Pelo que entendi, você está procurando uma maneira de destacar as diferenças no texto para ver as diferenças entre as descrições. A partir daí, sugiro que você limite a função diff a apenas
b_discription pois os outros atributos não parecem estar dentro do escopo do que você precisa. Você espera business_logo , business_name ou mod_date para ser mudado? Independentemente disso, a função a seguir pode ser executada em todos os atributos em seu objeto se eles puderem ser convertidos em uma string. simplediff é um excelente script que encontra a diferença entre duas strings, incluindo:
- Existe em A e não em B (exclusão)
- Existe em B e não em A (Inserção)
