我应该在views.py中添加什么内容，以便特定用户可以在投诉管理系统中添加新的投诉

from django.shortcuts import render, redirect
from .forms import ComplaintForm
from .models import Complaint

def add_complaint(request):
    if request.method == 'POST':
        form = ComplaintForm(request.POST)
        if form.is_valid():
            complaint = form.save(commit=False)
            complaint.user = request.user  # 设置投诉关联的用户
            complaint.save()
            return redirect('complaints')  # 重定向到投诉列表页面
    else:
        form = ComplaintForm()
    return render(request, 'add_complaint.html', {'form': form})

from django import forms
from .models import Complaint

class ComplaintForm(forms.ModelForm):
    class Meta:
        model = Complaint
        fields = ['title', 'description', 'category']  # 根据实际需求添加字段

from django.urls import path
from .views import add_complaint

urlpatterns = [
    # 其他URL映射...
    path('add_complaint/', add_complaint, name='add_complaint'),
]
