我最近在学习 Django。我用 SQLite 数据库创建了一个模型，并用模型创建了视图。所以我需要编辑页面中模型中的所有对象。像这样的东西： 在此处输入图像描述

更新按钮是否只是所有对象的一个​​按钮或每个对象的一个​​按钮都没关系。

这是html页面（edit_info.html）：

<table class="table">
    <thead class="thead-primary">
        <tr>
            <th class="">نام</th>
            <th class="">نام خانوادگی</th>
            <th class="cell100 column2">جنسیت</th>
            <th class="cell100 column3">کد ملی</th>
            <th class="cell100 column4">شماره پرسنلی</th>
            <th class="cell100 column5">تلفن</th>
            <th class="cell100 column6">آدرس</th>
            <th class="cell100 column7">وضعیت تاهل</th>
            <th class="cell100 column8">سن</th>
            <th class="cell100 column9">حقوق دریافتی</th>
            <th class="cell100 column10">ویرایش</th>
        </tr>
    </thead>
    <tbody>
        {% for employee in employees %}
        <tr class="row100 body">
            <form method="POST" class="post-form" action="/update/{{employee.personnel_code}}">
                {% csrf_token %}
                <th class="cell100 column0"><input type="text" name="first_name" id="id_first_name" required
                        maxlength="100" value="{{ employee.first_name }}" /></th>

                <th class="cell100 column1"><input type="text" name="last_name" id="id_last_name" required
                        maxlength="100" value="{{ employee.last_name }}" /></th>
                <th class="cell100 column2">
                    <input {% if employee.gender %} checked {% endif %} type="checkbox" name="gender" id="id_gender" />
                </th>
                <th class="cell100 column3"><input type="number" name="eid" id="id_eid" required maxlength="20"
                        value="{{ employee.eid }}" /></th>
                <th class="cell100 column4"><input type="text" name="personnel_code" id="id_personnel_code" required
                        maxlength="6" value="{{ employee.personnel_code }}" /></th>
                <th class="cell100 column5"><input type="text" name="phone_number" id="id_phone_number" required
                        maxlength="15" value="{{ employee.phone_number }}" /></th>
                <th class="cell100 column6"><input type="text" name="address" id="id_address" required maxlength="1000"
                        value="{{ employee.address }}" /></th>
                <th class="cell100 column7">
                    <input {% if employee.is_married %} checked {% endif %} type="checkbox" name="is_married"
                        id="id_is_married" />
                </th>
                <th class="cell100 column8"><input type="number" name="age" id="id_age" required maxlength="3"
                        value="{{ employee.age }}" /></th>
                <th class="cell100 column9"><input type="number" name="salary" id="id_salary" required maxlength="10"
                        value="{{ employee.salary }}" /></th>
                <th class="cell100 column10"><button type="submit" class="btn btn-success">
                        بروزرسانی
                    </button></th>
            </form>
        </tr>
        {% endfor %}
    </tbody>
</table>

这是更新方法和此编辑页面的视图：

def edit_info(request):
    employees = Employee.objects.all()
    return render(request, "edit_info.html", {'employees': employees})

def update(request, id):
    employee = Employee.objects.get(personnel_code=id)
    form = EmployeeForm(request.POST, instance=employee)
    if form.is_valid():
        form.save()
        return redirect("/main")
    print(form.errors.as_text)
    employees = Employee.objects.all()
    return render(request, 'edit_info.html', {'employees': employees})

最后是网址：

from django.contrib import admin
from django.urls import path
from employee import views

urlpatterns = [
    path('', views.login),
    path('admin/', admin.site.urls),
    path('main', views.main),
    path('home', views.home),
    path('edit_info', views.edit_info),
    path('update/<int:id>', views.update),
]

使用当前代码没有任何反应。请帮忙！
