I know this question has been asked many times before but no one explains how to get the id when you're validating in the model.
'email' => 'unique:users,email_address,10'
My validation rule is in the model so how do I pass the ID of the record to the validation rule.
Here is my models/User
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"
];
models/BaseModel
protected $rules = array();
public $errors;
/*
* #data: array, Data to be validated
* #rules: string, rule name in model
*/
public function validate($data, $rules = "rules") {
$validation = Validator::make($data, $this->$rules);
if($validation->passes()) {
return true;
}
$this->errors = $validation->messages();
return false;
}
Just a side note, most answers to this question talk about email_address while in Laravel's inbuilt auth system, the email field name is just email. Here is an example how you can validate a unique field, i.e. an email on the update:
In a Form Request, you do like this:
public function rules()
{
return [
'email' => 'required|email|unique:users,email,'.$this->user->id,
];
}
Or if you are validating your data in a controller directly:
public function update(Request $request, User $user)
{
$request->validate([
'email' => 'required|email|unique:users,email,'.$user->id,
]);
}
Update:
If you are updating the signed in user and aren't injecting the User model into your route, you may encounter undefined property when accessing id on $this->user. In that case, use:
public function rules()
{
return [
'email' => 'required|email|unique:users,email,'.$this->user()->id,
];
}
A more elegant way since Laravel 5.7 is:
public function rules()
{
return [
'email' => ['required', 'email', \Illuminate\Validation\Rule::unique('users')->ignore($this->user()->id)]
];
}
P.S: I have added some other rules, i.e. required and email, in order to make this example clear for newbies.
One simple solution.
In your Model
protected $rules = [
'email_address' => 'sometimes|required|email|unique:users',
..
];
In your Controller, action:update
...
$rules = User::$rules;
$rules['email_address'] = $rules['email_address'] . ',id,' . $id;
$validationCertificate = Validator::make($input, $rules);
There is an elegant way to do this. If you are using Resource Controllers, your link to edit your record will look like this:
/users/{user}/edit OR /users/1/edit
And in your UserRequest, the rule should be like this :
public function rules()
{
return [
'name' => [
'required',
'unique:users,name,' . $this->user
],
];
}
Or if your link to edit your record look like this:
/users/edit/1
You can try this also:
public function rules()
{
return [
'name' => [
'required',
'unique:users,name,' . $this->id
],
];
}
From Laravel 5.7, this works great
use Illuminate\Validation\Rule;
Validator::make($data, [
'email' => [
'required',
Rule::unique('users')->ignore($user->id),
],
]);
Forcing A Unique Rule To Ignore A Given ID:
Test below code:
'email' => 'required|email|unique:users,email_address,'. $id .'ID'
Where ID is the primary id of the table
If i understand what you want:
'email' => 'required|email|unique:users,email_address,'. $id .''
In model update method, for exemple, should receive the $id with parameter.
Sorry my bad english.
Here is the solution:
For Update:
public function controllerName(Request $request, $id)
{
$this->validate($request, [
"form_field_name" => 'required|unique:db_table_name,db_table_column_name,'.$id
]);
// the rest code
}
That's it. Happy Coding :)
The Best Option is here try just once no need more code when unique validation on updating data
'email' => 'unique:users,email_address,' . $userId,
hereemailis field name and users is table name and email_address is table attribute name which you want unique and $userid is updating row id
public function rules()
{
switch($this->method())
{
case 'GET':
case 'DELETE':
{
return [];
}
case 'POST':
{
return [
'name' => 'required|unique:permissions|max:255',
'display_name' => 'required',
];
}
case 'PUT':
case 'PATCH':
{
return [
'name' => 'unique:permissions,name,'.$this->get('id').'|max:255',
'display_name' => 'required',
];
}
default:break;
}
}
an even simpler solution tested with version 5.2
in your model
// validator rules
public static $rules = array(
...
