Instance Public methods

[]=(column, value)

Columns that aren’t in the indexes are added after the last index. The indexes are replaced rather than modified, since they’re usually shared with other rows. : (String, untyped) -> untyped

# File activemodel/lib/active_model/indexed_row.rb, line 392
def []=(column, value)
  unless index = @indexes[column]
    index = [@row.size, IndexedRow.max_slot(@indexes) + 1].max
    @indexes = ExtendedIndexes.add(@indexes, column, index)
  end

  if index >= @row.size
    @row.concat(IndexedRow.unset_row(index - @row.size + 1))
  end

  @row[index] = value
end
