# hooks.dbt\_ref(...)

`hooks.dbt_ref(`*`adapter_name: str, target_1: str, target_2: Optional[str] = None,`*` ``target_version: Optional[str] = None)`

* Parameters
  * `adapter_name`: the adapter defined in the projects [profile YML](https://docs.runprism.com/v0.2.2/fundamentals/config-files/profile-yml) to execute the query
  * `target_1`: dbt model (or package)
  * `target_2`: dbt model (if `target_1` is a package). Default is None.
  * `target_version`: the versioned model to use. Default is None, in which case the latest version is. See [here](https://docs.getdbt.com/reference/dbt-jinja-functions/ref) for more details.

{% hint style="warning" %}
**Warning:** `hooks.dbt_ref` does NOT materialize your models for you! You'll need to materialize them yourselve (e.g., with `dbt run`) before using Prism's hooks.
{% endhint %}

* Example:

{% tabs %}
{% tab title="Class-based task" %}

```python
import prism.task
import prism.target
import prism.decorators

import pandas as pd

class GetDbtModel(prism.task.PrismTask):
    
    def run(self, tasks, hooks):
        df: pd.DataFrame = hooks.dbt_ref("my_model")
        return df
```

{% endtab %}

{% tab title="Function-based task" %}

```python
from prism.decorators import task

def get_dbt_model(tasks, hooks):
    df: pd.DataFrame = hooks.dbt_ref("my_model")
    return df
```

{% endtab %}
{% endtabs %}
