I am not sure why this is wrong

Please tell me what is wrong in my solution. I tested this in rubymine and it shows the grocery_list hash properly. I need to move forward but until I finish this I cannot, so please help me with the solution here.

shopping_list.rb 
grocery_list = { 'title' => 'Grocery List', 'items' => [] }
grocery_item = { 'title' => 'Bread', 'quantity' => 1 }
for i in grocery_item.each_key{|key|}
  grocery_list['items'].push(i)
end

Try:

grocery_list['items'].push(grocery_item)

Thanks that worked. I guess I was over analyzing the question. It was just as simple as your solution or using <<. They are asking how can you add elements to an array.

You can also just do: 

grocery_item.each_key do |key|
  grocery_list['items'].push(grocery_item)
end

I don't think for loops are really used in Ruby all that much.
