将Django crispy表单与FormView混合使用

我想在网站上创建一个Django联系表单,我发现Django crispy表单非常有用,但事实证明我不能将它与Django FormView混合使用。 Crispy表单在前端布局中做了很棒的工作,但是我无法从填充的表单中获取任何信息到我的Django应用程序。我已经尝试过本教程:Simple Django email form using CBV,但它已经过时,根本没用。这是我的forms.py:

from django import forms
from crispy_forms.helper import FormHelper
from crispy_forms.layout import Submit

class ContactForm(forms.Form):

    name = forms.CharField(
        label = "Name:",
        max_length = 80,
        required = True,
    )

    email = forms.CharField(
        label = "E-mail:",
        max_length = 80,
        required = True,
    )

    subject = forms.CharField(
        label = "Subject:",
        max_length = 80,
        required = True,
    )

    message = forms.CharField(
        widget = forms.Textarea,
        label = "Message:",
        required = True,
    )

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

views.py:

from django.shortcuts import render
from myapp.forms import ContactForm

from django.core.mail import send_mail
from django.views.generic.edit import FormView

class ContactFormView(FormView):

    form_class = ContactForm
    template_name = "myapp/contact.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=['mymail@mydomain.com'],
        )
        return super(ContactFormView, self).form_valid(form)

def contact(request):
    contact_form = ContactFormView()
    return render(request, 'myapp/contact.html', {'contact_form': contact_form})

和我的模板contact.html:

{% extends "layout.html" %}
{% load crispy_forms_tags %}

{% block title %}Contact{% endblock %}

{% block content %}
    <h2><b>Contact</b></h2>
    <div class="container">
        <p>You can e-mail me at: <a href="mailto:mymail@mydomain.com">mymail@mydomain.com</a></p>
        <br>
        <p>Or simply fill the form below:</p>
        <br>
        {% crispy contact_form %}
    </div>
{% endblock %}

我得到的是:

Exception Type: TypeErrorException Value:   
'ContactFormView' object is not iterable

有关如何在Django FormView中使用Django crispy表单的任何建议吗?

答案 0 :(得分:2)

这与脆皮表格无关。问题在于这段代码,您将ContactFormView视为表单。

def contact(request):
    contact_form = ContactFormView()
    return render(request, 'myapp/contact.html', {'contact_form': contact_form})

但是,ContactFormView不是表单,而是基于类的视图。您不需要定义另一个视图contact,您已经拥有了一个视图ContactFormView

更改您的网址格式以使用基于类的视图:

url(r'^contact/$', ContactFormView.as_view(), name='contact')

然后在您的模板中,将表单包含在:

{{ form }}}

一旦视图使用常规表单,请使用crispy标签,以便按照您的意愿设置样式:

{% crispy form %}
