在Django模板中获取字典键值

Question

I have a dictionary created with Counter() in django. I have a list named studentlist. I fill this list with some elements. Then i get the repeating elements number with Counter().

In my view :

    studentlist = []
    for stu in studentslatetoclassthissemester:
        student = str(stu['student__std_no'])
        studentlist.append(student)

    studentsum = Counter(studentlist)

So studentsum is a dictionary as below.

Counter({'0247': 4, '0044': 1, '0050': 1, '0241': 1, '0854': 1, '0245': 1, '0076': 1, '0234': 1})

In the django template i am trying to get specifi key and values as below :

{% for key, value in studentsum.items %}                  
    {{key}} - {{value}}                  
{% endfor %}

But i get below error :

Exception Type: TypeError

Exception Value: 'int' object is not iterable

Answer 1

change this in view

studentsum = Counter(studentlist)

to

studentsum = dict(Counter(studentlist))
