如何在django中将<textarea>文本发送到python视图？

from django import forms

class MyForm(forms.Form):
    my_textarea = forms.CharField(widget=forms.Textarea)

from django.shortcuts import render

def my_view(request):
    if request.method == 'POST':
        form = MyForm(request.POST)
        if form.is_valid():
            textarea_data = form.cleaned_data['my_textarea']
            # 在这里处理<textarea>文本数据
            # ...
    else:
        form = MyForm()
    
    return render(request, 'my_template.html', {'form': form})

<form method="post">
  {% csrf_token %}
  {{ form.my_textarea }}
  <button type="submit">提交</button>
</form>
