Flask-SQLalchemy：'function'对象没有属性'items'

Question

代码：

def get_average(questions):
        i = []
        for question in questions.items:
            if question.correct:
                i.append(question)
        return len(i) * 10

运行时出现错误AttributeError: 'function' object has no attribute 'items'。 questions参数传递给flask-sqlalchemy分页对象viewable here。

这应该是一个列表，并且在运行代码时：

for x in questions.items:
        print(x.correct)

它正常工作并且符合预期。更改导致此错误的内容。这两段代码都使用相同的questions对象。

整个视图功能如下：

students = current_user.students

student_averages = {}

for student in students:
    student_averages[student.username] = (student, [])
    student_avg_list = student_averages[student.username][1]

    questions = student.questions.paginate(page=1, per_page=10)

    for x in questions.items:  # Works
        print(x.question_text)

    def get_average(questions):
        i = []
        for question in questions.items:  # Gives error
            if question.correct:
                i.append(question)
        return len(i) * 10
