NextJS ISR Page Revalidation

[zarif-lh]

I will get straight to the point.

• I have a blogs collection which contains blog documents.
• I have a pages collection that has tabbed fields. One of the tabs is called content (it's a named tab).
• The content tab has a blocks type field called pageSections.
• pageSectons can contain a carousel block that can reference blogs collection items. It also contains other blocks i.e hero, form block etc.

I have a simple revalidate hook that runs whenever the blogs or pages collection is updated. It calls revalidatePath with the slug of the collection that is being updated.

The issue is with updating related pages that uses content from the collection being updated.

For example:

The blogs collection documents contains a cardImage that is rendered in the carousel block in pages collection documents.

When the editor updates the cardImage in blogs I want to be able to find which collections reference the blogs collection document being updated and call revalidate path in those documents.

I have tried to use join field to get relationships, but I failed to get it work with blocks field.
