I am want to update my records in my database using Eloquent model. I am having an error in updating user_profile table that saying where id is not null.
User Model
class User extends Model
{
public function profile()
{
return $this->hasOne('App\Models\Common\UserProfile');
}
}
UserProfile Model
class UserProfile extends Model
{
public function user()
{
return $this->belongsTo('\App\Models\User');
}
}
Controller
$user->fill($data);
$user->save();
$user->profile->fill($data);
$user->profile->save();
In MySQL query it looks like this:
UPDATE users, user_profiles
SET users.name='Test Name',
user_profiles.email='test#gmail.com'
WHERE users.id=1
AND user_profiles.user_id=1;
I know MySQL query but I'm new to Eloquent and I want to do it in Eloquent model. Maybe there are some in here that can provide an explanation on how the magic works in Eloquent.
By default eloquent assumes, that any model has an id column as primary key. If that is not the case, you need to "register" the primary key with
protected $primaryKey = 'user_id';
in the model class.

I have two models (see below). With a one to many relationship, the HasMany relationship is working as expected, but the inverse belongsTo doesn't get any results when I try to do this.
$user = Auth::user();
dd($user->location->name);
I have the following database structure
Table locations
id
name
slug
Table users
id
name
email
password
location_id
remember_token
App/User model
public function location() {
return $this->belongsTo( 'App\Models\Location' );
}
and the App\Models\Location model
public function users()
{
return $this->hasMany('App\User');
}
I've got a strange problem.
I've a users table and a company table. A User belongsTo a company and a company hasMany users.
Both primary keys of the table are id.
In the laravel documentation I read the following:
Additionally, Eloquent assumes that the foreign key should have a
value matching the id column of the parent.
I've got this in my CompanyModel:
protected $table = 'company';
public function users()
{
return $this->hasMany(UserModel::class);
}
When I try this:
$users = CompanyModel::find(1)->users;
dd($users);
It's not working. When I add a foreign key in my relation it works!?:
protected $table = 'company';
public function users()
{
return $this->hasMany(UserModel::class, 'id');
}
This is strange right? What on earth am I doing wrong.
--EDIT--
In my users table I've got a company_id column!
Firstly, I would suggest you rename your Model from CompanyModelto Company and from UserModel to User.
Then ensure you have company_id in your users table. And in your users migration file connect the users table with the companies table as such:
$table->integer('company_id')->unsigned();
$table->foreign('company_id')->references('id')->on('companies')->onDelete('cascade');
Don't forget to refresh your database.
Then in your models, define the relationships as such:
// User model
// Laravel will automatically identify and use the `company_id` field in your reference
public function company(){
return $this->belongsTo(Company::class);
}
// Company model
public function users(){
return $this->hasMany(User::class);
}
You can then fetch your records in your controller as such:
$user = User::find(1);
$user_company = $user->company; // This might not be necessary in your controller, you can do it in your view
dd($users, $user_company);
I have two models User and UserType declared as follows:
class User extends Model {
protected $table = 'user';
protected $primaryKey = 'user_id';
public function company() {
return $this->hasOne('App\Models\Company', 'company_id', 'company_id');
}
public function userType() {
return $this->hasOne('App\Models\UserType', 'user_type_id', 'user_type_id');
}
}
class UserType extends Model {
protected $table = 'user_type';
protected $primaryKey = 'user_type_id';
}
Now, I query the relationships using:
User::with('userType', 'company')->all()
Strangely, I get the company but userType is always null.
The MySQL query log shows that Laravel was able to get the user_type record.
The only difference between company and userType relationships are the data type of the primary keys. company.company_id is numeric while user_type.user_type_id is a string.
I think it is related to the data type of the keys however, I have a similar setup on Laravel 5.1 and it runs perfectly.
Laravel supports non-numeric primary keys but you need to set:
public $incrementing = false;
on your model class.
I corrected the issue by changing UserType definition to:
class UserType extends Model {
protected $table = 'user_type';
protected $primaryKey = 'user_type_id';
public $incrementing = false;
}
The first issue i notice with your relationship is that the first user_type_id you have passed to the hasOne function is wrong because you have the user_type_id as the primary key of the user_type table. The second argument of the hasone must be the foreign key of the parent table which is the user. So if you have anything like user_id in the user_type table use that instead.
But if thats not the case and user rather belongs to UserType then you have to change the hasOne to belongsTo.
laravels authentication system uses Id by default ,but lets say you have a bigger database with many tables how do you specify lets say the customer table
$user = User::where('name', '=', $name);
if($user->count()) {
$user=$user->first();
$user->status= 'super';
if($user->save()) {
return Redirect::route('home')
}
}
If your primary key is named differently than id you can configure the column name in the model:
class User extends Model implements AuthenticatableContract, CanResetPasswordContract {
protected $primaryKey = 'customer_id';
}
It's all in the documentation:
Note: Eloquent will also assume that each table has a primary key column named id. You may define a primaryKey property to override this convention. Likewise, you may define a connection property to override the name of the database connection that should be used when utilizing the model.
This is what my schema looks like.
Schema:
User
id
email
password
firstname
lastname
Profile
user_id (foreign key)
name
weight
height
Model
I have a one to many relationship for the models.
User
class User extends Eloquent implements UserInterface, RemindableInterface {
public function Profiles()
{
return $this->hasMany('Profile');
}
Profile
class Profile extends Eloquent {
public function user()
{
return $this->belongsTo('User', 'user_id', 'id');
}
Problem
I realized that creating a separate name field in my Profile is already redundant to the firstname & lastname in User.
I plan to create a Profile property called name that is just referenced from the User model.
Any help on accomplishing this? Would appreciate any advice.
Thanks!
