# Collection selection

{% hint style="success" %}
This is the official documentation of the `forestadmin-agent-django` and `forestadmin-agent-flask` Python agents.
{% endhint %}

You may not want to import all collections from a data source.

This can be achieved by providing a whitelist or a blacklist in the options of the `agent.add_datasource` method.

```python
from flask_sqlalchemy import SQLAlchemy
from forestadmin.datasource_sqlalchemy.datasource import SqlAlchemyDatasource

db = SQLAlchemy()
with app.app_context():
    db.init_app(app)
    agent.add_datasource(SqlAlchemyDatasource(db), {
        "include": ["Book", "Review"],
        # You can also exclude
        "exclude": ["Author", ...]
    })
```
