Laravel: Validation unique on update

👋 Hey there, tech enthusiasts! 🖥️

Are you a Laravel developer struggling with the validation unique on update issue? 🤔 Don't worry, you're not alone. Many developers have faced this common problem but found it hard to figure out how to pass the ID when validating in the model. 😥

In this blog post, I'll explain how to solve this dilemma and provide you with easy solutions. 💡 So, let's dive right in! 🏊‍♂️

First, let's take a look at the code snippet that sparked this question:

'email' => 'unique:users,email_address,10'

The above line shows a validation rule that checks if the email address is unique in the users table. But what if you want to update an existing record and need to exclude the current email address from the uniqueness check? 🤷‍♂️

To pass the ID of the record to the validation rule, you can make use of Laravel's model accessor. 🧙‍♂️

Here's an example of how you can modify your models/User code:

protected $rules_update = [
    'email_address' => 'required|email|unique:users,email_address,'.$id,
    'first_name' => "required",
    'last_name' => "required",
    'password' => "required|min:6|same:password_confirm",
    'password_confirm' => "required:min:6|same:password",
    'password_current' => "required:min:6"
];

In the line 'email_address' => 'required|email|unique:users,email_address,'.$id,, the $id variable should contain the ID of the record you want to update. By appending it to the unique rule, Laravel knows to exclude that record from the uniqueness check. 🙌

Now, let's take a look at the models/BaseModel code:

protected $rules = array();

public $errors;

public function validate($data, $rules = "rules") {
    $validation  = Validator::make($data, $this->$rules);

    if($validation->passes()) {
        return true;
    }

    $this->errors = $validation->messages();

    return false;
}

In the above code, you can customize the validate method in your BaseModel to pass your custom rules when validating. This way, you can easily handle the validation process in one central place. 🎯
