For paginating a common array I got this solution,

@arr_name = Kaminari.paginate_array(@arr_name).page(params[:page]).per(PER_PAGE_RECORDS)

PER_PAGE_RECORDS is a variable with value as per needed for pagination.

Any better Ideas??

Also to have an ajax call for using pagination one can use this,

In your view,

give id to your div tab 

div id="paginate"

and inside it

<%= paginate @arr_name, :remote => true %>

And in js response file put,

$('#paginate').html('<%= escape_javascript(paginate(@arr_name, :remote => true).to_s) %>');

So your requests will be AJAX.

Thanks.

This is the only available helper method to paginate an array object using Kaminari. Another alternative is, as suggested solution in kaminari wiki page, add the instance methods to the array object.

If you are trying a common solution based on the ActiveModel return type ( .all returns array and .where returns ARL) then following is an workaround.

unless @arr_name.kind_of?(Array)
  @arr_name = @arr_name.page(params[:page]).per(PER_PAGE_RECORDS)
else
  @arr_name = Kaminari.paginate_array(@arr_name).page(params[:page]).per(PER_PAGE_RECORDS)
end
