Having a Workspace like this

 

imageand the AttributeCreator like

 

 

imageCan you please let me know how I can pass the AttributeCreator Values into the PythonCaller. Like following pseudo code to loop in the attributes from the AttributeCreator

 

    def input(self, feature):
      for attr in .pythoncreator.getAttribute:
            print(attr )
        self.pyoutput(feature)

 

 

 

 

 

 

 

 

You can use "feature.getAllAttributeNames()" to get a list of all the attribute names.

 

e.g., attlist=feature.getAllAttributeNames()

 

You can then use feature.getAttribute() in a loop like:

 

  for att in attlist:

          att_name = att

att_value = feature.getAttribute(att)

print(att_name)

print(att_value)

 

@virtualcitymatt​ is right, here's a code sample with indentation:

for attr_name in feature.getAllAttributeNames():
    attr_value = feature.getAttribute(attr_name)
    print('Attribute {} = {}'.format(attr_name, attr_value))

 You'll certainly also want to have a look at the fmeobjects documentation, found here: https://docs.safe.com/fme/html/fmepython/api/fmeobjects/_feature/fmeobjects.FMEFeature.html

Thanks for reply David but this is returning ALL Attributes in the workflow which I do not need them!

Attribute 1 = parks
Attribute 2 = swers
Attribute 3 = streets
Attribute 4 = schools
Attribute _creation_instance = 0
Attribute fme_feature_type = Creator
Attribute fme_geometry = fme_undefined
Attribute fme_type = fme_no_geom

and what I need is just this list from AttributeCreator

Attribute 1 = parks
Attribute 2 = swers
Attribute 3 = streets
Attribute 4 = schools

I checked the API but couldn't find out any parameter for fmeobjects.FMEFeature.getAllAttributeNames to limit this to only my specific AttributeCreator

Thanks

Indeed, fmeobjects does not keep track of which attribute was added or modified at which point in the workspace.

You can try and work around it by adding a prefix to the attributes you want to use. You can then remove this prefix in the python code​.
