Where should I store the code when I build "custom file field"?

[imhomer]

I am going through a tutorial book titled "Python Web Development with Django". This tutorial taught me how to create my custom file field, but it did not indicate where should I store the code. Could you please help me?

I figure it out by myself... Just store it in my application file, then I can import it by using "from ProjectName.App Name import FileName"
