Store all the values in a new array


#1

Hi,

the array below is the output from a find(:all)

[#<Boekingen affnr: “vl999”, pnr: “MA5OSG”, agent: “monties”,
ticket_prijs: #BigDecimal:b775f4c4,‘0.138E3’,4(12), aantal_pers: 2,
ticket_fees: nil, res_kosten: nil, commissie: nil, ticket_verz: nil,
tax: nil, total_prijs: #BigDecimal:b775f230,‘0.36316E3’,8(12), bet_id:
nil, vertrek_id: “AMS”, bestemming_id: “MAD”, airline_id: “HV”,
cabinclass: nil, type: nil, eligibility: nil, supplier: nil, heen_datum:
1020204000, terug_datum: 1049061600, outbound_v: nil, outbound_a: nil,
outbound_vluchtnrs: nil, inbound_v: nil, inbound_a: nil,
inbound_vluchtnrs: nil, reis_verz: #BigDecimal:b775ed08,‘0.0’,4(8),
annu_verz: #BigDecimal:b775eccc,‘0.0’,4(8), boeking_status: nil,
enquete_status: 1, holiday_status: 0, eurenq_status: 9, nieuwsbrief: 99,
reference: nil, kadoboncode: nil, boeking_tijdcode: 1030624003,
servicemail_status: nil, factory_master_id: 1>,] ectect

Now i want to store all the values of the “ticket_fees” in a new array.

like this…

ticket_fee = [“2”, “3”, “1”]

How can i do this(newbie)

Thanks…remco


#2

values = ary.collect {|elem| elem.ticket_fees }

In Rails and newer Ruby environments, you can also do this:

values = ary.collect( &:ticket_fees )

But be careful with the latter form (known as “symbol to proc”). In Ruby
1.8
it’s much slower than using a regular block.
