Prepare Values

prepare.Rd

Turn trigger values into tabular data.

Usage

prepare(values, config, update = FALSE, item = get_context())

Arguments

values

a named list of values (see details).

config

the config list.

update

a logical if values are used in the update workflow (default FALSE).

item

optional (see details), the name (id) of the item group.

Value

a data.frame

Details

values is a named list. The names are used to check the corresponding values vs the data.model (class, default values if the provided ones are not valid). The elements in the list must have either length one or same length as the id element.

When an element has length one but the id has several values, all items corresponding to these ids will be updated with same value. To do so, values will be turned into a data.frame using as.data.frame ; for this reason, it's strongly advised to wrap the call into tryCatch() as this may fail.

When item is set in the parent frame, then the attribute can be skipped in the function call.
