Built-in Rules
==============

Squabble ships with several rules that are focused mostly on
preventing unsafe schema migrations. To enable these rules,
reference them in your ``.squabblerc`` configuration file.

For example:

.. code-block:: json

  {
    "rules": {
      "AddColumnDisallowConstraints": {
        "disallowed": ["DEFAULT"]
      },
      "RequirePrimaryKey": {}
    }
  }

.. contents:: Available Rules
