Re: [Fab-user] No hosts found - Fabric execution model: works only on relative imports?

[Carlos García]

Hi Alec,

the examples given doesn’t work. Maybe you’re missing something.

env should be imported from fabric.api, if not, Python fails with NameError: name 'env' is not defined

Also, the Python path should include foo/and can/, so you need to call a python executable from the project root (Or add ROOT_DIRECTORY to the python path with sys.path.append(ROOT_DIRECTORY)). For example:

## foo/__init__.py
import sys 
import os
sys.path.append(os.path.abspath('.'))
from fabric.api import execute
from can.haz import funtimes

domain = 'localhost'
env.user = 'bar'
env.password = 'foo'
env.hosts = [domain]

execute(funtimes)

And you execute it with: python foo/__init__.py. And this works.

Using Fabric outside a fabfile. `fabric.api.execute` on relative imported functions works.

Importing other installed modules fails with "No hosts found. Please specify (single) host string for connection:"

To illustrate, this works:

## foo/__init__.py

from fabric.api import execute

from bar import funtimes

domain = 'localhost'
env.user = 'bar'
env.password = 'foo'
env.hosts = [domain]

execute(funtimes)

## foo/bar.py

from fabric.api import run

def funtimes(): run('hello funtimes')

Whilst this fails:

## foo/__init__.py

from fabric.api import execute

from can.haz import funtimes

domain = 'localhost'
env.user = 'bar'
env.password = 'foo'
env.hosts = [domain]

execute(funtimes)

## can/haz.py

from fabric.api import run

def funtimes(): run('hello funtimes')

# also tried
def funtimes2(env):
    fabric.api.env = env

    run('hello funtimes2')
