Django 使用模板显示用户的组名

对于我网站的工作人员，我将显示所有注册用户的列表，并显示他们的组。它正在工作，只是我得到的是

，而不是用户组

尝试使用group=form.cleaned_data['group_name']，但我遇到以下错误：int（）的文本无效，以10为基数：user.groups.add（group）处的“Viewers”

forms.py：

class RegisterForm(UserCreationForm):
    first_name = forms.CharField(max_length=30, required=False)
    last_name = forms.CharField(max_length=30, required=False)
    Group = [('Viewers', 'Viewers'), ('Editors', 'Editors'), ('Creators', 'Creators'), ('Staff', 'Staff'), ]
    group_name = forms.ChoiceField(choices=Group)
    is_active = forms.BooleanField(initial=True, required=False)

    class Meta:
        model = User
        fields = ('username', 'first_name', 'last_name', 'email', 'password1', 'password2', 'group_name', 'is_active', )

views.py：

@login_required
@group_required('Staff')
def registerView(request):
    if request.method == 'POST':
        form = RegisterForm(request.POST)
        if form.is_valid():
            user = form.save()
            group = Group.objects.get(name=request.POST.get('group_name'))
            user.groups.add(group)
            return redirect('accounts:users')
    else:
        form = RegisterForm()

    return render(request, 'accounts/register.html', {'form': form})


# Display all active users in a table
class UserView(LoginRequiredMixin, GroupRequiredMixin, ListView):
        template_name = 'accounts/display_users.html'
        group_required = ['Staff']
        queryset = User.objects.filter(is_active=True)

显示_users.html：

{% block main %}
<table class="table">
  <thead class="thead-dark">
    <p>
    <tr>
      <th scope="col"># id</th>
      <th scope="col">Username</th>
      <th scope="col">Group</th>
      <th scope="col">Email address</th>
      <th scope="col">First name</th>
      <th scope="col">Last name</th>
    </tr>
  </thead>
{%for instance in object_list%}
     <tbody>
    <tr>
      <td>{{instance.id}}</td>
      <td><a href = "{% url 'accounts:update' instance.id %}">{{instance}}</a></td>
      <td>{{instance.groups.all}}</td>
      <td>{{instance.email}} </td>
      <td>{{instance.first_name}} </td>
      <td>{{instance.last_name}} </td>
    </tr>
  </tbody>
    {% endfor %}
</table>
{% endblock %}

{%block main%}

#身份证
用户名
组
电子邮件地址
名字
姓
{%例如在对象\列表%}
{{instance.id}
{{instance.groups.all}
{{instance.email}
{{instance.first_name}
{{instance.last_name}
{%endfor%}
{%endblock%}

是否有可能使用不同的{{instance.groups.all}}？

此

{{instance.groups.all}

将给出一个查询集

如果您希望各个组使用

 <td>{% for group in instance.groups.all %}{{group}}{% if not forloop.last %},{% endif %}{% endfor %}</td>

{%for instance.groups.all%}{{group}{%if not forloop.last%}，{%endif%}{%endfor%}
