class pixeltable.ConfigVar

A reference to a database variable or secret, declared at module scope. A declaration names the variable; the target it is applied to supplies the value. Declare a variable and apply it to a column:

MEDIA_DEST = pxt.ConfigVar(‘media_dest’, pxt.URI) … … … class Videos(TableModel, name=‘videos’): … clip = pxt.Column(value=…, destination=MEDIA_DEST)

Code that runs on the target reads the bound value with value().

method value()

Signature

value() -> ConfVarT

The bound value, converted to the declared type. Raises if the target has no binding for it. Examples: Read a secret from a udf, which runs on the target:

@pxt.udf
def summarize(text: str) -> str:
    return _call(text, key=API_KEY.value())
