fill_usage_id works

Code
  dct_add_row(dct_add_row(tibble::tibble(taxonID = "123", scientificName = "Foogenus barspecies",
    taxonomicStatus = "accepted"), scientificName = "Bargenus foosp",
  taxonomicStatus = "accepted", acceptedNameUsageID = NA, stamp_modified = FALSE),
  scientificName = c("Foogenus boospecies", "Bargenus bkaspecies"),
  acceptedNameUsage = c("Foogenus barspecies", "Bargenus foosp"),
  taxonomicStatus = "synonym", stamp_modified = FALSE)
Output
  # A tibble: 4 x 5
    taxonID   scientificName taxonomicStatus acceptedNameUsageID acceptedNameUsage
    <chr>     <chr>          <chr>           <chr>               <chr>            
  1 123       Foogenus bars~ accepted        <NA>                <NA>             
  2 22aad276~ Bargenus foosp accepted        <NA>                <NA>             
  3 442c4d2d~ Foogenus boos~ synonym         123                 Foogenus barspec~

fill_usage_id only cares about uniqueness of matching names

Code
  dct_add_row(base_dat, scientificName = "Bargenus foosp", acceptedNameUsage = "Bargenus bkaspecies",
    taxonomicStatus = "synonym", stamp_modified = FALSE)
Output
  # A tibble: 4 x 5
    taxonID   scientificName taxonomicStatus acceptedNameUsage acceptedNameUsageID
    <chr>     <chr>          <chr>           <chr>             <chr>              
  1 1         Foogenus bars~ accepted        <NA>              <NA>               
  2 2         Foogenus bars~ accepted        <NA>              <NA>               
  3 3         Bargenus bkas~ accepted        <NA>              <NA>               
  4 22aad276~ Bargenus foosp synonym         Bargenus bkaspec~ 3

fill_usage_id doesn't create acceptedUsageID column when FALSE

Code
  dct_add_row(dct_add_row(tibble::tibble(taxonID = "123", scientificName = "Foogenus barspecies",
    taxonomicStatus = "accepted"), scientificName = "Bargenus foosp",
  taxonomicStatus = "accepted", stamp_modified = FALSE), scientificName = c(
    "Foogenus boospecies", "Bargenus bkaspecies"), acceptedNameUsage = c(
    "Foogenus barspecies", "Bargenus foosp"), taxonomicStatus = "synonym",
  stamp_modified = FALSE, fill_usage_id = FALSE)
Output
  # A tibble: 4 x 4
    taxonID                       scientificName taxonomicStatus acceptedNameUsage
    <chr>                         <chr>          <chr>           <chr>            
  1 123                           Foogenus bars~ accepted        <NA>             
  2 22aad27626cf8f945d4792dfceaa~ Bargenus foosp accepted        <NA>             
  3 442c4d2d5df6c3995a8d6a13d10c~ Foogenus boos~ synonym         Foogenus barspec~
  4 42e72bd3217967151e11da9d181a~ Bargenus bkas~ synonym         Bargenus foosp

setting validation args via options works

Code
  (expect_no_error(dct_add_row(base_dat, new_dat = add_dat, strict = TRUE)))
Output
  # A tibble: 2 x 5
    taxonID   scientificName acceptedNameUsageID acceptedNameUsage taxonomicStatus
    <chr>     <chr>          <chr>               <chr>             <chr>          
  1 1         foo            <NA>                <NA>              <NA>           
  2 bd40ef6d~ foo            <NA>                <NA>              <NA>
