How to adding default value to Sequelize model with NodeJS?-CodePudding

i have created a controller that to adding new value into the database, but now i do not know how to set up the default value into Sequelize. Let me demonstrate my code below

Model User:

module.exports = (sequelize, Sequelize) => {
  const User = sequelize.define("user", {
    user_id: {
      type: Sequelize.STRING,
      autoIncrement: true,
      primaryKey: true,
    },
    username: {
      type: Sequelize.STRING,
    },
    password: {
      type: Sequelize.STRING,
    },
    full_name: {
      type: Sequelize.STRING,
    },
    email: {
      type: Sequelize.STRING,
    },
    role_id: {
      type: Sequelize.STRING,
    },
    is_active: {
      type: Sequelize.BOOLEAN,
    },
    created_date: {
      type: Sequelize.DATE,
    },
    created_by: {
      type: Sequelize.STRING,
    },
    updated_date: {
      type: Sequelize.DATE,
    },
    updated_by: {
      type: Sequelize.STRING,
    },
  });

  return User;
};

Model Role:

module.exports = (sequelize, Sequelize) => {
  const Role = sequelize.define("role", {
    role_id: {
      type: Sequelize.STRING,
      autoIncrement: true,
      primaryKey: true,
    },
    role_name: {
      type: Sequelize.STRING,
    },
    is_active: {
      type: Sequelize.BOOLEAN,
    },
    created_date: {
      type: Sequelize.DATE,
    },
    created_by: {
      type: Sequelize.STRING,
    },
    updated_date: {
      type: Sequelize.DATE,
    },
    updated_by: {
      type: Sequelize.STRING,
    },
  });

  return Role;
};

Controller User:

const db = require("../models");
const User = db.users;

exports.create = (req, res) => {
    // Validate request
    if (!req.body.username) {
      res.status(400).send({
        message: "Content can not be empty!"
      });
      return;
    }
  
    // Create a Tutorial
    const user = {
        username: req.body.username,
        password: req.body.password,
        full_name: req.body.full_name,
        email: req.body.email,
        role_id: req.body.role_id,
        is_active: req.body.is_active,
        created_date: req.body.created_date,
        created_by: req.body.created_by,
        updated_date: req.body.updated_date,
        updated_by: req.body.updated_by,
    };
  
    // Save Tutorial in the database
    User.create(user)
      .then(data => {
        res.send(data);
      })
      .catch(err => {
        res.status(500).send({
          message:
            err.message || "Some error occurred while creating new User."
        });
      });
  };

Now i need help to add the default value that every value MUST BE Role is USER and is_active = 1. If you have any ideas please help me or give my some suggestions so i can complete this problem easier. And, i hope you can upvote this post. Thank you

CodePudding user response：

You can define the default value at the database level in your migration file. Or, you can also define at sequelize level in your model definition itself.

module.exports = (sequelize, Sequelize) => {
  const User = sequelize.define("user", {
    user_id: {
      type: Sequelize.STRING,
      autoIncrement: true,
      primaryKey: true,
    },
role_name: {
      type: Sequelize.STRING,
      defaultValue: 'USER'
    },
    is_active: {
      type: Sequelize.BOOLEAN,
      defaultValue: true
    }
    });

  return User;
};
