Hi all,
Does anyone have any advice about returning multiple values from an
ActionWebService? That is, I''d like to implement something like the
following.
api_method :do_something,
:expects => [{:id => :string}],
:returns => [{:return_code => :int},
{:return_text => :string}]
The easy way to do it would be to wrap everything in a struct:
class ReturnStatus < ActionWebService::Struct
member :return_code, :int
member :return_text, :string
end
api_method :do_something,
:expects => [{:id => :string}],
:returns => [ReturnStatus]
Then I could implement do_something as follows:
def do_something
ReturnStatus.new(:return_code => 0,
:return_text => "Success")
end
But, unfortunately, I''m trying to re-create an existing web service and
don''t have this option. The problem with a struct is that it
translates
into another layer in the XML, and the existing clients won''t know how
to
parse it. Here''s an example of the return code (minus namespaces) if I
use
a struct.
<?xml version="1.0" encoding="UTF-8" ?>
<Envelope>
<Body>
<doSomethingResponse>
<return type="ReturnStatus">
<returnText type="string">Success</returnText>
<returnCode type="int">0</returnCode>
</return>
</doSomethingResponse>
</Body>
</Envelope>
But that <return> object is getting in the way. What I''d like
is:
<?xml version="1.0" encoding="UTF-8" ?>
<Envelope>
<Body>
<doSomethingResponse>
<returnText type="string">Success</returnText>
<returnCode type="int">0</returnCode>
</doSomethingResponse>
</Body>
</Envelope>
I''ve looked a bit at the soap4r files, because if ActionWebService
doesn''t
work, I may have to switch to using that. But even there, I''m having
trouble understanding if I''ll be able to define a mapping that will
keep
this extra layer from being created.
Thanks in advance for your input.
