Django4全栈进阶之路22 项目实战（三种方式开发部门管理）：方式三：FBV+ModelForm+get_object_or_404

1、视图

@login_required
def department_list_view(request):
    departments = Department.objects.all()
    return render(request, 'base/depart/department_list.html', {'departments': departments})
    # department = DepartmentsForm()
    # return render(request, 'base/depart/department_list.html', {'department': department})

def department_detail_view(request, pk):
    department = get_object_or_404(Department, pk=pk)
    return render(request, 'base/depart/department_detail.html', {'department': department})

@login_required
def department_create_view(request):
    if request.method == 'POST':
        form = DepartmentsForm(request.POST)
        if form.is_valid():
            department = form.save(commit=False)
            department.created_by = request.user
            department.updated_by = request.user
            department.save()
            # return redirect('department_detail', pk=department.pk)
            return redirect('department_list')
    else:
        form = DepartmentsForm()
    return render(request, 'base/depart/department_create.html', {'form': form})

@login_required
def department_edit_view(request, pk):
    department = get_object_or_404(Department, pk=pk)
    if request.method == 'POST':
        form = DepartmentsForm(request.POST, instance=department)
        if form.is_valid():
            department = form.save(commit=False)
            department.updated_by = request.user
            # return redirect('department_detail', pk=department.pk)
            return redirect('department_list')
    else:
        form = DepartmentsForm(instance=department)
    return render(request, 'base/depart/department_edit.html', {'form': form})

@login_required
def department_delete_View(request, pk):
    department = get_object_or_404(Department, pk=pk)
    if request.method == 'POST':
        department.delete()
        return redirect('department_list')
    return render(request, 'base/depart/department_delete.html', {'department': department})

2、路由

urlpatterns = [
    # FBV模式+ ModelForm
    path('department/', views.department_list_view, name='department_list'),
    path('department/<int:pk>/', views.department_detail_view, name='department_detail'),
    path('department/add/', views.department_create_view, name='department_add'),
    path('department/<int:pk>/update/', views.department_edit_view, name="department_edit"),
    path('depart/delete/<int:pk>/', views.depart_delete_view, name='department_delete'),
]

3、模块

department_list.html

{% extends 'base.html' %}

{% block content %}
    <div style="margin-top: 16px;">
        <a href="{% url 'department_add' %}" class="btn btn-primary mb-3">添加部门</a>
    </div>
    <div class="card mt-3">
    <div class="card-header">部门列表</div>
    <div class="card-body">
    <table class="table table-bordered">
        <thead>
        <tr>
            <th>ID</th>

            <th>父级部门</th>
            <th>显示排序</th>
            <th>负责人</th>
            <th>联系电话</th>
            <th>邮箱</th>
            <th>部门状态</th>
            <th>操作</th>
        </tr>
        </thead>
        <tbody>
        {% for department in departments %}
            <tr>
                <td>{{ department.id }}</td>
                <td>{{ department.name }}</td>

                </td>
            </tr>
        {% empty %}
