In Fabric, how can I execute tasks from another python file?

fabric, python

Solution

Change `execute('start')` to `execute(start)`.

I didn't find out why pass a taskname to execute did not work, but there is a workaround:

import fabfile
execute(getattr(fabfile, 'start'))

Update： After reading a bit code and doing some test of fabric, I think `execute('task_name')` can only be used when fabric tasks are loaded. By default you can use it in the fabfile.py like this:

@task
def task1():
    #do task1

@task
def task2():
    #do task2

@task
def task3():
    #do task1 and task2
    execute('task1')
    execute('task2')

Then you can use `fab task3` to execute `task1` and `task2` together. But till now, I am still using fabric a tool.

Update again :-)

Then I read a bit code of fabric and found that use fabric as a tool will call `fabric.main.main` which invokes `fabric.main.load_fabfile` to load tasks from the fabfile.

Since you use `python main.py` to run your script, fab tasks are not loaded even if you imported fabfile. So I add a bit code to you `main.py`:

docstring, callables, default = load_fabfile('fabfile.py')
state.commands.update(callables)

And now, `execute('start')` works exactly as you wanted.

Problem

I have a fabfile (fabfile.py) with some tasks declared: ``` # fabfile.py from fabric.api import * @task def start(): # code @task def stop(): # code ``` Then when I try to call any of those tasks using the execute function from fabric like this: ``` # main.py from fabric.api import execute from fabfile import * # I don't really know if this is necessary # or how should it be done def main(): execute('start') ``` It raises this error: ``` Fatal error: None is not callable or a valid task name ``` My intention is to make a kind of wrapper for some tasks specified in that fabfile that can be called with different arguments, and the task to perform must be taken from the arguments when you make a call to this main program, so I can't explicitly call the function, but use the task names. How would this be done? Maybe I'm misunderstanding how fabric is supposed to work? Thank you
