Can'；我的Django表格不起作用

我不知道这里发生了什么：我以为我是在实现一个非常简单的Django表单，遵循Django文档中的ContactForm示例（尽管我对forms.py使用了不同的示例）。然而，由于某种原因，当页面加载时，我得到了模板，但没有出现表单。根据模板，所有HTML都在那里，但是Django的东西（我添加的表单和

test

变量）没有呈现

我有点希望在某个我无法识别的地方有一个复杂的地方，但是，我担心我犯了一个n00b错误，我应该能够发现

如果有人能帮我，我将非常感激

我的代码： forms.py:

class ContactSupportForm(forms.Form):
    fields = ('theSubject', 'theMessage')
    widgets = {
        'theMessage': forms.Textarea(attrs={'cols': 55, 'rows': 12}),
        }
    error_css_class = 'error'
    required_css_class = 'required'

from forms import ContactSupportForm

@login_required
def postSupportMessage(theRequest):
"""The new view to which the support form is submitted"""
isLoggedIn = linfiniti.isUserLoggedIn(theRequest)
if isLoggedIn == True:
    myRequestingUser = theRequest.user
    myRequestingUserEmail = myRequestingUser.email
else:
    return HttpResponseForbidden()

    theForm = ContactSupportForm(theRequest.POST)
    if theForm.is_valid():
        theIssueSummary = theForm.cleaned_data['theSubject']
        theMessageDesc = theForm.cleaned_data['theMessage']
        theIssueDesc = '%s \n \n Username: %s \n \n User Email: %s' % \

但是，我仍然没有在模板中获得表单，也没有在模板中获得测试。视图正确地返回模板，但它不返回表单或测试，正如Aamir指出的那样，您还没有在表单上定义任何字段，也不清楚您是从何处获得这样做的想法的。清楚地显示要执行的操作：

class ContactForm(forms.Form):
    subject = forms.CharField(max_length=100)
    message = forms.CharField(widget=forms.Textarea(attrs={'cols': 55, 'rows': 12}))
    error_css_class = 'error'
    required_css_class = 'required'

窗口小部件

和

字段

属性仅在ModelForms的内部元类中使用，ModelForms是从模型生成的表单，当您希望覆盖该模型上字段的默认字段/窗口小部件时。你没有在这里这么做，所以他们没有意义

此外，在您的视图中，您应该删除第二个

else

子句：当出现验证错误时，您将重新实例化表单，这样错误就不会显示在HTML页面上。删除该子句将允许直接执行render_to_响应调用

---

（关于变量名的问题，除了camelCase问题，我无法想象为什么你觉得有必要在一半变量前面加上

the

，而另一半变量前面加上

my

。这是在添加什么信息？

Argh，请停止使用有趣的JavaStyleVariableNames！camelCase有什么不喜欢的？！为我工作！你的班次错了。请再次阅读文档。我不知道你在那里干什么。您的表单中没有定义字段。啊，请使用funnyJavaStyleVariableNames停止！camelCase有什么不喜欢的？！为我工作！你的班次错了。请再次阅读文档。我不知道你在那里干什么。您的表单中没有定义字段。谢谢Daniel-我已经更新了问题-尽管更改了forms.py，它仍然不起作用。关于<代码>和<代码>我的<代码>主题，想法是（不是我的，我可能还没有完全正确地理解它）表示属于函数（
