embarrassing, thank you for pointing it out.

I've done that so many times! 😆

We don't need this for this PR.

Creating a new saved query would be an API for when the user clicks "save query" in SQL Lab. Currently that flow uses the old API (savedqueryviewapi/api/create), but when we eventually migrate it to the new v1 API this is the endpoint that would be used.

I would suggest moving this out of the PR, and have a separate PR introducing this and the command, so we can move "save query" to this endpoint.

This is also not needed, let's move to a separate PR.

+        "datasets/": ImportV1DatasetSchema(),
+        "saved_query": ImportV1SavedQuerySchema(),


queries/, this maps to the directory inside the ZIP file

by this do you mean changing it to saved_queries or replacing it with queries/ altogether. Furthermore, would I then use ImportV1SavedQuerySchema still?

This is used when validating the schema of all the files inside the ZIP: https://github.com/apache/superset/blob/master/superset/commands/importers/v1/__init__.py#L108-L111

If you open the ZIP file from a saved query export you'll see that saved queries are stored inside the queries/ subdirectory, so we need to use that:

schemas: Dict[str, Schema] = { "datasets/": ImportV1DatasetSchema(), "queries/": ImportV1SavedQuerySchema(),

ok that makes a lot of sense. Thank you.

+            if file_name.startswith("saved_queries/"):


Same here, currently the directory is queries/. (Check the ZIP file with an exported saved query.)

(We can't change it to saved_queries/ unless we bump the version of the importer.)

+    def _import(
+        session: Session, configs: Dict[str, Any], overwrite: bool = False
+    ) -> None:
+        # discover datasets associated with saved queries


Saved queries are not associated with datasets, they're associated with databases only. This is how the exported saved query looks like:

schema: master label: Untitled Query 2 description: test sql: SELECT * FROM covid_dashboard WHERE WHERE FROM HA AVG SUM MAX uuid: 5a8be71f-f59f-4a7c-a7b3-e59394168062 version: 1.0.0 database_uuid: 45812a92-6844-4578-8692-0cc603c3fed0

So you need to scan saved queries, find the associated databases, import them, then import the saved queries. There's no datasets involved here.

def _import( session: Session, configs: Dict[str, Any], overwrite: bool = False ) -> None: # discover databases associated with saved queries dataset_uuids: Set[str] = set() for file_name, config in configs.items(): if file_name.startswith("queries/"): dataset_uuids.add(config["database_uuid"]) # import related databases database_ids: Dict[str, int] = {} for file_name, config in configs.items(): if file_name.startswith("databases/") and config["uuid"] in database_uuids: database = import_database(session, config, overwrite=False) database_ids[str(database.uuid)] = database.id # import saved queries with the correct parent ref for file_name, config in configs.items(): if file_name.startswith("queries/") and config["database_uuid"] in database: # update datasource id, type, and name database = database[config["dataset_uuid"]] config.update( { "datasource_id": database.id, "datasource_name": database.table_name, } ) config["params"].update({"datasource": database.uuid}) import_saved_query(session, config, overwrite=overwrite)

is what I set it to, if I am understanding this correctly. Though I'd like to talk through what this file is doing

betodealmeida · 2021-03-31T19:06:45Z

Don't forget to add unit tests, you can find examples for all the other imports inside tests.

The lint is going to fail here and in a few other places. You can auto format it by running pre-commit run --all-files.

model_name = "saved query"

ok that saves me a lot of heart ache. ty

A fixture runs setup code before a test function, and cleanup code after. There's no fixture called create_saved_queries, so you should remove this.

that makes sense, sort of like a beforeEach afterEach in RTL. Would it be more thorough to add this fixture?

I suspect these will change every time you run the tests, so you might need to remove these tests.

+

+            """
+        )


This test will probably fail because the SQL is formatted differently (there's no line break after "your query,", eg).

Yeah, they do. Was wondering about this actually, should I just not test the sql or is there a comment to disable the line is too long linter?

You can disable to line it too linter, or break the line:

assert saved_query == ( "-- Note: Unless you save your query, " "these tabs will NOT persist if you clear " "our cookies or change browsers.\n\n" ... )

You need to remove metadata.yaml, since here you're testing that a validation message "Missing metadata.yaml" is shown when the file is missing.
