chore(dao): Condense delete/bulk-delete operations #24466

john-bodley · 2023-06-20T21:26:49Z

SUMMARY

Per SIP-92 Proposal for restructuring the Python code base #24331 organized all the DAOs to be housed within a shared folder—the result of which highlighted numerous inconsistencies, repetition, and inefficiencies.

This PR (one of many smaller bitesized PRs) condenses the single (delete) and bulk deletion (bulk_delete) logic into a single (delete) method which removes a bunch of copypasta and helps to standardize the code.

This logic is temporary. It should be cleaned up when we refactor the commands and enforce that validate doesn't augment any properties.

This is more accurate, i.e., the DatasetColumnDAO rather than the DatasetDAO should be deleting the column.

items seems to be a more accurate/consistent than models, i.e., we're deleting database items/instances as opposed to models.

The bulk_deletion logic differs from the delete logic in the sense that the former first deletes the relationships (which in actuality may not be explicitly required) before deleting the dataset, whereas the later only deletes the datasets (which in theory should delete all the records with an explicit relationship).
