Review details
Suppressed comments (3)
cmd/mapping/mapping.go:26
- The command group currently registers only
validate, so this help text claims functionality thatfga mapping testandfga mapping rundo not provide. Describe only the implemented subcommand until those commands are added.
Long: "Validate, test, and run JSON-to-tuple mapping files.",
cmd/mapping/validate.go:173
- The new
--verbosebranch is not covered byvalidate_test.go: every test callsvalidateMapping(..., false, ...), so both the documented success checkmarks and per-rule failure formatting can regress unnoticed. Add focused coverage forverbose=true, including a model-inconsistency case.
if verbose {
for _, rule := range compiled.Rules() {
fmt.Fprintf(out, " ✓ %s\n", rule.Name)
}
cmd/mapping/validate_model.go:242
- This only verifies that the condition name exists globally, not that the target object relation permits that condition. In a model such as
example/model_abac.fga, a condition is attached to a relation via[user with condition]; applying that condition to another existing relation should be rejected, but this code accepts it. Validate the condition against the object type/relation metadata as well.
cond, exists := idx.conditions[tmpl.Condition]
if !exists {
return fmt.Errorf("rule %q: condition %q: %w", ruleName, tmpl.Condition, errConditionNotInModel)
}

Inline comments:
In `@cmd/mapping/mapping.go`:
- Line 26: Update the Long description for the mapping command to advertise only
the currently registered subcommand, validateCmd; do not mention test or run
unless those subcommands are implemented and registered in init.
In `@cmd/mapping/validate.go`:
- Around line 202-204: Remove the os.Exit(2) calls from validateCmd.RunE while
preserving the errMappingInvalid and errModelInconsistent error results. Update
cmd.Execute’s centralized error-to-exit-code handling to map both errors to exit
code 2, and add command-level tests covering each failure.
In `@README.md`:
- Line 1218: Fix the invalid command links in the README command table: update
or remove the `#init-mapping` link at README.md lines 1218-1218, `#test-mapping` at
lines 1220-1220, and `#run-mapping` at lines 1221-1221 so each points to an
existing heading or has no link.

- Accept zero or one positional args; when missing on an interactive TTY, prompt to stderr. Non-interactive environments get a hard error (exit 2). - Return exit code 2 for unsupported --format values (was exit 1). - Register -v shorthand for --verbose via BoolVarP. - Update integration test case 005 to expect exit code 2.
Break long lines in RunE and flag registration, add missing blank line
to satisfy wsl, replace ptr helper with openfga.PtrString, and use any
instead of interface{} in test.

Replace bufio.Scanner with charmbracelet/huh for the TTY path prompt, giving a richer interactive input experience. Add huh to the depguard allowlist and go.mod/go.sum.
…ssignee check Print the error message to stderr before exiting with code 2 when an unsupported --format is passed; previously the command exited silently. Fix isValidAssignee to accept a skipConditionCheck flag. tuple_filter entries carry no condition field and must match if the user type is assignable under any condition; the previous code passed empty string as the condition, causing relations defined as [user with <cond>] to be incorrectly rejected on the filter path.
Description
What problem is being solved?
The CLI has no tooling for mapping files — the YAML files that define how a JSON payload maps to FGA tuples.
How is it being solved?
A new
fga mappingcommand group is introduced, starting withfga mapping validate. The command compiles a mapping file and optionally checks that every tuple template is consistent with a given authorization model.What changes are made to solve it?
