Rendering page as XML or JSON?

[Conrad Taylor]

Hi, is there an easy to render a page as XML/JSON instead of HTML?  For example, I would like to send back the collection as XML document.  Thus, I'm looking for something similar to Rails respond_to whereas

def show

@order = Order.find(params[:id])

respond_to do |format| format.html # show.rhtml format.xml { render :xml => @order.to_xml }

format.js { render :json => @order.to_json }

end

end

Thanks in advance,

-Conrad

You can do something like this, replacing sixxString with your own xml
building method for something prettier, and #beXml with whatever param name
you want to kick it off...

self session currentRequest at: #beXml ifPresent: [ : it |
    self session returnResponse:
        (WAResponse new
            contentType: 'text/xml' ;
            contents: someObject sixxString readStream ;
            yourself)]

If you have a json builder, it'd be similar.  If there's a better way, I
don't know it.

If you make your own WACanvas subclass too you can do something like this:

    response := Seaside.WAResponse new.
    response contentType: 'application/atom+xml'.
    response nextPutAll: '<?xml version="1.0" encoding="utf-8"?>'.
    atom := SeasideAtom.AtomCanvas new.
    atom context: html context.
    html context document stream: response stream.
    ... do stuff with our new atom canvas ...
    self session returnResponse: response.

Hi ALL, thanks for the information and I'll really appreciate it.  At this time, I'm looking to convert a Rails application to Seaside.
