I am performing a database operation with "Eloquent ORM in Laravel". I just want to take the last insert id (not the maximum id) in the database.
I searched to get last insert id in laravel Eloquent ORM, I got following link (Laravel, get last insert id using Eloquent) that is refer to get last insert id from following function "$data->save()".
But I need to get
"Model::create($data)";
My Query:
GeneralSettingModel::create($GeneralData);
User::create($loginuserdata);
How can I retrieve the last inserted id?
Like the docs say: Insert, update, delete
"You may also use the create method to save a new model in a single
line. The inserted model instance will be returned to you from the
method. However, before doing so, you will need to specify either a
fillable or guarded attribute on the model, as all Eloquent models
protect against mass-assignment.
After saving or creating a new model that uses auto-incrementing IDs,
you may retrieve the ID by accessing the object's id attribute:"
$insertedId = $user->id;
So in your sample:
$user = User::create($loginuserdata);
$insertedId = $user->id;
then on table2 it is going to be
$input['table2_id'] = $insertedId;
table2::create($input);
**** For Laravel ****
$user = new User();
$user->name = 'John';
$user->save();
//Getting Last inserted id
$insertedId = $user->id;
You could wrap your data in the insertGetId() method like this
$id = DB::table('table')->insertGetId( $data );
In this case the array $data would look something like this
$data = [ 'field' => 'data' , 'field' => 'data' ];
and if you’re using the DB façade you could just append the lastInsertID() method to your query.
$lastInsertedID = DB::table('table')->insert( $data )->lastInsertId();
$lastId = User::create($loginuserdata)->id;
As others said bfore me you may retrieve id by using
$model->id;
but only if you are using standard naming convention for eloquent. If you want to use other name for primaryKey column, eg:
class Users extends Model{
$primaryKey = 'userid';
}
you may retrieve last inserted id by calling
$model->userid;
It is described in: https://laravel.com/docs/master/eloquent#eloquent-model-conventions where one can find:
Eloquent will also assume that each table has a primary key column
named id. You may define a $primaryKey property to override this
convention.
In addition, Eloquent assumes that the primary key is an incrementing
integer value, which means that by default the primary key will be
cast to an int automatically. If you wish to use a non-incrementing or
a non-numeric primary key you must set the public $incrementing
property on your model to false.
You may do it as,
public function store(Request $request,ModelName $obj)
{
$lastInsertedId = $obj->create($request->all())->id;
}
Hope this will help you.
This is my try:
$model_ins = Model::orderBy('id', 'desc')->take(1)->first();
And use $model_ins->id.
This code works with Laravel 5.3:
$upstatus = User::create($status);
return response()->json($upstatus);
User pages/site I was call data.id
This is an eloquent model:
$user = new Reports();
$user->email= 'david#example.com';
$user->save();
$lastInsertId = $user->id;
A solution using Query Builder:
$lastInsertId = DB::table('reports')->insertGetId(['email' => 'david#example.com']);
$user = (new user)->create($request->all()) ;
\Session::flash('message', 'Thanks , Your record No (' .$user->id . ') has been Successfully added');
This is my solution. I return the inserted object and get its ID or any other property.
This is an easier way that works on all of the ways that you inserted:
DB::getPdo()->lastInsertId()

I have two tables, User and Post. One User can have many posts and one post belongs to only one user.
In my User model I have a hasMany relation...
public function post(){
return $this->hasmany('post');
}
And in my post model I have a belongsTo relation...
public function user(){
return $this->belongsTo('user');
}
Now I want to join these two tables using Eloquent with() but want specific columns from the second table. I know I can use the Query Builder but I don't want to.
When in the Post model I write...
public function getAllPosts() {
return Post::with('user')->get();
}
It runs the following queries...
select * from `posts`
select * from `users` where `users`.`id` in (<1>, <2>)
But what I want is...
select * from `posts`
select id,username from `users` where `users`.`id` in (<1>, <2>)
When I use...
Post::with('user')->get(array('columns'....));
It only returns the column from the first table. I want specific columns using with() from the second table. How can I do that?
Well I found the solution. It can be done one by passing a closure function in with() as second index of array like
Post::query()
->with(['user' => function ($query) {
$query->select('id', 'username');
}])
->get()
It will only select id and username from other table. I hope this will help others.
