If we see adapter: RestAdapter.create() without any extensions in a model's configuration we should remove it altogether as the default behaviour of Ember Data's adapter would be enough.

Before

export default IntercomModel.extend({}).reopenClass({
  adapter: RestAdapter.create(),
  url: '/some/url'
});

After

export default IntercomModel.extend({}).reopenClass({
  url: '/some/url'
});

Thanks for this codemod! I am currently using it in an EmberModel -> Data migration I am performing. I noticed a reference to the below doc in the generated code. Any chance this doc could be shared in this project?

If we see camelizeKeys: true (there are no instances of false) in a model's configuration we should remove it altogether as this is default behaviour in Ember Data.

Before

export default IntercomModel.extend({}).reopenClass({
  camelizeKeys: true,
  url: '/some/url'
});

After

export default IntercomModel.extend({}).reopenClass({
  url: '/some/url'
});

We currently migrate IntercomModel.extend to DS.Model, but there are a few instances of using Ember Model's Model directly.

Before

export default Model.extend(UserAvatarData, {

After

export default DS.Model.extend(UserAvatarData, {

We should remove this rule when converting from IntercomModel to DS.Model

//eslint-disable-next-line intercom/no-ember-model

There are two forms we'll need to accommodate

//eslint-disable-next-line intercom/no-ember-model
let SomeModelVar = IntercomModel.extend({
});

//eslint-disable-next-line intercom/no-ember-model
export default IntercomModel.extend({
});
