Python 如何使用Django在两个视图之间发送大量文本

我需要一个建议，通过Django在两个视图之间传递大量文本。 下面的代码就是我所想的，但第一个代码不起作用，第二个我不知道使用cookies是否更好

<form method="POST"> {% csrf_token %}
    {{ form.post }} <!-- This is a textarea, the user can write as much as he wants -->
    <input type="submit" value="Prepare to send">
</form>

在url.py中

url(r'^new_view/', new_view, {'post':'baam'}, name='new_view'),

这引发了以下例外情况：

Exception Type: NoReverseMatch
Exception Value: Reverse for 'new_view' with arguments '()' and keyword arguments '{'post': u''}' not found. 1 pattern(s) tried: ['new_view/']

根据您的url定义，

new\u视图

url不带任何参数，因此您会得到错误

但在url中传递数据，特别是您提到的大数据，是不好的。Cookie或django会话是更好的选择

要使用django会话，请将视图更新为

def sender(request):
    if form.is_valid():
        cd = form.cleaned_data
        letter = cd['post']
        request.session['post_data'] = letter
        next = reverse('new_view',)
        return HttpResponseRedirect(next)


def new_view(request,):
    post_data = request.session.get('post_data')
    return render(request, 'new_view.html', {'post': post})

谢谢你，罗汉，我就这样试试！

def sender(request):
    if form.is_valid():
        cd = form.cleaned_data
        letter = cd['post']
        request.session['post_data'] = letter
        next = reverse('new_view',)
        return HttpResponseRedirect(next)


def new_view(request,):
    post_data = request.session.get('post_data')
    return render(request, 'new_view.html', {'post': post})
