Hi all,  
I’ve created an extension that use the rails “paginating find” plugin  
“[Welcome cardboardrocket.com - BlueHost.com](http://cardboardrocket.com/pages/paginating_find)” and it work well on  
the controller side.  
But at this point can I create a radius tag that wrap the  
paginating\_links() method exposed from the helper (already activated  
in my extension) that generate automatically the pagination?

Thanks,  
Mariano

The only case where you would want to do that is if you wanted to  
generate the links inside a page (not a regular view). Is that what  
you’re trying to do? If not, just use the helper as-is in your views.

Yes I want generate the links of pagination for my “Bookshelf”  
extension in a radiant page with a custom tag like this  
“\<r:books:paginate /\>” that work like paginating\_links() in a standard  
rails rhtml view.

This is the code of bookshelf\_tags.rb:

module BookshelfTags  
include Radiant::Taggable

tag ‘books’ do |tag|  
tag.expand  
end

tag ‘books:each’ do |tag|  
result = []  
Book.find(:all, :page =\> { :start =\> 1, :current =\> 2, :size =\> 6  
}).each do |book|  
tag.locals.book = book  
result \<\< tag.expand  
end  
result  
end

tag ‘books:each:book’ do |tag|  
book = tag.locals.book  
%{

### #{book.title}

**#{book.sub\_title}**

pub year: #{book.pub\_year} - data form year: #{book.data\_from\_year} - to year: #{book.data\_to\_year}

} end

tag ‘books:paginate’ do |tag|  
book = tag.locals.book  
%{???}  
end

end

And this is the code that I’ve used in my library page:

\<r:books:each\>  
\<r:book /\>  
  
\</r:books:each\>

\<r:books:paginate /\>
