How to create object array in rails?

Question

I need to know how to create object array in rails and how to add elements in to that.

I'm new to ruby on rails and this could be some sort of silly question but I can't find exact answer for that. So can please give some expert ideas about this

Answer 1

All you need is an array:

objArray = []
# or, if you want to be verbose
objArray = Array.new

To push, push or use <<:

objArray.push 17
>>> [17]

objArray << 4
>>> [17, 4]

You can use any object you like, it doesn't have to be of a particular type.

Answer 2

Since everything is an object in Ruby (including numbers and strings) any array you create is an object array that has no limits on the types of objects it can hold. There are no arrays of integers, or arrays of widgets in Ruby. Arrays are just arrays.

my_array = [24, :a_symbol, 'a string', Object.new, [1,2,3]]

As you can see, an array can contain anything, even another array.
