Question

我有一个表格，可以按年份和月份对学生进行筛选。如果按年份过滤，此代码可以正常工作，但如果按月份过滤，则此代码将不工作。我该如何解决？它没有显示该月的可用数据。

views.py

class Student(models.Model):
    name = models.CharField(max_length=100)
    email = models.EmailField()
    phone = models.CharField(max_length=15)
    joined_date = models.DateField()

模板

def serachstudent(request):
    q = request.GET["q"]
    if q:
        students = Student.objects.filter(Q(joined_date__year__icontains=q)|Q(joined_date__month__icontains=q))
        return render(request, "students/view_students.html", {'students': students})
    else:
        return redirect('students:view_student')

Answer 1

只需执行

students = Student.objects.filter(Q(joined_date__year=q)|Q(joined_date__month=q))
