Monkey Patching
---------------

After migrating the models and loading the initial data through fixtures, you can monkey patch (*if you're into it*) **django-ph-geography** models using the provided methods to suit your needs:


Adding new fields
^^^^^^^^^^^^^^^^^

You can use the custom method ``add_field`` provided by abstract model class ``ph_geography.models.PhilippineGeography`` to add fields to the models provided.
Using the said method to the abstract model will apply the action to all subclasses.

Example:

.. code-block:: python

    from django.db import models

    from ph_geography.models import PhilippineGeography
    from ph_geography.models import Region


    # Add field to Region, Province, Municipality, Barangay, and any subclass models of PhilippineGeography
    PhilippineGeography.add_field('all_models', models.BooleanField(null=True))

    # Add field 'single_model' to Region
    Region.add_field('single_model', models.BooleanField(null=True))


Removing existing fields
^^^^^^^^^^^^^^^^^^^^^^^^

You can use the custom method ``remove_field`` provided by abstract model class ``ph_geography.models.PhilippineGeography`` to remove fields to the models provided.
Using the same method to the abstract model will apply the action to all subclasses.

Example:

.. code-block:: python

    from ph_geography.models import PhilippineGeography
    from ph_geography.models import Municipality
    from ph_geography.models import Region


    # Remove field to Region, Province, Municipality, Barangay, and any subclass models of PhilippineGeography
    PhilippineGeography.remove_field('population')

    # Remove field 'island_group' from Region
    Region.remove_field('island_group')

    # Multiple fields to remove are supported
    Municipality.remove_field('is_city', 'is_capital')
