Fixes #14780 -- bad quoting in class based views reference. Thanks for the patch, adamv.

    Since this is a subclass of

    :class:`~django.views.generic.detail.SingleObjectMixin`, instances of this

    mixin have access to the :attr:`~SingleObjectMixin.model`` and

    :attr:`~SingleObjectMixin.queryset`` attributes, describing the type of

    mixin have access to the :attr:`~SingleObjectMixin.model` and

    :attr:`~SingleObjectMixin.queryset` attributes, describing the type of

    object that the ModelForm is manipulating. The view also provides

    ``self.object``, the instance being manipulated. If the instance is being

    created, ``self.object`` will be ``None``

        Retrieve the form class to instantiate. If

        :attr:`FormMixin.form_class` is provided, that class will be used.

        Otherwise, a ModelForm will be instantiated using the model associated

        with the :attr:`~SingleObjectMixin.queryset``, or with the

        :attr:`~SingleObjectMixin.model``, depending on which attribute is

        with the :attr:`~SingleObjectMixin.queryset`, or with the

        :attr:`~SingleObjectMixin.model`, depending on which attribute is

        provided.

    .. method:: get_form(form_class)

    .. method:: get_next_month(date)

        Returns a date object containing the first day of the month after the

        date provided. Returns `None`` if mixed with a view that sets

        date provided. Returns ``None`` if mixed with a view that sets

        ``allow_future = False``, and the next month is in the future. If

        ``allow_empty = False``, returns the next month that contains data.

    .. method:: get_next_day(date)

        Returns a date object containing the next day after the date provided.

        Returns `None`` if mixed with a view that sets ``allow_future = False``,

        Returns ``None`` if mixed with a view that sets ``allow_future = False``,

        and the next day is in the future. If ``allow_empty = False``, returns

        the next day that contains data.

        Returns the list of dates of type ``date_type`` for which

        ``queryset`` contains entries. For example, ``get_date_list(qs,

        'year')`` will return the list of years for which ``qs`` has entries.

        ways that the ``date_type`` argument can be used.
