Question

I have a problem trying to make a list from a acts_as_taggable_on tag_list
I have tag list array, and I want to list it so im trying this:

<%= proyects.tag_list.each do |tagsx| %>
* <%= tagsx %>  <br>
<% end %>

And I get the list im looking for, but also the whole array again…
When it renders, looks like this..

* AJAX
* Rails
* Heroku
* Prototype
AJAX, Rails, Heroku, Prototype

Any ideas on getting rid of the last line?
Or do you guys know a more efficient way of achieving this?

Thanks in advance.

Change this:

<%= proyects.tag_list.each do |tagsx| %>

to this:

<% proyects.tag_list.each do |tagsx| %>

You don’t want to output the return value of the .each call, just the elements of the array. Calling Array#each with a block returns the array (as you are):

each {|item| block } → ary
each → an_enumerator
Calls block once for each element in self, passing that element as a parameter.
If no block is given, an enumerator is returned instead.

and that’s were the comma delimited list is coming from.
