In `@API.md`:
- Around line 8-14: Update the API docs to match the implemented route: change
the documented endpoint from "GET /healthcheck" to "GET /health" in API.md so it
aligns with the registered handler (the actual route registered as GET /health
in main). Ensure the heading and any example request paths reflect "/health" and
keep the existing response body unchanged.
- Around line 75-101: The POST /api/users endpoint conflicts with the
verify-token flow and will cause DB constraint violations because it calls
DB.Create() without checking for existing users; either remove POST /api/users
entirely (relying on POST /api/verify-token and FindOrCreateUser) or convert it
to an admin-only endpoint by adding an admin privilege check and replacing the
DB.Create() call with the shared FindOrCreateUser logic so it safely handles
existing users; update any route handler named for POST /api/users and ensure
auth/authorization checks (admin flag) are enforced if you keep the endpoint.
In `@controllers/users.go`:
- Around line 46-48: The DB.Create(&user) call in controllers/users.go ignores
errors and can return invalid data to clients; update the CreateUser flow to
check the result := models.DB.Create(&user) (or use tx :=
models.DB.Create(&user)) and if result.Error != nil return an appropriate HTTP
error via c.JSON (e.g., http.StatusBadRequest or http.StatusInternalServerError)
with the error message/context, and avoid returning the user on failure; also
handle result.RowsAffected if needed for additional validation.

In `@controllers/users.go`:
- Around line 16-17: In FindUsers, the GORM query currently calls
models.DB.Find(&users) with users typed as []models.UserResponse which causes
GORM to target the wrong table (user_responses) and hides failures; change the
query to use models.DB.Model(&models.User{}).Find(&users) to explicitly target
the users table, add proper error handling on the result (check result.Error and
handle non-nil by logging and returning an appropriate non-200 HTTP response),
and ensure the handler returns the expected payload only on success; keep types
as []models.UserResponse for response mapping but query from
Model(&models.User{}).

In `@models/users.go`:
- Around line 34-47: FindOrCreateUser currently treats any DB error as "not
found" and proceeds to create a user; change the logic to only enter the create
path when the query error is gorm.ErrRecordNotFound (use errors.Is(result.Error,
gorm.ErrRecordNotFound)). If result.Error is non-nil and not ErrRecordNotFound,
immediately return nil and the error instead of creating a new User; keep the
existing DB.Create(&user) and error logging for the actual create path. Make
sure to reference result.Error, gorm.ErrRecordNotFound, FindOrCreateUser, and
DB.Create when applying the fix.

FindUsers queries with the wrong table due to DTO type mismatch—fix by using .Model(&models.User{}) and add error handling.
On Line 17, models.DB.Find(&users) uses []models.UserResponse as the destination. GORM's default naming convention (SnakeCase) infers the table name from the struct type, so this targets user_responses instead of users. Additionally, UserResponse is never migrated (only User and FCMToken are in AutoMigrate), so the query will fail silently. The missing error handler also means failures return HTTP 200 with empty data.
Use .Model(&models.User{}) to explicitly target the correct table and add error handling:
Proposed fix
func FindUsers(c *gin.Context) {
var users []models.UserResponse
- models.DB.Find(&users)
+ result := models.DB.Model(&models.User{}).
+ Select("id, first_name, last_name, email").
+ Find(&users)
+ if result.Error != nil {
+ c.JSON(http.StatusInternalServerError, gin.H{"error": "Failed to fetch users"})
+ return
+ }
c.JSON(http.StatusOK, gin.H{"data": users})
