Django 1.8 运行特定迁移

Question

在 django 1.8 中有一种方法可以运行一个特定的迁移并且只进行那个迁移。

不仅针对某个应用程序，还针对该应用程序迁移目录中的特定文件。

编辑为原文：

    Traceback (most recent call last):
  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/home/vagrant/virtualenvs/aku/lib/python3.4/site-packages/django/core/management/__init__.py", line 338, in execute_from_command_line
    utility.execute()
  File "/home/vagrant/virtualenvs/aku/lib/python3.4/site-packages/django/core/management/__init__.py", line 330, in execute
    self.fetch_command(subcommand).run_from_argv(self.argv)
  File "/home/vagrant/virtualenvs/aku/lib/python3.4/site-packages/django/core/management/base.py", line 393, in run_from_argv
    self.execute(*args, **cmd_options)
  File "/home/vagrant/virtualenvs/aku/lib/python3.4/site-packages/django/core/management/base.py", line 444, in execute
    output = self.handle(*args, **options)
  File "/home/vagrant/virtualenvs/aku/lib/python3.4/site-packages/django/core/management/commands/migrate.py", line 146, in handle
    plan = executor.migration_plan(targets)
  File "/home/vagrant/virtualenvs/aku/lib/python3.4/site-packages/django/db/migrations/executor.py", line 50, in migration_plan
    self.loader.graph.node_map[target].children
KeyError: ('wagtailcore', '0001_initial')

Answer 1

您可以告诉 Django 移动到特定的迁移

./manage.py migrate myapp 0005_migration_to_run

但是 Django 会运行每次迁移到（或返回）您选择的迁移。

您可以尝试faking之前的迁移

./manage.py migrate --fake myapp 0004_previous_migration
./manage.py migrate myapp 0005_migration_to_run

然后您可能想要伪装到您开始时的迁移。
