Hi Ahmy,
I think this is going to be a bad idea. What I'm guessing your trying
to do is override to_s so you can do something like...
<ol>
<%= news_entry.news_tags %>
</ol>
And in that to_s you'd wrap the individual news_tag objects with some
<li> HTML and such. If you really want to do this, you'd need to
monkey-patch the Array class since news_entry.news_tags is an Array.
It would be much better to write a helper so your view code is like...
<%= tag_list(news_entry.news_tags) %>
Then in your news_entry_helper.rb something like this...
def tag_list(tags)
output = "<ol>"
tags.each{|t| output << "<li>#{t}</li>"}
output << "</ol>"
end
Cool?
