What's the community 'most liked' approach to assert on a request, on query or body parameters, the param[:foo] is actually true otherwise you do other thing.

Do you use?

1. if params[:foo]

2. if params[:foo].to_s == "true"

3. if params[:foo].presence?

4. if ActiveModel::Type::Boolean.new.cast(params[:foo])

Just curious on what do you use.
