# How to add Wagtail into an existing Django project

To install Wagtail completely from scratch, create a new Django project and an app within that project. For instructions on these tasks, see [Writing your first Django app](django:intro/tutorial01). Your project directory will look like the following:

```
myproject/
    myproject/
        __init__.py
        settings.py
        urls.py
        wsgi.py
    myapp/
        __init__.py
        models.py
        tests.py
        admin.py
        views.py
    manage.py
```

From your app directory, you can safely remove `admin.py` and `views.py`, since Wagtail will provide this functionality for your models. Configuring Django to load Wagtail involves adding modules and variables to `settings.py` and URL configuration to `urls.py`. For a more complete view of what's defined in these files, see [Django Settings](django:topics/settings) and [Django URL Dispatcher](django:topics/http/urls).

What follows is a settings reference which skips many boilerplate Django settings. If you just want to get your Wagtail install up quickly without fussing with settings at the moment, see [](complete_example_config).

## Middleware (`settings.py`)

```python
MIDDLEWARE = [
  'django.contrib.sessions.middleware.SessionMiddleware',
  'django.middleware.common.CommonMiddleware',
  'django.middleware.csrf.CsrfViewMiddleware',
  'django.contrib.auth.middleware.AuthenticationMiddleware',
  'django.contrib.messages.middleware.MessageMiddleware',
  'django.middleware.clickjacking.XFrameOptionsMiddleware',
  'django.middleware.security.SecurityMiddleware',

  'wagtail.contrib.redirects.middleware.RedirectMiddleware',
]
```

Wagtail depends on the default set of Django middleware modules, to cover basic security and functionality such as login sessions. One additional middleware module is provided:

**`RedirectMiddleware`**  
 Wagtail provides a simple interface for adding arbitrary redirects to your site and this module makes it happen.

## Apps (`settings.py`)

```python
INSTALLED_APPS = [

  'myapp',  # your own app

  'wagtail.contrib.forms',
  'wagtail.contrib.redirects',
  'wagtail.embeds',
  'wagtail.sites',
  'wagtail.users',
  'wagtail.snippets',
  'wagtail.documents',
  'wagtail.images',
  'wagtail.search',
  'wagtail.admin',
  'wagtail',

  'taggit',
  'modelcluster',

  'django.contrib.auth',
  'django.contrib.contenttypes',
  'django.contrib.sessions',
  'django.contrib.messages',
  'django.contrib.staticfiles',
]
```

Wagtail requires several Django app modules, third-party apps, and defines several apps of its own. Wagtail was built to be modular, so many Wagtail apps can be omitted to suit your needs. Your own app (here `myapp`) is where you define your models, templates, static assets, template tags, and other custom functionality for your site.

### Wagtail Apps

**`wagtail`**  
 The core functionality of Wagtail, such as the `Page` class, the Wagtail tree, and model fields.

**`wagtail.admin`**  
 The administration interface for Wagtail, including page edit handlers.

**`wagtail.documents`**  
 The Wagtail document content type.

**`wagtail.snippets`**  
 Editing interface for non-Page models and objects. See [](Snippets).

**`wagtail.users`**  
 User editing interface.

**`wagtail.images`**  
 The Wagtail image content type.

**`wagtail.embeds`**  
 Module governing oEmbed and Embedly content in Wagtail rich text fields. See [](inserting_videos).

**`wagtail.search`**  
 Search framework for Page content. See [](wagtailsearch).

**`wagtail.sites`**  
 Management UI for Wagtail sites.

**`wagtail.contrib.redirects`**  
 Admin interface for creating arbitrary redirects on your site.

**`wagtail.contrib.forms`**  
 Models for creating forms on your pages and viewing submissions. See [Form builder](form_builder).

### Third-Party Apps

**`taggit`**  
 Tagging framework for Django. This is used internally within Wagtail for image and document tagging and is available for your own models as well. See [](tagging) for a Wagtail model recipe or the [Taggit Documentation](https://django-taggit.readthedocs.io/en/stable/).

**`modelcluster`**  
 Extension of Django ForeignKey relation functionality, which is used in Wagtail pages for on-the-fly related object creation. For more information, see [](inline_panels) or [the django-modelcluster github project page](https://github.com/wagtail/django-modelcluster).

## URL Patterns

```python
from django.contrib import admin

from wagtail import urls as wagtail_urls
from wagtail.admin import urls as wagtailadmin_urls
from wagtail.documents import urls as wagtaildocs_urls

urlpatterns = [
    path('django-admin/', admin.site.urls),

    path('admin/', include(wagtailadmin_urls)),
    path('documents/', include(wagtaildocs_urls)),

    # Optional URL for including your own vanilla Django urls/views
    re_path(r'', include('myapp.urls')),

    # For anything not caught by a more specific rule above, hand over to
    # Wagtail's serving mechanism
    re_path(r'', include(wagtail_urls)),
]
```

This block of code for your project's `urls.py` does a few things:

-   Load the vanilla Django admin interface to `/django-admin/`
-   Load the Wagtail admin and its various apps
-   Dispatch any vanilla Django apps you're using other than Wagtail which require their own URL configuration (this is optional, since Wagtail might be all you need)
-   Lets Wagtail handle any further URL dispatching.

That's not everything you might want to include in your project's URL configuration, but it's what's necessary for Wagtail to flourish.
