Question

我是Django 1.9的新手，我正在编写一个网站。我正在尝试联系表单以进入联系页面。我使用了以下代码 - 它位于名为email.html的文件中：

{% extends 'blog/base.html' %}
<form method="post">
    {% csrf_token %}
    {{ form }}
    <div class="form-actions">
      <button type="submit">Send</button>
    </div>
 </form>

我在view.py文件中定义了它：

from .forms import PostForm, ContactForm
from django.http import HttpResponse, HttpResponseRedirect
from django.shortcuts import redirect
from django.core.mail import send_mail, BadHeaderError
from django.http import HttpResponse, HttpResponseRedirect
from django.shortcuts import render, redirect

def email(request):
    if request.method == 'GET':
        form = ContactForm()
    else:
        form = ContactForm(request.POST)
        if form.is_valid():
            subject = form.cleaned_data['subject']
            from_email = form.cleaned_data['from_email']
            message = form.cleaned_data['message']
            try:
                send_mail(subject, message, from_email, ['nmam.ltd@gmail.com'])
            except BadHeaderError:
                return HttpResponse('Invalid header found.')
            return redirect('thanks')
    return render(request, "blog/email.html", {'form': form})

def thanks(request):
    return HttpResponse('Thank you for your message.')

.....

以及forms.py文件：

from django import forms

class ContactForm(forms.Form):
    from_email = forms.EmailField(required=True)
    subject = forms.CharField(required=True)
    message = forms.CharField(widget=forms.Textarea)

另外，在urls.py文件中：

from django.conf.urls import patterns, url
from . import views

urlpatterns = [
    url(r'^general.html/$', views.general, name='general'),
    url(r'^dcmain.html/$', views.dcmain, name='dcmain'),
    url(r'^dcmain.html/big_data.html/$', views.big_data, name='big_data'),
    url(r'^dcmain.html/Data_Architecture.html/$', views.Data_Architecture, name='Data_Architecture'),
    url(r'^dcmain.html/BI_MI.html/$', views.BI_MI, name='BI_MI'),
    url(r'^dcmain.html/Master_Data.html/$', views.Master_Data, name='Master_Data'),
    url(r'^dcmain.html/Data_Q.html/$', views.Data_Q, name='Data_Q'),
    url(r'^dcmain.html/Project_M.html/$', views.Project_M, name='Project_M'),
    url(r'^email.html/$', views.email, name='email'),
    url(r'^thanks/$', views.thanks, name='thanks'),
 ]

当我将email.html文件链接到主页并点击该链接时，即使网址显示我在email.html页面上显示主页（如下所示），它也会显示主页：

我对Django编程完全不熟悉。我试过研究它，但我找不到解决方案。请有人帮助我。

您的网址很可能是问题所在。您可以阅读有关Django网址here的更多信息。

请注意，正如Django文档所述，将使用与请求的URL匹配的第一个URL模式。作为一个基本的经验法则，我建议您在空白网址模式之前添加更具体的网址格式。例如：

urlpatterns = [
    url(r'^email.html/$', views.email, name='email'),
    url(r'^thanks/$', views.thanks, name='thanks'),
    url(r'^$', views.index, name='some_name'),
]

如果从项目urls.py文件中包含此urls.py文件，您将希望在根网址模式之前包含这些网址。

urlpatterns = [
    url(r'^blog/', include('blog.urls', namespace='blog'),
    url(r'', views.site_home, name='site_home'),
]

然后将您的网址设为此页面

<a href="{% url 'blog:email' %}">Email</a>

将呈现为

<a href="yoursite.com/blog/email.html">Email</a>
