Hey Dylan, sorry again. My situation is a bit more complex. Let me try clarifying...
I have... obj = apps.get_model(app_label="myApp", model_name="myModel") But I cannot do... obj.setattr() I may be going about this wrong, but my script asks the user to type the name of the model they want to access into the terminal, hence the `obj` line. Then the script asks the user to type in the column name they want to access. So if the user inputs "myColumn", I'd like to be able to do something like `obj.myColumn = "Some value"`. Is this possible, or am I on the wrong track?
