I would like to create url slugs for tags managed by the acts\_as\_taggable\_on gem. For instance instead of urls like <http://myapp.com/tags/5>, I would like to have <http://myapp.com/tags/my-tag> (where 'my tag' is the tag's unique name).

In models that I create myself I usually do this by overriding the model's to\_param method, and creating a "slug" field in the model to save the result of the new to\_param method. I tried doing this with the Tag model of ActsAsTaggableOn, but it is not working.

I can otherwise override things in the tag.rb class of ActsAsTaggableOn as follows:

```
# Overwrite tag class
ActsAsTaggableOn::Tag.class_eval do
  def name
    n = read_attribute(:name).split
    n.each {|word| word.capitalize!}.join(" ")
  end      
end

```

However, if I try to override the to\_param method in that same block with a method definition like:

```
def to_param
  name.parameterize
end

```

Rails still generates and responds to routes with integer IDs rather than the parameterized name. In fact in the console if I try something like

```
ActsAsTaggableOn::Tag.find(1).to_param

```

The integer ID is returned, rather than the result of the overridden to\_param method.

I'd rather not fork the gem and customize it if there is any way I can do it with my own application code. Thanks.
