无法使用Sequelize将Schema（postgresql）中的模型关联起来
我正在尝试使用Postgresql（9.3）的Sequelize（1.7）并尝试使用模式。 我在数据库中创build了外部模式，但在我的模型中使用它们。 当我试图做模型关联时，Sequelize抱怨这个关系不存在。 当我重新定义模型使用PostgreSQL的默认“公共”模式时，它工作正常。
这里是testing用例的模型定义和代码
var Promise = require("bluebird"); var Sequelize = require("sequelize"); var _ = require('lodash-node'); var schemaName ="test_schema"; var sequelize = new Sequelize( c.database,c.username, c.password,{dialect :'postgres', port:'5432',schema:schemaName}); var User =sequelize.define('User',{ id:{ type: Sequelize.INTEGER,primaryKey:true, autoIncrement:true}, name:{type:Sequelize.TEXT,allowNull:false}, nick_name:{type:Sequelize.TEXT,allowNull:true}, date_of_joining:{type:Sequelize.DATE,allowNull:false,defaultValue:Sequelize.NOW} }, { tableName:"user", underscored:true, timestamps:false } ); var Task = sequelize.define( 'Task', { id:{ type: Sequelize.INTEGER,primaryKey:true, autoIncrement:true}, name:{type:Sequelize.TEXT,allowNull:false}, begin_time:{type:Sequelize.DATE,allowNull:false,defaultValue:Sequelize.NOW}, end_time:{type:Sequelize.DATE,allowNull:true} }, { tableName:"task", underscored:true, timestamps:false } ); User.schema(schemaName); Task.schema(schemaName); User.hasMany( Task, {as:"Tasks"}); sequelize.sync( {force:true}, {logging:console.log}) .then( function( args ){ var users =[ {name:"Abraham Milbard"}, {name:"Jimmy Quake"}, {name:"John Amayo"} ]; var tasks =[ {name:"Bring 100 apples by today evening"}, {name:"Do the dishes"}, {name:"Watch soap and weep"}, {name:"Bitch about your miserable life"} ]; User.create( users[0]) .success( function( usr ){ var chainer = new Sequelize.Utils.QueryChainer; var t1 = Task.build( tasks[0 ]), t2 = Task.build( tasks[1]); chainer.add(t1.save() ); chainer.add(t2.save() ); chainer.runSerially({ skipOnError:true}) .success( function( results ){ var tsk1 = results[0]; var tsk2 = results[1]; usr.setTasks([tsk1,tsk2]).success( function(assocTasks){ }); }).error( function( err ){ console.log("Could not add tasks to user"+err); }); }).error( function( err ){ console.log("Could not create user "); }); }); 如果您执行此代码，则报告的错误是：
error: relation "task" does not exist
生成的查询是：
Executing (default): SELECT * FROM "test_schema"."task" WHERE "test_schema"."task"."user_id"=1; Executing (default): UPDATE "task" SET "user_id"=1 WHERE "id" IN (1,2) RETURNING *
可以清楚地看到，由于模式前缀“test_schema”缺失，UPDATE语句失败。 换句话说，该工具发出以下查询：
UPDATE "test_schema"."task" SET "user_id"=1 WHERE "id" IN (1,2) RETURNING *
它会工作得很好。 任何人都可以提供任何解决方法/见解？
看起来你正在运行一个旧版本的sequelize.js
QueryChainer从一个sequelize版本中被删除，这是我第一次尝试运行你的例子时碰到的。 我还发现一个github问题，引用了一个类似的问题，并针对该问题进行了合并修复。
小错误修复 – 使用创build而不是构build
这里是更新的代码：
var Sequelize = require("sequelize"); var _ = require('lodash-node'); var schemaName ="test_schema"; var sequelize = new Sequelize( 'database', 'username', 'password', {dialect :'postgres', port:'5432',schema:schemaName}); var User =sequelize.define('User',{ id:{ type: Sequelize.INTEGER,primaryKey:true, autoIncrement:true}, name:{type:Sequelize.TEXT,allowNull:false}, nick_name:{type:Sequelize.TEXT,allowNull:true}, date_of_joining: {type:Sequelize.DATE,allowNull:false,defaultValue:Sequelize.NOW} }, { tableName:"user", underscored:true, timestamps:false } ); var Task = sequelize.define( 'Task', { id:{ type: Sequelize.INTEGER,primaryKey:true, autoIncrement:true}, name:{type:Sequelize.TEXT,allowNull:false}, begin_time:{type:Sequelize.DATE,allowNull:false,defaultValue:Sequelize.NOW}, end_time:{type:Sequelize.DATE,allowNull:true} }, { tableName:"task", underscored:true, timestamps:false } ); User.schema(schemaName); Task.schema(schemaName); User.hasMany( Task, {as:"Tasks"}); sequelize.sync( {force:true}, {logging:console.log}) .then( function( args ){ var users =[ {name:"Abraham Milbard"}, {name:"Jimmy Quake"}, {name:"John Amayo"} ]; var tasks =[ {name:"Bring 100 apples by today evening"}, {name:"Do the dishes"}, {name:"Watch soap and weep"}, {name:"Bitch about your miserable life"} ]; User.create( users[0]) .then( function( usr ){ var tsk1; Task.create( tasks[0] ) .then( function( task ) { tsk1 = task; return Task.create( tasks[1] ); } ) .then( function( tsk2 ) { return usr.setTasks([tsk1,tsk2] ); } ) .then( function ( assocTasks ) { } ) .catch( function( err ) { console.log( err ); }); }); });
这里是输出：
