Task #3950

Updated by almost 2 years ago

Create the Tag model.

* name CharField(255)
* manifest ForeignKey(Manifest, related_name='tags', on_delete=CASCADE)
* manifest_list ForeignKey(ManifestList, related_name='tags', on_delete=CASCADE)

unique_together = (name, manifest)
unique_together = (name, manifest_list)

Design assumptions:

Pre-save validation on the model will prevent both manifest and manifest_list from being set.

Tag name uniqueness and referential integrity{1} will be enforced by the plugin. During sync, this happens in the task logic. For content add/remove API calls, this happens in the (docker specific) view. Both can re-use the same code.

*[1]* Tag referential integrity is ensuring that when a manifest or manifest_list is removed from a repository, referencing tags are also removed. Also, when a tag is added to a repository, referenced manifest or manifest_list are also added.
