Use F5 REST API Python SDK to update an external datagroup
I have working code using the F5 Python REST SDK that can upload a txt file and createan external datagroup from it. But I cannot figure out how to use the API to update that datagroup file without deleting the datagroup and recreating it. All of the examples I can find (e.g.https://devcentral.f5.com/s/question/0D51T00006i7j1ySAA/upload-programatically-external-data-group-file) do the following: create a datagroup file object from a sourcepath create a datagroup object from the datagroup file object display the created object's attributes Then they delete the datagroupobject and datagroup file object so that they can run again. I cannot find a way to reloadthe data from an updated data file into an existingdatagroupobject. I havealso seen code that can walk adatagroup and update items in it one by one, but I'd really like touse a file updatemodel. Any ideas? Code sample follows: from f5.bigip import ManagementRoot # Connect to the BigIP mgmt = ManagementRoot("IP-FIXME", "USER-FIXME", "PASSWD-FIXME") def showDatagroups() : print("\n\n**** Showing Datagroups") dgs = mgmt.tm.ltm.data_group.externals.get_collection() for idx, dg in enumerate(dgs): print("\n{}: {}".format(idx, dg.raw)) print("\n{}: {}".format(idx, dg.name)) if hasattr(dg, 'records'): print("\n{}: {}".format(idx, dg.records)) for record in dg.records: print("\nrec: {}".format(record)) else: print("\nObject {} has no records".format(dg.name)) def showDatagroupFiles(): print("\n\n**** Showing DatagroupFiles") dgFiles = mgmt.tm.sys.file.data_groups.get_collection() for idx, f in enumerate(dgFiles): print('\n{}: {}'.format(idx, f.raw)) def uploadFile(f): # This upload works - it places the file in the uploads folder. # But I cannot seem to access the file uploaded file with the datagroup create method print("\n\n**** Uploading datagroup file {}".format(f)) mgmt.shared.file_transfer.uploads.upload_file(f) def createDatagroupFile(source_path, dgname, dataType): print("\n\n**** Creating datagroup file {}, name {}, type {}".format(fname, dgname, dataType)) # check first if its there dgFiles = mgmt.tm.sys.file.data_groups.get_collection() found = 0 for idx, f in enumerate(dgFiles): if f.name == dgname: found = 1 break if found: print("File {} already exists".format(dgname)) # Here's where I would just update the file if I could else: print("Creating DG File {} from fname {}".format(dgname, sourcePath)) dgFile = mgmt.tm.sys.file.data_groups.data_group.create(sourcePath=source_path, name=dgname, type=dataType) def createDatagroupFromFile(name, file): print("\n\n**** Creating datagroup {} from file {}".format(name, file)) # check first if its there dgs = mgmt.tm.sys.file.data_groups.get_collection() found = 0 for idx, dg in enumerate(dgs): if dg.name == name: found = 1 break if found: print("Datagroup {} already exists".format(name)) # Here's where I would just update the datagroup if I could else: dgObject = mgmt.tm.ltm.data_group.externals.external.create(name=name, externalFileName=file) if __name__ == "__main__": fname = './dg_test5.txt' # using HTTP server for raw file - this is the only way I could get the upload to work sourcePath = 'http://127.0.0.1:8000/dg_test5.txt' dgfilename = 'dg_test5.txt' dgname = 'dg_test5' uploadFile(fname) createDatagroupFile(sourcePath, dgfilename, 'string') createDatagroupFromFile(dgname, dgfilename) showDatagroups() showDatagroupFiles()
