Format unmarshallers¶

Based on format keyword, openapi-core can also unmarshal values to specific formats.

Openapi-core comes with a set of built-in format unmarshallers, but it’s also possible to add custom ones.

Here’s an example with the usdate format that converts a value to date object:

  from datetime import datetime

  def unmarshal_usdate(value):
     return datetime.strptime(value, "%m/%d/%y").date

  extra_format_unmarshallers = {
     'usdate': unmarshal_usdate,
  }

  config = Config(
     extra_format_unmarshallers=extra_format_unmarshallers,
  )
  openapi = OpenAPI.from_file_path('openapi.json', config=config)

  result = openapi.unmarshal_response(request, response)
