inserting hash into a specific array location

Question

I'd like to insert a hash into a specific location in an array. I have this:

arr = [
  {:key1=>"one", :key2=>"two", :key3=>"three"},
  {:key1=>"four", :key2=>"five", :key3=>"six"},
  {:key1=>"seven", :key2=>"eight", :key3=>"nine"}
]

and would like to insert this hash into the array

{:key1=>"---", :key2=>"---", :key3=>"---"}

So that the result is

arr = [
  {:key1=>"one", :key2=>"two", :key3=>"three"},
  {:key1=>"---", :key2=>"---", :key3=>"---"},  
  {:key1=>"four", :key2=>"five", :key3=>"six"},
  {:key1=>"seven", :key2=>"eight", :key3=>"nine"}
]

Can anyone help please

What you want to insert is not a hash, nor is it a valid Ruby object. — sawa

You wanted to do an insert, and Ruby Array has an insert method. All you had to do was refer the docs. — user946611

I think you should use the array insert method.

arr.insert(1, {:key1=>"---", :key2=>"---", :key3=>"---"} )

Check out the example here http://www.ruby-doc.org/core-1.9.3/Array.html#method-i-insert