Remember that the primary key (id in this case) needs to be the first param in the
$query->select() to actually retrieve the necessary results.*
You can do it like this since Laravel 5.5:
Post::with('user:id,username')->get();
Care for the id field and foreign keys as stated in the docs:
When using this feature, you should always include the id column and
any relevant foreign key columns in the list of columns you wish to
retrieve.
For example, if the user belongs to a team and has a team_id as a foreign key column, then $post->user->team is empty if you don't specifiy team_id
Post::with('user:id,username,team_id')->get();
Also, if the user belongs to the post (i.e. there is a column post_id in the users table), then you need to specify it like this:
Post::with('user:id,username,post_id')->get();
Otherwise $post->user will be empty.
For loading models with specific column, though not eager loading, you could:
In your Post model
public function user()
{
return $this->belongsTo('User')->select(['id', 'username']);
}
Original credit goes to Laravel Eager Loading - Load only specific columns
When going the other way (hasMany):
User::with(['post'=>function($query){
$query->select('id','user_id');
}])->get();
Don't forget to include the foreign key (assuming it is user_id in this example) to resolve the relationship, otherwise you'll get zero results for your relation.
In Laravel 5.7 you can call specific field like this
$users = App\Book::with('author:id,name')->get();
It is important to add foreign_key field in the selection.
If you want to get specific columns using with() in laravel eloquent then you can use code as below which is originally answered by #Adam in his answer here in response of this same question, the answer's main code is as below :
Post::with('user:id,username')->get();
So i have used it in my code but it was giving me error of 1052: Column 'id' in field list is ambiguous, so if you guys are also facing same problem
Then for solving it you have to specify table name before the id column in with() method as below code:
Post::with('user:user.id,username')->get();
I came across this issue but with a second layer of related objects. #Awais Qarni's answer holds up with the inclusion of the appropriate foreign key in the nested select statement. Just as an id is required in the first nested select statement to reference the related model, the foreign key is required to reference the second degree of related models; in this example the Company model.
Post::with(['user' => function ($query) {
$query->select('id','company_id', 'username');
}, 'user.company' => function ($query) {
$query->select('id', 'name');
}])->get();
Additionally, if you want to select specific columns from the Post model you would need to include the user_id column in the select statement in order to reference it.
Post::with(['user' => function ($query) {
$query->select('id', 'username');
}])
->select('title', 'content', 'user_id')
->get();
In your Post model:
public function userWithName()
{
return $this->belongsTo('User')->select(array('id', 'first_name', 'last_name'));
}
Now you can use $post->userWithName
There is another alternative you can eager load specific columns
public function show(Post $post)
{
$posts = $post->has('user')->with('user:id,name,email,picture')->findOrFail($post->id);
return view('your_blade_file_path',compact('posts);
}
In your Post model you should have user relationship also
public function user()
{
return $this->belongsTo( User::class, 'user_id')->withDefault();
}
Note: It is mentioned in Laravel docs.
https://laravel.com/docs/8.x/eloquent-relationships#eager-loading-specific-columns
Note that if you only need one column from the table then using 'lists' is quite nice. In my case i am retrieving a user's favourite articles but i only want the article id's:
$favourites = $user->favourites->lists('id');
Returns an array of ids, eg:
Array
(
[0] => 3
[1] => 7
[2] => 8
)
If you use PHP 7.4 or later you can also do it using arrow function so it looks cleaner:
Post::with(['user' => fn ($query) => $query->select('id','username')])->get();
I faced the same issue while using belongsToMany relationship with my user model (Laravel 8.x.x).
After a long search and trial and test method. I found out this answer
You have to make sure you are selecting the id's and any foreign keys that would be needed for the relationship from either side of that relationship. This allows Eloquent to match up parents to their children.

So I included
Groups::select('groupid')
...
And it worked like a charm. Although now I want to know how to hide the groupid field after fetching.
I know I can simply loop through the array and remove it. But is there any other method? potentially a simpler and better one.
You can also specify columns on related model at the time of accessing it.
Post::first()->user()->get(['columns....']);
You can try this code . It is tested in laravel 6 version.
