We’re going to need to see at least the Model and the ModelAdmin classes that you have defined for this.

Please do not post images or screenshots of code. Copy/paste the text of your code into your message.

When you post code snippets here, insert them between lines containing only 3 backticks - ```. (Make sure you use the backtick - ` and not the apostrophe - '.) That means you would have one line with the 3 backticks, your code, and then one more line with just the 3 backticks. This allows the forum software to keep your code properly formatted, which is critical with Python.
