我需要自动伪造Django 1.9迁移。是否有可以放入迁移文件的标志,该文件将自动伪造,而不必登录到多个服务器并运行。
迁移布局就像这样
asset(str_replace(app_path(),'',$img->path))
我知道我可以做./manage.py my_app migrate 0002 --fake,但迁移0002可以自动伪造吗?我需要运行的是./manage.py my_app migrate

Django 1.8+不会自动伪造迁移。您需要使用--fake-initial
选项告诉Django伪造初始迁移。
./manage.py migrate --fake-initial
然后,您可以在initial = True
迁移类上设置0002
,告诉Django这是初始迁移。
class Migration(migrations.Migration):
initial = True
dependencies = [('migrations', '0001_initial')]
有关详细信息,请参阅initial migrations上的文档。

在具有现有迁移的实时项目中,从Django的本机用户模型迁移到自定义模型时,我需要做同样的事情。我通过覆盖apply / unapply方法来实现它:
