Google Summer of Code 2023 Final Report

• Name: Bhuvnesh Sharma
• Organization: Django Software foundation
• Mentors: Mariusz Felisiak and Natalia Bidart
• Project: Moving models between apps.
• Proposal: GSoC 2023 Moving models between apps proposal
• Ticket: #24686
• Forum: here.
• Discussion: PR

Project Goals

• Make auto-detector generate migrations that allow moving a model between apps.
• Write auto-detector tests to check if the operations generated to move a model are correct.
• Write operations test to check if the set of operations generated by auto-detector actually moves a model correctly or not.
• Add release note and document the new feature.

Project Goals Achieved

• Work done

  • Created a new method in auto-detector which detects the moved model and automatically generates the migrations required to move that model to other model.
  • Wrote tests to check if the generated set of migrations by the auto-detector are correct.
  • Wrote test to check if the auto-generated migration operations actually move a model without any errors.
  • Created a demo-project to demonstrate and thoroughly test the working of the newly implemented feature.
  • Added a release note and short note on how moving a model between apps is handled by django.

• Merged PRs

  While Testing the newly added feature, we came across a bug which made AlterField operation remake a table while renaming a related model with db_table. But since only the model name is changed and not table name(db_table), AlterField should be a noop. This was fixed in #17085.

• Work Under Review

  • The new method generate_moved_model() to auto-detect moved model.
  • Tests
  • Documentation All in #16905

I would like to thank my mentor Mariusz Felisiak and Natalia Bidart for helping and guiding me whenever I got stuck. All the reviews were helpful and I learned a lot about the django internals from them.
