.each do iteration question

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.
