Refer to the Django document, you can set CSRF_FAILURE_VIEW in your settings.py, such as:
```
CSRF_FAILURE_VIEW = 'your_app_name.views.csrf_failure'
```
Also, you'll need to define a csrf_failure function in your view (need to have this signature: def csrf_failure(request, reason="") based on the document), which is similar to :
```
def csrf_failure(request, reason=""):
    ctx = {'message': 'some custom messages'}
    return render_to_response(your_custom_template, ctx)
```
And you can write your custom template as:
```
<!DOCTYPE html>
<html>
    <head lang="en">
        <meta charset="UTF-8">
        <title></title>
    </head>
    <body>
        {{ message }}
    </body>
</html>
```

As of Django 1.10, you can simply add and customize the 403_csrf.html template: https://docs.djangoproject.com/en/1.10/ref/settings/#std:setting-CSRF_FAILURE_VIEW

Add 403_csrf.html template to the project template directory.

As you can see in the source code django/views/csrf.py: if you have this template, it will be applied. Nothing needs to be configured.

Template content that you need to customize for your needs:
```
<div id="summary">
  <h1>{{ title }} <span>(403)</span></h1>
  <p>{{ main }}</p>
{% if no_referer %}
  <p>{{ no_referer1 }}</p>
  <p>{{ no_referer2 }}</p>
  <p>{{ no_referer3 }}</p>
{% endif %}
{% if no_cookie %}
  <p>{{ no_cookie1 }}</p>
  <p>{{ no_cookie2 }}</p>
{% endif %}
</div>
```
