Continued simplification of Taxonomy model, squashed migrations [FC-0030] #33438

bradenmacdonald · 2023-10-06T18:18:31Z

Description

This is a minor update of the content tagging app to simplify it in correspondence with openedx/openedx-learning#91

It removes the required field which we don't really have a use for, and it makes the language taxonomy to be managed by a migration with auto-created tags, rather than imported one time via a fixture.

Testing instructions

For now there is little ability to manually test, so just make sure the tests are passing.

Deadline

None

Hi @bradenmacdonald!
We need to update openedx-learning in edx-platform to finish the PRs below:

Let me know if you need a hand to make the test pass to unblock this PR!

@rpenido Yes, I know but I'm having some trouble with the tests actually. It seems that the LanguageTaxonomy created by a data migration is not available during the test run, and I can't figure out why.

bradenmacdonald · 2023-10-09T23:04:52Z

@rpenido OK, I figured out the problem actually. Should have this PR unblocked soon.

+        ('content_tagging', '0006_simplify_models'),


We were starting to get problems with some of these migrations, referring to models that have been deleted or depending on migrations which depended on fixtures, which were later changed or deleted (note to self: migrations should never reference fixtures). So I've squashed the migrations here which makes it much simpler and more robust. I'd really like to get the squashed version into Quince. If possible, I'd like to squash the migrations in oel_tagging too but that would be a separate PR.

@rpenido OK, I figured out the problem actually. Should have this PR unblocked soon.

I didn't want to put more pressure than you already had! Happy that you found the issue and also squashed the migrations!

Let us know if you need something!

bradenmacdonald · 2023-10-10T00:01:28Z

@pomegranited @Agrendalath Could you please review this PR? I'd like to get it merged tomorrow so it can make the Quince cutoff and since it's blocking other work; sorry for the short notice. I can ask other reviewers if your plate is full.

I've left 3 recommended changes and one question, but this is good to go once they've been applied.

👍

I tested this:
- Started with the migrations in the master branch (content_tagging.0006_simplify_models, oel_tagging.0010_cleanups)
- Switched to this branch and applied my suggested change (see inline comments).
- Installed the updated openedx-learning==0.2.1
- Applied the migrations and checked the results.
- Rolled back the new data migration: ./manage.py lms migrate content_tagging 0001_squashed
- Re-applied all migrations, and checked the results again.
I read through the code

openedx/core/djangoapps/content_tagging/migrations/0003_system_defined_fixture.py

-    # Adding taxonomy class to the language taxonomy
-    language_taxonomy = Taxonomy.objects.get(id=-1)
-    ContentLanguageTaxonomy = apps.get_model("content_tagging", "ContentLanguageTaxonomy")
-    language_taxonomy.taxonomy_class = ContentLanguageTaxonomy


I'm confused.. The ContentAuthorTaxonomy and ContentOrganizationTaxonomy models have also been deleted, so I would expect them to cause problems just like the ContentLanguageTaxonomy does now? No worries if they're not, I'm just curious.

openedx/core/djangoapps/content_tagging/migrations/0001_squashed.py

+    initial = True
+
+    dependencies = [
+        ("oel_tagging", "0012_language_taxonomy"),


Ach.. I'm afraid this line caused an issue when I was testing openedx/openedx-learning#95 :(

Changing it to this fixes the issue, but means we need to merge/tag openedx/openedx-learning#95 first:

Suggested change

("oel_tagging", "0012_language_taxonomy"),

("oel_tagging", "0001_squashed"),

Here's the steps I took:

Zero-ed the migrations oel_tagging and content_tagging, and ensured all the tables for these apps were dropped.

Checked out edx-platform master (b353019), and installed openedx-learning v0.2.0

Ran migrations, which applied fine:
$ ./manage.py lms migrate Running migrations: Applying oel_tagging.0001_initial... OK Applying oel_tagging.0002_auto_20230718_2026... OK Applying oel_tagging.0003_auto_20230721_1238... OK Applying oel_tagging.0004_auto_20230723_2001... OK Applying oel_tagging.0005_language_taxonomy...Installed 185 object(s) from 1 fixture(s) OK Applying content_tagging.0001_initial... OK Applying content_tagging.0002_system_defined_taxonomies... OK Applying content_tagging.0003_system_defined_fixture... OK Applying content_tagging.0004_system_defined_org... OK Applying content_tagging.0005_auto_20230830_1517... OK Applying content_tagging.0006_simplify_models... OK Applying oel_tagging.0006_alter_objecttag_unique_together... OK Applying oel_tagging.0006_auto_20230802_1631... OK Applying oel_tagging.0007_tag_import_task_log_null_fix... OK Applying oel_tagging.0008_taxonomy_description_not_null... OK Applying oel_tagging.0009_alter_objecttag_object_id... OK Applying oel_tagging.0010_cleanups... OK

Checked out this branch and installed the branch from Squash Tagging Migrations [FC-0030] openedx-learning#95.

Applied migrations, which errored out:
django.db.migrations.exceptions.InconsistentMigrationHistory: Migration content_tagging.0001_squashed is applied before its dependency oel_tagging.0012_language_taxonomy on database 'default'.

Made the above recommended change, and was able to proceed with applying the migrations:
$ ./manage.py lms migrate Running migrations: Applying oel_tagging.0011_remove_required... OK Applying oel_tagging.0012_language_taxonomy... OK Applying content_tagging.0007_system_defined_org_2... OK

Tested rollback, which worked OK¹
$ ./manage.py lms migrate content_tagging zero $ ./manage.py lms migrate oel_tagging zero

Tested applying the squashed migrations, also worked fine:
$ ./manage.py lms migrate Running migrations: Applying oel_tagging.0001_squashed... OK Applying oel_tagging.0012_language_taxonomy... OK Applying content_tagging.0001_squashed... OK Applying content_tagging.0007_system_defined_org_2... OK

¹ I always get errors about the named indexes (content_tag_taxonom_70d60b_idx, content_tag_taxonom_b04dd1_idx, oel_tagging_taxonom_5e948c_idx, etc.) when rolling back migrations ("Cannot drop index 'whatever_idx': needed in a foreign key constraint"). I've seen this before these migrations were squashed, and I don't know why it happens. To get around it, I comment out the AddIndex and AlterUniqueTogether lines in the squashed migrations before rolling back.
