Keep in mind that Django doesn't contain any magic syntax parsers - it's just Python code. If what you type doesn't make sense as raw Python, it won't work in Django, either. So - does nameChoices have an attribute called Name? No - nameChoices is a list of objects. Each object in the list might have an attribute called name, but that's not the same thing. To get this example to work, you will need to do a list comprehension to convert the list of objects into a list of names: widgets.Select(choices=[obj.Name for obj in nameChoices]) You will also need to keep in mind the time at which that comprehension will be evaluated. Depending on how you define and use your form, you may find that the choices list isn't as dynamic as you would like. This may be due to the queryset getting evaluated at time of definition, rather than at time of use. If it is evaluated at time of definition, it won't get re-evaluated each time you use it, so the choices list won't be updated if names are added or removed from the list. You may find it necessary to define a function that returns the list, and use that function in the 'choices' definition.
