Operation

mod:Operation

Operation implementation

class DIRAC.RequestManagementSystem.Client.Operation.Operation(fromDict=None)

Bases: object

Parameters:

• OperationID (long) – OperationID as read from DB backend
• RequestID (long) – parent RequestID
• Status (str) – execution status
• Type (str) – operation to perform
• Arguments (str) – additional arguments
• SourceSE (str) – source SE name
• TargetSE (str) – target SE names as comma separated list
• Catalog (str) – catalog to use as comma separated list
• Error (str) – error string if any
• parent (Request.Request) – parent Request instance

It is managed by SQLAlchemy, so the RequestID, OperationID should never be set by hand (except when constructed from JSON of course…) In principle, the _parent attribute could be totally managed by SQLAlchemy. However, it is set only when inserted into the DB, this is why I manually set it in the Request _notify
