Hi  
I have there arrays i get like below in controller  
@hardware\_cis=HardwareCi.find\_where(:all)  
@software\_cis=SoftwareCi.find\_where(:all)  
@document\_cis= documentCi.find\_where(:all)  
The above I have to rearrange to get the pagination  
The above as a whole i have to paginate .For example @hardware\_cis  
may contain some 10 items @software\_cis may contain 6 items and the  
other some 12 items…And i have to paginate total 15 items per page like  
5 from each…And in the view I am iterating through each three like

## \<% for document\_ci in @document\_cis %\> code—

## \<% for software\_ci in @software\_cis %\> code–

## \<% for hardware\_ci in @hardware\_cis %\>

I treid like  
@hardware\_cis=HardwareCi.paginate  
per\_page=\>5,:page=\>params[:hardware\_page]  
@software\_cis=SoftwareCi.paginate  
per\_page=\>5,:page=\>params[:software\_page]  
@document\_cis=DocumentCi.paginate  
per\_page=\>5,:page=\>params[:document\_page]

But this is not the way I think .Here i have three seperate pagination  
in view.That is not i want.How can I solve this?Please help

Thanks in advance
