Hi!
I am creating a plugin and I'm struglling on how to pass multiple datasets into the columnRole parametar in the JSON file. (I have two input datasets and I wanna have the option to select a column from either of the two and not just from one dataset):
"inputRoles" : [
{
"name": "first_dataset",
"label": "First Dataset",
"arity": "UNARY",
"required": true,
"acceptsDataset": true
},
{
"name": "second_dataset",
"label": "Second Dataset",
"arity": "UNARY",
"required": true,
"acceptsDataset": true
}
]
and here is the column:
{
"name": "partitioning",
"label": "unique identifier for a record",
"description": "",
"type": "COLUMN",
"allowedColumnTypes": [
"tinyint",
"smallint",
"int",
"bigint",
"string"
],
"columnRole": "first_dataset",
"mandatory": true
},
Thanks!!
Hi,
There is no way to pass multiple datasets in the columnRole field of the same parameter.
Instead, you could for instance create a SELECT parameter to choose from which dataset to select a column from, use 2 different parameters with 2 different columnRole corresponding to the 2 input datasets and display the right parameter in the UI based on the SELECT parameter using a visibilityCondition.
This would look like this:
{ "name": "selected_dataset", "label": "Input dataset to select a column from", "type": "SELECT", "defaultValue": "first_dataset", "selectChoices": [ { "value": "first_dataset", "label": "First dataset" }, { "value": "second_dataset", "label": "Second dataset" } ] }, { "name": "partitioning_first", "label": "unique identifier for a record", "description": "", "type": "COLUMN", "columnRole": "first_dataset", "visibilityCondition": "model.selected_dataset == 'first_dataset'" }, { "name": "partitioning_second", "label": "unique identifier for a record", "description": "", "type": "COLUMN", "columnRole": "second_dataset", "visibilityCondition": "model.selected_dataset == 'second_dataset'" }
@StanG Thank you so much!
