在belongsTo关系中获取完整的json结构

Question

我试图通过创建belongsTo关系来设置Loopback中的基本模型关系。

我有两个型号定义如下：

Contract.json

{ 
    "name": "Contract", 
    "base": "PersistedModel", 
    "idInjection": false, 
    "options": { 
    "validateUpsert": true 
    }, 
    "mssql": { 
    "schema": "dbo", 
    "table": "Contract" 
    }, 
    "properties": { 
    "contractid": { 
     // some property stuff 
    }, 
    "validations": [], 
    "relations": { 
    "employee": { 
     "type": "belongsTo", 
     "model": "Employee", 
     "foreignKey": "" 
    } 
    }, 
    "acls": [], 
    "methods": [] 
} 

Employee.json

{ 
    "name": "Employee", 
    "base": "PersistedModel", 
    "idInjection": false, 
    "options": { 
    "validateUpsert": true 
    }, 
    "mssql": { 
    "schema": "dbo", 
    "table": "Employee" 
    }, 
    "properties": { 
    "employeeid": { 
     // some property definitions... 
    } 
    }, 
    "validations": [], 
    "relations": { 
    "contracts": { 
     "type": "hasMany", 
     "model": "Contract", 
     "foreignKey": "" 
    } 
    }, 
    "acls": [], 
    "methods": [] 
} 

当我做一个Contract一个GET请求，以此specfic id我得到结果：

调用：/api/Contracts/55

{ 
    "contractid": 55, 
    "employeeId": 83 
} 

目前为止还不错。但是，当我做了GET要求上Contract，也得到Employee的I希望得到像这样的输出继电器：

呼叫：/api/Contracts/55/employee

{ 
    "contractid": 55, 
    "employee": { 
     "employeeid": 83 
    } 
} 

但是，相反，我只得到没有Employee对象的Contract：

{ 
    "employeeid": 83 
} 

这是为什么？

我做错了什么？还是我有错误的期望？

你可以做/api/Contracts/55?filter[include]=employee

或：

/api/Contracts/55?filter={"include":"employee"} 

您可以设置合同模式默认范围加入了 “范围” 部分包括员工的对象：

"scope": { 
    "include": "employee" 
    }