Controller code
public function getSection(Request $request)
{
Section::with(['sectionType' => function($q) {
$q->select('id', 'name');
}])->where('position',1)->orderBy('serial_no', 'asc')->get(['id','name','','description']);
return response()->json($getSection);
}
Model code
public function sectionType(){
return $this->belongsTo(Section_Type::class, 'type_id');
}
Be careful that if you don't add the key column(s) it won't return anything. If you want to show only the username without the id you could instead define the $visible/$hidden properties within the Model, like so:
app/Models/User.php
protected $visible = ['username'];
Then it will retrieve only username column with:
Post::with('user')->get();
Hiding the key columns:
Alternatively you could hide the key column(s) and then retrieve only the columns you wish.
app/Models/User.php
protected $hidden = ['id'];
Specify which columns you want including the key or else it won't return anything, but this will actually only return the username, because id is $hidden.
Post::with('user:id,username')->get();
Now you can use the pluckmethod on a Collection instance:
This will return only the uuid attribute of the Post model
App\Models\User::find(2)->posts->pluck('uuid')
=> Illuminate\Support\Collection {#983
all: [
"1",
"2",
"3",
],
}
Try with conditions.
$id = 1;
Post::with(array('user'=>function($query) use ($id){
$query->where('id','=',$id);
$query->select('id','username');
}))->get();
So, similar to other solutions here is mine:
// For example you have this relation defined with "user()" method
public function user()
{
return $this->belongsTo('User');
}
// Just make another one defined with "user_frontend()" method
public function user_frontend()
{
return $this->belongsTo('User')->select(array('id', 'username'));
}
// Then use it later like this
$thing = new Thing();
$thing->with('user_frontend');
// This way, you get only id and username,
// and if you want all fields you can do this
$thing = new Thing();
$thing->with('user');
EmployeeGatePassStatus::with('user:id,name')->get();
I am using Laravel and sqlsrv, connected to SQL Server 2016 and all is working great until I try to use an output clause in my insert query.
Query is something like
INSERT INTO TABLE(Columns) OUTPUT INSERTED.MyDesiredReturnColumn VALUES(Value)
This is working perfectly in SQL Server, and returning the desired value, but using Laravel's DB::insert functionality it is only returning a 1 (for successful insert)
I have a workaround that I would rather not have right now, using the CreatedOn field to return the most recently created row, but this has potential issues.
UPDATES: The field I am attempting to retrieve is a uniqueidentifier field (guid) that is created in SQL, not from Laravel-side
After attempting #PrathameshPalav's recommendation of using the Eloquent model creation, the values are being inserted correctly into the DB, but it is not returning the uniqueidentifier still.
$inserted = MyModel::create($information);
print "inserted id is " . $inserted->MyModelId;
This is printing "inserted id is "
Here is my model:
namespace App;
use Illuminate\Database\Eloquent\Model;
class MyModel extends Model
{
//
protected $table = 'MyModelBase';
protected $primaryKey = 'MyModelId';
public $incrementing = false;
protected $keyType = "string";
public $timestamps = false;
protected $fillable = ['field1', 'field2', 'etc'];
}
Any ideas would be greatly helpful.
You can use Eloquent ORM for this purpose:
$insertedObject = ModelName::create($input_array);
It will return inserted model object in response. Or if you want only inserted record id then use
DB::table($tablename)->insertGetId($input_array);
The way that I solved this was by incorporating an Eloquent model (as pointed out by #PrathameshPalav), then (loosely) following this tutorial https://danielkoch.work/log/laravels-eloquent-guids.html
Specifically this part
public static function boot() {
parent::boot();
// Hook when a model is created
static::creating(function ($model) {
// Select a new ID
$result = DB::select( DB::raw('Select NewID() NewUUID') );
$model->{$model->getKeyName()} = $result[0]->NewUUID;
});
}
After that, I added the primary key I had defined to the $fillable array and tested, and it works =)
Thank you both for your help!
Yes, when you use insert it will return a bool. You can use insertGetId to get the the id.
If the table has an auto-incrementing id, use the insertGetId method
to insert a record and then retrieve the ID:
$data = [....]; // data that will be inserted
$id = DB::table('xxx')->insertGetId($data);

In my controller I am defining a model and persisting it to the DB with save() :
$model = new Model();
$model->attrib = "something";
$model->save();
Ok so now I want to send this newly created data to my view like this:
return view('new_model', ['new_model' => $model]);
The problem is the data passes to the view but not the id assigned to the model in the DB.
