    It is also possible to sort by an attribute (for example to sort

the number to a given precision. The first

    second the rounding method:

    - ``'common'`` rounds either up or down
    - ``'ceil'`` always rounds up

a sequence of objects by a common attribute.

    If you for example have a list of dicts or objects that represent
persons
    with `gender`, `first_name` and `last_name` attributes and you want to
    group all users by genders you can do something like the following
    snippet:

    .. sourcecode:: html+jinja

        <ul>
        {% for group in persons|groupby('gender') %}
            <li>{{ group.grouper }}<ul>
            {% for person in group.list %}
                <li>{{ person.first_name }} {{ person.last_name
}}</li>
            {% endfor %}</ul></li>
        {% endfor %}
        </ul>

    Additionally it's possible to use tuple unpacking for the grouper
and
    list:

    .. sourcecode:: html+jinja

        <ul>
        {% for grouper, list in persons|groupby('gender') %}
            ...
        {% endfor %}
        </ul>

    As you can see the item we're grouping by is stored in the
`grouper`
    attribute and the `list` contains all the objects that have this
grouper
    in common.

    .. versionchanged:: 2.6
       It's now possible to use dotted notation to group by the child
       attribute of another attribute.

s�Applies a filter on a sequence of objects or looks up an attribute.
    This is useful when dealing with lists of objects but you are really
    only interested in a certain value of it.

    The basic usage is mapping on an attribute.  Imagine you have a list
    of users but you are only interested in a list of usernames:

    .. sourcecode:: jinja

        Users on this page: {{
users|map(attribute='username')|join(', ') }}

    Alternatively you can let it invoke a filter by passing the name of the
    filter and the arguments afterwards.  A good example would be applying
a
    text conversion filter on a sequence:

    .. sourcecode:: jinja

        Users on this page: {{ titles|map('lower')|join(',
') }}
