Your first Wagtail site
=======================
1. Install Wagtail and its dependencies:
``pip install wagtail``
2. Start your site:
``wagtail start mysite``
Wagtail provides a ``start`` command similar to
``django-admin.py startproject``. Running ``wagtail start mysite`` in
your project will generate a new ``mysite`` folder with a few
Wagtail-specific extras, including the required project settings, a
"home" app with a blank ``HomePage`` model and basic templates and a sample
"search" app.
3. Create the database:
``python manage.py migrate``
If you haven't updated the project settings, this will be a SQLite
database file in the project directory.
4. Create an admin user:
``python manage.py createsuperuser``.
5. ``python manage.py runserver`` If everything worked,
http://127.0.0.1:8000 will show you a welcome page

:alt: Wagtail welcome message
You can now access the administrative area at ``/admin``

Extend the HomePage model
-------------------------
Out of the box you get a blank ``HomePage`` model and the "home" app has a
migration that creates a homepage and configures Wagtail to use it.
This example extends the HomePage model to add a body field.
.. code:: python
from django.db import models
from wagtail.wagtailcore.models import Page
from wagtail.wagtailcore.fields import RichTextField
from wagtail.wagtailadmin.edit_handlers import FieldPanel
class HomePage(Page):
body = RichTextField(blank=True)
content_panels = Page.content_panels + [
FieldPanel('body')
]
``body`` is defined as ``RichTextField``, a special Wagtail field. You
can use any of the `Django core fields <https://docs.djangoproject.com/en/1.8/ref/models/fields/>`__. ``content_panels`` define the
capabilities and the layout of the editing interface. :doc:`More on creating Page models. <../topics/creating_pages>`
Run ``python manage.py makemigrations``, then
``python manage.py migrate`` to update the database with your model
changes. You must run the above commands each time you make changes to
the model definition.
To reflect the model changes, edit
``core/templates/core/home_page.html``. Wagtail uses normal Django
templates to render each page type. It automatically generates a
suggestion by separating capital letters with underscores (e.g. HomePage
becomes home\_page.html).
.. code:: html+django
{% extends "base.html" %}
{% load static core_tags wagtailcore_tags %}
{% block body_class %}template-homepage{% endblock %}
{% block content %}
{{ self.body|richtext }}
{% endblock %}
.. figure:: ../_static/images/tutorial/tutorial_3.png
:alt: Updated homepage
A basic blog
------------
We are now ready to create a blog. To do so, run
``python manage.py startapp blog`` to create a new app in your Wagtail site.
Add the new ``blog`` app to ``INSTALLED_APPS`` in ``mysite/settings/base.py``.
The following example defines a basic blog post model in ``blog/models.py``
.. code:: python
from django.db import models
from wagtail.wagtailcore.models import Page
from wagtail.wagtailcore.fields import RichTextField
from wagtail.wagtailadmin.edit_handlers import FieldPanel
from wagtail.wagtailsearch import index
class BlogPage(Page):
date = models.DateField("Post date")
intro = models.CharField(max_length=250)
body = RichTextField(blank=True)
search_fields = Page.search_fields + (
index.SearchField('intro'),
index.SearchField('body'),
)
content_panels = Page.content_panels + [
FieldPanel('date'),
FieldPanel('intro'),
FieldPanel('body', classname="full")
]
Run ``python manage.py makemigrations`` and ``python manage.py migrate``.

