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 N( t prepare_map( R� R� Rx Rd R ( ( s2 /usr/lib/python2.7/site-packages/jinja2/filters.pyt do_map� s c O s t | | d � t � S( s� Filters a sequence of objects by applying a test to each object, and only selecting the objects with the test succeeding.

It accepts the same arguments and returns a JSON string. Note that this is available in templates through the ``|tojson`` filter which will also mark the result as safe. Due to how this function escapes certain characters this is safe even if used outside of ``<script>`` tags. The following characters are escaped in strings: - ``<`` - ``>`` - ``&`` - ``'`` This makes it safe to embed such strings in any place in HTML with the notable exception of double quoted attributes. In that case single quote your attributes or HTML escape it in addition. The indent parameter can be used to enable pretty printing. Set it to the number of spaces that the structures should be indented with. Note that this filter is for use in HTML contexts only. .. versionadded:: 2.9 s json.dumps_functions json.dumps_kwargst indentt dumperN( R R� R R0 R ( R8 R R� R� R t options( ( s2 /usr/lib/python2.7/site-packages/jinja2/filters.pyt do_tojson" s c s� � d � � d } t � � d k r{ d � k r{ � j d � } � rf t d t t � � � � � n t � j | � } nP y � d � � d � Wn t k r� t d � � n X� � � � f d � } | | f S( Ni i i R s Unexpected keyword argument %ri s map requires a filter argumentc s � j j � | � � d � �S( NR ( R t call_filter( R ( R� R R� R� ( s2 /usr/lib/python2.7/site-packages/jinja2/filters.pyR� U s ( R� R� R Ra R1 R' R t LookupError( R� R� Rx R Rd ( ( R� R R� R� s2 /usr/lib/python2.7/site-packages/jinja2/filters.pyR� E s c s� � d � � d } | rc y � d } Wn t k rG t d � � n Xt � j | � � d } n d } d � � y8 � d | � � d | � � � � � f d � � Wn t k r� t � n X| � � � f d � f S( Ni i i s$ Missing parameter for attribute namec S s | S( N( ( R& ( ( s2 /usr/lib/python2.7/site-packages/jinja2/filters.pyR� g RP i c s � j j � | � � � S( N( R t call_test( R ( R� R R� R� ( s2 /usr/lib/python2.7/site-packages/jinja2/filters.pyR� l s c s � � � | � � � S( N( ( R ( Rd t modfunct transfunc( s2 /usr/lib/python2.7/site-packages/jinja2/filters.pyR� q RP ( R R R' R t bool( R� R� R t lookup_attrRx t attrt off( ( R� R Rd R� R R� R s2 /usr/lib/python2.7/site-packages/jinja2/filters.pyt prepare_select_or_reject[ s$ c c sM t | | | | � \ } } | rI x% | D] } | | � r( | Vq( q( Wn d S( N( R ( R� R� R R Rx Rd R ( ( s2 /usr/lib/python2.7/site-packages/jinja2/filters.pyR� t s t absR t batchRN Ru R< RI R� t dictsortt eR t filesizeformatRf R� t forceescapeRF R R� R% R3 t lastR� R t mapRh Rj t pprintR| t rejectt rejectattrR7 RV R� t safet selectt selectattrt slicet sortt stringR� R� t titlet trimt truncatet uniqueR> t urlencodeR t wordcountt wordwrapt xmlattrt tojson(c t __doc__t reR� R| R� t itertoolsR R t collectionsR t jinja2.utilsR R R R R R R t jinja2.runtimeR t jinja2.exceptionsR t jinja2._compatR R R R R t compilet UNICODER� RQ R R R R R R' R* R5 R= R?
