我想在我的django模型表单中填充数据，但我不确定如何实现？

# models.py
from django.db import models

class MyModel(models.Model):
    name = models.CharField(max_length=100)
    description = models.TextField()

# forms.py
from django import forms
from .models import MyModel

class MyModelForm(forms.ModelForm):
    class Meta:
        model = MyModel
        fields = ['name', 'description']

# views.py
from django.shortcuts import render, redirect
from .forms import MyModelForm

def my_view(request):
    if request.method == 'POST':
        form = MyModelForm(request.POST)
        if form.is_valid():
            form.save()  # 这将保存数据到数据库
            return redirect('success_url')  # 重定向到成功页面
    else:
        form = MyModelForm()  # 创建一个空的表单实例

    return render(request, 'my_template.html', {'form': form})

<!-- my_template.html -->
<form method="post">
    {% csrf_token %}
    {{ form.as_p }}
    <button type="submit">Submit</button>
</form>

if form.is_valid():
    # 表单有效，处理数据
else:
    # 表单无效，打印错误信息
    print(form.errors)

class MyModelForm(forms.ModelForm):
    class Meta:
        model = MyModel
        fields = ['name', 'description']

    def __init__(self, *args, **kwargs):
        super(MyModelForm, self).__init__(*args, **kwargs)
        self.fields['name'].widget.attrs.update({'class': 'special'})
