[workflow] creating a node without an video upload

[peter]

Current situation: A node that has a cck video field is optional. So you can create a node without an upload. After saving no asset will be created in MediaMosa.

Problem: It is possible to add metadata (#417, #418) to that node without a video. So no asset has been created, so DB & QDC metadata can not be saved to MediaMosa.

Desired situation: Create a asset even when no mediafile has been uploaded.

My notes on implementation of this ticket;

• Use /asset/create to create the asset.
• Remember that assets can be deleted by other means than this module.
• Build a function that retrieves the asset for the node and create the asset if the asset is no longer in MediaMosa. Then at any point in the code where you need or create the asset, call that function.
• Do not store the asset_id in the node, use reference_id in the asset to reference back to the node.
• You can only be sure that the node exists, but never that the asset exists.

@Robert:

Ready for review.

Situation after development: Asset is always created for node. If there is a node without asset, then the application create one for it.

PS. "Do not store the asset_id in the node, use reference_id in the asset to reference back to the node."
The embedded field stores the asset_id now (not the mediafile_id).
