Question

I have the Below Table Structure
Users table
id- integer
name-string
Casefiles table
id- integer
user_id- foreign_key
name-string
Followups table
id- integer
date- date
casefile_id-foreign_key
I'm using the below Relationship between this models
User.php
public function casefiles()
{
if ($this->hasRole(['sales_executive'])) {
return Casefile::where('user_id', $this->id);
}
}
Casefile.php
public function user()
{
return $this->belongsTo('App\User');
}
public function followups()
{
return $this->hasMany('App\FollowUp');
}
Followup.php
public function casefile()
{
return $this->belongsTo('App\Casefile');
}
I want to fetch Users followups directly. How can i achive this ?

Answer 1

you need to use hasManyThrough() in your User.php you can add this,
public function followUps()
{
return $this->hasManyThrough('App\FollowUp','App\Casefile');
}
then you can normally call the followups using User::with('followUps')->find(1)->followUps
I have noticed that you are checking role in your relationship $this->hasRole(['sales_executive'] this may occur error as you are not if the statement is false. I think you take another approached and handle that as well. for more information on hasManyThrough prefer this link

Answer 2

This should be the case for a HasManyThrough Relationship.
In your case it should be
// Followups migration
Schema::create('followups', function (Blueprint $table) {
$table->bigIncrements('id');
$table->date('date');
$table->unsignedBigInteger('casefile_id')->nullable();
$table->timestamps();
$table->foreign('casefile_id')
->references('id')
->on('casefiles');
});
// Casefile migration
Schema::create('casefiles', function (Blueprint $table) {
$table->bigIncrements('id');
$table->string('name');
$table->unsignedBigInteger('user_id')->nullable();
$table->timestamps();
$table->foreign('user_id')
->references('id')
->on('users');
});
// User.php
public function followups() {
return $this->hasManyThrough(FollowUp::class, Casefile::class);
}
// YourController.php
$user = User::all()->first();
dd($user->followups);
