python之Django 联系表单类型错误 : context must be a dict rather than Context

我遇到错误“context must be a dict rather than Context”。提交联系表格后。我有一种预感，这是由于与 Django 1.11 的不兼容问题。不太确定如何找到解决方法。

这是我在回溯中得到的:

这是我的 views.py 文件中联系路由的代码片段:

def contact(request): 
form_class = ContactForm 
 
# new logic! 
if request.method == 'POST': 
    form = form_class(data=request.POST) 
 
    if form.is_valid(): 
        contact_name = form.cleaned_data['contact_name'] 
        contact_email = form.cleaned_data['contact_email'] 
        form_content = form.cleaned_data['content'] 
 
        # email the profile with the contact info 
        template = get_template('contact_template.txt') 
 
        context = Context({ 
            'contact_name': contact_name, 
            'contact_email': contact_email, 
            'form_content': form_content, 
        }) 
        content = template.render(context) 
 
        email = EmailMessage( 
            'New contact form submission', 
            content, 
            'Your website <test@gmail.com>', 
            ['youremail@gmail.com'], 
            headers = {'Reply-To': contact_email } 
        ) 
        email.send() 
        return redirect('contact') 
 
return render(request, 'contact.html', { 
    'form': form_class, 
}) 

这显然是导致错误的行:

content = template.render(context) 

不太确定如何解决这个问题，寻求一些指导!谢谢!

请您参考如下方法:

尝试替换

context = Context({ 
    'contact_name': contact_name, 
    'contact_email': contact_email, 
    'form_content': form_content, 
}) 

与

context = { 
    'contact_name': contact_name, 
    'contact_email': contact_email, 
    'form_content': form_content, 
}
