There are multiple ways to prevent duplicates in Laravel Eloquent:

  1. Define unique constraints in your database schema for the columns that should not have duplicate values. You can do this using migrations in Laravel.
  2. Use the unique validation rule in Laravel's form request validation to validate the uniqueness of values before storing them in the database.
  3. Use the firstOrCreate method to check if a record with the same values already exists before creating a new one. This method will either return the existing record or create a new one if it doesn't exist.
  4. Use the updateOrCreate method to update an existing record if it already exists, otherwise create a new one.
  5. Use the save method with the exists property set to false to prevent the creation of duplicates when updating records.


By using these methods, you can effectively prevent duplicates in your Laravel Eloquent models.
