template Django - default postinstall script

[matthieumarrast]

Problem

In the django template, the postinstall script is in charge of initiliazing the django project and to make it works with the mfserv/nginx routing.

But this postinstall file must absolutely be emptied or deleted after the first plugin installation, otherwise the initilization is made each time the plugin is installed.

Solution

Add a mention to delete or empty the postinstall script (at the end of the plugin installation) in documentation http://metwork-framework.org/pub/metwork/releases/docs/stable/mfserv/870-tutorials/041_python3_django3_plugin/

For now I do not imagine an automatic solution, as the postinstall script cannot destroy (or empty) itself.

I think to an automatic solution : this shell should test the presence of a file (for example .postinstall.done), do nothing if present and create the file at the end of the shell (at first execution).
