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(', ') }} .. versionadded:: 2.7 iiiRsUnexpected keyword argument %rismap requires a filter argumentcsjj|dS(Ntcontext(Rt call_filter(R(RRRR(s2/usr/lib/python2.7/site-packages/jinja2/filters.pyRCs N(RtpopR R R-R"Rt LookupError(RRRdRRR((RRRRs2/usr/lib/python2.7/site-packages/jinja2/filters.pytdo_maps"     cOst||dtS(sFilters a sequence of objects by appying a test to either the object or the attribute and only selecting the ones with the test succeeding.
