Hi all,
I have an application that produces an RSS feed of blog posts. To do
this, I have a file rss.rxml that contains code like this:
@blogs.each do |blog|
xml.item do
xml.title blog.subject
xml.link blogs_path
xml.description blog.body
xml.guid blogs_path
xml.pubDate blog.created_at
end
end
I want to move this code into a to_rss method on my Blog model, so
that I can simply write:
@blogs.each do |blog|
blog.to_rss
end
The idea here is that it should be really easy to add other items to
my rss feed, like photos or events - my view file can then generate
the feed for a collection of arbitrary objects, as long as the models
all have to_rss methods.
My question is, what do I need to include in the model in order to use
the xml builder? I want to write in blog.rb
def to_rss
xml.item do
xml.title self.subject
xml.link blogs_path
xml.description self.body
xml.guid blogs_path
xml.pubDate self.created_at
end
end
This raises an error like "undefined variable xml". Does anyone know
how to solve this?
Many thanks,
Adam
