Another simple question: per_page in pagination

Rails
1

Hi,

Why can’t I use a variable to specify the :per_page attribute when using
the most basic form of pagination? (if I use a hardcode number, it
runs) What did I do? Thx.

My code:

def list_orders
page_size = 20
…
order_pages, @orders = paginate(:orders, :per_page => page_size)
end

My Errors:

undefined method `>’ for false:FalseClass

RAILS_ROOT: ./script/…/config/…

Could anyone help me clarify this? I finally had some code working such
that I can sort by column headings on paginated pages… But being
unable to specify :per_page in the search box is a bit annoying.

Thanks…
