def tag\_with tags  
tags.split(" ").each do |tag|  
Tag.find\_or\_create\_by\_name(tag).taggables \<\< self  
end

i have a text field box where the user can create tags. however, if they  
use commas, the comma becomes part of the tag name. how can i prevent  
this from happening.

before i call the tag\_with, do a remove ‘,’?

thanks

tags.gsub!(/’,’,’ '/) will substitute a space for a comma.

Oops. Should be:

tags.gsub!(/‘,’/, ’ ')

I prefer not to create a table just for tags. I just put a ‘tags’ column  
on the table and do this in my view:

@model.tags.split(’,’).compact.collect{|t|  
link\_to(h(t.strip),"/tags/#{CGI::escape(t.strip)}") }.join(’, ')

test it out on a string

“tag,tagging, , #_#@_(_(_!~{}|, tagged”.split(’,’).compact.collect{|t|  
link\_to(h(t.strip),"/tags/#{CGI::escape(t.strip)}") }.join(’, ')
