Conditional CanCanCan Abilities












0














I have a ClientServer that has many ClientApplications. I want users to only be able to destroy Servers that are associated with them. Every ClientApplication object has an application_owner_email that is matched against the current_user. If the emails match, they should have destroy permission for the associated Server.
In the abilities.rb, I have the following



if user.has_role?(:application_owner)
can :destroy, ClientServer.all.each do |server|
server.client_applications.each do |app|
app.application_owner_email == user.email
end
end


But this isn't working. I have set up similar conditions. For instance, the below condition works fine:



can :destroy, ClientApplication.all.each do |app|
app.application_owner_email == user.email
end


A user can only destroy ClientApplications where they are the application_owner.



Any help on this would be appreciated.

  • Do you mean that user can destroy a server if all applications on that server are owned by them?

Enumerable#each returns object self, you probably want .all? or .any?:



can :destroy, ClientServer do |server|
server.client_applications.all?{|app| app.application_owner_email == user.email }
end


Note that all? returns true for empty array.



Also note that abilities with blocks cannot generate scopes and are usually slower.
