How to select/populate custom attributes

[Tilt 15]

Hi,

is there a way to get all the custom_attributes in a query or a session.populate() call? I can do

  session.query("select custom_attributes from Shot where ....")

but when I check the values with "auto_populating False", they are mostly Symbol(NOT_SET), except for default values.

I can't do "select custom_attributes.fstart from Shot where ..." because that throws 

  ftrack_api.exception.ServerError: Server reported error: KeyError(u'fstart')

as does session.populate(shot, "custom_attributes.fstart")

The reason I'm asking is that I usually need a bunch of custom attributes so I want to speed things up and reduce queries.

I think you can get rid of some extra queries by selecting value:

  session.query("select custom_attributes.value from Shot where ....")

I'm working on a fix for this right now that will speedup custom attributes so that your query above will fetch all necessary data in one go. This is a larger change in our backend and api so there will be some time before it is properly tested and released. But just so you know; we are aware of this and working on it.

Hi Mattias!

Are there any updates regarding this feature?

What I want is to get only the custom attributes value of a ftrack entity.

shot_custom_attributes = session.query("select custom_attributes from Shot where ....")

Hi Remus,

Just so that I understand - is this about fetching just a single custom attribute (for performance reasons) rather than all?

[Remus Avram 54]

Not really. It would be cool if we could fetching only the custom attributes of an ftrack entity instead of all the data (children, parent, etc)

I see, there are some substantial changes in 3.5.0 to custom attributes - hopefully the issue will be resolved then. I've contacted you in support-case #30782 about this.
