Overriding cl-json object encoding

Read Original

This technical article explains a problem where the CL-JSON library incorrectly encodes PostgreSQL NULL values (represented as the :null symbol) from Postmodern DAO objects as the string "null". It provides a detailed solution by defining a custom `encode-json` method for specific CLOS classes to ensure proper JSON serialization, demonstrating Common Lisp's extensibility.
