检查表单是否存在或在模板中呈现。姜戈

from django.shortcuts import render
from .forms import MyForm

def my_view(request):
    if request.method == 'POST':
        form = MyForm(request.POST)
        if form.is_valid():
            # 处理表单数据
            pass
    else:
        form = MyForm()
    
    return render(request, 'my_template.html', {'form': form})

{% if form %}
    <form method="post">
        {% csrf_token %}
        {{ form.as_p }}
        <button type="submit">提交</button>
    </form>
{% else %}
    表单不存在或无法呈现
{% endif %}
