Where I did wrong? How can I solve it? What is the mean of this?

There should be more to your error message (Traceback), It can help find out where the problem takes place. If you have that please add it to your code block here on stack as it can help people assist you easier. — Lemon.py

"E:\Project\twitapp\twitapp-core\user\views.py", line 142, in list Can you share this view, related serializer and model? @Kwall — KutayAslan

@KutayAslan I have provide all the code in the link you can see the line number 32 to 41 in views.py file. this is the which is given in traceback — Kwall

@Kwall edit your question and add the code there. Plus the link you provide to show your code does not show your code (it is not even meant to, it is just an online interpreter for python not a code storing service or so). — Abdul Aziz Barkat

according to the type of error, use passes an object that has no __iter__ specific attribute, while the objects you should pass are something like list, set and etc.
