Better way to do chgrp

[Manz]

Hey Guys

We've hacked a way to move datasets between groups using the command line, but Jason Swedlow mentioned it would be worth asking if there was a better way to do this. Currently I've done it via command line as below. The grand idea behind this is moving a dataset from a private group to a public one so that we can display it to the public re the public user.

Code: Select all


def chgrpCol(dsId,publicGroup,session):
        theAdminofGroup=cleanQuery(session)
        publicGroup=cleanQuery(publicGroup)
        dsId=cleanQuery(dsId)
        chgrpline=string.join([omerohomedir,"/bin/omero -s localhost -k ",session," chgrp '",publicGroup,"' /Dataset:",dsId ],"")
        a=subprocess.call([chgrpline],shell=True)
        logger.info(string.join(["CHGRPCOL - The collection ",str(dsId)," has been moved to the group ",str( publicGroup) , " using the line -",str(chgrpline),"- with results",str(a)],""))
        return string.join(["CHGRPCOL - The collection ",str(dsId)," has been moved to the group ", str(publicGroup)],"")

Hi Manda,

other than not knowing what you are doing with "theAdminofGroup" the way you are doing this is certainly fine, functionally. If you are using Python as a scripting language, though, there are two further options. 1) you could use the CLI object directly and not need to use subprocess. Something like "import omero.cli" and then use "omero.cli.CLI" directly. Or perhaps 2) use the API and just invoke "omero.cmd.Chgrp". Nevertheless, all 3 are valid, and you can pick based on your particular needs.

Cheers,
