Link_to action going wrong

Code is from the view. If a user clicks the ‘Over’ link, i want to
update the :groep attribute of the zwemmer to ‘blatest4’. But now, all
the zwemmers :groep are changed when the page loads. How can i fix this?
code:
http://pastie.org/1548696

The following line updates all Zwemmer whose id = zwemmer.id to blatest4

<%= link_to 'Over' , Zwemmer.update(zwemmer.id, :groep => "blatest4")%>

change the link to point to the update action and pass the zwemmer id,
much like along the lines of

<%= link_to 'Over', zwemmer_path(zwemmer, :zwemmer => {:groep => "blatest4"}), :method => :put %>
