sails-industrial-factory

Simple model factory for Sails.js with Sequelize inspired by Sails Factory

Installation

    npm install sails-industrial-factory

Usage

Defining factories

Define a factory by giving it a name and an optional model name. The factory name will be the default model name (parent model or the name itself) if model name is not provided.

var factory = require("sails-industrial-factory");
 
factory.define("user")
  .attr("first_name", "First Name")
  .attr("last_name", "Last Name")
  .attr("random_id", function() { return Math.random(); });
 
factory.define("active_user").parent("user")
  .attr("active", true);
 
factory.define("admin_user", Admin).parent("user");

Using factories

//Callback
factory.build("active_user", function(err, active_user) {
  // active_user: non-persistent "active_user" instance
  // {
  //    first_name: "First Name",
  //    last_name: "Last Name",
  //    random_id: <number>,
  //    active: true
  // }
});
 
factory.build("user", {first_name: "Hello", last_name: function() { return "World"; }}, function(err, user) {
  // user: non-persistent "user" instance
  // {
  //    first_name: "Hello",
  //    last_name: "World",
  //    random_id: <number>
  // }
});
 
factory.create("active_user", function(err, active_user) {
  // active_user: sails User model instance
  // {
  //    id: <id>,
  //    first_name: "First Name",
  //    last_name: "Last Name",
  //    random_id: <number>,
  //    active: true,
  //    createdAt: <date>,
  //    updatedAt: <date>
  // }
});
 
//Promise
factory.build("active_user")
  .then(()=> {
  // active_user: non-persistent "active_user" instance
  // {
  //    first_name: "First Name",
  //    last_name: "Last Name",
  //    random_id: <number>,
  //    active: true
  // }
  });
 
factory.build("user", {first_name: "Hello", last_name: function() { return "World"; }})
  .then(()=> {
  // user: non-persistent "user" instance
  // {
  //    first_name: "Hello",
  //    last_name: "World",
  //    random_id: <number>
  // }
  });
 
factory.create("active_user")
  .then(()=> {
  // active_user: sails User model instance
  // {
  //    id: <id>,
  //    first_name: "First Name",
  //    last_name: "Last Name",
  //    random_id: <number>,
  //    active: true,
  //    createdAt: <date>,
  //    updatedAt: <date>
  // }
  });

Auto increment attributes

Attributes can have an auto_increment option. By default, sequence will increment by 1, otherwise it will increment by whatever value the auto_increment option is set to. Counting starts at the initial value given. Sequence is shared among parent and children.

    factory.define("user")
      .attr("id", 0, {auto_increment: true})
      .attr("first_name", "First Name - ", {auto_increment: 5});
 
    factory.define("other_user").parent("user");
 
    factory.build("user", function(user) {
      // user:
      // {
      //    id: 1,
      //    first_name: "First Name - 5",
      //    ...
      // }
    });
 
    factory.create("user", function(user) {
      // user:
      // {
      //    id: 2,
      //    first_name: "First Name - 10",
      //    ...
      // }
    });
 
    factory.build("other_user", function(other_user) {
      // other_user:
      // {
      //    id: 3,
      //    first_name: "First Name - 15",
      //    ...
      // }
    });

Loading factories

Calling .load() without parameter will try to load factory definitions from test/factories folder.

// api/models/User.js
module.exports = {
  attributes: {
    first_name: {
      type: Sequelize.STRING,
      allowNull: false,
    },
    last_name: {
      type: Sequelize.STRING,
      allowNull: false,
    },
    last_name: {
      type: Sequelize.STRING,
      allowNull: false,
    },
    active: {
      type: Sequelize.BOOLEAN,
      allowNull: false,
      defaultValue: false,
    },
  },
};
 
 
// test/factories/User.js
module.exports = function(factory) {
  factory.define("user")
    .attr("first_name", "First Name")
    .attr("last_name", "Last Name")
 
  factory.define("active_user").parent("user")
    .attr("active", true);
};
 
// test/bootstrap.js
before(function(done) {
  require("sails").lift({
    log: {
      level: "error"
    }
  }, function(err, sails) {
    if (sails) {
      // -- make factories global to your tests
      global.factory = require("sails-industrial-factory");
      //-- load factory definition files from test/factories
      factory.load();
    }
    done(err);
  });
});

To load factory files from different folder:

factory.load("/path/to/factories");