How can I possibly send this data without performing a new query to the DB after the save();
Shouldn't the $model->save(); save to the DB and return what it persisted in the DB along id and all the stuff?
I stand corrected, the id was appearing at the end of the data.
$model->id should be the last id inserted.
Eloquent allows you to fill models by passing an associative array with values, and the keys representing the column names.
$model = Model::create([
'attrib' => 'something',
]);
You will get the id by $model->id.
Hope it works. :)
I have recently started working with Laravel and Eloquent, and was wondering about the lack of a find or create option for models. You could always write, for example:
$user = User::find($id);
if (!$user) {
$user = new User;
}
However, is there not a better way to find or create? It seems trivial in the example, but for more complex situations it would be really helpfully to either get an existing record and update it or create a new one.
Below is the original accepted answer for: Laravel-4
There is already a method findOrFail available in Laravel and when this method is used it throws ModelNotFoundException on fail but in your case you can do it by creating a method in your model, for example, if you have a User model then you just put this function in the model
// Put this in any model and use
// Modelname::findOrCreate($id);
public static function findOrCreate($id)
{
$obj = static::find($id);
return $obj ?: new static;
}
From your controller, you can use
$user = User::findOrCreate(5);
$user->first_name = 'John';
$user->last_name = 'Doe';
$user->save();
If a user with id of 5 exists, then it'll be updated, otherwise a new user will be created but the id will be last_user_id + 1 (auto incremented).
This is another way to do the same thing:
public function scopeFindOrCreate($query, $id)
{
$obj = $query->find($id);
return $obj ?: new static;
}
Instead of creating a static method, you can use a scope in the Model, so the method in the Model will be scopeMethodName and call Model::methodName(), same as you did in the static method, for example
$user = User::findOrCreate(5);
Update:
The firstOrCreate is available in Laravel 5x, the answer is too old and it was given for Laravel-4.0 in 2013.
In Laravel 5.3, the firstOrCreate method has the following declaration:
public function firstOrCreate(array $attributes, array $values = [])
Which means you can use it like this:
User::firstOrCreate(['email' => $email], ['name' => $name]);
User's existence will be only checked via email, but when created, the new record will save both email and name.
API Docs
Alternatively, in this case you can also use Laravel's function and search for id as an attribute, i.e.
$user = User::firstOrCreate(['id' => $id]);
Find or New based on primary key id
$user = User::findOrNew($id); // if exist then update else insert
$user->name= $data['full_name'];
$user->save();
First or New based on non-primary key single filed
// get the record where field_name=value else insert new record
$user = User::firstOrNew(['field_name'=>'value']);
$user->name= $data['full_name'];
$user->save();
First or New based on non-primary key multiple filed
// get the record where field_name1=value1 and field_name2=value2, else insert new record
$user = User::firstOrNew(['field_name1'=>'value1','field_name2'=>'value2']);
$user->name= $data['full_name'];
$user->save();
In Laravel 5:
There are two methods you may use to create models by mass assigning attributes: firstOrCreate and firstOrNew.
The firstOrCreate method will attempt to locate a database record using the given column / value pairs. If the model can not be found in the database, a record will be inserted with the given attributes.
The firstOrNew method, like firstOrCreate will attempt to locate a record in the database matching the given attributes. However, if a model is not found, a new model instance will be returned. Note that the model returned by firstOrNew has not yet been persisted to the database. You will need to call save manually to persist it:
// Retrieve the flight by the attributes, or create it if it doesn't exist...
$flight = App\Flight::firstOrCreate(['name' => 'Flight 10']);
// Retrieve the flight by the attributes, or instantiate a new instance...
$flight = App\Flight::firstOrNew(['name' => 'Flight 10']);
Laravel 4 models have a built-in findOrNew method that does what you need:
$user = User::findOrNew($id);
You can use firstOrCreate (It's working with Laravel 4.2)
$bucketUser = BucketUser::firstOrCreate([
'bucket_id' => '1',
'user_id' => '2',
]);
returns found instance or new instance.
