 ## Adding badges throught databuilder (and column level badges)
 
 To add badges using databuilder, you can use the [BadgeMetadata](https://github.com/amundsen-io/amundsendatabuilder/blob/master/databuilder/models/badge.py) class and pass in the entity you want to create a badge relationship for. For an example of how this is done search for badge in [TableMetadata](https://github.com/amundsen-io/amundsendatabuilder/blob/master/databuilder/models/table_metadata.py) to see how we add badge nodes and relationships to neo4j.
-In [hive_table_metadata_extractor.py](https://github.com/amundsen-io/amundsendatabuilder/blob/8655338725bf279ea0332e5e6ab0592c8c7459ae/databuilder/extractor/hive_table_metadata_extractor.py#L106) you can see how the partition column is obtained and added to a column so the badge node can be created and related to the correct column.
