I got a simple iteration going on

\<% @user.sender.each do |sender| %\>  
…  
\<% end %\>

Can I fetch and display for example only 2 items from my database insted  
of all 4 of them ?

Is there a better way to do this ?  
I could use will\_paginate on the iteration (per\_page =\> 2) but I don`t  
want the links to show up.

limiting the Find method in the controller.

eg:

@user = User.find(:all, :limit =\> 2)

Hope it helps!

Which two are you interested in seeing?

The first two, or two with certain attributes. Is this a space issue or  
a selection issue?

You could create a named scope I think, then refer to

@user.special\_senders.each do |sender|

where the special\_senders scope limits the associated senders to only  
those you want.

Thank you very much, that did the trick.  
It was a selection issue and I think I will use a named scope later on.
