Create unique buffers in Notebook

Hello

I have an AGOL item with 3 layers: Site Location (pts), Site Buffer (poly) and Site Area (poly). The Site Area has a field with a Distance value that I would like to use to create my buffers (different value for each area).

So in my Notebook, I have a piece of code that select all the Site Location where the BufferFlag='N' then I intersect each of the records with my Site Area to get the proper value of the Distance to create the buffer…. AND THEN I AM STUCK! below is the section of code that I can't figure it out.(line 15 to 20)

i=0 ###for each Site Location WORKING for f in SLHFLcount: print(f.attributes['FUID'] + ' -- '+ f.attributes['BufFlag2']) ptFeat = SLHFLcount.features[i].geometry print(ptFeat) print("~~~~~~~~~") ###Intersect with my Site Location WORKING AreaHFLqry = AreaHFL.query(where='1=1', geometry_filter=filters.intersects(ptFeat)) print(len(AreaHFLqry)) if len(AreaHFLqry) >=1: AreaHFLqryFeatures = AreaHFLqry.features print(AreaHFLqryFeatures[0].attributes['Area1']+ ' -- '+ AreaHFLqryFeatures[0].attributes['Area2'] + ' -- '+ str(AreaHFLqryFeatures[0].attributes['Dist'])) ###Create individual buffers NOT WORKING dDist = AreaHFLqryFeatures[0].attributes['Dist'] buffLyr = use_proximity.create_buffers(SLHFL, distances=[dDist], units = 'Feet',output_name=BufferHFL) #buffLyr_fc = buffLyr.layer #print(buffLyr_fc) map1.add_layer(BufferHFL) ###update BufFlag to Y #strExpression = "FUID='"+str(f.attributes['FUID']+"'") #SLHFL.calculate(where=strExpression,calc_expression={"field":"BufFlag2", "value": "Y"}) else: print("we don't have a polygon yet") i +=1 print("----------------") print("Process completed")

How can I create the buffer JUST for that selected Site Location and append the buffer to my Site Buffer layer?

Any help would be much appreciated.

Thanks!

Ok I solved my own problem:

1) I added a Filter on my Feature layer to get one Site Location the time

fExpression = "FUID='" + f.attributes['FUID'] +"'" SLHFL.filter = fExpression

and then , after I ran the buffer I am adding the new feature to my Buffer Layer using the following code

buffLyr = use_proximity.create_buffers(SLHFL, distances=[dDist], units = 'Feet') #Append to Buffer HFL BufferHFL.edit_features(adds=buffLyr.layer.featureSet.features)

working great!
