Instance Method Details

#__page ⇒ Object

A simple getter to retrieve the current page value. If no one set it up through the ‘page(4)` way, then at least it defaults to 1.

def __page
  @_page || 1
end

#__per ⇒ Object

A simple getter to retrieve the limit value. It will default to Model.per_page

Will have stacklevel too deep if we have ‘per(nil)`. Somehow, the `per_page` must be set either at the `Model.per_page`, `Kaminari.config.default_per_page`, or right here where I just throw a 25 value at it.

def __per
  per(klass.per_page || 25) unless limit?
  options[:max]
end

#page(value) ⇒ Object

Calling ‘page` will trigger pagination.
