SailsJS 一对多从 v0.11.0 开始不工作

Question

我目前正在开发 SailsJS 应用程序。我开始使用 0.10.5 版本并实现了许多模型，它们之间具有继承性。一切正常。

今天，我决定将我的 SailsJS 项目更新到版本 0.11.0。我读过最简单的方法是用 npm 更新所有 SailsJS 文件，然后创建一个新项目，最后将所有模型、控制器等复制到新创建的项目中。这是我到目前为止所做的。

我现在每次尝试提升项目时都会遇到问题：

/usr/local/lib/node_modules/sails/node_modules/waterline/node_modules/waterline-schema/lib/waterline-schema/foreignKeys.js:82
    throw new Error('Trying to access a collection ' + collection + ' that is 
          ^

有我的模型:

/api/services/OrthancObject.js

module.exports = {
    attributes:
    {
        ID:
        {
            type: 'STRING',
            primaryKey: true,
            required: true
        },
        Type:
        {
            type: 'STRING',
            required: true
        },
        MainDicomTags:
        {
            type: 'JSON',
            required: true
        }
    }
}

/api/services/OrthancMutableObject.js

var OrthancObject = require('./OrthancObject.js');
module.exports = _.merge(_.cloneDeep(OrthancObject),
{
    attributes:
    {
        IsStable:
        {
            type: 'BOOLEAN',
            required: true
        },
        LastUpdate:
        {
            type: 'DATETIME',
            required: true
        }
    }
});

/api/models/Patient.js

var OrthancMutableObject = require('../services/OrthancMutableObject.js');
    module.exports = _.merge(_.cloneDeep(OrthancMutableObject),
    {
        attributes:
        {
            Studies:
            {
                collection: 'Study',
                via: 'ParentPatient',
                required: true
            }
        }
    });

/api/models/Study.js

var OrthancMutableObject = require('../services/OrthancMutableObject.js');
module.exports = _.merge(_.cloneDeep(OrthancMutableObject),
{
    attributes:
    {
        ParentPatient:
        {
            model: 'Patient',
            required: true
        },
        Series:
        {
            collection: 'Series',
            via: 'ParentStudy',
            required: true
        }
    }
});

/api/models/Series.js

var OrthancMutableObject = require('../services/OrthancMutableObject.js');
module.exports = _.merge(_.cloneDeep(OrthancMutableObject),
{
    attributes:
    {
        ExpectedNumberOfInstances:
        {
            type: 'INTEGER'
        },
        Instances:
        {
            collection: 'Instance',
            via: 'ParentSeries',
            required: true
        },
        ParentStudy:
        {
            model: 'Study',
            required: true
        },
        Status:
        {
            type: 'STRING'
        }
    }
});

/api/models/Instance.js

var OrthancObject = require('../services/OrthancObject.js');
module.exports = _.merge(_.cloneDeep(OrthancObject),
{
    attributes:
    {
        FileSize:
        {
            type: 'INTEGER',
            required: true
        },
        FileUuid:
        {
            type: 'INTEGER',
            required: true
        },
        IndexInSeries:
        {
            type: 'INTEGER',
            required: true
        },
        ParentSeries:
        {
            model: 'Series'
        }
    }
});

你能解释一下我做错了什么吗？我不明白为什么它不再起作用（提醒：它在 v 0.10.5 中运行良好）。

感谢阅读，祝你有美好的一天:)

Answer 1

好的伙计们。我找到了解决方案：我不得不将所有基本模型从 /api/services 移动到 /api/base。现在它有效，但我真的不知道为什么。也许自从上次更新以来，SailsJS 不再在 /api/services 中发挥它的魔力了。

Answer 2

您的所有模型都应该在 api/models 中。无处。如果你只是按照惯例，一切都会成功。

如果您有 "base" 个模型作为扩展源，如果您不想在数据库中为它们创建表，只需将它们放在 api/ 之外。
