Laravel 8 : How to create a Pivot Model with its associated migration? - laravel

Question

I would like to create a model: FormsUser and the migration: forms_user
To use the table as a pivot because I have problems when I create a forms I am told that the table: 'forms_users does not exist' because I created the migration separately and
when I go to my group members management page I get the error: 'forms_users does not exist' because here I have to use a pivot table so it must have this table name...
Can you help me to solve this problem or suggest an alternative?
in short I want to create a forms and I create a team where I can add other user to the same forms.
migration: forms && Models Forms :
class Forms extends Model
{
use HasFactory;
use SoftDeletes;
protected $fillable = [
'title',
'description',
'date',
'color',
'progress',
'user_id',
'groupe_id',
'formulaire',
'logo',
];
protected $dates = [
'created_at',
'deleted_at',
'started_at',
'update_at'
];
public function user()
{
return $this->belongsTo(User::class);
}
public function usersGroupe()
{
return $this->belongsToMany(User::class);
}
}
migration: users && Models User:
class User extends Authenticatable
{
use HasApiTokens;
use HasFactory;
use HasProfilePhoto;
use Notifiable;
use TwoFactorAuthenticatable;
use SoftDeletes;
/**
* The attributes that are mass assignable.
*
* #var string[]
*/
protected $fillable = [
'lastname',
'firstname',
'email',
'password',
'current_team_id',
'profile_photo_path',
'role_id',
];
/**
* The attributes that should be hidden for serialization.
*
* #var array
*/
protected $hidden = [
'password',
'remember_token',
'two_factor_recovery_codes',
'two_factor_secret',
];
/**
* The attributes that should be cast.
*
* #var array
*/
protected $casts = [
'email_verified_at' => 'datetime',
];
/**
* The accessors to append to the model's array form.
*
* #var array
*/
protected $appends = [
'profile_photo_url',
'role_id',
];
protected $dates = [
'created_at',
'deleted_at',
'started_at',
'update_at'
];
public function forms()
{
return $this->hasMany(Forms::class);
}
public function formGroupe()
{
return $this->belongsToMany(Forms::class);
}
public function role()
{
//return $this->hasMany(Role::class, 'id', 'role_id');
return $this->hasOne(Role::class, 'id', 'role_id');
}
public function user()
{
return $this->hasOne(User::class);
}
}
migration: formuser && Models FormsUser :
class FormsUser extends Model
{
use HasFactory;
protected $fillable = [
'forms_id',
'user_id'
];
}
migration create_forms_user :
Schema::create('forms_user', function (Blueprint $table) {
$table->id();
$table->timestamps();
$table->unsignedBigInteger('forms_id');
$table->foreign('forms_id')->references('id')->on('forms');
$table->unsignedBigInteger('user_id');
$table->foreign('user_id')->references('id')->on('users');
});

Answer 1

So traditionally you don't have to create a pivot model. Laravel has some naming conventions that if you stick to will make things a bit easier. For example, Models should be singular but table names should be plural except for the pivot table. For example, your models should look like so:
class User extends Model { ... }
class Form extends Model { ... }
Then your table names would be :
users
forms
form_user
The pivot table should include the singular name of each table in alphabetical order. So F comes before U in the alphabet so it should read form_user.
Lastly in your Form model you would include a 'belongsToMany' function:
public function users() {
return $this->belongsToMany('App\User');
}
and in the User Model you would include the same in reverse:
public function forms() {
return $this->belongsToMany('App\Form');
}
If you entered the migrations correctly you will never need to create a pivot model. You can simply call the other objects through the relation to retrieve an array. ie:
$user->forms
$form->users

After a lot of hard work I was finally able to solve the problem so instead of storing the data via the Models pivot I did it directly via a request to the migration.
Anyway, thanks for your participation.
Problem solved!
