The as_bool Jinja filter will coerce Jinja-compiled output into a boolean value (True or False), or return an error if it cannot be represented as a bool.
In the example below, the as_bool filter is used to coerce a Jinja expression to enable or disable a set of models based on the target.
models:  my_project:    for_export:      enabled: "{{ (target.name == 'prod') | as_bool }}"
