Multiple SELECT parameters using getChoicesFromPython ?

Hi Mariat,

It seems like the structure of your json file (I assume a recipe.json file?) is not the proper one.

It should be something like this:

{

...

"paramsPythonSetup": "computechoices.py",
"params": [
{

"type": "SELECT",
"name": "param_1",

"label": "label description",
"getChoicesFromPython": true

}
],

...

}

You can have a look at the documentation here: https://doc.dataiku.com/dss/latest/plugins/reference/params.html#dynamic-select-using-python

Hope this helps,

Agathe

It seems the Python code you provided is not valid.

You could retry with this code instead:

def do(payload, config, plugin_config, inputs):
    if payload.get('param2') == 'a' and payload.get('param3') == 'b':
        choices = [
            {"value": "x", "label": "X"},
            {"value": "y","label": "Y"}
        ]
        return {"choices": choices}

    if payload.get('param2') == 'a' and payload.get('param3') == 'c':
        choices = [{"value": "z", "label": "Z"}]
        return {"choices": choices}

Please notice that this code does not handle the case where param2 is not a and param3 is neither b nor c, so the dropdown would be left unpopulated in this scenario. Unsure if this is desired/by design.

Hi again,

I am sorry, I was too focused on fixing the small syntax errors of the snippet code and did not pay enough attention to the actual content. We indeed need to make small minor changes in it to match your use case.

Assuming that you want to dynamically change the options for param1 based on the values taken by param2 and param3, with param2 and param3 taking their respective options from a static list given in your recipe.json file via the field selectChoices, the following code should do it properly:

def do(payload, config, plugin_config, inputs):
    if config.get('param2') == 'a' and config.get('param3') == 'b':
         choices = [
            {"value": "x", "label": "X"},
            {"value": "y","label": "Y"}
        ]
        return {"choices": choices}

    if config.get('param2') == 'a' and config.get('param3') == 'c':
        choices = [{"value": "z", "label": "Z"}]
        return {"choices": choices}

" height="20" loading="lazy">"> However, some disclaimers apply here:

1. Notice that if param2 is not a or param3 is neither b nor c, the dropdown for param1 will not be populated. If this is the intended behavior, you can use directly the code I provided above.

2. The ability to update custom dropdowns in a plugin recipe from the values of other dropdowns (custom or not) is available since 9.0.5 release only

Hope this helps!
