Updating the Definitions object

The last step in setting up your dbt project in Dagster is adding the definitions you made (ex. your dbt_resource and dbt_analytics asset) to your code location’s Definitions object.

Modify your root-level __init__.py to:

Load assets from dbt.py file, and
Register the dbt_resource from .resources under the resource key dbt

After making those changes, your root-level __init__.py should look like similar to below:

from dagster import Definitions, load_assets_from_modules

from .assets import trips, metrics, requests, dbt # Import the dbt assets
from .resources import database_resource, dbt_resource # import the dbt resource
# ...other existing imports

# ... existing calls to load_assets_from_modules
dbt_analytics_assets = load_assets_from_modules(modules=[dbt]) # Load the assets from the file

# ... other declarations

defs = Definitions(
    assets=[*trip_assets, *metric_assets, *requests_assets, *dbt_analytics_assets], # Add the dbt assets to your code location
    resources={
        "database": database_resource,
        "dbt": dbt_resource # register your dbt resource with the code location
    },
  # .. other definitions
)
