I’ve got this:

\<% for tag in @tags -%\>  
\<%= link\_to tag.name, :controller =\> ‘archives’, :action =\> ‘tags’, :id  
=\> tag.safe\_name %\>  
\<% end -%\>

I want to use the .join(", ") trick to stick a comma between the links,  
where should I do this?

Hello Paul,

> \<% for tag in @tags -%\>  
> \<%= link\_to tag.name, :controller =\> ‘archives’, :action =\> ‘tags’, :id  
> =\> tag.safe\_name %\>

\<%= @tags.collect { |tag| link\_to tag.name, :controller =\> ‘archives’,  
:action =\> ‘tags’, :id =\> tag.safe\_name }.join(", ") %\>

Not tested but it should work.

Aha, got it… I used this instead.

\<%= @tags.collect {|tag| link\_to tag.name, :controller =\> ‘archives’,  
:action =\> ‘tags’, :id =\> tag.safe\_name}.join(", ") %\>

lol, thanks… we submitted that at the same time. I should’ve gave my  
brain a few more minutes to cook over before posting here.

Thanks again though!
