Condition
=========

``Conditions`` are used to validate the input data based on rules between fields. They ensure that the relationships between multiple fields satisfy specific criteria before further processing.

Overview
--------

Conditions are added using the ``add_condition`` method. They evaluate the combined input data, ensuring that inter-field dependencies and relationships (such as equality, ordering, or presence) meet predefined rules.

Example
-------

.. code-block:: python

    from flask_inputfilter import InputFilter
    from flask_inputfilter.conditions import OneOfCondition
    from flask_inputfilter.filters import StringTrimFilter
    from flask_inputfilter.validators import IsStringValidator

    class TestInputFilter(InputFilter):
        def __init__(self):
            super().__init__()

            self.add(
                'username',
                filters=[StringTrimFilter()],
                validators=[IsStringValidator()]
            )

            self.add(
                'name',
                filters=[StringTrimFilter()],
                validators=[IsStringValidator()]
            )

            self.add_condition(
                OneOfCondition(['id', 'name'])
            )
