如何在django中将输入从模板发送到视图

<form method="post" action="{% url 'submit_form' %}">
  {% csrf_token %}
  <input type="text" name="username">
  <input type="password" name="password">
  <input type="submit" value="Submit">
</form>

from django.shortcuts import render
from .forms import MyForm

def submit_form(request):
    if request.method == 'POST':
        form = MyForm(request.POST)
        if form.is_valid():
            # 处理有效的表单数据
            username = form.cleaned_data['username']
            password = form.cleaned_data['password']
            # 执行其他操作
            return render(request, 'success.html')
    else:
        form = MyForm()
    return render(request, 'template.html', {'form': form})
