My bad, I was on my phone and I didn't see the full image on my phone and I thought you were after project variables. Here you go. Given these recipe variables:
{ "var1": 1, "var2": "Some New Text", "var3": true }
import dataiku client_handle = dataiku.api_client() project_handle = client_handle.get_project('PROJECT_KEY') recipe_handle = project_handle.get_recipe('recipe_name') recipe_settings = recipe_handle.get_settings() recipe_definition = recipe_settings.get_recipe_raw_definition() for variable in recipe_definition['variables']: print(variable + ' Value: ' + str(recipe_definition['variables'][variable]))
Gives me:
var1 Value: 1 var2 Value: Some Text var3 Value: True
Then changing it:
recipe_handle = project_handle.get_recipe('compute_customers_out') recipe_settings = recipe_handle.get_settings() recipe_definition = recipe_settings.get_recipe_raw_definition() recipe_definition['variables']['var2'] = "Some New Text" recipe_settings.save() for variable in recipe_definition['variables']: print(variable + ' Value: ' + str(recipe_definition['variables'][variable]))
Output:
var1 Value: 1 var2 Value: Some New Text var3 Value: True

Hi @Turribeach
,You cannot use `get_custom_variables`, did you mean something else in the link you sent?

Very close, but on DSS 11 I get this error:

You forgot to change the recipe name on the second recipe_handle assignment. The first 3 lines on the save part are redundant if you are already reading the values. But I included them in case you just wanted to save a variable.
Personally I think it's a bug since the Dataiku API is not returning any errors on "project_handle.get_recipe('unknown_recipe')". But if you run "recipe_handle.get_status()" you will get the expected exception:DataikuException: com.dataiku.dip.server.controllers.NotFoundException: recipe does not exist: TEST_PROJECT.dummy_recipe
