Django manage.py --no-input.是还是不是？

Question

我在文档中找不到这个.当我运行时python manage.py collecstatic --no-input它是否意味着它会对流程中弹出的任何提示回答"是"？同样的python manage.py migrate --no-input.

Answer 1

您可以随时查看django源代码.你知道,它是开源的.

对于collectstatic:

    message.append(
        'Are you sure you want to do this?\n\n'
        "Type 'yes' to continue, or 'no' to cancel: "
    )

    if self.interactive and input(''.join(message)) != 'yes':
        raise CommandError("Collecting static files cancelled.")

所以对于收集静态,如果你设置--no-input它将设置interactive为False,如上所述,将回答yes你的问题.

对于迁移,由于django信令,它更加棘手.该migrate管理本身并没有问任何问题,但其他安装的应用程序可以钩到pre_migrate_signal或post_migrate_signal并以自己的方式来处理的交互性.我所知道的最常见的是contenttypes

对于contenttypes,--no-input回答"否",如"否,请不要删除任何陈旧的内容类型":

        if interactive:
            content_type_display = '\n'.join(
                '    %s | %s' % (ct.app_label, ct.model)
                for ct in to_remove
            )
            ok_to_delete = input("""The following content types are stale and need to be deleted:

%s

Any objects related to these content types by a foreign key will also
be deleted. Are you sure you want to delete these content types?
If you're unsure, answer 'no'.

    Type 'yes' to continue, or 'no' to cancel: """ % content_type_display)
        else:
            ok_to_delete = False
