django-subcommander 0.1

使用django-subcommander编写具有子命令的Django管理命令，每个子命令都可以有自己独特的选项、帮助和其他通常的命令行为。子命令只是普通的Django BaseCommand 子类，因此无需学习太多新知识。以下是一个顶级命令示例；您可以将此放入应用程序的 management.commands.desserts 模块中

from django_subcommander import SubcommandDispatcher


class Command(SubcommandDispatcher):
    """The top-level "dessert" command which has several subcommands"""

    help = 'Eat, top, and do various things with desserts.'
    args = '<subcommand> [more arguments and options]'

    def _subcommand(self, name):
        """
        Return a management command that implements the subcommand of the
        given name.
        """
        if name == 'eat':
            return EatCommand()
        elif name == 'top':
            ,,,


class EatCommand(BaseCommand):
    # You could put this in another module or wherever you want.
    help = 'Eat a dessert.'
    args = '[number of bites]'

    # Add options here with make_option(), in the usual way.

    def handle(self, *args, **options):
        ...

要调用5口吃甜点的子命令……

./manage.py dessert eat 5

要查看 eat 子命令的帮助……

./manage.py dessert eat --help

要查看顶级命令的帮助……

./manage.py dessert --help

如果实现了 _subcommand_names，顶级命令的帮助将列出其子命令

class Command(SubcommandDispatcher):
    ...

    def _subcommand(self, name):
        ...

    def _subcommand_names(self):
        """Return a list of the names of all the subcommands."""
        return ['eat', 'top']

然后， ./manage.py dessert --help 将显示类似以下内容

Usage: ...

Options:
  ...

Subcommands:
  eat [number of bites]
  top <topping> [more toppings]
