Irregular rule for unitOfMeasure to unitsOfMeasure does not work

[adam-knights]

I tried adding

inflector.irregular('unitOfMeasure', 'unitsOfMeasure');

To my app and it doesn't work, it hits /api/unitOfMeasure, it should now be hitting /api/unitsOfMeasure

I created a unit test in /tests/unit/inflector-test.js that fails on both asserts in latest master:

test('unit of measure', function(assert) {
  inflector.irregular('unitOfMeasure', 'unitsOfMeasure');

  assert.equal(inflector.singularize('unitsOfMeasure'), 'unitOfMeasure', 'irregular singularization rule was applied');
  assert.equal(inflector.pluralize('unitOfMeasure'), 'unitsOfMeasure', 'irregular pluralization rule was applied');
});

---

I had a quick debug, it seems to find the irregular rule ok and populate substitution in the for loop, but then I think the return in that loop of return word.replace(rule, substitution); doesn't do the job as word is unitOfMeasure and rule is unitofmeasure, so there is no match due to the casing?

The above research stemmed from me trying to define plurals in DS.RESTAdapter.extend, and this working for all but unitOfMeasure: unitsOfMeasure. I'm guessing this feeds into ember inflector?

[adam-knights]

@fivetanley Any thoughts on whether this is a bug that would be affecting me defining this in Ember Data, or should I go back to Ember data and post this there?

We aim todo whatever the rails inflector does, if someone wants to check we can decide if this is a bug or not.

'unitOfMeasure'.pluralize # => "unitOfMeasures"
'unitsOfMeasure'.singularize # => "unitsOfMeasure"

@fsmanuel thats with an irregular rule defined?

[fsmanuel]

@adam-knights rails c i have nothing defined. It's just what the rails inflector does.

have you seen warp-drive-data/warp-drive#3802 and here warp-drive-data/warp-drive#3888 (comment)

[fsmanuel]

@adam-knights what version of ember-data are you using. still seems to be a problem...

[adam-knights]

I'm stuck on 1.13.15 currently, happy to revisit/test this when we are able to move upto a newer release

[fsmanuel]

which adapter?

[adam-knights]

RESTAdapter, so for plural of this example I would do:

export default DS.RESTAdapter.extend(DataAdapterMixin, {
  plurals: {
    unitOfMeasure: 'unitsOfMeasure'
  }
});

[fsmanuel]

@adam-knights if the problem only occurs with the path you can patch pathForType
https://github.com/emberjs/data/blob/v1.13.15/packages/ember-data/lib/adapters/build-url-mixin.js#L319

But i guess the next will be the payload...

I'm also being affected by this bug:

//rule
inflector.irregular('tipoDocumento', 'tiposDocumento');

//test
Ember.Inflector.inflector.pluralize('tipoDocumento');
=> "tipoDocumento"
Ember.Inflector.inflector.singularize('tiposDocumento');
=> "tiposDocumento"

And to improve this scenario I tested on ActiveSupport

Definition

ActiveSupport::Inflector.inflections do |inflect|
  inflect.irregular 'tipoDocumento', 'tiposDocumento'
end

Test

$ rails c
Loading development environment (Rails 3.2.22)
2.2.4 :001 > "tipoDocumento".pluralize
 => "tiposDocumento" 
2.2.4 :002 > "tiposDocumento".singularize
 => "tipoDocumento" 
2.2.4 :003 > 

As you can see the behaviour is different.

@stefanpenner any new on this one?
I'm still affected by this.
If confirmed as a bug I can help come up with the solution, seems pretty straightforward.

[fsmanuel]

@escobera which version of ember, ember-data and ember-inflector are you using?
