如何防止服务的变化
我正在使用Mongoose的Feathers.js,我想创建一个服务无法更改的字段。
// account-model.js - A mongoose model
//
// See .html
// for more of what you can do here.
const mongoose = require('mongoose');
require('mongoose-type-email');
module.exports = function(app) {
const mongooseClient = app.get('mongooseClient');
const recovery = new mongooseClient.Schema({
token: { type: String, required: true }
}, {
timestamps: true
});
const account = new mongooseClient.Schema({
firstName: { type: String, required: true },
surname: { type: String, require: true },
phone: { type: String, require: true },
email: { type: mongoose.SchemaTypes.Email, required: true, unique: true },
birth: { type: Date, required: true },
gender: { type: String, required: true },
country: { type: String, required: true },
address: { type: String, required: true },
address2: { type: String, required: false },
city: { type: String, required: true },
postcode: { type: String, required: true },
password: { type: String, required: true },
status: { type: String, required true }
}, {
timestamps: true
});
return mongooseClient.model('account', account);
};
没有人可以在/account/<id>
发布帖子并更改字段status
。该字段只能在内部更改。当一些批准服务请求。
我该如何实现这种行为?
回答如下:这是Feathers hooks的完美用例。当从外部访问时,在service method中调用params.provider将被设置,以便您可以检查它并从data
中删除该字段,如果它是:
module.exports = function() {
return async context => {
if(context.params.provider) {
delete context.data.status;
}
}
}
这个钩子将是before
,create
和update
方法的patch
钩子。
