Combine validator outputs

evalidators() combines the output of several validators into the format used by DataEntry inspectors. Rows with the same variable and reason are grouped together, and their rowid values are collapsed into a comma-separated string.

Usage

evalidators(
  L,
  msg =
    "Inspector validation failed. Open the inspectors table and check the inspector definition."
)

Arguments

L

A list of validator outputs. Each element should contain at least rowid, variable, and reason.

msg

Fallback validation message used when validator outputs cannot be combined or do not contain rowid, variable, and reason.

Value

A data.table with columns variable, reason, and rowid when validation succeeds. If validation fails, a data.frame with rowid, variable, and reason.

Details

If the validator outputs cannot be combined, evalidators() returns a validator-shaped error explaining that the inspector failed.

Examples

L = list(
  data.table::data.table(rowid = c(1, 2), variable = "a", reason = "missing"),
  data.table::data.table(rowid = 3, variable = "a", reason = "missing"),
  data.table::data.table(rowid = 2, variable = "b", reason = "invalid")
)

evalidators(L)
#>    variable  reason  rowid
#>      <char>  <char> <char>
#> 1:        a missing  1,2,3
#> 2:        b invalid      2
