使用Ruby查询具有多个值的哈希数组

Question

I have an array of hashes as follows:

array = [{"name"=>"Nish", "age"=>27, "place"=>"xyz"},
         {"name"=>"Hari", "age"=>26, "place"=>"xyz"},
         {"name"=>"Anan", "age"=>28, "place"=>"xyz"}]

I want to select the hashes with age 27 and 26

How to achieve that.

Answer 1

This will do it:

array.select { |user| [26, 27].include?(user['age']) }

The 'select' will choose any elements that match the provided block.

Answer 2

You can make use of between?

array.select{ |a| a['age'].between?(26, 27) }

This will return you only the hash which has age between 26 and 27

Or You can use include? to check for specific age

array.select{ |a| [26, 27].include? a['age'] }
