werkzeug.script
|
|
~~~~~~~~~~~~~~~
|
|
|
|
.. admonition:: Deprecated Functionality
|
|
|
|
``werkzeug.script`` is deprecated without replacement functionality.
|
|
Python's command line support improved greatly with :mod:`argparse`
|
|
and a bunch of alternative modules.
|
|
|
|
Most of the time you have recurring tasks while writing an application
|
|
such as starting up an interactive python interpreter with some prefilled
|
|
imports, starting the development server, initializing the database or
|
|
something similar.
|
|
|
|
For that purpose werkzeug provides the `werkzeug.script` module which
|
|
helps you writing such scripts.
|
|
|
|
|
|
Basic Usage
|
|
-----------
|
|
|
|
The following snippet is roughly the same in every werkzeug script::
|
|
|
|
#!/usr/bin/env python
|
|
# -*- coding: utf-8 -*-
|
|
from werkzeug import script
|
|
|
|
# actions go here
|
|
|
|
if __name__ == '__main__':
|
|
script.run()
|
|
|
|
Starting this script now does nothing because no actions are defined.
|
|
An action is a function in the same module starting with ``"action_"``
|
|
which takes a number of arguments where every argument has a default. The
|
|
type of the default value specifies the type of the argument.
|
|
|
|
Arguments can then be passed by position or using ``--name=value`` from
|
|
the shell.
|
|
|
|
Because a runserver and shell command is pretty common there are two
|
|
factory functions that create such commands::
|
|
|
|
def make_app():
|
|
from yourapplication import YourApplication
|
|
return YourApplication(...)
|
|
|
|
action_runserver = script.make_runserver(make_app, use_reloader=True)
|
|
action_shell = script.make_shell(lambda: {'app': make_app()})
|
|
|
|
|
|
Using The Scripts
|
|
-----------------
|
|
|
|
The script from above can be used like this from the shell now:
|
|
|
|
.. sourcecode:: text
|
|
|
|
$ ./manage.py --help
|
|
$ ./manage.py runserver localhost 8080 --debugger --no-reloader
|
|
$ ./manage.py runserver -p 4000
|
|
$ ./manage.py shell
|
|
|
|
As you can see it's possible to pass parameters as positional arguments
|
|
or as named parameters, pretty much like Python function calls.
