Get element by id from an activerecord hash with rails

Question

I get my hash using this :

@hotels = Hotel.all

it returns : [Hotel1, Hotel2...]

How can i extract from this hash the Hotel id=10 for example?

Thank you for help.

Answer 1

@hotels.select{|h| h.id==10}
#=>[Hotel10]

Answer 2

To find a single element from the Array:

@hotels.find { |h| h.id == 10 }
#=> Hotel10

You might be better off doing Hotel.find(10) instead, though.

Answer 3

Try Array#select

a.select {|hotel| hotel.id == 10}
