Rails 5 get enum key via integer value

Question

I have a model that has the follow enum:

class User < ApplicationRecord
    enum user_type: [:api_user, :web_user]
end

When this gets saved into the database, it saves it with the integer value, as expected. I then have a function that accepts the enum like this (in a controller):

do_something_useful(type: User.user_types[:web_user], user: user)

def do_something_useful(options)
    some_enum_value = options[:type]
    user = options[:user]

    # Not a practical example.  Just an example to demonstrate the issue.

    # Should return Hello, User! You are a web_user type.
    # But returns, Hello, User! You are a 1 type.
    'Hello, #{user.name}! You are a #{some_enum_value} type.'
end

The problem I'm encountering is that the options[:type] is passing the integer value. I'd like to get the key value of User.user_type by the integer. Is this possible?

Thanks again.

Solution

Well, did a bit more searching and found this solution:

User.user_types.key(options[:type])

This will return the key.

Is this the easiest way? Or another better solution?

now index method will be deprecated. You should be used the key method. Just updating.

index is deprecated, use .key instead, is the same.