Image support
~~~~~~~~~~~~~
Wagtail provides support for images out of the box. To add them to your
model:
.. code:: python
from django.db import models
from wagtail.wagtailcore.models import Page
from wagtail.wagtailcore.fields import RichTextField
from wagtail.wagtailadmin.edit_handlers import FieldPanel
from wagtail.wagtailimages.edit_handlers import ImageChooserPanel
from wagtail.wagtailsearch import index
class BlogPage(Page):
main_image = models.ForeignKey(
'wagtailimages.Image',
null=True,
blank=True,
on_delete=models.SET_NULL,
related_name='+'
)
date = models.DateField("Post date")
intro = models.CharField(max_length=250)
body = RichTextField(blank=True)
search_fields = Page.search_fields + (
index.SearchField('intro'),
index.SearchField('body'),
)
content_panels = Page.content_panels + [
FieldPanel('date'),
ImageChooserPanel('main_image'),
FieldPanel('intro'),
FieldPanel('body'),
]
Adjust your BlogPage template to output the image:
.. code:: html+django
{% extends "base.html" %}
{% load static core_tags wagtailcore_tags wagtailimages_tags %}
{% block body_class %}templage-blogpage{% endblock %}
{% block content %}
<h1>{{ self.title }}</h1>
<p class="meta">{{ self.date }}</p>
{% if self.main_image %}
{% image self.main_image width-400 %}
{% endif %}
<div class="intro">{{ self.intro }}</div>
{{ self.body | richtext }}
{% endblock %}
.. figure:: ../_static/images/tutorial/tutorial_6.png
:alt: A blog post sample
You can read more about using images in templates in the
:doc:`docs <../topics/images/index>`.
Blog Index
~~~~~~~~~~
Let us extend the Blog app to provide an index.
.. code:: python
class BlogIndexPage(Page):
intro = RichTextField(blank=True)
content_panels = Page.content_panels + [
FieldPanel('intro', classname="full")
]
The above creates an index type to collect all our blog posts.
``blog/templates/blog/blog_index_page.html``
.. code:: html+django
{% extends "base.html" %}
{% load static core_tags wagtailcore_tags %}
{% block body_class %}template-blogindexpage{% endblock %}
{% block content %}
<h1>{{ self.title }}</h1>
<div class="intro">{{ self.intro }}</div>
{% endblock %}
Related items
~~~~~~~~~~~~~
Let's extend the BlogIndexPage to add related links. The related links
can be BlogPages or external links. Change ``blog/models.py`` to
.. code:: python
from django.db import models
from modelcluster.fields import ParentalKey
from wagtail.wagtailcore.models import Page, Orderable
from wagtail.wagtailcore.fields import RichTextField
from wagtail.wagtailadmin.edit_handlers import (FieldPanel,
InlinePanel,
MultiFieldPanel,
PageChooserPanel)
from wagtail.wagtailimages.edit_handlers import ImageChooserPanel
from wagtail.wagtailsearch import index
# ...
class LinkFields(models.Model):
link_external = models.URLField("External link", blank=True)
link_page = models.ForeignKey(
'wagtailcore.Page',
null=True,
blank=True,
related_name='+'
)
@property
def link(self):
if self.link_page:
return self.link_page.url
else:
return self.link_external
panels = [
FieldPanel('link_external'),
PageChooserPanel('link_page'),
]
class Meta:
abstract = True
# Related links
class RelatedLink(LinkFields):
title = models.CharField(max_length=255, help_text="Link title")
panels = [
FieldPanel('title'),
MultiFieldPanel(LinkFields.panels, "Link"),
]
class Meta:
abstract = True
class BlogIndexRelatedLink(Orderable, RelatedLink):
page = ParentalKey('BlogIndexPage', related_name='related_links')
class BlogIndexPage(Page):
intro = RichTextField(blank=True)
content_panels = Page.content_panels + [
InlinePanel('related_links', label="Related links"),
]
.. figure:: ../_static/images/tutorial/tutorial_7.png
:alt: Blog index edit screen
Extend ``blog_index_page.html`` to show related items
.. code:: html+django
{% extends "base.html" %}
{% load static core_tags wagtailcore_tags %}
{% block body_class %}template-blogindexpage{% endblock %}
{% block content %}
<h1>{{ self.title }}</h1>
<div class="intro">{{ self.intro }}</div>
{% if self.related_links.all %}
<ul>
{% for item in self.related_links.all %}
<li><a href="{{ item.link }}">{{ item.title }}</a></li>
{% endfor %}
</ul>
{% endif %}
{% endblock %}
You now have a fully working blog with featured blog posts.
