Hey All,

 

I am wondering why the getdataattime endpoint doesn’t seem to return some of the meta data type fields like DESC or EGU?  I tried to go into the policies.py file and add in some more fields to export but not sure I am doing it in the right spots.  These are the two parts in policies.py that I thought would need to be changed to handle the other fields.  Although I am still not sure why the getdataforpvs is able to export the meta data fields.

 

 

 

# Define a list of fields that will be archived as part of every PV.

# The data for these fields will included in the stream for the PV.

# We also make an assumption that the data type for these fields is the same as that of the .VAL field

def getFieldsArchivedAsPartOfStream():

                return ['HIHI','HIGH','LOW','LOLO','LOPR','HOPR','DRVH','DRVL'];

 

 

if "RTYP" not in pvInfoDict:

                                pvPolicyDict["archiveFields"]=archiveFields

                else:

                                pvRTYP=pvInfoDict["RTYP"]

                                if pvRTYP=="ai":

                                                archiveFields=['HIHI','HIGH','LOW','LOLO','LOPR','HOPR']

                                elif pvRTYP=="ao":

                                                archiveFields=['HIHI','HIGH','LOW','LOLO','LOPR','HOPR','DRVH','DRVL']

                                elif pvRTYP=="calc":

                                                archiveFields=['HIHI','HIGH','LOW','LOLO','LOPR','HOPR']

                                elif pvRTYP=="calcout":

                                                archiveFields=['HIHI','HIGH','LOW','LOLO','LOPR','HOPR']

                                elif pvRTYP=="longin":

                                                archiveFields=['HIHI','HIGH','LOW','LOLO','LOPR','HOPR']

                                elif pvRTYP=="longout":

                                                archiveFields=['HIHI','HIGH','LOW','LOLO','LOPR','HOPR','DRVH','DRVL']

                                elif pvRTYP=="dfanout":

                                                archiveFields=['HIHI','HIGH','LOW','LOLO','LOPR','HOPR']

                                elif pvRTYP=="sub":

                                                archiveFields=['HIHI','HIGH','LOW','LOLO','LOPR','HOPR']

                                pvPolicyDict["archiveFields"]=archiveFields

 

                return pvPolicyDict
