@baris thanks 🙏
in which parts making posts.user.postcount return postcount?
I checked the database and found that pid reserve the IP address of that post as well, however posts.ip obviously does not return that string value.
So I assume that there are codes in which determining function .user.postcount to return an integer right? Can anyone tell me that where could I find those codes, So that I can write some similar function to return the IP address？
