#draw_column_bitset(rec, col_or_sym, bitset) ⇒ Object

draw bitset column in list.

INPUTS

rec

AR object

col_or_sym

column object returned by rec.class.columns

  turn_on_flags.map{|f| rec.class.human_const_name(bitset, f) }.join(' ')
end

#draw_column_enum(rec, col_or_sym, enum) ⇒ Object

draw enum column in list.

When enum for col is defined, constant string (rather than rec.col value) is drawn. See get_enum() for more detail of enum for the col.

EXAMPLE

Question has status attribute and Question::Status enum. When question.status == 300, draw_column_enum(question, status_col, Question::Status) returns I18n.t(‘WORKING’).

Where:

  • question is Question AR object.

  • status_col is one of Question.columns object for status column.

INPUTS

rec

AR object

col_or_sym

column object returned by rec.class.columns

enum

Module which contains constants

SEE ALSO

get_enum()

get enum definition

draw_enum()

draw enum selection field

draw_column_bitset()

draw bitset column in list

end

#get_bitset(model, col) ⇒ Object

get bitset Module.

When ColBitset(camelized argument col name + ‘Bitset’) module exists, the ColBitset is assumed enum definition.
