* v3.20.2...v3.24.0 * Fix handle undefined outlet in route component * Don't use template helper for optional modal.open Using the optional-helper here will trigger a computation in the same runloop error. This is because we are setting the `modal`-property when the `<Ref>` component gets rendered which will update the `this.modal`-property which will then recompute the `optional`-helper leading to this error. Instead we will create an action that will call the `open`-method on the modal when it is defined. This gets rid of the double computation error as we will not access the modal property twice in the same runloop when `modal` is getting set. * Fix - fn needs to be passed function tab-nav We create functions in the component file instead so that fn-helper stops complaining about the need to pass a function. * Update ember-exam to 6.1 version "Makes it compatible" with ember-qunit v5 * scheduleOnce setMaxHeight paged-collection We need to schedule to get around double-computation error. * Fix - model.data is removed from ember-data This has been private API all along - we need to work around the removal. Reference: https://github.com/emberjs/data/pull/7338/files#diff-9a8746fc5c86fd57e6122f00fef3155f76f0f3003a24b53fb7c4621d95dcd9bfL1310 * Fix `propContains` instead of `deepEqual` policy Recent model.data works differently than iterating attributes. We use `propContains` instead of `deepEqual`. We are only interested in the properties we assert against and match the previous behavior with this change. * Fix `propContains` instead of `deepEqual` token * Better handling single-records repo test-helper `model.data` has been removed we need to handle proxies and model instances differently. * Fix remaining repository tests with propContains We don't want to match entire objects - we don't care about properties we haven't defined in the assertion. * Don't use template helper for optional modal.open Using a template helper will give us a recomputation error - we work around it by creating an explicit action on the component instead. * Await `I $verb the $pageObject object` step * Fix no more customization ember-can No need to customize, the helper handles destruction fine on its own. * Fix - don't pass `optional` functions to fn We will declare the functions on the component instead. This gives us the same behavior but no error from `fn`, which expects a function to be passed. * Fix - handle `undefined` state on validate modifier StateChart can yield out an undefined `state` we need to handle that in the validate modifier * Fix linting errors tests directory * Warn / turn off new ember linting issues We will tackle them one by one and don't want to autofix issues that could be dangerous to auto-fix. * Auto-fix linting issues * More linting configuration * Fix remaining linting issues * Fix linting issues new files after rebase * ui: Remove ember-cli-uglify config now we are using terser (#14574) Co-authored-by: John Cowen <johncowen@users.noreply.github.com> |

# DataLoader
`<DataLoader />` works similarly to, and uses, `<DataSource />` but additionally
exposes various common states based on the status of the loading of the data.
These states are exposed as slots to enable you to easily render different
elements based on the state of the data.
Use the `@dataSource` decorator in your repositories to define URI to async
method mapping.
```javascript
class SomethingRepository extends Service {
@dataSource('/:partition/:nspace/:dc/services')
async youCouldCallItAnythingTodoWithGettingServices(params) {
console.log(params);
// {partition: "partition", nspace: "nspace", dc: "dc"}
return getTheThing(params);
}
}
```
```hbs preview-template
<DataLoader
@src="/partition/nspace/dc/services"
as |loader|>
<BlockSlot @name="loading">
Loading...
</BlockSlot>
<BlockSlot @name="error">
Error {{loader.error.status}}
</BlockSlot>
<BlockSlot @name="disconnected">
Whilst we could load the initial data, something happened subsequently that
meant we could load longer load updates to the data.
</BlockSlot>
<BlockSlot @name="loaded">
{{#each loader.data as |service|}}
{{service.Name}}<br />
{{/each}}
</BlockSlot>
</DataLoader>
```
## Attributes
| Argument | Type | Default | Description |
| --- | --- | --- | --- |
| `src` | `String` | | The source to subscribe to updates to, this should map to a string based URI |
## Exported API
| Name | Type | Description |
| --- | --- | --- |
| `data` | `object` | The loaded dataset once any data has been loaded successfully |
| `error` | `Error` |The error thrown if an error is encountered whilst loading data |
| `invalidate` | `function` | Invalidate the data represented by the DataLoader, therefore forcing a re-request of data for the DataLoader |
## Slots
| Name | Description |
| --- | --- |
| `loading` | Rendered whilst waiting for the initial data to load. |
| `error` | If there is an error only whilst waiting for the initial data to load, this slot is rendered. |
| `disconnected` | Rendered when the initial data has already loaded, but a subsequent set of loaded data causes an error to be thrown.|
| `loaded` | Rendered once the initial data is loaded and on subsequent successful loads of data. |
