Hey @ryelle - thanks for your work here 👍 .
I tested it and seems to be working well! I've left a couple of comments but nothing major.

@ryelle Is there anything specific left for this PR before it can be merged? |
@StevenDufresne It's been awhile since the original PR, if you could just check it over to make sure nothing slipped by in the rebase I'd appreciate it. |

Description
Some blocks (or post types) have a restricted list of what can be added (
allowedBlocks, aka child blocks), and we might not be able to add a new block to those containers. Currently, we list all found blocks regardless of this issue, which causes unexpected results when the user tries to add them.This PR follows from #22240 & #24148, but should fix the root issue at both.
I've updated the
canInsertBlockTypeselector to accept an object for the blockType. If an object is passed in, it will not usegetBlockType, which would only work for an already-installed block type. This should be fine for existing uses of the selector, since they'll pass in a string & behavior will stay the same. For the block directory, we can pass in our block object, so that potential downloadable blocks can be checked against the current container.How has this been tested?
You can download & install this example container block that only allows
"core/image", "core/heading", "core/paragraph", "book-review-block/book-review"in the container, and has a filter in the PHP file to restrict blocks in all post types to justNow search for "Stars", and you'll see two results in the main editor content, and 1 available result in the demo block. Search for something totally different (ex, recipe), and you'll get the "No blocks found in your library." result.
Screenshots
In the post, I've set allowedBlocks to allow these 2 blocks that return for the query
stars(in reality, 4 blocks are returned)In this container block, only one block matches allowedBlocks, so only one is shown:
