我正在使用Redmine 2.0.3。我开发了一个名为cg_process的自定义插件。
在目录plugins / cg_process / app / models /中，有一个名为“ProjectInfo.rb”的模型文件。
当我使用插件时，Redmine找不到该模型。
它出现以下错误：

如果我将模型文件ProjectInfo.rb从插件目录（plugins / cg_process / app / models /）复制到核心目录（app / models），一切运行良好。
暂时我在capistrano部署文件中进行了修复，以便将模型文件复制到核心目录。但这只是一种解决方法。我想找到一个标准的解决方案。
我无法理解为什么Redmine无法在插件目录中找到该模型。
可能我错过了什么，但我无法弄清楚是什么。
任何帮助？
答案 0 :(得分：0)
我希望您尝试创建一个redmine插件模型。所以运行
rails generate redmine_plugin_model <plugin_name> <model_name>
那是
rails generate redmine_plugin_model cg_process project_info
然后编辑迁移文件并添加字段，运行
rake redmine:plugins:migrate
