Hi,
I was wondering if there is an api in Dataiku Python API to replace all the template literals in strings. DSS uses in many places a javascript like template literals, for example, in dataset you can define a path as:
/exports/${environment}/${projectKey}/customers
When I do not know what placeholders are used it is pretty complicated to parse out all the placeholders and then fetch those values from variables (assuming that get_custom_variables handles prioritization of local/standard/global vars)
It would be super useful to have something like:
client = dataiku.api_client()
client.evaluate_vars(dataset_path)
and it would replace all the known variables plus all the internal variables of DSS.
Thanks
Hi @tomas,
Definitely agree that it would be really nice to have a built-in method like you describe available in the API.
A less convenient but workable approach is to use the Python Template class. It turns out that the Template class handles the ${varname} format. Here is an example:
import dataiku
from string import Template
t = '/exports/${environment}/${projectKey}/customers'
e = Template(t).substitute(dataiku.get_custom_variables())
