Python Fabric error

Question

I'm running fabric (Django deployment to apache) and everything seems to work fine until I get to the task for installing the site:

def install_site():
    "Add the virtualhost file to apache"
    require('release', provided_by=[deploy, setup])
    sudo('cd %(path)/releases/%(release)/%(release); cp %(project_name)/%(virtualhost_path)/%(project_domain) /etc/apache2/sites-available/%(project_domain)s')
    sudo('cd /etc/apache2/sites-available; a2ensite %(project_domain)') 

I keep getting this error:

[173.203.124.16] sudo: cd %(path)/releases/%(release)/%(release);
[173.203.124.16] err: /bin/bash: -c: line 0: syntax error near unexpected token
`('
[173.203.124.16] err: /bin/bash: -c: line 0: `cd %(path)/releases/%(release)/%(r
elease);'

Warning: sudo() encountered an error (return code 2) while executing 'cd %(path)
/releases/%(release)/%(release);'

I've gone through the fabfile.py over and over and I can't see why the error is coming...any ideas?

Answer 1

You might want to try using the cd context manager. You're probably also having problems with your string interpolation.

def install_site():
    # Add the virtualhost file to apache
    require('release', provided_by=[deploy, setup])

    with cd('%s/releases/%s/%s' % (path, release, release)):
        sudo('cp %s/%s/%s /etc/apache2/sites-available/%s' % (project_name, virtualhost_path, project_domain, project_domain))

    with cd('/etc/apache2/sites-available'):
        sudo('a2ensite %s' % project_domain)

Answer 2

def install_site():
    "Add the virtualhost file to apache"
    require('release', provided_by=[deploy, setup])

    with cd('%(path)s/releases/%(release)s/%(release)s' % env):
        sudo('cp %(project_name)s/%(virtualhost_path)s/%(project_domain)s '
                 '/etc/apache2/sites-available/%(project_domain)s' % env)
    with cd('/etc/apache2/sites-available'):
         sudo('a2ensite %(project_domain)s' % env) 

Answer 3

problem fixed, noticing something with the "hg archive .." command, it zips/tars the repo 2 levels deep

local('hg archive --type=tgz %(release)s.tar.gz' % {'release': env.release})

results in 20100418105144.tar.gz which when u open is structured like this:

20100418105144.tar.gz
/20100418105144
/repo

anybody know how i can solve this?
