javascript - SailsJS 一对多自 v0.11.0 起不再工作

Question

我目前正在开发 SailsJS 应用程序。我开始使用 0.10.5 版本，并实现了许多模型之间的继承。一切工作正常。

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

现在，我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 
          ^

这是我的模型:

/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工作了(提醒:它在 v 0.10.5 中运行良好)。

感谢您的阅读，祝你有美好的一天:)

您的所有模型都应位于 api/models 中。无处。如果你只是遵循惯例，一切都会成功。

如果您有从中扩展的“基本”模型，如果您不希望在数据库中为它们创建表，只需将它们完全放在 api/ 之外。
