重复使用相同字段时的架构错误

Question

我有两个使用相同字段的独立架构。我试图创建schemaComponents，以便我可以在一个位置更新两个模式，但是我得到一个错误Error: Invalid definition for school.$ field。当我使用它。我不确定我在这里做错了什么，我在这个允许的印象之下。

路径：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'}, 
     ] 
    } 
    } 
}; 

路径：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); 

路径：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

您定义SchemaComponent作为一个简单的对象而不是作为SimpleSchema对象。要重用你schools定义做：

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'}, 
     ] 
    } 
    } 
}); 

然后，你可以这样做：

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