如何将文件保存到django模型的filefield，以便django处理upload_to的事情？

from django.db import models

class MyModel(models.Model):
    file = models.FileField(upload_to='uploads/')

from django.shortcuts import render

def upload_file(request):
    if request.method == 'POST':
        uploaded_file = request.FILES['file']
        file_path = 'uploads/' + uploaded_file.name

        with open(file_path, 'wb+') as destination:
            for chunk in uploaded_file.chunks():
                destination.write(chunk)

        # 将文件路径或文件对象分配给模型实例的FileField字段
        my_model = MyModel.objects.create(file=file_path)

        return render(request, 'success.html')
    return render(request, 'upload.html')

<form method="post" action="{% url 'upload' %}" enctype="multipart/form-data">
    {% csrf_token %}
    <input type="file" name="file">
    <button type="submit">Upload</button>
</form>
