I was advised to use either the :methods option of to_xml or use a block
to add additional tags to the output. What I'm trying to do is add a
permalink tag to each element in a collection, but I can't seem to get
If I use the :methods option of to_xml, I'd need to access an url helper
from a model, and I haven't figured that out yet.
When using either a proc or a block I don't know how to get the current
record from the collection in order to use a url helper. For example:
render :xml => @messages do |options|
Thanks in advance.
