我有一个拥有ManyToManyField of Users的模型:
models.py
class Excuse(models.Model):
students = models.ManyToManyField(User)
reason = models.CharField(max_length=50)
views.py
def excuse_list(request, block_id=None):
queryset = Excuse.objects.all().prefetch_related('students')
context = {
"object_list": queryset,
}
return render(request, "excuses/excuse_list.html", context)
模板(excuse_list.html)
...
{% for excuse in object_list %}
<tr>
<td>{{ excuse.reason }}</td>
<td>
{% for student in excuse.students.all %}
{{student.get_full_name}};
{% endfor %}
</td>
</tr>
{% endfor %}
...
如何按用户字段按字母顺序对用户集(excuse.students.all
)进行排序,例如:user.last_name?
答案 0 :(得分:1)
您只需更改views.py
即可执行此操作:
queryset = Excuse.objects.all().prefetch_related(
Prefetch('students', queryset=User.objects.order_by('lastname')))
记得导入用户模型!

您可以在Excuse模型中创建一个方法,该方法将返回已排序的学生集:
def get_sorted_students(self):
return self.students.all().order_by('last_name')
然后在您的模板中使用excuse.get_sorted_students
代替excuse.students.all
或者,您可以使用自定义模板标记来呈现学生列表。
