Sources expression property mappings

The property mapping should return a value that is expected by the source. Returning None is always accepted and would simply skip the mapping for which None was returned.

Variables

• Arbitrary arguments given by the source (this is documented by the source).
• properties: A Python dictionary containing the result of the previously run property mappings, plus the initial data computed by the source.
• request: The current request. This may be None if there is no contextual request. See (Django documentation)
