Required for REST URLs which require data to be populated on call.
For example, PUT admin/campaigns/set/:id/publish to publish a campaign.
At the time when createEndpointFetcher() is called, the ":id" parameter can not be resolved,
since the "data" argument is passed in once the returned function is evaluated (since the component using it).
Since the whole idea of createEndpointFetcher() is that components shouldn't know about the backend internals,
its not the right place to interpolate urls.
I'm sending through any payload data in addition to replacing URLs, to keep the API simple for the component.
Again, it shouldn't worry about the presence URL interpolation. The trade off here is that data will be submitted
both in the payload (in case of a POST, PUT or DELETE request), as well as (optionally) in the URL.
Tests were previously excluded from eslint calls. This leads to messier
code inside tests, and potentially errors.
Now they all meet the listing rules, and so we don’t need to ignore
tests in .eslintignore.
FIX: Ensure post has correct content-type header.
Exporting silverstripe-backend lets other modules (such as asset-admin)
use it.
In addition, the Content-type header of a post request of URL-encoded
data was being set to text/plain by default, which isn’t correct and
stopped PHP from interpreting it.
Renaming state operations from 'campaign' to 'record'.
Implemented API endpoint retrieval of GridField data.
Added more mock data into CampaignAdmin (rather than hardcoding in client),
to be replaced by CampaignAdmin API endpoint querying the real datamodel.
Using more native isomorphic-fetch instead of jQuery.ajax
to minimise dependencies and get into a more forward-thinking API.
Also catching errors in ReactJS API backend:
Emulate jQuery.ajax() behaviour. Might change at a later point
if we have a general purpose backend with a promise-based catch()
implementation.
