Convert Active Record Object into Hash

I have a model Person with fields email, name, age, phone_number. I want to convert Person.all to a hash. The hash should have the structure as follows:

{
"email1" => ["name", "age", "phone_number"],
"email2" => ["name2", "age2", "phone_number2"]
....
}

I tried as_json, map or attributes etc. But it returns array of hashes. How can I create this custom structure?

You can get it from below query,

Hash[Person.all.collect { |user| [user.email, user.attributes.except(:email).values] }]

If you want to omit other attributes like created_at & updated_at, run

Hash[Person.all.collect { |user| [user.email, user.attributes.except(:email, :created_at, :updated_at).values] }]
