I am trying to use will_paginate with group_by but i keep getting "undefined method `total_pages' for".

--Controller--

@records = Record.paginate( :conditions => ['this_id = ? and that_id = ?',session[:this_id],session[:that_id]], :page => params[:page],:order => 'created_at DESC', :per_page => 2).group_by { |c| c.created_at.to_date }

--view--

<% @records.each do |d, records| %> <b><%= d %></b>   <% for r in records %>     <p><%= link_to r.title, :action => "action", :id => r.id %></p>   <% end %> <% end %> <%= will_paginate @records %>

any help is greatly appreciated.

Silly me!

Here is how I should have written it.

1. Remove the group_by from controller 2. Place it in view

--Controller--

@records = Record.paginate( :conditions => ['this_id = ? and that_id = ?',session[:this_id],session[:that_id]], :page => params[:page],:order => 'created_at DESC', :per_page => 2)

--view--

<% @records.group_by { |c| c.created_at.to_date }.each do |d, records| %> <b><%= d %></b>   <% for r in records %>     <p><%= link_to r.title, :action => "action", :id => r.id %></p>   <% end %> <% end %> <%= will_paginate @records %>
