Question

我想获取所有字段而不写表的所有字段名称。如何使用*来从表中获取所有字段？

This is UserController function to fetch all the rows with all fields of table.

user.findAll({
        attributes: ['name','email','mobile','dob','address','image','is_active'],
        where:{
            is_active:'1',
            name:{$like:'%%'}
        },
        limit:10
    }).then(function(users,fields){
        console.log(users);
        res.send({error:false,message:'users list',data:users});
    }).catch(function(err){
        console.log('Oops! something went wrong, : ', err);
    });

This is model code and define some property of model.

var sequalize = require('../../config/db_config');

const User = sequalize.define('user',{},{
    timestamps: false,
    paranoid: true,
    underscored: true,
    freezeTableName: true,
    tableName: 'user',
    createdAt:'created_on',
    updatedAt:'updated_on'
});

User.sync({force:false}).then(() => {
    console.log('Table is created!');    
}).catch(err => {
    console.log('An error occur when table is created!');
});
module.exports = User;

请帮助我了解如何通过控制器中的写入属性来获取所有字段。

Answer 1

只需在查询中省略属性键，所有字段都将返回。

user.findAll({
  where:{
    is_active:'1',
    name:{$like:'%%'}
  },
  limit:10
}).then(function(users){
  console.log(users);
  res.send({error:false,message:'users list',data:users});
}).catch(function(err){
  console.log('Oops! something went wrong, : ', err);
});

编辑：如果您指定表格中的字段，最好在模型定义中。像这样：http://docs.sequelizejs.com/manual/tutorial/models-definition.html

否则，您必须在每个查找操作中指定属性键。

@yBrodsky是对的。你也应该像这样制作模型。它可以知道在没有属性时选择的字段。

const User = sequalize.define('user',{},{
    timestamps: false,
    paranoid: true,
    underscored: true,
    freezeTableName: true,
    tableName: 'user',
    createdAt:'created_on',
    updatedAt:'updated_on'
});

到这个

var sequalize = require（＆＃39; ../../ config / db_config＆＃39;）;

const User = sequalize.define('user',{
 name: {type: Sequelize.STRING},
  email: {type: Sequelize.STRING},
  mobile: {type: Sequelize.INTEGER},
  dob: {type: Sequelize.DATE}
address: {type: Sequelize.STRING},
  image: {type: Sequelize.INTEGER},
  is_active: {type: Sequelize.BOOLEAN }


},{
    timestamps: false,
    paranoid: true,
    underscored: true,
    freezeTableName: true,
    tableName: 'user',
    createdAt:'created_on',
    updatedAt:'updated_on'
});

只需从模型中删除属性，即可提取所有列
