feat: MPTT relations compatibility issue reproduction #551

Closed Eraldo closed 2 weeks ago

Eraldo commented 2 weeks ago

Description

Trying to get an author and then the total count of the children of that author breaks when there are no children present but requested in the query. Error:

"message": "An unknown error occurred."

The PR includes a test test_nexted_children.py, which illustrates the use case and resulting error.

FYI: Disabling the DjangoOptimizerExtension makes the test pass without any issue.

Reviewer's Guide by Sourcery

This pull request introduces an MPTT (Modified Preorder Tree Traversal) relation to the RelayAuthor model to address an issue where querying for an author and their children would break if no children were present. The changes include modifying the RelayAuthor model to inherit from MPTTModel, adding a parent field to establish the tree structure, and updating the AuthorType to include a children connection. A new test file, test_nested_children.py, is added to illustrate the issue and verify the fix.
