Django 1.2 - Pb 在模板中带有表单(WSGIRequest)

Question

我试图在模板上显示表单，但出现了一个奇怪的错误:

Caught AttributeError while rendering: 'WSGIRequest' object has no attribute 'get'

错误在这一行:{% for field in form.visible_fields %}

我的观点:

def view_discussion(request, discussion_id):
 discussion = get_object_or_404(Discussion, id=discussion_id)
 form = BaseMessageForm(request)

 return render(request,'ulule/discussions/view_discussion.html', {
  'discussion':discussion,
  'form':form,
 })

我的表格:

class BaseMessageForm(forms.Form):
 message_content = forms.CharField(widget=forms.HiddenInput())

我的模板:

<form action="" method="post">
{% csrf_token %}
    {% for field in form.visible_fields %}
        <div class="fieldWrapper">
            {% if forloop.first %}
                {% for hidden in form.hidden_fields %}
                {{ hidden }}
                {% endfor %}
            {% endif %}

            {{ field.errors }}
            {{ field.label_tag }}: {{ field }}
        </div>
    {% endfor %}
    <p><input type="submit" value="Send message" /></p>
</form>

非常感谢您的帮助!

如果我没记错的话，您遇到的错误是因为表单初始化程序的签名错误而发生的:它的第一个参数是“data”，在您的情况下，它驻留在 request.POST (而不是请求本身)中，如果您是通过 POST 到达的。

通常带有表单的 View 看起来像这样:

def my_view(request, ...):
    if request.method == 'POST': # The form has been submitted
        form = MyForm(request.POST)
        if form.is_valid():
            # do whatever you want here, save the form, etc
    else:
        form = MyForm()
    return render_to_response('myform.html', ... )
