refactor: Repeated boilerplate code between upload to database forms #16756

exemplary-citizen · 2021-09-21T01:40:50Z

SUMMARY

class CsvToDatabaseForm(DynamicForm):
    # pylint: disable=E0211
    def csv_allowed_dbs() -> List[Database]:  # type: ignore
        csv_enabled_dbs = (
            db.session.query(Database).filter_by(allow_csv_upload=True).all()
        )
        return [
            csv_enabled_db
            for csv_enabled_db in csv_enabled_dbs
            if CsvToDatabaseForm.at_least_one_schema_is_allowed(csv_enabled_db)
        ]

There's unnecessary duplication here between CSV and other forms.

Instead we can abstract this into a class UploadToDatabaseForm(DynamicForm) with all the repeated boilerplate and then extend those into class CsvToDatabaseForm(UploadToDatabaseForm), class ExcelToDatabaseForm(UploadToDatabaseForm) etc.

One question on the db migration (also, this needs a rebase). I think it may be safer to leave the column name in dbs as-is and only change the rest of the codebase so that we can avoid a database migration.

villebro · 2021-09-29T06:24:37Z

superset/migrations/versions/b92d69a6643c_rename_csv_to_file.py

+def upgrade():
+    with op.batch_alter_table("dbs") as batch_op:
+        batch_op.add_column(
+            sa.Column(
+                "allow_file_upload",
+                sa.Boolean(),
+                nullable=False,
+                server_default=expression.true(),
+            )
+        )
+        batch_op.drop_column("allow_csv_upload")


Wouldn't this remove all existing allow_csv_upload values and set the new allow_file_upload to TRUE?

Instead of adding and dropping the columns, I think we can go with this renaming pattern instead:

Suggested change

def upgrade():

with op.batch_alter_table("dbs") as batch_op:

batch_op.add_column(

sa.Column(

"allow_file_upload",

sa.Boolean(),

nullable=False,

server_default=expression.true(),

)

)

batch_op.drop_column("allow_csv_upload")

def upgrade():

with op.batch_alter_table("dbs") as batch_op:

batch_op.alter_column("allow_csv_upload", new_column_name="allow_file_upload")

-class ExcelToDatabaseForm(DynamicForm):
-    # pylint: disable=E0211
-    def excel_allowed_dbs() -> List[Database]:  # type: ignore
-        # TODO: change allow_csv_upload to allow_file_upload


This is a longstanding TODO so I do think we should go ahead with the db migration.

Thanks @exemplary-citizen, sorry for the delay, I'll give this a new review + test as soon as I have some spare time (hoping to do it this week).

villebro

This is great work @exemplary-citizen ! LGTM and tested to work well!

betodealmeida · 2021-10-28T21:41:38Z

This migration is failing on MySQL for me, for some reason:

sqlalchemy.exc.OperationalError: (MySQLdb._exceptions.OperationalError) (3959, "Check constraint 'dbs_chk_9' uses column 'allow_csv_upload', hence column cannot be dropped or renamed.")

Looks like it happens in MySQL 8: sqlalchemy/alembic#699

john-bodley · 2021-10-29T22:19:29Z

@betodealmeida @exemplary-citizen @villebro it seems like there should be an entry in UPDATING.md for this as the DDL operation may require downtime.

john-bodley · 2021-10-29T23:08:18Z

Also @betodealmeida @exemplary-citizen @villebro the current migration is not suffice. The dbs.extra JSON encoded field needs to be updated given that the schemas_allowed_for_csv_upload field was renamed to schemas_allowed_for_file_upload.

exemplary-citizen · 2021-10-29T23:19:15Z

@john-bodley just opened #17294. feel free to assign to me. I'll start working on a fix

john-bodley · 2021-10-29T23:31:19Z

Thanks @exemplary-citizen. I've assigned the issue to you. Feel free to add me as a reviewer and/or ping me in Slack—given that most of my GitHub mentions seem to get lost in the aether.

Another problem with this PR that I missed: it changed a versioned schema (ImportV1DatabaseExtraSchema), breaking import/export.

(Not complaining or assigning blame, just calling it out so we catch these things in the future.)

junlincc · 2021-11-10T23:57:11Z

Sorry for being late the the discussion. @betodealmeida @john-bodley thanks for calling out.
Looks like this PR involves DB migration? We should definitely come up with a guideline for reviewing PRs that requires DB migration as they have higher risk. At least add the risk label while reviewing the PR.
