Rails Ruby on Rails → 2.x

I am using ActiveResource to access a RESTfull WebService exposing LDAP[1] resources through the usage of ActiveLdap[2].

LDAP attributes[3] could be multivalued and some of them are often (objectClass or email as an example).

The ActiveLdap object represents this values as an array:

--------8

>> u.find('Baptiste Grenier')

>> u.mail

=> ["plop@plop.org", "toglut@toglut.org"]

--------8

I have contacted[4] the helpful ActiveLdap team in order to change the xml outputed by the to_xml method, and here is an extract of what the to_xml now produces:

--------8

cn=Baptiste Grenier,ou=people,dc=plop,dc=org

plop@plop.org

toglut@toglut.org

hgPerson

inetOrgPerson

--------8

But this does not make things works better with ActiveResource, as when I try to create a ActiveResource object from this resource, I get this error:

--------8

>> u = User.find('50')

ArgumentError: expected an attributes Hash, got "plop@plop.org"

Perhaps if ActiveResource could be aware of a multivalued type (used in the to_xml like the array type) and then create an attribute as an array, it could be possible to handle such a situation.

Thanks for any help,

Baptiste
