look at containerService

[wmoore]

Investigate the possibility of using the container service for various 'container' methods.

• Review, organise & group current 'container' methods together in webclient_gateway
• Try using container service for one or more methods:
  • Does container service provide filter by user etc
  • Are the details, owner etc loaded?
• NB: Given the current 'lazy loading' strategy in Blitz Gateway, it never makes sense to load children of any object?

For example: listProjects can be implemented with code like this:

def listProjects(self, eid=None):
    params = omero.sys.Parameters()
    params.map = {}
    f = omero.sys.Filter()
    f.ownerId = rlong(long(eid))
    params.theFilter = f
    cs = self.getContainerService()
    ps = cs.loadContainerHierarchy("Project", None, params)
    projs = [ProjectWrapper(conn, p) for p in ps]
    projs.sort(key=lambda x: x.name)
    return projs

Points to note:

• sorting by name is client-side (maybe don't bother)?
• Project.details.owner and Project.details.creationEvent are not loaded (need to be loaded by subsequent calls if needed.
• Should they be loaded by the Container Service?

[wmoore]

If we move to using Container Service for the various loading methods in gateway, then we need to load details in subsequent calls OR change Container Service.

NB: up till now, all calls to creationEventDate() have been using iQuery, since the method was broken for returning the already-loaded details.
