What's the cleanest or most idiomatic way to remove all of a user's roles for a particular resource?

Question

I can do this. Is there a more idiomatic way or something directly supported by the API?

transaction do
  Organization.find_roles(:any, organization).where(resource_id: organization.id).pluck(:name).each |role_name|
    remove_role(role_name, organization)
  end
  add_role('new_role', organization)
end

Answer 1

If you just want to get rid of all of those roles then this should do it: (basically what remove_role does but without additional filters or callbacks)

roles
  .where(
    resource_type: 'Organization', 
    resource_id: organization.id)
  .delete_all

If you want it to act more like remove_role then this might be a better way to go:

self.class.adapter.remove(
  self,
  Organization
    .find_roles(:any, organization),
  organization)
