Django中的联系表单

Question

我有一个联系表单，运行得很好，没有任何错误。唯一让我不明白的是，当我点击发送按钮时，没有收到任何消息。有人能告诉我为什么或者哪里出问题了吗？我只有一个页面叫做联系，没有感谢页面！谢谢。

这是我的代码：

models.py

class Subject(models.Model):
    question_  = 0
    question_one = 1
    question_two = 2
    question__three = 3

    STATUS_CHOICES = (
        (question_, ''),
        (question_one, 'I have a question'),
        (question_two, 'Help/Support'),
        (question__three, 'Please give me a call'),
        )

class Contact(models.Model):
    name    = models.CharField(max_length=100)
    email   = models.EmailField(max_length=150)
    subject = models.CharField(choices=Subject.STATUS_CHOICES, default=1, max_length=100)
    phone_number  = models.IntegerField()
    message = models.TextField()

    def save(self, *args, **kwargs):
        super(Contact, self).save(*args, **kwargs)
        return 'Contact.save'

forms.py

from crispy_forms.helper import FormHelper
from crispy_forms.layout import Submit
import floppyforms as forms

from django_enumfield import enum

class SubjectEnum(enum.Enum):
    question_  =0
    question_one = 1
    question_two = 2
    question__three = 3

    STATUS_CHOICES = (
        (question_, ''),
        (question_one, 'I have a question'),
        (question_two, 'Help/Support'),
        (question__three, 'Please give me a call'),
        )


class ContactForm(forms.Form):
    name = forms.CharField(required=True)
    email = forms.EmailField(required=True)
    subject = forms.TypedChoiceField(choices=SubjectEnum.STATUS_CHOICES, coerce=str)
    phone_number = forms.IntegerField(required=False)
    message = forms.CharField(widget=forms.Textarea)


    def __init__(self, *args, **kwargs):
        self.helper = FormHelper()
        self.helper.add_input(Submit('submit', 'Submit'))
        super(ContactForm, self).__init__(*args, **kwargs)

views.py

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 = "contact/email_form.jade"
    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="info@example.com",
            recipient_list=[settings.LIST_OF_EMAIL_RECIPIENTS],
        )
        return super(ContactFormView, self).form_valid(form)

Answer 1

这部分可能有问题：

recipient_list=[settings.LIST_OF_EMAIL_RECIPIENTS],

如果 settings.LIST_OF_EMAIL_RECIPIENTS 已经是一个列表了，那么你就把它放在了另一个列表里面。

总的来说，当你遇到代码不工作的情况时，建议你用调试工具逐步检查代码，或者加一些打印语句，看看代码运行时发生了什么。这样会让你更容易找到问题所在。

Answer 2

其实有个更简单、更好的方法来做到这一点。

class Subject(models.Model):
        question_  = 0
        question_one = 1
        question_two = 2
        question__three = 3

    STATUS_CHOICES = (
        (question_, ''),
        (question_one, 'I have a question'),
        (question_two, 'Help/Support'),
        (question__three, 'Please give me a call'),
        )

你不需要新建一个类，只需要这样做。在你看到的0、1、2、3这些数字是用来识别每个选择的。你可以在第一部分放任何东西，比如0、1、2、3，或者用"IHAQ"来表示"I have a question"（我有一个问题）。

STATUS_CHOICES = (
        ("0", ""),
        ("1", "I have a question"),
        ("2", "Help/Support"),
        ("3", "Please give me a call"),
        )
