See the Validation documentation of Laravel.

Specify different column names in the database

e.g. your input contains a field 'last_name', but the column in your database is called 'sur_name':

Ignore existing row (useful when updating)

You can also specify a row id to ignore (useful to solve unique constraint when updating)

This will ignore row with id 2

If your id is not numeric, you can tell the validator

Add additional clauses (e.g. when using soft deletes)

You can also set additional clauses. For example, if your model uses soft deleting then you can use the following code to select all existing rows but marked as deleted

Soft delete caveat:

In Laravel 5 (tested on 5.5), if the validation is performed in form request class, field deleted_at is skipped, because it's not send in request. To solve this problem, add 'deleted_at' => null to Your validation parameters in request class., e.g.:

Specify specific database connection to use
