# FATAL:  lock file "postmaster.pid" already exists
# HINT:  Is another postmaster (PID 4646) running in data directory "/usr/local/var/postgres"?

# To fix this:

cat /usr/local/var/postgres/postmaster.pid # pid is the number on first line
kill -9 1116 # replace 1116 with pid number (first line) from postmaster.pid file

Nestable, sortable and dragable categories:

In the project I'm working on we wanted to have a Category model which we wanted to be nestable. But we also liked the user to have a draggable interface to manage and rearrange the order of his categories. So we chose awesome_nested_set for the model and jQuery.nestedSortable for the UI.

It took me some time to arrange things to work properly so I wanted to share my work in case it helps anybody.

Before beginning

you might want to take a look at a demo app

1. go to: http://awesomenestedsortable.heroku.com/groups/
2. click in show of any group
