Instance Method Details

#available_child_collections ⇒ Object

Deprecated.

this method is unused by hyrax, and is effectively a delegation to ‘Hyrax::Collections::NestedCollectionQueryService`. if you want to be sure to use nested indexing to generate this list, use the query service directly.

For the given parent, what are all of the available collections that can be added as sub-collection of the parent.

this method is unused by hyrax, and is effectively a delegation to ‘Hyrax::Collections::NestedCollectionQueryService`. if you want to be sure to use nested indexing to generate this list, use the query service directly.

For the given child, what are all of the available collections to which the child can be added as a sub-collection.

end

#validate_add ⇒ Object

when creating a NEW collection, we need to do some basic validation before rerouting to new_dashboard_collection_path to add the new collection as a child. Since we don’t yet have a child collection, the valid? option can’t be used here.