'email_address' => 'email|required|unique:users,id'
);
You can try this.
protected $rules_update = [
'email_address' => 'required|email|unique:users,email_address,'. $this->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 Laravel 8.x you can use Rule::unique method as well
Forcing A Unique Rule To Ignore A Given ID:
use Illuminate\Validation\Rule;
public function update(Request $request, Post $post)
{
$validatedData = $request->validate([
'name' => ['required', 'max:60', Rule::unique('posts')->ignore($post->id)],
]);
$post->update($validatedData);
return redirect(route('posts.index'))->with('status', 'post updated successfully');
}
Do One step in controller
Works Fine with Laravel 9
$request->validate([
'name'=>'required|unique:categories,name,'.$id,
]);
If you have a separate rules method. You can use easier the following syntax.
public function rules()
{
return [
'email' => "required|unique:users,email,{$this->id}"
];
}
$rules = [
"email" => "email|unique:users, email, '.$id.', user_id"
];
In Illuminate\Validation\Rules\Unique;
Unique validation will parse string validation to Rule object
Unique validation has pattern: unique:%s,%s,%s,%s,%s'
Corresponding with: table name, column, ignore, id column, format wheres
/**
* Convert the rule to a validation string.
*
* #return string
*/
public function __toString()
{
return rtrim(sprintf('unique:%s,%s,%s,%s,%s',
$this->table,
$this->column,
$this->ignore ?: 'NULL',
$this->idColumn,
$this->formatWheres()
), ',');
}
There is a simple and elegant way to do this. If you are passing the user_id in a body request or through a query parameter.
e.g
/update/profile?user_id=
Then in your request rules
public function rules(Request $request)
{
return [
'first_name' => 'required|string',
'last_name' => 'required|string',
'email' => ['required','email', 'string', Rule::unique('users')->ignore($request->user_id )],
'phone_number' => ['required', 'string', Rule::unique('users')->ignore($request->user_id )],
];
}
Better Still, you can pass in auth->id() in place of $request->user_id to get the login user id.
Found the easiest way, working fine while I am using Laravel 5.2
public function rules()
{
switch ($this->method()) {
case 'PUT':
$rules = [
'name' => 'required|min:3',
'gender' => 'required',
'email' => 'required|email|unique:users,id,:id',
'password' => 'required|min:5',
'password_confirmation' => 'required|min:5|same:password',
];
break;
default:
$rules = [
'name' => 'required|min:3',
'gender' => 'required',
'email' => 'required|email|unique:users',
'password' => 'required|min:5',
'password_confirmation' => 'required|min:5|same:password',
];
break;
}
return $rules;
}
i would solve that by doing something like this
public function rules()
{
return [
'name' =>
'required|min:2|max:255|unique:courses,name,'.\Request::get('id'),
];
}
Where you get the id from the request and pass it on the rule
You can also use model classpath, if you don't want to hard code the table name.
function rules(){
return [
'email' => ['required','string',
Rule::unique(User::class,'email')->ignore($this->id)]
];
}
Here $this->id is either 0 or the record Id to be updated.
Use for Laravel 6.0
use Illuminate\Validation\Rule;
public function update(Request $request, $id)
{
// Form validation
$request->validate([
'category_name' => [
'required',
'max:255',
Rule::unique('categories')->ignore($id),
]
]);
}
After researching a lot on this laravel validation topic including unique column, finally got the best approach. Please have a look
In your controller
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Validator;
class UserController extends Controller
{
public function saveUser(Request $request){
$validator = Validator::make($request->all(),User::rules($request->get('id')),User::$messages);
if($validator->fails()){
return redirect()->back()->withErrors($validator)->withInput();
}
}
}
saveUser method can be called for add/update user record.
In you model
class User extends Model
{
public static function rules($id = null)
{
return [
'email_address' => 'required|email|unique:users,email_address,'.$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"
];
}
public static $messages = [
'email_address.required' => 'Please enter email!',
'email_address.email' => 'Invalid email!',
'email_address.unique' => 'Email already exist!',
...
];
}
This is what I ended up doing. I'm sure there is a more efficient way of doing this but this is what i came up with.
Model/User.php
protected $rules = [
'email_address' => 'sometimes|required|email|unique:users,email_address, {{$id}}',
];
Model/BaseModel.php
public function validate($data, $id = null) {
$rules = $this->$rules_string;
//let's loop through and explode the validation rules
foreach($rules as $keys => $value) {
$validations = explode('|', $value);
foreach($validations as $key=>$value) {
// Seearch for {{$id}} and replace it with $id
$validations[$key] = str_replace('{{$id}}', $id, $value);
}
//Let's create the pipe seperator
$implode = implode("|", $validations);
$rules[$keys] = $implode;
}
....
