Question

Sequelize（http://docs.sequelizejs.com/）是我在node.js中使用sqlite几次的orm。是否可以在React Native中使用它。

Answer 1

是的，这是在控制器中使用它的一个例子

var db = require('../db');

module.exports = {
 messages: {
    get: function (req, res) {
      db.Message.findAll({include: [db.User]})
        .then(function(messages) {
          res.json(messages);
        });
    },
    post: function (req, res) {
      db.User.findOrCreate({where: {username: req.body.username}})
        // findOrCreate returns multiple resutls in an array
        // use spread to assign the array to function arguments
        .spread(function(user, created) {
          db.Message.create({
            userid: user.get('id'),
            text: req.body.message,
            roomname: req.body.roomname
          }).then(function(message) {
            res.sendStatus(201);
          });
        });
    }
  },

  users: {
    get: function (req, res) {
      db.User.findAll()
        .then(function(users) {
          res.json(users);
        });
    },
    post: function (req, res) {
      db.User.findOrCreate({where: {username: req.body.username}})
        // findOrCreate returns multiple resutls in an array
        // use spread to assign the array to function arguments
        .spread(function(user, created) {
          res.sendStatus(created ? 201 : 200);
        });
    }
  }
};

var controller = require('./controllers');
var router = require('express').Router();

//Connect controller methods to their corresponding routes
router.get('/messages', controller.messages.get);

router.post('/messages', controller.messages.post);

router.get('/users', controller.users.get);

router.post('/users', controller.users.post);


module.exports = router;

可以在React原生中使用Sequelize吗？
