While using {{{ STATICFILES_STORAGE =
'django.contrib.staticfiles.storage.ManifestStaticFilesStorage' }}}
setting, the {{{ collectstatic }}} command was always failing because it
was not able to find a certain file. I am getting the following error:
{{{
ValueError: The file 'netjsongraph/css/lib/"images/ui-
icons_555555_256x240.png"' could not be found with
<django.contrib.staticfiles.storage.ManifestStaticFilesStorage object at
0x7f773b3be520>.
}}}
The peculiar thing to notice is the name of the missing file contains {{{
" }}}. Initially I thought it might me an error in the CSS, but even after
removing all CSS properties using {{{ url() }}} functions, the error was
still there.
The error disappeared only after I removed the comment in the CSS file
which contained {{{ url(%22images%2Fui-icons_555555_256x240.png%22) }}} as
a parameter to some URL.
The {{{ post_process }}} should not try to make substitutions for {{{ url
}}} keyword inside comments. Since it pattern matching is used to make
substitutions, it will be better to process files without comments for
pattern matching.
