Form builder
The wagtailforms module allows you to set up single-page forms, such as a 'Contact us' form, as pages of a Wagtail site. It provides a set of base models that site implementers can extend to create their own FormPage type with their own site-specific templates. Once a page type has been set up in this way, editors can build forms within the usual page editor, consisting of any number of fields. Form submissions are stored for later retrieval through a new 'Forms' section within the Wagtail admin interface; in addition, they can be optionally e-mailed to an address specified by the editor.
**wagtailforms is not a replacement for** [Django's form support](inv:django#topics/forms/index). It is designed as a way for page authors to build general-purpose data collection forms without having to write code. If you intend to build a form that assigns specific behavior to individual fields (such as creating user accounts), or needs a custom HTML layout, you will almost certainly be better served by a standard Django form, where the fields are fixed in code rather than defined on-the-fly by a page author. See the [wagtail-form-example project](https://github.com/gasman/wagtail-form-example/commits/master) for an example of integrating a Django form into a Wagtail page.

Usage
Add wagtail.contrib.forms to your INSTALLED_APPS:
INSTALLED_APPS = [
...
'wagtail.contrib.forms',
]
Within the models.py of one of your apps, create a model that extends wagtail.contrib.forms.models.AbstractEmailForm:
from django.db import models
from modelcluster.fields import ParentalKey
from wagtail.admin.panels import (
FieldPanel, FieldRowPanel,
InlinePanel, MultiFieldPanel
)
from wagtail.fields import RichTextField
from wagtail.contrib.forms.models import AbstractEmailForm, AbstractFormField
class FormField(AbstractFormField):
page = ParentalKey('FormPage', on_delete=models.CASCADE, related_name='form_fields')
class FormPage(AbstractEmailForm):
intro = RichTextField(blank=True)
thank_you_text = RichTextField(blank=True)
content_panels = AbstractEmailForm.content_panels + [
FieldPanel('intro'),
InlinePanel('form_fields', label="Form fields"),
FieldPanel('thank_you_text'),
MultiFieldPanel([
FieldRowPanel([
FieldPanel('from_address', classname="col6"),
FieldPanel('to_address', classname="col6"),
]),
FieldPanel('subject'),
], "Email"),
]
AbstractEmailForm defines the fields to_address, from_address and subject, and expects form_fields to be defined. Any additional fields are treated as ordinary page content - note that FormPage is responsible for serving both the form page itself and the landing page after submission, so the model definition should include all necessary content fields for both of those views.
Date and datetime values in a form response will be formatted with the SHORT_DATE_FORMAT and SHORT_DATETIME_FORMAT respectively. (see [](form_builder_render_email) for how to customize the email content).
If you do not want your form page type to offer form-to-email functionality, you can inherit from AbstractForm instead of AbstractEmailForm, and omit the to_address, from_address, and subject fields from the content_panels definition.
You now need to create two templates named form_page.html and form_page_landing.html (where form_page is the underscore-formatted version of the class name). form_page.html differs from a standard Wagtail template in that it is passed a variable form, containing a Django Form object, in addition to the usual page variable. A very basic template for the form would thus be:
{% load wagtailcore_tags %}
<html>
<head>
<title>{{ page.title }}</title>
</head>
<body>
<h1>{{ page.title }}</h1>
{{ page.intro|richtext }}
<form action="{% pageurl page %}" method="POST">
{% csrf_token %}
{{ form.as_p }}
<input type="submit">
</form>
</body>
</html>
form_page_landing.html is a standard Wagtail template, displayed after the user makes a successful form submission, form_submission will be available in this template. If you want to dynamically override the landing page template, you can do so with the get_landing_page_template method (in the same way that you would with get_template).

Displaying form submission information
FormSubmissionsPanel can be added to your page's panel definitions to display the number of form submissions and the time of the most recent submission, along with a quick link to access the full submission data:
from wagtail.contrib.forms.panels import FormSubmissionsPanel
class FormPage(AbstractEmailForm):
# ...
content_panels = AbstractEmailForm.content_panels + [
FormSubmissionsPanel(),
FieldPanel('intro'),
# ...
]
