Introduction /collection/{id}/count call

[Michiel.Schok]

Which returns the number of assets in the collection, without asset details.

Parameters supported:
hide_empty_assets, default false. When hide_empty_assets is true, only the non-empty assets are counted.

Background:
At the moment, the only way to gather information about the total number of assets in a collection is an
/collection/{id}/asset?limit=10 query, where the asset-detail results are ignored, and only the total count in the header is used. That query operation is resource intensive, while assets must be sorted, and the <granted> field must be calculated.
The /count call would be a very cheap alternative.

[Michiel.Schok]

An alternative approach is the extension of the current
/collection/{id} call, which has to provide the

<numofvideos>xyz</numofvideos> as part of the regular xml-response.

We observe that that number of assets is already part of the
/collection search query, so the number is known to the system and does not have to be calculated at runtime.

Ready. It is in my repository.

It seems it's not implemented? Strange...

We decided not to use

/collection/$coll_id/count,

be instead we made

/collection/$coll_id/asset/count.

However, 2.2.1 version will only give back the number of videos inside the collection, not matter the is_empty_asset value. The 2.2.2 version has the is_empty_asset parameter, put that on TRUE and it will return the asset count that are not empty.

Also the call /collection/$coll_id has been extended with the is_empty_asset parameter.

Fixed -> 2.2.2 Build 919.

[Michiel.Schok]

Hopefully the parameter is called 'hide_empty_assets'...

[robert]

Parameter is called 'hide_empty_assets', was my typo in the text.

(The name 'is_empty_asset' is used in database as field name).

[Michiel.Schok]

It is implemented as requested.

Documentation on  http://beheer.vpcore.snkn.nl/admin/mediamosa/browse/restcall/collection-%24coll_id-asset-count/GET is allright, but the documentation at http://mediamosa.org/api is missing.

I won't accept the issue, but someone else may do this if missing documentation is not an issue for them.

API documentation is not missing anymore:
