Console / shell script runs twice when using pyramid.paster and bootstrapping

You’ve just created your new, exceptional shell script to maintain your pyramid application from the console, when you discover that everything runs twice. Usually not a very good idea, but .. why?

The issue is probably that you’re running pyramid with the scan option, which requires all modules in the path of your pyramid application to be imported. This will also import your console script, and if you haven’t placed everything into a function and added a check to see if the script has been invoked directly, you’re fscked!

The easy way out is to put your code into a function:

def main():
    from pyramid.paster import bootstrap
    env = bootstrap('../../development.ini')


if __name__ == '__main__':  

The last if-test check if this is the main file that has been invoked, and if true, calls main and launches your script. This should hopefully solve the issue!
