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:)
最佳答案
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。
