Sails.js - One to Many mapping
提问by Samuel Ptheitroadier
Is there any way to do relation mapping between models in Sails.js?
有没有办法在 Sails.js 中的模型之间进行关系映射？
Here is what I would like:
这是我想要的：
Video.js:
视频.js：
module.exports = {
attributes: {
filename: 'STRING',
length: 'INTEGER',
watchCount: 'INTEGER',
extension: 'STRING'
user: // I wan to reference to my User.js model
}
};
And in my User.js:
在我的 User.js 中：
module.exports = {
attributes: {
username: {
type: 'email',
required: true
},
password: 'STRING',
videos: // I would like to have an array of videos after querying a user
}
};

You can use associations in sailsJs now by using the v0.10 branch
https://stackoverflow.com/a/21822843/1585332
The mapping would be something like this..
您现在可以通过使用 v0.10 分支在sailsJs 中使用关联
https://stackoverflow.com/a/21822843/1585332
映射将是这样的..
Video.js
视频.js
module.exports = {
attributes: {
filename: 'STRING',
length: 'INTEGER',
watchCount: 'INTEGER',
extension: 'STRING'
user:{
model: "user"
}
}
};
User.js
用户.js
module.exports = {
attributes: {
username: {
type: 'email',
required: true
},
password: 'STRING',
videos:{
collection: "video",
via: "user"
},
}
};

Sails.js doesn't support association yet, but they're working on it: https://github.com/balderdashy/sails/issues/124#issuecomment-21690561
Sails.js 尚不支持关联，但他们正在努力：https: //github.com/balderdashy/sails/issues/124#issuecomment-21690561

For now I would just reference ID's and/or use the .query() method.
现在我只会引用 ID 和/或使用 .query() 方法。
