has_many, through, want to store email in mysql
...ist
@email_pages, @emails = paginate :emails, :per_page => 10,
:conditions => ["email_id is NULL"]
end
And in the list view this (in short - only from colunn):
<% for email in @emails %>
<tr>
<td><%= email.headers.find(:first, :conditions => [''headerkey_id = ?'',
6]).value %></td>
</tr>
<% end %>
This means that for 30 emails, in the case of 3 columns (from, subject,
date), a total of 32 SELECTS have to be done.. That doesn''t look too
efficient :)
What would be the best way to do this ? Should I use a predef...
