Delete tag assignments when deleting a tag that is referenced in an assignment #16039

gtanzillo · 2017-09-25T21:58:13Z

Eg.

Tag to be deleted - /managed/environment/any1
Referenced in assignment by the tag /chargeback_rate/assigned_to/vm/tag/managed/environment/any1.
Which means that a chargeback rate (tagged with the latter) is assigned to any Vm
tagged with environment/any1. Should also be deleted

spec/models/classification_spec.rb

+
+        ent.destroy
+
+        expect(Tag.where(:name => assignment_tag).take).to be_nil


Do we need a test case showing that a similar tag in a different category isn't removed?

For example, "/chargeback_rate/assigned_to/vm/tag/managed/test_category2/test_entry"

The test I added to the AssignmentMixin tests that. Let me know if you think it still needs more. See https://github.com/ManageIQ/manageiq/pull/16039/files#diff-c96ad7d76c6072d9695e81a29f51e8b0R31

Ah, I guess I was more concerned with destroy not deleting things that are "close" but not exactly the same tag.

Ok, I'll add that test. Thanks!

app/models/mixins/assignment_mixin.rb

+  # with a given tag.
+  def self.all_assignments(tag = nil)
+    scope = Tag.where(["name LIKE ?", "%/#{AssignmentMixin::NAMESPACE_SUFFIX}/%"])
+    scope = scope.where(["name LIKE ?", "%#{tag}"]) if tag.present?


I feel like if there's a bug, it would be in the string matching. As long as we have good tests, it looks ok.

app/models/mixins/assignment_mixin.rb

+
+  # This module method was not intended to be mixed into a class. It is used outside
+  # of any class that may mix this in, (Classification) to find the assignments associated
+  # with a given tag.


Wait wat? I don't understand; Why is this not just then a scope on Tag, as that's exactly what it does?

Actually, just to match the current convention that I'm seeing, why isn't it at last just included in the ClassMethods belong to be included on the class? Then it'd match the current .assignments method.

Chris, per your second point, I wanted to do it that way. But, the code in Classification that needs to delete these tags has no way of knowing which classes have included the mixin and would not know which classes on which to call the method.

I didn't consider making it a scope on Tag. I think that would work fine. But, then knowledge of how assignments are using tags would be added to the Tag class and I think it should stay in the mixin.

Ahh I see, I thought that Classification included this mixin.

In that case, you can make your intentions clear and without your comment by doing the following:

def all_assignments(tag = nil) # ... end module_function :all_assignments

This will signal that this method is intended to be called with the mixin itself as the receiver. It will be mixed in to instances of the class, but will be automatically marked as private. (https://ruby-doc.org/core-2.4.2/Module.html#method-i-module_function)

@jrafanie I added that additional test. Please take a look when you can. Thanks.

spec/models/classification_spec.rb

+        Tag.create!(:name => assignment_tag)
+
+        cat.destroy
+


We probably want this just to show that it deletes the correct tag but not the others (on the next two lines)
expect(Tag.exists?(:name => assignment_tag)).to be false

…ssignment Eg. - Tag to be deleted - /managed/environment/any1 - Referenced in assignment by the tag /chargeback_rate/assigned_to/vm/tag/managed/environment/any1. Which means that a chargeback rate (tagged with the latter) is assigned to any Vm tagged with environment/any1. Should also be deleted https://bugzilla.redhat.com/show_bug.cgi?id=1483365
