Django迁移到新数据库 [英] Django Migrating to a new Database

问题描述

我刚刚加入了一个使用Django的项目，并试图初始化我自己的开发服务器。当我尝试这样做时，我的一个应用程序的迁移失败。这个应用程序的一个模型有一个sorl.thumbnail.ImageField，添加一个标志。尝试迁移时，我会收到以下错误消息：

 致命错误 - 以下SQL查询失败：ALTER TABLEaccounts_account ADD CONSTRAINTlogo_id_refs_file_ptr_id_7c3d1997FOREIGN KEY（logo_id）参考filer_image（file_ptr_id）DEFERRABLE INITIALLY DEFERRED; 
错误是：关系filer_image不存在
  

我不知道什么问题可能是，显然在创建生产数据库或后续的迁移中没有问题。

我相信我已经正确安装了sorl-thumbnail及其所有的依赖项

您的帮助将会非常apperciated。

解决方案

将Johndt6提供的答案从未来的搜索能力的这个答案中拉出来。

解决方案是添加 filer 到 INSTALLED_APPS 元组。

I just joined a project using Django, and am attempting to initialize my own development server. When I attempt to do so, the migration fails for one of my apps. A model for this app has a sorl.thumbnail.ImageField, to add a logo. When the migration is attempted, I get the following error message:

FATAL ERROR - The following SQL query failed: ALTER TABLE "accounts_account" ADD CONSTRAINT "logo_id_refs_file_ptr_id_7c3d1997" FOREIGN KEY ("logo_id") REFERENCES "filer_image" ("file_ptr_id") DEFERRABLE INITIALLY DEFERRED;
The error was: relation "filer_image" does not exist

I'm not sure what the problem could be, as apparently there was no problem in creating the production database or subsequent migrations.

I believe I have correctly installed sorl-thumbnail, and all of its dependencies.

Your help would be much apperciated.

解决方案

I'm pulling the answer provided by Johndt6 from a comment to this answer for future search-ability.

The solution is to add filer to the INSTALLED_APPS tuple.
