Question

I'm newbie to grails and I've tried to use the grails pagination Tag found here link text
and when i tried to use it like he says like the this Controller :

 def pageslist = {
 [pages: Page.list(params)]
}

view

 < g:paginate next="Forward" prev="Back" maxsteps="5" controller="story" action="pageslist" total="${story.pages.count()}" />

it gives me nothing at all and the debugger never enter the controller method.. what is the problem and is there any other way for paginating in server side way

Answer 1

You should use as Colin sugested last, ${Page.count()} and import Page into your gsp:

<% import pa.ck.age.Page %>

or you can add another param to the model returned to the view:

def pageslist = {
   [pages: Page.list(params), total: Page.count()]
}

Answer 2

Try:

<g:paginate next="Forward" prev="Back" maxsteps="5" controller="story" 
            action="pageslist" total="${pages.count()}" />

Because you've returned a map [pages: Page.list(params)] as the model from your controller, you will be able to access the variable pages from your view.

Edit:

You need to get the total count of Pages that you want to paginate through. Either use total="${Page.count()} " or add another variable to your model.

see the documentation on the Paginate tag for more.
