How to deserialize boolean params.permit value correctly to make sure it's boolean in Rails

There are params to permit:

{"string_value": "value","boolean_value": "true/false","other_value": "blabla"}

I need to convert the boolean_value to Boolean like this ActiveRecord::Type::Boolean.new.deserialize but when I permit params:

ActiveRecord::Type::Boolean.new.deserialize(params.permit(:boolean_value)[:boolean_value])

it doesn't work correctly because the result is always true.How do I pass and permit this param correctly?
