@psihius can you please share a screenshot of how i looks like when we embed a data table in a form? |

| $embedContext = $context->getRequest()->query->all('embedContext'); | ||
| if (\array_key_exists('mappedBy', $embedContext)) { | ||

| $filterValue = $embedContext['embeddedIn'] ?? null; | ||
| if (null !== $filterValue) { | ||
| // Use the parameter conversion capabilities of Doctrine | ||

| $relatedEntityMetadata = $queryBuilder->getEntityManager()->getClassMetadata($relatedEntityFqcn); | ||

| $doctrineType = Type::getType($type); | ||
| $platform = $queryBuilder->getEntityManager()->getConnection()->getDatabasePlatform(); | ||

| } | ||

| $associationMapping = $metadata->getAssociationMapping($filterProperty); | ||

| $queryBuilder->andWhere(sprintf('%s.%s', $rootAlias, $filterProperty) . ' = :filterValue') | ||

| } | ||
| } | ||

There was a problem hiding this comment.
Can you move this into a separate method to keep the index action method simple to understand?
Not sur of what's the best between creating a new createEmbededIndexQueryBuilder() or something like filterEmbededQueryBuilder()

Moving it is no problem, as I said - this is a rough draft that needs lots of work :)
As for the second point - maybe creating dedicated embedded(index|detail|edit|new|delete) actions or even rolling a EmbeddedAbstractController might be a better way of doing it, but then you have to maintain similar code. So the question is - what would be a better approach to refactor here so it is better long term? Those action methods already are pretty sizeable and adding to them might be a bit overkill :)
Unset all query parameters on the initial embedded crud URL

@psihius anything new here? Wondering if you are still working on this feature... |
Note: this is a WIP and a Request For Comments aka feedback. This needs a lot more development, especially on making things work via AJAX and having a dedicated "embedded" layout, because right now it does not have as smooth functionality as it needs to. Also, a bunch of JS is commented out because I did not get to it yet. Filters are gonna be a major headache and probably would need improvements overall. This might turn into an epic of its own.
This is the ability to embed a whole data grid "index" page into a form via the
EmbedField::new('relation')This was based on #3543 PR, but a lot has changed since 3.x days and that PR needed a full re-work and bigger changes to the EA.
Lots to work on:
All feedback, patches and discussion are welcome. There's a wide field of discussion on how to approach this and implement it - I am thinking that we probably should have a dedicated
embedded_layoutform and have a dedicated template for the embedded grid rather than doing a single block render like it's doing now.
