arcpy.AssignDefaultToField_management not assiging a default to a field

danieloccasionally

When originally setting this up I solved this problem ... somehow, now I can't recall how for the life of me.

After adding some fields to a file geodatabase feature class (TWP+"_RIGHTS"), I create and apply domains to three of the fields. The default is supposed to be "Choose", yet it just shows "<Null>". Any ideas how the problem can be corrected?

 # create and set domains to fields

arcpy.env.workspace = projectfilepath + county+"_"+TWPfileGDB 
RIGHTS = TWP + "_RIGHTS"
# Set local parameters
gdb = projectfilepath + county+"_"+TWPfileGDB
inFeatures = RIGHTS
default_value = 0

domName = "OpCo_Domain"
domain_description = "OpCo Choices"
inField = "OpCo"
# Process: Create the coded value domain

existingDomains = arcpy.da.ListDomains(gdb)
domain_names = [i.name for i in existingDomains]

if domName in domain_names:
    print(domName + " already exists")
    arcpy.management.AssignDomainToField(inFeatures, inField, domName)
    arcpy.AssignDefaultToField_management(inFeatures, inField, default_value)
    
else:
    print("creating domain " + domName)
    arcpy.management.CreateDomain(gdb, domName, domain_description, "TEXT", "CODED")
    domDict = {"0": "Choose", "1": "METC", "2": "ITCT"}
    for code in domDict:        
        arcpy.management.AddCodedValueToDomain(gdb, domName, code, domDict[code])
    # Process: Constrain the material value of distribution mains
    arcpy.management.AssignDomainToField(inFeatures, inField, domName)
    arcpy.AssignDefaultToField_management(inFeatures, inField, default_value)
    


domName_2 = "RightsType_Domain"
domain_description_2 = "RightsType Choices"
inField_2 = "RightsType"

existingDomains = arcpy.da.ListDomains(gdb)
domain_names = [i.name for i in existingDomains]

if domName_2 in domain_names:
    print(domName_2 + " already exists")
    arcpy.management.AssignDomainToField(inFeatures, inField_2, domName_2)
    arcpy.AssignDefaultToField_management(inFeatures, inField_2, default_value)
    
else:
    print("creating domain " + domName_2)
    arcpy.management.CreateDomain(gdb, domName_2, domain_description_2, "TEXT", "CODED")
    domDic_2 = {"0": "Choose", "1": "Easement", "2": "Fee", "3": "License"}
    for code in domDic_2:        
        arcpy.management.AddCodedValueToDomain(gdb, domName_2, code, domDic_2[code])
    # Process: Constrain the material value of distribution mains
    arcpy.management.AssignDomainToField(inFeatures, inField_2, domName_2)
    arcpy.AssignDefaultToField_management(inFeatures, inField_2, default_value)
        
        
        
domName_3 = "Type_of_Use_Domain"
domain_description_3 = "Type_of_Use Choices"
inField_3 = "Type_of_Use"

existingDomains = arcpy.da.ListDomains(gdb)
domain_names = [i.name for i in existingDomains]

if domName_3 in domain_names:
    print(domName_3 + " already exists")
    arcpy.management.AssignDomainToField(inFeatures, inField_3, domName_3)
    arcpy.AssignDefaultToField_management(inFeatures, inField_3, default_value)

else:
    print("creating domain " + domName_3)
    arcpy.management.CreateDomain(gdb, domName_3, domain_description_3, "TEXT", "CODED")
    domDict_3 = {"0": "Choose", "1": "Full T-Line", "2": "Substation", "3": "Railroad", "4": "Overhang Only", 
                "5": "Veg Management Only", "6": "Access", "7": "Other"}
    for code in domDict_3:        
        arcpy.management.AddCodedValueToDomain(gdb, domName_3, code, domDict_3[code])
    # Process: Constrain the material value of distribution mains
    arcpy.management.AssignDomainToField(inFeatures, inField_3, domName_3)
    arcpy.AssignDefaultToField_management(inFeatures, inField_3, default_value)


print("Completed"+" "+time.strftime("%x" +" "+ "(%a)" +" "+ "at"+" "+"%I:%M"))

Ah, I corrected my code to reference each domains' dictionary ! Thank you @DonMorrison1 

 

 

field = "OpCo"
expression = 0
arcpy.management.CalculateField(RIGHTS, field, expression, "", "", "", "ENFORCE_DOMAINS")

field = "RightsType"
expression = 0
arcpy.management.CalculateField(RIGHTS, field, expression, "", "", "", "ENFORCE_DOMAINS")

field = "Type_of_Use"
expression = 0
arcpy.management.CalculateField(RIGHTS, field, expression, "", "", "", "ENFORCE_DOMAINS")
