Sequences

[mgraham]

It would be nice to have FactoryGirl-style sequences.

In the meantime, I'm doing something like this:

FactoryGuy.define('user', {
  default: {
    name: 'Person 1',
    email: 'person_1@example.com'
  },
  sequence: {
    name: function(n)  { return 'Person ' + n },
    email: function(n) { return 'person_' + n + '@example.com' }
  },
});


// makeFixtureList
//
// - assumes a factory set up like this:
//         FactoryGuy.define('user', {
//           default: {
//             name: 'Person',
//             email: 'person@example.com'
//           },
//           sequence: {
//             name: function(n)  { return 'Person ' + n },
//             email: function(n) { return 'person_' + n + '@example.com' }
//           },
//         });
//     
//
//
// makeFixtureList(count, model, sequence_fixture_name = 'sequence')
// e.g.
//      makeFixtureList(10, 'user')   
//      - makes 10 users, using 'sequence' as the name generators, and 'default' to actually create the users
//      - the equvalent of calling:
//            store.makeFixture('user', { name: 'Person 1', email: 'person_1@example.com' })
//            store.makeFixture('user', { name: 'Person 2', email: 'person_2@example.com' })
//            ...
//            store.makeFixture('user', { name: 'Person 10', email: 'person_10@example.com' })
//
var makeFixtureList = function(count, model, sequence_fixture_name) {
  var store = App.__container__.lookup('store:main'));

  if (!sequence_fixture_name) sequence_fixture_name = 'sequence';

  var attributes_generators = FactoryGuy.getModelInfo(model)[sequence_fixture_name];

  for (var i = 1; i <= count; i++) {
    var attributes = {}; 
    for (var key in attributes_generators) {
      var func = attributes_generators[key];
        var text = func(i);
        attributes[key] = text;
    }

    store.makeFixture(model, attributes);
  }

}

@mgraham, yes, we can do this!
Thanks!

@mgraham, can you fork the repo, add this feature with tests .. make pull request and I can add it?

[mgraham]

Sure - I will try to do this! It may not be for a week or two, though.

[danielspaniel]

I beat you to it .. since I had to refactor the heck out of code to make the sequences easy to use, I just did this on a binge yesterday.
The sequences and makeList feature are now in version 0.1.2 or in master

Fantastic! Thank you!
