[WEBAPP] How to run a scenario with a local variable

Hi @Redouxne
,

Are you using a scenario variable or a project variable? Indeed, for scenario variables, it's only possible to set them from within the context of a scenario.

So, if you want to set a variable that will be used in a scenario but set it from a Webapp, you'll probably want to use a project variable instead. You can see the following code example for how to set a variable from the Python API, which can be run in the Python backend.

import dataiku 
client = dataiku.api_client()
project = client.get_default_project()

variables = project.get_variables()
variables['standard']['some_variable'] = 'some_value'    
project.set_variables(variables)

Then, from your scenario you can obtain this variable in a Python step:

import dataiku 
client = dataiku.api_client()
project = client.get_default_project()

variables = project.get_variables()
some_variable_value = variables['standard']['some_variable']

Let me know if this approach doesn't work for you!

Thank you,
