Rails - Jun 2006 - to_xml depth ...

hello,

The  "render :xml => myFriends.to_xml", return something like:


<people>
  <person>
    <id type="integer">2</id>
    ...
   <person>


But a Person has a "has_many" relationship and they are not in the
xml,
=> so is it possible to change the depth of the marshall process ?
if it not possible, what are the "rails guideline ;-)" ...


thanks

There are many Rails hosts listed on the RoR site.  My question:

I need a host that provides support for both development and  
production rails sites.

Can anyone recommend a US based host that supports development and  
production hosting ?  I want to use Capistrano, however capistrano  
seems to restart Apache when it syncs your dev site with your remote  
server.  I can''t imagine too many hosting companies like that sort of  
thing.

See the :include option.  In 1.1.2, it currently only supports a depth of 1 
association, but a patch I recently submitted and was accepted now allows 
arbitrary depth of :include.

thanks Blair,
it is the good direction but ...
My relation is Person has many infogroup and infogroup has many 
infoattribute
Person--->*Infogroupe---->*Infoattribute

so, aPerson.to_xml :include => [:infogroups] works well now ... but how 
to go one more step deeper ....
because, aPerson.to_xml :include => [:infogroups, :infoattributes ] 
failed !
I saw something interesting  with google;-), like aPerson.to_xml 
:include => [{:infogroups => infoattributes}] does not work

many thanks for help
Arnaud

There''s always rxml.

yes rxml with the builder is also a solution, but it was more for 
curiosity ;-)
thanks

As I said in my previous note, in 1.1.2, it currently only supports a depth of 1
association, so it won''t do what your looking for.  The next release of
Rails
contains a patch that removes this limitation.
