Instance Method Details

#sequels(steps = nil) ⇒ Object

‘Pagy` instance method used by the `pagy*_nav_js` helpers. It returns the sequels of width/series generated from the :steps hash Example: >> pagy = Pagy.new(count:1000, page: 20, steps: => [1,2,2,1], 350 => [2,3,3,2], 550 => [3,4,4,3]) >> pagy.sequels #=> { “0” => [1, :gap, 18, 19, “20”, 21, 22, :gap, 50],

"350" => [1, 2, :gap, 17, 18, 19, "20", 21, 22, 23, :gap, 49, 50],
"550" => [1, 2, 3, :gap, 16, 17, 18, 19, "20", 21, 22, 23, 24, :gap, 48, 49, 50] }

Notice: if :steps is false it will use the single => @vars size
