Django：不存在关系

我已经从bitbucket中提取了项目更新并尝试了以下命令'python3 manage.py makemigrations'，'python3 manage.py migrate vehicle'，'python3 manage.py migrate'。但是我收到以下错误。车辆应用程序是新的，它的一些模型使用其他应用程序的外键，这些应用程序之前已经迁移过，并且在数据库中。我尝试了不同的方式，但找不到解决方案。我正在使用django-1.7.4我很欣赏任何建议。Django：不存在关系

请给我们'settings.py'和'INSTALLED_APPS'上'settings.py' –

更新这些信息。请帮助 –

为我所看到的，我尝试它运行迁移之前validade的AdvancedVehicleSearchForm，尝试以django可以首先进行迁移的方式将有关车辆的表单传递给车辆应用程序。我无法帮助您更多地显示您在那里显示的文件。我希望它能以某种方式帮助你

感谢您的提示。我评论过（＃'django.contrib.admin'），因为错误显示它试图验证管理员和相关表单。然后运行python3 manage.py migrate。它像一个魅力。 –
