The paths inside statcosti.html are absolute to the filesystem of your machine, so they don't make sense for the web server
For example <img src='/var/www/magazantea/templates/R2HTML/grafico2.png' border=1 width=600> resolves to (asuming localhost at port 8000) http://localhost:8000/var/www/magazantea/templates/R2HTML/grafico2.png So your browser makes a request to Django for that path and the server has no idea how to resolve it as its is not in its urls.py rules or a static /media file served by STATIC_URL or MEDIA_URL On Wed, May 6, 2015 at 1:09 PM, Victor <[email protected]> wrote: > Production Context, Ubuntu 14.04, Django 1.7.7 & Apache2 > > Dear experts, > > I'm stranded! > What I would like to do is: > 1) to provide an initial and final date to make some statistical > computation in that period, > 2) pass those dates to an R procedure which by means of the package R2HTML > produces an html file ("statcosti.html"), > 3) watch ecstatically and with emotion at the results of computation in my > browser. > > I 've been able to make step 1) and 2) but only partially step 3).
