页面页脚中的联系表单 [英] Contactform in footer of page

问题描述

我在网站的页脚中有一个联络表。每一页上都有。它起作用了，但有一个问题：发送后，它就不再显示了。更具体地讲，我想当我的请求不再为空时。

I have a contactform in the footer of a website. So it is on every page. It works, with one problem: as soon as it is sent, it doesn't show anymore. More specific I guess when my request is no longer empty.

@register.inclusion_tag('home/tags/contact.html', takes_context=True)
def contact_form(context):
    request = context['request']

    if request.method == 'POST':
        form = ContactForm(request.POST)
        if form.is_valid():
            subject = form.cleaned_data['naam']
            from_email = form.cleaned_data['email']
            message = form.cleaned_data['bericht']
            messages.success(request, 'Form submission successful')
        try:
            send_mail(subject, message, from_email, ['myemailaddress'])

        except BadHeaderError:
            return HttpResponse('invalid header found')
        return context

    else:
        form = ContactForm()

    return {request: 'context.request', 'form': form}

提示将不胜感激。

推荐答案

它看起来像你每当有人提交表单时，都会重新返回没有表单的模板标签的上下文。

It looks like you are returning the template tag's context without the form whenever someone submits a form.

请参见下文：

• 在函数结束之前不要返回上下文对象，这将使事情更容易处理。


• 最好将键添加到上下文对象，这使您不必重新添加请求，因为它已经存在。



• 将else分支移到最后，即使在收到响应（通过POST）后，您也要一直发送新的（空白）表单。

• Do not return the context object until the end of the function, this will make things simpler to work through.
• Best to add keys to the context object, this saves you from having to re-add request because it is already there.

• Remove the else branch towards the end, you want to send a new (blank) form all the time, even after receiving a response (via POST).

@ register.inclusion_tag（'home / tags / contact.html'，take_context = True）
def contact_form（context）：
request = context ['request']

@register.inclusion_tag('home/tags/contact.html', takes_context=True) def contact_form(context): request = context['request']

if request.method == 'POST':
    form = ContactForm(request.POST)
    if form.is_valid():
        subject = form.cleaned_data['naam']
        from_email = form.cleaned_data['email']
        message = form.cleaned_data['bericht']
        messages.success(request, 'Form submission successful')
    try:
        send_mail(subject, message, from_email, ['myemailaddress'])

    except BadHeaderError:
        return HttpResponse('invalid header found')
    #return context # returning here sends back the context without 'form'

# remove the else branch, you always want to return an empty form
#else:
form = ContactForm()

# return {request: 'context.request', 'form': form}
# return at a consistent place in a consistent way
# add to context, rather then recreating it
context['form'] = form
return context

另一种解决方法是将重定向到联系人页面的URL处于开启状态（但是，您将丢失消息）。

Another workaround would be just to do a redirect back to the URL that the contact page is on (however, you will loose your messages).
