python - Jinja - Indentation in a recursive loop with dictionary -

i'm trying write template using ninja. can't display right indentation! tried lot of stuffs couldn't expected result. have dictionary this:

videonode = {'type': "videoloader",             'config': {'type': "url",                        'source': "blabla",                        'framebuffersize': 50,                       }             } 

i display that

queuevideo1:     type: videoloader     config:         source: blabla         type: url         framebuffersize: 50 

but can is:

queuevideo1:     type: videoloader config:    source: blabla type: url framebuffersize: 50 

here file:

{%- key, value in videonodes.iteritems() recursive -%}     {%+ if value mapping -%}         {{ key }}:         {{ loop(value.iteritems()) }}     {%- else -%}        {{ key }}: {{value}}     {% endif %} {%- endfor -%} 

you must try using indent function , asign value depends of level of indentation:

{{ key|indent(2, true) }} 

you can see the documentation here
