D'après ce que j'ai compris, vous cherchez un moyen de mettre en évidence les différences dans le texte pour voir les différences entre les descriptions. À partir de là, puis-je suggérer que vous limitiez la fonction diff à b_discription car les autres attributs ne semblent pas être dans le cadre de ce dont vous avez besoin. Attendez-vous business_logo , business_name ou mod_date être changé? Quoi qu'il en soit, la fonction suivante peut être exécutée sur tous les attributs de votre objet s'ils peuvent être convertis en chaîne.
simplediff est un excellent script qui trouve la différence entre deux chaînes, notamment :
- Existe en A et non en B (suppression)
- Existe en B et non en A (Insertion)