}
I pass the $user_id to the validation in the controller
Controller/UserController.php
public function update($id) {
.....
$user = User::find($user_id);
if($user->validate($formRequest, $user_id)) {
//validation succcess
}
....
}
While updating any Existing Data Write validator as following:
'email' => ['required','email', Rule::unique('users')->ignore($user->id)]
This will skip/ignore existing user's id's unique value matching for the specific column.
Test below code:
$validator = Validator::make(
array(
'E-mail'=>$request['email'],
),
array(
'E-mail' => 'required|email|unique:users,email,'.$request['id'],
));
Since you will want to ignore the record you are updating when performing an update, you will want to use ignore as mentioned by some others. But I prefer to receive an instance of the User rather then just an ID. This method will also allow you to do the same for other models
Controller
public function update(UserRequest $request, User $user)
{
$user->update($request->all());
return back();
}
UserRequest
public function rules()
{
return [
'email' => [
'required',
\Illuminate\Validation\Rule::unique('users')->ignoreModel($this->route('user')),
],
];
}
update: use ignoreModel in stead of ignore
Very easy to do it ,
Write it at your controller
$this->validate($request,[
'email'=>['required',Rule::unique('yourTableName')->ignore($request->id)]
]);
Note : Rule::unique('yourTableName')->ignore($idParameter) , here $idParameter you can receive from get url also you can get it from hidden field.
Most important is don't forget to import Rule at the top.
If a login user want to update the email then auth() helper function will give us the login user id auth()->user()->id
Laravel helpers#method-auth
Validator::make($data, [
'email' => [
'required',
Rule::unique('users')->ignore(auth()->user()->id),
],
]);
if Admin want to change the specific user information from User list then validation will be like this :
Validator::make($data, [
'email' => [
'required',
Rule::unique('users')->ignore($request->user),
],
Laravel validation#rule-unique
$request object contain the current route related model objects. Which gives the model.
Try dd($request)
Most answers to this question refer to email_address, but in Laravel's inbuilt authentication system, the email field name is just email. Here is an example of validating a unique field, i.e. an email on the update:
Form Requests look like this:
public function rules()
{
return [
'email' => [ 'required','email', Rule::unique('users')->ignore($this->id ?? 0)]];
}
?? 0 If you use this then if hare id does not exist this request will not give you an error
Save
Whenever you access the id property of $this->user, you may encounter an undefined property if you haven't injected the User model into your route. If that is the case, use:
public function rules()
{
return [
'email' => 'required|email|unique:users,email,'.$this->user()->id ?? 0,
];
}
?? 0 If you use this then if hare id does not exist this request will not give you an error
My solution:
$rules = $user->isDirty('email') ? \User::$rules : array_except(\User::$rules, 'email');
Then in validation:
$validator = \Validator::make(\Input::all(), $rules, \User::$messages);
The logic is if the email address in the form is different, we need to validated it, if the email hasn't changed, we don't need to validate, so remove that rule from validation.
For unique rule in the controller - which obviously will be different for the store method and the update method, I usually make a function within the controller for rules which will return an array of rules.
protected function rules($request)
{
$commonRules = [
'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"
];
$uniqueRules = $request->id
//update
? ['email_address' => ['required', 'email', 'unique:users,email' . $request->get('id')]]
//store
: ['email_address' => ['required', 'email', 'unique:users,email']];
return array_merge($commonRules, $uinqueRules);
}
Then in the respective store and update methods
$validatedData = $request->validate($this->rules($request));
This saves from defining two different rule sets for store and update methods.
If you can afford to compromise a bit on readability, it can also be
protected function rules($request)
{
return [
'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",
'email_address' => ['required', 'email', 'unique:users,email' . $request->id ?: null]
];
}
I'm developing an API with Laravel. In one of the endpoint I'm accessing, some fields are showing a null value, but it should have some information.
