What would be the purpose of this? To suppress the navigator if
there's only one page? To make the current page be a link to itself?
You can do the former with a Mako function like this:
===
## ************ PAGED REGION *******************
<%def name="paged(page, whats, route_name, query_params)">
<%
"""Put a paged section on a webpage, with links to the other pages.
page: A Page object from Christoph Haas' 'paginate' package.
whats: A plural word describing the elements in the page.
route_name: Name of route for URL generation.
query_params: Dict of query params for URL generation.
Your controller action should look for the 'partial' query parameter.
If present, return the paged region indicated by its value rather than
the entire HTML page.
"""
%>
% if page.item_count == 0 or page.first_item is None:
<p class="instructions">No ${whats}
${"found" if page.item_count == 0 else "on this page"}.</p>
<% return %>
% endif
<%def name="navigator()">
<%
params = query_params or {}
prev = max(page.page-1, page.first_page)
next = min(page.page+1, page.last_page)
is_first_page = page.page == page.first_page
is_last_page = page.page == page.last_page
%>
## Put your navigator HTML here
</%def>
<div id="dynamic">
<div>
Displaying ${whats} ${page.first_item}
to ${page.last_item} of ${page.item_count}.
</div>
<div>${navigator()}</div>
<div style="margin: 0.5em 0">
${caller.body()}
</div>
<div>${navigator()}</div>
</div>
</%def>
===
Call it with a <%call> whose body is the paged content. This function
puts a navbar at the top and bottom of the page, and replaces the
entire region with a message if there are no records. You can put an
'if' in the navigator function if you want to do something special if
there's only one page.
