Can Django collectstatic overwrite old files?
Question: In my deb postinst file:

    
    
    PYTHON=/usr/bin/python
    PYTHON_VERSION=`$PYTHON -c 'import sys; print sys.version[:3]'`
    SITE_PACKAGES=/opt/pkgs/mypackage/lib/python$PYTHON_VERSION/site-packages
    export PYTHONPATH=$SITE_PACKAGES
    echo "collect static files"
    $PYTHON manage.py collectstatic --noinput 
    

> When I run 'dpkg -i mypackage.deb' to install the package, no problem.
>
> When I run 'dpkg -i mypackage.deb' to **re-install the package, old css
> files unchanged**.
>
> When I changed '$PYTHON manage.py collectstatic \--noinput ' to '$PYTHON
> manage.py collectstatic --noinput -c' and run 'dpkg -i mypackage.deb' to
> **re-install the package** , the error is following: OSError: [Errno 2] No
> such file or directory: '/opt/pkgs/myporject/static'

Any idea?

**Can Django collectstatic overwrite old files?**


Answer: (Added here, maybe someone will have same problems with mine.) Yes.

The timestamp of css files in /opt/pkgs/mypropject/lib/python2.7/site-
packages/mypropject-py2.7.egg/myapp/static/css (directory A) is the time when
package building finished, not the time when css files installed.

But the timestamp of css files in /opt/pkgs/myporject/static (directory B) is
the time of installation.

That is why collectstatic sometimes cannot overwrite my old css files (cannot
copy some css files from directory A to directory B).
