How to assign an element in a hash array with index 0?

Question

Ruby on Rails

I have an array of hashes

hash = [
  {:name=>"Автомобили"},
  {:name=>"Мотоциклы"},
  {:name=>"Квадроциклы"},
  {:name=>"Грузовики"}
]

It is necessary to sort so that if , then put this hash in the first place. those. give it index 0hash[:name] == "Грузовики"

hash = [
  {:name=>"Грузовики"},
  {:name=>"Автомобили"},
  {:name=>"Мотоциклы"},
  {:name=>"Квадроциклы"}  
]

If it's not in the array, then do nothing.

Take it out and put it on top of the stack or create a new list in the correct order or enter the weights and sort by them.
