Question

重新设置我们的azure服务器时，equalise.sync（）方法挂在它刚刚创建的表的SHOW INDEX上。即使该表几乎与刚创建的表相同。

我们的关系'教师'的模型如下：

 'use strict';
module.exports = function(sequelize, DataTypes) {
  var Teacher = sequelize.define('Teacher', {
    email: DataTypes.STRING
   } , {
    classMethods: {
      associate: function(models) {
        // associations can be defined here
      }
    }
  });
  return Teacher;
};

这是来自成功创建的学生关系的代码，继续经过SHOW INDEX并且不会导致脚本挂起：

'use strict';
module.exports = function(sequelize, DataTypes) {
  var Student = sequelize.define('Student', {
    email: DataTypes.STRING
  }, {
    classMethods: {
      associate: function(models) {
        // associations can be defined here
      }
    }
  });
  return Student;
};

这是代码在挂起/崩溃之前所处的位置：

Nodejs Sequelize.sync（）挂在SHOW INDEX上？
