    Renders a contact form, validates its input and sends an email

    To specify the form class to use, pass the ``form_class`` keyword
    argument; if no ``form_class`` is specified, the base
    ``ContactForm`` class will be used.
    
    To specify the template to use for rendering the form (*not* the
    template used to render the email message sent from the form,
    which is handled by the form class), pass the ``template_name``
    keyword argument; if not supplied, this will default to
    ``contact_form/contact_form.html``.

    pass the ``success_url`` keyword argument; if not supplied, this
    will default to ``/contact/sent/``.
    
    To allow only registered users to use the form, pass a ``True``
    value for the ``login_required`` keyword argument.

    ``True`` value for the ``fail_silently`` keyword argument. This is
    **not** recommended.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
