > >> Oh I get you. > > >>> Unless I''m mistaken, but associations are per Object, correct?
