swh.lister.cpan.lister.get_field_value(entry, field_name)[source]#

Splits field_name on ., and use it as path in the nested entry dictionary. If a value does not exist, returns None.

>>> entry = {"_source": {"foo": 1, "bar": {"baz": 2, "qux": [3]}}}
>>> get_field_value(entry, "foo")
>>> get_field_value(entry, "bar")
{'baz': 2, 'qux': [3]}
>>> get_field_value(entry, "bar.baz")
>>> get_field_value(entry, "bar.qux")
