python之使用 ModelForm 的 Django 联系表单

我正在尝试创建一个既可以通过电子邮件发送又可以存储消息的联系表单。我想我得到了 model.py、forms.py 和 admin.py，并且我能够创建和存储(不是电子邮件) 来自管理员的消息。但是我正在努力处理必须同时通过电子邮件发送和存储消息的 view.py。

模型.py:

from django.db import models 
from django.contrib import admin 
 
class Contact(models.Model): 
    name = models.CharField(max_length=100) 
    email = models.EmailField() 
    message = models.TextField(max_length=10)  
    date_created = models.DateField(verbose_name="Created on date", auto_now_add="True") 
 
class ContactAdmin(admin.ModelAdmin): 
    list_display = ('name', 'email', 'message', 'date_created') 

表单.py:

from django import forms 
from .models import Contact 
 
 
class ContactForm(forms.Form): 
    name = forms.CharField() 
    email = forms.EmailField() 

当谈到 views.py 时，我需要一些指导才能将 def contact(request): 的代码放在一起。我想我必须包括这些模块:

from django.conf import settings 
from django.shortcuts import render, HttpResponseRedirect, HttpResponse, Http404 
from django.core.mail import send_mail 
from .forms import ContactForm 
from .models import Contact 

关于模板部分，我不确定如何使用模板标签在 html 中呈现联系表单。

所以，我需要帮助来找出正确的view 和template 代码。我当然也乐于接受有关其余代码的建议 - As你可能猜到了，这是我的第一个真正的 Django 应用程序。

谢谢!

请您参考如下方法:

像这样:

我会使用 django ModelForm 来生成表单:

class ContactForm(forms.ModelForm): 
 
    class Meta: 
        model = Contact 
        exclude = ('date_created', ) 

文档:https://docs.djangoproject.com/en/1.7/topics/forms/modelforms/#modelform

和实际 View 的 FormView:

from django.conf import settings 
from django.core.mail import send_mail 
from django.views.generic import FormView 
 
from .forms import ContactForm 
 
class ContactFormView(FormView): 
 
    form_class = ContactForm 
    template_name = "email_form.html" 
    success_url = '/email-sent/' 
 
    def form_valid(self, form): 
        message = "{name} / {email} said: ".format( 
            name=form.cleaned_data.get('name'), 
            email=form.cleaned_data.get('email')) 
        message += "\n\n{0}".format(form.cleaned_data.get('message')) 
        send_mail( 
            subject=form.cleaned_data.get('subject').strip(), 
            message=message, 
            from_email='contact-form@myapp.com', 
            recipient_list=[settings.LIST_OF_EMAIL_RECIPIENTS], 
        ) 
        form.save() 
        return super(ContactFormView, self).form_valid(form) 

文档:https://docs.djangoproject.com/en/1.7/ref/class-based-views/generic-editing/#formview

还有你的模板:

{% extends 'base.html' %} 
{% block title %}Send an email{% endblock %} 
 
{% block content %} 
    <div class="row"> 
        <div class="span6"> 
            <h1>Send an email</h1> 
            <form action="." method="post"> 
                {% csrf_token %} 
                {{ form }} 
                <input type="submit" value="Submit" /> 
            </form> 
        </div> 
    </div> 
{% endblock %} 
 
{% block extrajs %} 
<script src="{{ STATIC_URL }}js/jquery-1.7.1.min.js"></script> 
<script type="text/javascript"> 
$(function() { 
    $('#id_name').focus() 
}); 
</script> 
{% endblock %}
