Hi Kritika

Ye chanel mein firangi log bhi hai, unko hinglish kaisa samjhenga? 😂

Teko field pe unique constraint lagana padenga

Teko no wapas 1 se start karneke liye query maarana padenga

last_no = Model.objects.filter(categorycode="blah", citycode="blah-blah").count()

unique_code ="LM" + categorycode 
+ citycode + str(last_no + 1)

Aisa code likkha toh result milenga 😋
