Magic ETL Python script
in Dataflows
Hello. I can't find any example to run a Magic ETL Python script.
I have added a column. I want to populate it with a pythons script and it never works
in the schema tab I have added a new text column named : "Alias" and here is my script :
# Import the domomagic package into the script from domomagic import * # read data from inputs into a data frame input1 = read_dataframe('dataset') # write your script here # i dont know how to add a property "Alias" to input1 : here is what i have tried : input1["Alias"] = "test" # write a data frame so it's available to the next action write_dataframe(input1)
I know I can achieve it with a simple "Add constants" but I would like to know how to use python script.

Have you looked at the schema tab on the script tile? Does it appear after you run a preview? https://knowledge.domo.com/Prepare/Magic_Transforms/ETL_DataFlows/ETL_Actions%3A_Scripting#Populating_The_Resulting_Schema
