- In Ghost, 'context' means the page or section of a blog we're currently within
when rendering a theme, e.g. 'post' or 'tag' or 'home'.
- In handlebars 'context' refers to the blob of JSON that is tied to a template.
- These two uses of the word 'context' have gotten very confusing, so I've removed all usage of 'context' within the Ghost handlebars helpers, EXCEPT where they actually refer to the current context (e.g. the is helper)
issue #5976
- break out the labs check into a utility
- wrap the get helper in a labs check, so it only works if the checkbox is checked
- make the get helper output an error to both the server and browser console if used when not enabled
refs #5943
- removed featured, tag and author parameters from posts API
- featured was only used in tests
- removed role filter from users API
- role was only used in tests
- fixed up the tests, skipping those that don't quite work yet
closes#4439
- adds basic get helper which works with the current API
- allows theme developers to make requests against the API
- supports block params and @error message
- includes 100% test coverage using posts
----
The `{{#get}}` helper is an asynchronous block helper which allows for making
requests for data from the API. This allows theme developers to customise the
data which can be shown on a particular page of a blog.
Requests can be made to the posts, tags or users API endpoints:
```
{{#get "posts" limit="3"}}
{{#foreach posts}}
<a href="{{url}}">{{title}}</a>
{{/foreach}}
{{/get}}
```
The `{{#get}}` helper must be used as a block helper, it supports `{{else}}`
logic, for when no data matching the request is available or if an error has
occurred:
```
{{#get "posts" tag="photo"}}
...
{{else}}
{{#if @error}}
<p>Something went wrong: {{@error}}</p>
{{else}}
<p>No posts found</p>
{{/if}}
{{/get}}
```
The helper also supports block params, meaning the data it outputs can be
given a different name:
```
{{#get "posts" featured="true" as |featured|}}
{{#foreach featured}}
...
{{/foreach}}
{{/get}}
```
Please Note: At present asynchronous helpers cannot be nested.
