Dari apa yang saya kumpulkan, Anda sedang mencari cara untuk menyoroti perbedaan dalam teks untuk melihat perbedaan antara deskripsi. Dari sana, bolehkah saya menyarankan Anda membatasi fungsi diff hanya b_discription karena atribut lain tampaknya tidak berada dalam cakupan yang Anda butuhkan. Apakah Anda mengharapkan business_logo , business_name atau mod_date untuk diganti? Terlepas dari itu, fungsi berikut dapat dijalankan pada semua atribut di objek Anda jika dapat dikonversi menjadi string.
simplediff adalah skrip luar biasa yang menemukan perbedaan antara dua string, termasuk:
- Ada di A dan bukan B (Penghapusan)
- Ada di B dan bukan di A (Penyisipan)
