# this gist can be used to list all targets, or - more correctly - rules,
# that are defined in a Makefile (and possibly other included Makefiles)
# and is inspired by Jack Kelly's reply to a StackOverflow question:
#
#   http://stackoverflow.com/questions/3063507/list-goals-targets-in-gnu-make/3632592#3632592
#
# I also found this script - http://www.shelldorado.com/scripts/cmds/targets - which does
# something similar using awk, but it extracts targets from the "static" rules from a single
# Makefile, meaning it ignores any included Makefiles, as well as targets from "dynamic" rules

Configure Git to use a proxy

In Brief

You may need to configure a proxy server if you're having trouble cloning or fetching from a remote repository or getting an error like unable to access '...' Couldn't resolve host '...'.

Consider something like:

moki9

def truncate_db(engine):
    # delete all table data (but keep tables)
    # we do cleanup before test 'cause if previous test errored,
    # DB can contain dust
    meta = MetaData(bind=engine, reflect=True)
    con = engine.connect()
    trans = con.begin()
    con.execute('SET FOREIGN_KEY_CHECKS = 0;')
    for table in meta.sorted_tables:
        con.execute(table.delete())

# This is just a cheat sheet:

# On production
sudo -u postgres pg_dump database | gzip -9 > database.sql.gz

# On local
scp -C production:~/database.sql.gz
dropdb database && createdb database
gunzip < database.sql.gz | psql database
