Django模板没有加载或显示

Question

我不知道为什么，但我面临一个奇怪的问题..我的模板不会加载或显示。能帮帮我吗我使用的是Django 1.7版

它在cmd中也显示以下警告：

  

C：\ Users \ Om Computers \ PyDisco \ venv \ ddisco \ signups \ forms.py：5：RemovedInDjango18Warning：创建没有＆＃39;字段的ModelForm＆＃39;属性或＆＃39;排除＆＃39;属性已弃用 - 表单SignUpForm需要更新     class SignUpForm（forms.ModelForm）：

我有一个名为ddisco的应用程序，其中的应用程序称为注册，我的模板存储在模板文件夹中。

Answer 1

您已定义了两次主视图。您需要删除此第二个视图，这样就不会替换第一个视图：

def home(request):  
    context = {}
    template = "base.html"
    return render(request, template, context)

其次，如果您想使用signup.html，则应在呈现模板时包含它：

return render(request, "signup.html", locals())

我已使用render，因为它更简单，如果您真的想要，可以使用render_to_response。

警告只是一个警告，不是错误。它告诉您在升级到Django 1.8之前更新表单类以包含fields。
