如何使用Django制作简单的联系表单？

I am new to Django 1.9 and I am currently coding a website. I am trying to make a contact form to go on the contact page. I have used the following code - which is in the a file called email.html:

我是Django 1.9的新手,我目前正在编写一个网站。我正在尝试联系表单以进入联系页面。我使用了以下代码 - 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>

I've defined it in the view.py file:

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.')

.....

As well as in the forms.py file:

以及forms.py文件中:

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)

Also, in the urls.py file:

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'),
 ]

When I link the email.html file to the main page and click on the link and it just shows the home page even though the url says I am on the email.html page (shown below):

当我将email.html文件链接到主页并点击链接时,它只显示主页,即使网址显示我在email.html页面上(如下所示):

I am totally new to programming in Django. I have tried researching it however, I can't find a solution. Please can someone help me.

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

Your URLs are most likely the problem. You can read more on Django URLs here.

您的网址很可能是问题所在。您可以在此处阅读有关Django URL的更多信息。

Note, as the Django docs mention, the first URL pattern which matches the requested URL will be used. As a basic rule of thumb, I recommend putting your more specific URL patterns before your blank url patterns. For instance:

请注意,正如Django文档所提到的,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'),
]

If this urls.py file is being included from a project urls.py file, you'll want these urls to be included before your root url pattern.

如果从项目urls.py文件中包含此urls.py文件,则您希望在根URL模式之前包含这些URL。

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

Which would then make your url to this page

然后,这将使您的网址到这个页面

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

Which would render as

哪个会呈现为

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