<!-- Greeting -->
Hey @ilsaloving, I'm here to help you with any bugs, questions, or
contributions you have regarding Superset. Let's tackle this together!
<!-- Answer -->
To obtain the YAML schema definition for data sources in Superset 4.0.2
using the CLI, you should use the `export_datasource_schema` command. Here is
the command you need to run:
```sh
superset export_datasource_schema
```
This command will export the datasource YAML schema to stdout. If you want
to include parent back references, you can add the `-b` flag:
```sh
superset export_datasource_schema -b
```
Regarding the `AttributeError` you encountered with the
`legacy-export-datasource-schema` command, it seems to be related to a change
in the `export_schema_to_dict` function in `dict_import_export.py`. The
function was modified to call `Database.export_schema` with the parameters
`recursive=True` and `include_parent_ref=back_references`. This change might
cause an `AttributeError` if the `Database` class does not have an
`export_schema` method.
Here is the relevant code snippet:
```python
def export_schema_to_dict(back_references: bool) -> dict[str, Any]:
"""Exports the supported import/export schema to a dictionary"""
databases = [
Database.export_schema(recursive=True,
include_parent_ref=back_references)
]
data = {}
if databases:
data[DATABASES_KEY] = databases
return data
```
If `Database` does not have an `export_schema` method, attempting to call it
will result in an `AttributeError`

For the `SqlMetric` class, the `class_` attribute is not defined. The
`SqlMetric` class includes attributes such as `id`, `metric_name`,
`verbose_name`, `metric_type`, `description`, `d3format`, `currency`,
`warning_text`, `table_id`, `expression`, and `extra`. It also includes
relationships, methods, and properties to handle various functionalities
related to SQL metrics

To resolve the issue, you may need to ensure that the `Database` class has
the `export_schema` method implemented or adjust the code to handle the absence
of this method.
