def blank?
  @table.blank?
end

#filter_map(&block) ⇒ Enumerator, Array

Maps over OpenStruct entries and returns an array without nil values

Returns:

  • (Enumerator, Array) —

    Returns a new array, or enumerator if block is nil

def filter_map(&block)
  return enum_for(:filter_map) unless block

  map(&block).compact
end

#join_map(join_with = "") {|Object| ... } ⇒ String

Combines filter_map and join operations

Examples:

object = OpenStruct.new(a: 1, b: nil, c: 3)
object.join_map(" ") { |k, v| "#{k}-#{v}" if v }
# => "a-1 c-3"
object = OpenStruct.new(a: 1, b: nil, c: 3)
object.join_map(", ")
# => "a, 1, b, c, 3"

Parameters:

  • join_with (String) (defaults to: "") —

    The delimiter to join elements with (defaults to empty string)

Yields:

  • (Object) —

    Block that filters and transforms hash elements

Returns:

  • (String) —

    Joined string of filtered and transformed elements
