    Base class for all dashboard modules.
    Dashboard modules have the following properties:

    ``enabled``
        Boolean that determines whether the module should be enabled in
        the dashboard by default or not. Default value: ``True``.

    ``draggable``
        Boolean that determines whether the module can be draggable or not.
        Draggable modules can be re-arranged by users. Default value: ``True``.

    ``collapsible``
        Boolean that determines whether the module is collapsible, this
        allows users to show/hide module content. Default: ``True``.

    ``deletable``
        Boolean that determines whether the module can be removed from the
        dashboard by users or not. Default: ``True``.

    ``title``
        String that contains the module title, make sure you use the django
        gettext functions if your application is multilingual.
        Default value: ''.

    ``title_url``
        String that contains the module title URL. If given the module
        title will be a link to this URL. Default value: ``None``.

    ``css_classes``
        A list of css classes to be added to the module ``div`` class
        attribute. Default value: ``None``.

    ``pre_content``
        Text or HTML content to display above the module content.
        Default value: ``None``.

    ``content``
        The module text or HTML content. Default value: ``None``.

    ``post_content``
        Text or HTML content to display under the module content.
        Default value: ``None``.

    ``template``
        The template to use to render the module.

    A module that displays a list of links.
    As well as the ``DashboardModule`` properties, the
    ``LinkListDashboardModule`` takes an extra keyword argument:

    ``layout``
        The layout of the list, possible values are ``stacked`` and ``inline``.
        The default value is ``stacked``.

    Link list modules children are simple python dictionaries that can have the
    following keys:

    ``title``
        The link title.

    ``url``
        The link URL.

    ``external``
        Boolean that indicates whether the link is an external one or not.

    ``description``
        A string describing the link, it will be the ``title`` attribute of
        the html ``a`` tag.

        appear in the dashboard module.

        A list of apps to include, only apps whose name (e.g.

        "django.contrib") in the list will appear in the dashboard module.

class ModelListDashboardModule(DashboardModule, AppListElementMixin):
    """
    Module that lists a set of models.
    As well as the ``DashboardModule`` properties, the
    ``ModelListDashboardModule`` takes two extra keyword arguments:

    ``include_list``
        A list of models to include, only models whose name (e.g.
        "blog.comments.Comment") starts with one of the strings (e.g. "blog")
        in the include list will appear in the dashboard module.

    ``exclude_list``
        A list of models to exclude, if a model name (e.g.
        "blog.comments.Comment" starts with an element of this list (e.g.
        "blog.comments") it won't appear in the dashboard module.

    Here's a small example of building a model list module::

        from admin_tools.dashboard import modules, Dashboard

        class MyDashboard(Dashboard):
            def __init__(self, **kwargs):

                ))

    The screenshot of what this code produces:

        Note that this module takes into account user permissions, for
        example, if a user has no rights to change or add a ``Group``, then
        the django.contrib.auth.Group model line will not be displayed.

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.
