accessible_by submodel

[PHP-Point-Of-Sale]

What exactly happens in this scenario?

@patient.course_enrollments.accessible_by(current_ability)

It seems to do exactly what I want, but it is just crazy that it works

What happens there depends on what you have in the Ability class. In a simple case, CanCan will just append a where clause to that passing in your hash conditions.

# in Ability
can :manage, CourseEnrollment, :enrolled => true

# does this
@patient.course_enrollments.where(:enrolled => true)

It does more complex things when a nested hash is provided because it needs to do a joins clause as well, but the behavior is similar.
