Content items Moderation

[justscribe]

I have a requirement to implement a moderation for the content items.
It is not for particular content type, but for any type, that have a ModerationPart in it.
Moderation part have some Status and Comments fields.
I've implemented such a module, and figured out how to show it only for Moderator role (with ContentPartDisplayDriver), that can later edit it.
But the problem is in filtering out content items, that were not moderated or moderation is not passed.
I'm talking about GraphQL and RestAPI, how to not show items in the results via these API's, that has a ModerationPart and not allowed by it?
Already tried "AuthorizationHandler" without a luck,
Thank you for any help.

Maybe the "IContentHandler" is the answer, I'll check.

ContentHandler for Loading/Loaded just happens, I can't manipulate the context.
Seems there is no way to filter them on the backend for sure.

Do you have a minimal repo? I think you could filter the items based on the moderation status, this could be done easily if you have an index

@hishamco The index is present, but without the purpose=)

I mean to filter them for any kind of retrieving.
For example, via this GraphQL query - "query{ myType { displayText } }".
It will show the list of all items with "myType" type, but I don't want to show items that were not moderated.
As I see from the GraphQL sources, this is kind of Dynamic query, and it retrieves items directly, without using any filters (except for item status, published, draft etc.) or handlers.
I see only 2 options:

1. Add changes to OrchardCore itself and build own version.
2. Implement own controller/s, restrict from using GraphQL/built in REST API.
   Both options like meh...

TBH, I didn't work much with GraphQL, but if you have a content APIs, I could check what the issue is
