在django中使用bootstrap设置样式时，我的表单无法保存

from django.shortcuts import render

def my_view(request):
    if request.method == 'POST':
        form = MyForm(request.POST)
        if form.is_valid():
            # 保存表单数据
            form.save()
            return render(request, 'success.html')
    else:
        form = MyForm()
    return render(request, 'my_template.html', {'form': form})

# urls.py
from django.urls import path
from . import views

urlpatterns = [
    path('my_form/', views.my_view, name='my_form'),
]

# my_template.html
<form method="post" action="{% url 'my_form' %}">
    <!-- 表单字段 -->
</form>

<!-- 引入Bootstrap的CDN链接 -->
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0/dist/css/bootstrap.min.css">
<script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0/dist/js/bootstrap.bundle.min.js"></script>

<!-- 或引入本地文件 -->
<link rel="stylesheet" href="{% static 'css/bootstrap.min.css' %}">
<script src="{% static 'js/bootstrap.bundle.min.js' %}"></script>
