Instance Method Details

#count ⇒ Object

overrides WillPaginate’s weird “ignore limit when counting” behavior. I can’t fall back on super in the branch with a limit_value, since that would fall into WillPaginate’s lap, but since there is a limit_value, safe enough to just instantiate and check length

def count
  if limit_value
    to_a.size
  else
    super
  end
end

#per_page(*args) ⇒ Object

overrides Folio::Page’s per_page similar to WillPaginate’s version, but uses correct semantics for per_page(nil) (vs. per_page()).
