重複使用相同字段時的架構錯誤

Question

我有兩個使用相同字段的獨立架構。我試圖創建schemaComponents，以便我可以在一個位置更新兩個模式，但是我得到一個錯誤Error: Invalid definition for school.$ field。當我使用它。我不確定我在這裏做錯了什麼，我在這個允許的印象之下。

路徑：SchemaComponents.js

SchemaComponents = { 
    schools: { 
    type: [String], 
    optional: true, 
    autoform: { 
     options: [ 
     {label: "School One", value: 'SchoolOne'}, 
     {label: "School Two", value: 'SchoolTwo'}, 
     {label: "School Three", value: 'SchoolThree'}, 
     ] 
    } 
    } 
}; 

路徑：StudentSchema.js

import from '../components/SchemaComponents.js'; 
StudentSchema = new Mongo.Collection("studentSchema"); 

var Schemas = {}; 

Schemas.StudentSchema = new SimpleSchema({ 
    school: SchemaComponents.schools, 
}); 

StudentSchema.attachSchema(Schemas.StudentSchema); 

路徑：TeacherSchema.js

import from '../components/SchemaComponents.js'; 
TeacherSchema = new Mongo.Collection("teacherSchema"); 

var Schemas = {}; 

Schemas.TeacherSchema = new SimpleSchema({ 
    school: SchemaComponents.schools, 
}); 

TeacherSchema.attachSchema(Schemas.TeacherSchema); 

Answer 1

您定義SchemaComponent作爲一個簡單的對象而不是作爲SimpleSchema對象。要重用你schools定義做：

let schoolsSchema = new SimpleSchema({ 
    schools: { 
    type: [String], 
    optional: true, 
    autoform: { 
     options: [ 
     {label: "School One", value: 'SchoolOne'}, 
     {label: "School Two", value: 'SchoolTwo'}, 
     {label: "School Three", value: 'SchoolThree'}, 
     ] 
    } 
    } 
}); 

然後，你可以這樣做：

Schemas.TeacherSchema = new SimpleSchema({ 
    school: { 
    type: schoolsSchema 
    } 
});
