数据如何连接到特定用户ID？

I'm new to Django and python. I've done login forms but I need to know. How can I connect the contents of the page with the user. For example: It's a Q&A site. When you logged in, It shows profile page with the questions that user asked before. How the datas are linked to the specific user ID in the model? Can it be done using the User object? If so, could you give me some simple example with the script?I'm new to Django and python. I've done login f
