Instance Method Details

#paginate(options = {}) ⇒ Object

This is the main paginating finder.

Special parameters for paginating finders

  • :page – REQUIRED, but defaults to 1 if false or nil

  • :per_page – defaults to CurrentModel.per_page (which is 30 if not overridden)

  • :total_entries – use only if you manually count total entries

  • :count – additional options that are passed on to count

All other options (conditions, order, …) are forwarded to all and count calls.