Note the "addicionais_descricao" and "valor" fields, both always come with null values when I include them in the attributeitems array, but if I leave it at the initial level, the data is presented, but it doesn't solve my case, because I need this information with the attribute items:
enter image description here
This is where the endpoint calls, I make the query in the "Attribute" table, which has a relationship with the "Attributeitems" table, while the "attributeitems" table is linked to "Attribute" and "product".
public function show($id)
{
$atributos = Atributo::query('atributo')
->select(
'atributo.id',
'atributo.atrdescricao',
'atributoitens.atributo_id',
'atributoitens.produto_id',
'produto.prodescricao',
'produto.provalor'
)
->leftJoin('atributoitens', 'atributo.id', '=', 'atributoitens.atributo_id')
->leftJoin('produto', 'produto.id', '=', 'atributoitens.produto_id')
->where('atributo.id', '=', $id)
->get()->unique('id');
return AtributoResource::collection($atributos);
}
Resource Atributo:
public function toArray($request)
{
return [
'id' => $this->id,
'descricao' => $this->atrdescricao,
'atributoitens' => AtributoitensResource::collection($this->atributoitens),
];
}
Resource Atributo Itens:
public function toArray($request)
{
return [
'id' => $this->id,
'atributo' => $this->atributo_id,
'produtos' => $this->produto_id,
'adicionais_descricao' => $this->prodescricao,
'valor' => $this->provalor
];
}
What is the correct procedure for this situation?
Take this example as a reference :
Controller
$data = $shop->products()
->whereStatus(true)
->where('product_shop.active', true)
->where('product_shop.quantity', '>=', $this->min_product_qty)
->paginate(50);
return (new ProductCollection($data))
->response()
->setStatusCode(200);
ProductCollection
public function toArray($request)
{
return [
'data' => $this->collection
->map(function($product) use ($request) {
return (new ProductResource($product))->toArray($request);
}),
'brand' => $this->when($request->brand, $request->brand)
];
}
ProductResource
public function toArray($request)
{
return [
'type' => 'product',
'id' => (string) $this->id,
'attributes' => [
'uuid' => $this->uuid,
'name' => $this->name,
'slug' => $this->slug,
'description' => $this->description,
'thumb_path' => $this->thumb_path,
'cover_path' => $this->cover_path,
],
'relationships' => [
'brand' => $this->brand
]
];
}
Something like this should help you do what you want. I cant exactly do it for you. by the way why you are not using Eloquent, something like
Attribute::where(...)->with(['relation_1', 'products'])->get();
public function toArray($request)
{
return [
'id' => $this->id,
'attributes' => [...],
'products' => $this->collection
->map(function($this->product) use ($request) {
return (new ProductResource($product))->toArray($request);
}),
];
}
I have a users table which has a unique validate rule on email and username. When i am trying to update not ignore unique validation. Please see my code below.
UserRequest.php
public function rules()
{
return [
'name' => 'required',
'mobile' => 'required',
'email' => 'required|unique:users,email'.$id,
'usercategory' => 'required',
'username' => 'required|unique:users,username'.$id,
];
}
Please try this
public function rules()
{
$id = $this->request->get('id') ? ',' . $this->request->get('id') : '';
return [
'name' => 'required',
'mobile' => 'required',
'email' => 'required|unique:users,email'.$id,
'usercategory' => 'required',
'username' => 'required|unique:users,username'.$id,
];
}
In laravel 5.5 you should do like this:
use Illuminate\Validation\Rule;
Validator::make($data, [
'email' => [
'required',
Rule::unique('users')->ignore($user->id),
],
]);
Check laravel documentaion about rule-unique.
You needed to skip id if you validate for update, like as below
public function rules($id='')
{
$id = $id ? ','.$id.',id':'';
return [
'name' => 'required',
'mobile' => 'required',
'email' => 'required|unique:users,email'.$id,
'usercategory' => 'required',
'username' => 'required|unique:users,username'.$id,
];
}
In Laravel docs, you have provide 3rd and 4th param in unique rule
unique:table,column,except,idColumn
You could use something like this:
$id = $this->isMethod('put') ? ',' . auth()->id() : '';
assuming you use put method for update
before line with return
for somebody else faced this issue:
public function rules()
{
return [
'name' => 'required',
'mobile' => 'required',
'email' => 'required|unique:users,email'.$this->user->id,
'usercategory' => 'required',
'username' => 'required|unique:users,username'.$this->user->id,
];
}
I fixed this by using this:
public function rules()
{
$id = $this->user->id ?? null;
return [
"name" => "required",
"mobile" => "required",
"email" => "required|unique:users,email, $id",
"usercategory" => "required",
"username" => "required|unique:users,username, $id",
];
}
Note that for other models other than the User model, the user in $this->user->id will be the model name in lowercase
