    # A Form with paging toolbar. Allows browsing and editing records one-by-one.
    #
    # == Configuration
    # Besides +Netzke::Form::Base+ config options, accepts:
    # * +scope+ - specifies how the data should be filtered.
    #   When it's a symbol, it's used as a scope name.
    #   When it's a string, it's a SQL statement (passed directly to +ActiveRecord::Relation#where+).
    #   When it's a hash, it's a conditions hash (passed directly to +ActiveRecord::Relation#where+).
    #   When it's an array, it's expanded into an SQL statement with arguments (passed directly to +ActiveRecord::Relation#where+), e.g.:
    #
    #     :scope => ["id > ?", 100])
    #
    #   When it's a Proc, it's passed the model class, and is expected to return an ActiveRecord::Relation, e.g.:
    #
    #     :scope => { |rel| rel.where(:id.gt => 100).order(:created_at) }
    #
    # == ToDo
    # * Update the number of records after form submit
    class PagingForm < Form
      # override
      def record
        @record ||= model_adapter.first
