symfony - show iframe from database row in twig symfony2 -

-

i use twig symfony2

i got following text database:

<iframe src="http://xxx.example.com/embedframe/123456" frameborder=0 width=510 height=400 scrolling=no></iframe>

in twig try show with:

{{ movie.iframe }}

when insert iframe direct in twig-code, iframe shown perfect, when try view variable, view text above.

what did wrong?

twig escapes every output default. output html have use raw filter. have sure, database output safe. 

{{ movie.iframe|raw }}
