Hello,
We are using fabric for development as well as deployment and I'm wondering
how people are doing command like this.
@task
def load_fixtures():
"""Load initial data."""
run("venv/bin/python data/fixtures.py")
This code should work for both the developer machine (ie: run local) and
the deployment machine (ie: use run)
So far what I have done is something like
@task
def install_db(command=local):
"""@onetime install of the database"""
with prefix("source venv/bin/activate"):
command("python manage.py syncdb --migrate")
However that's a bit of a problem as I can't call that command from fab
just from other fabric scripts.

Hello all,
I'm trying to build a web app around a few fabric scripts, and I need to
supply a dynamic list of hosts to the scripts. I saw the -H switch, but it
apparently only works when env.hosts is defined in the fabric script. I
also looked at command-line kwargs for methods, but the methods won't even
be executed without env.hosts being defined. Can someone point me in the
right direction?
Thanks,

The way I deploy to localhost now is to run ssh on my local machine. That
way I can access my local machine "remotely" in fabric scripts. On my mac
laptop, here is how I enabled remote logins via ssh. Go to System
Preferences, choose Sharing. Select Remote login. That's it. This
approach seems to fit into the fabric model well.
I used to deploy locally by following the advice at
http://stackoverflow.com/questions/6725244/running-fabric-script-locally.
Basically, I would assign env.run = run or env.run = local, depending on
where I was deploying, perhaps in a task something like (warning: untested
code):
```
env.run = run
@task
def localhost():
env.run = local
@task
def do_something():
env.run('path/to/myscript.py')
```
Then I would do invoke it like:
```
fab local do_something
```
This got smellier when I started rsyncing, since I had to write a
local version and remote version of rsync. Then when I started
using `fabric.api.get`, I realized that I would have to write a API
compatible version of `get` and `put` if I wanted to continue down this
path. That pushed me to find the better way described above.
Hope that helps.
