I'm sure this is simple but I can't seem to get it:
Works:
@build1 = Booking.build_booking('2009-06-13',3,2,18314)
@build2 = Booking.build_booking('2009-06-13',3,4,18317)
@build = @build1 + @build2
What I want to work...
#for item in @cart.items do
# @build << Booking.build_booking('2009-06-13',3,2,18314)
#end
Doesn't work either...
#(1..3).each do |i|
# @build << Booking.build_booking('2009-06-13',3,2,18314)
#end
I prefer using the wonderful array-methods that ruby has to offer over a for loop:
@build = @cart.items.map { |item| Booking.build_booking('2009-06-13',3,2,18314) }
For the two iterating examples you'd need to set @build prior to calling << on it.
I'm not sure what build_booking is returning but if it's an array (I'm guessing from the first, working, example) then you'd probably want to add the result of build_booking to @build. E.g.
@build = []
for item in @cart.items do
@build += Booking.build_booking('2009-06-13',3,2,18314)
end
@build will need to be an array, or an object that responds to <<, for @build << to work.
When you've done:
@build = @build1 + @build2
What is the value of @build?
The quick approach, though, would be to simply declare the array to combine the two elements:
@build = [ @build1, @build2 ]
I'd use an approach like Magnar, though, which is much more concise.
@build = []
for item in @cart.items do
@build += Booking.build_booking('2009-06-13',3,2,18314)
end
@build.flatten!
flatten will will work even Booking.build_booking is returning an array of bookings
