Rails - May 2007 - hi, how can i rewrite this to take out commas in tag field?

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('',
'')
