Let's leave the unit tests and not delete them.

One issue here is the revisions controller currently guesses that the parent controller is a instance or sub class of post controller. Means means it expects some classes and properties that might not exist in WP_REST_Global_Styles_Controller.

My biggest worry about this WP_REST_Global_Styles_Controller does not extend the WP_REST_Posts_Controller. Future refactors would might meaning breaks here, as class methods / properties do not match. I feel like if we are going to make this change, we go the whole way and convert WP_REST_Global_Styles_Controller to extend WP_REST_Posts_Controller. Then we can use the work done in 1f51e1f, to regsiter custom post / revision controllers when registering the global post type. Then this manaul regsiteration can be removed here.

// Global Styles revisions.
$controller = new WP_REST_Global_Styles_Revisions_Controller();
$controller->register_routes();
// Global Styles.
$controller = new WP_REST_Global_Styles_Controller();
$controller->register_routes();

Thanks for the feedback.

Looks like this point was raised by @TimothyBJacobs back when the endpoint was introduced: WordPress/gutenberg#35801 (review)

I think in this case, considering how custom the global styles API is, I think it is fine to extend the base controller instead of using WP_REST_Posts_Controller.

@TimothyBJacobs do you think this is still the case? The "custom" nature of global styles, I think, still stands.

I'm happy to take a stab at it if we think inheriting WP_REST_Posts_Controller will bring more benefits as described above.

The big difference is now 1f51e1f is committed, we can make custom revisions endpoints. I think now we can have custom revisions, it register this as a post endpoint and revisions endpoint.

Let's try this change in another PR, see if it makes sense.

Works pretty well over at #6008, but I'm wondering if registering endpoints should also be optional - e.g., Global styles should be able to opt out of autosaves routes

Perhaps explicitly setting '${ autosave | revision }_rest_controller_class' to false when registering the post?

Ora a supports_autosaves, similar to supports_revisions? 🤷🏻

I'm happy to get a PR up to test this out.

Closing in favour of #6022

@spacedmonkey Just checking, this PR was working as a stand alone patch.

Did you close with the intention to port these changes over to #6022? Otherwise I think we should reopen.

@ramonjd I thought we were aligned on #6022? I feel like #6022 is good to commit.

Definitely, but just not sure why this PR needed to be closed?

I think maybe our wires just got crossed 😅

This PR affects WP_REST_Global_Styles_Revisions_Controller (Revisions) not WP_REST_Global_Styles_Controller. I just assumed you were going to bundle them into #6022.

Happy to reapprove #6022 - it's good to go, but we still need this PR I think.

To be clear, #6022 needs to be part of this PR. Let's do this change in one commit.

Ah, got it. Thanks, for clearing that up.

#6022 seemed to work well on its own, but I can pull over the changes into this PR if that's your advice.

Thanks again.

I believe the contractor, get_item and update_item methods no longer need to be overridden in the global style controller.

I also had a note about marking this endpoint as not support batching.

I love this change, as it allows the gutenberg plugin to override these classes easier.

removing __construct, get_item and update_item in favour of the parent class methods

Add $allow_batch property, setting it to false

👍🏻 Done

What do you think about get_post() as well?

The functions are the identical, the only difference being the error message, which seems fairly samey.

In global styles controller:

		$error = new WP_Error(
			'rest_global_styles_not_found',
			__( 'No global styles config exist with that id.' ),
			array( 'status' => 404 )
		);

In post controller:

		$error = new WP_Error(
			'rest_post_invalid_id',
			__( 'Invalid post ID.' ),
			array( 'status' => 404 )
		);
