Example Usage
-------------

To use the extra fields in an extension, see the example below. For more
information and examples, see the :ref:`extensions-hooks-ref` section.

.. code-block:: python

    call = load_extension('http_notify.py')
    if call:
        url = 'http://default.url' # <url for post data>

        # possibly extract the URL from extra fields
        call = load_extension('extra_fields.py')
        if call:
            repo_extra_fields = call(**kwargs)
            # now update if we have extra fields, they have precedence
            # this way users can store any configuration inside the database per
            # repo
            for key, data in repo_extra_fields.items():
                kwargs[key] = data['field_value']

        # an endpoint url data will be sent to, fetched from extra fields
        # if exists, or fallback to default
        kwargs['URL'] = kwargs.pop('webhook_url', None) or url

        # fetch pushed commits, from commit_ids list
        call = load_extension('extract_commits.py')
        extracted_commits = {}
        if call:
            extracted_commits = call(**kwargs)
            # store the commits for the next call chain
        kwargs['COMMITS'] = extracted_commits

        # set additional keys and values to be sent via POST to given URL
        kwargs['caller_type'] = 'rhodecode'
        kwargs['date'] = time.time() # import time before
        call(**kwargs)
