usually you define this using the foreign key in your database

->onDelete('cascade');

Thank you so much for your respond! But sadly isn't working, I have 2 tables RootInformation and Participant. At the RootInformation model already had this

    public function participant(): HasMany
    {
        return $this->hasMany(Participant::class,'idRootInfo','id');
    }

    public function participant(): HasMany
    {
        return $this->hasMany(Participant::class,'idRootInfo','id');
    }

at the Participant model

    public function RootInformation(): BelongsTo
    {
        return $this->belongsTo(RootInformation::class, 'id');
    }

    public function RootInformation(): BelongsTo
    {
        return $this->belongsTo(RootInformation::class, 'id');
    }

works fine when using repeater relationship. but now when want to delete data from RootRelationship table, the participant not follow to deleted.

RootInformation migration:

<?php
        Schema::create('root_information', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->boolean('gender');
            $table->text('address');
            $table->string('phoneNumber');
            $table->string('email');
            $table->string('instituteName');
            $table->foreignId('idPriceCategory');
            $table->string('proofPayment')->nullable();
            $table->boolean('isVerified')->default(0)->nullable();
            $table->timestamps();
        });
    }

<?php
        Schema::create('root_information', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->boolean('gender');
            $table->text('address');
            $table->string('phoneNumber');
            $table->string('email');
            $table->string('instituteName');
            $table->foreignId('idPriceCategory');
            $table->string('proofPayment')->nullable();
            $table->boolean('isVerified')->default(0)->nullable();
            $table->timestamps();
        });
    }

participants migration

<?php
        Schema::create('participants', function (Blueprint $table) {
            $table->id();
            $table->foreign('idRootInfo')->references('id')->on('RootInformation')->onDelete('cascade');
            $table->string('nameParticipant');
            $table->boolean('genderParticipant');
            $table->date('dobParticipant');
            $table->text('addressParticipant');
            $table->string('phoneNumberParticipant');
            $table->string('emailParticipant');
            $table->string('instituteNameParticipant');
            $table->string('pickupParticipant');
            $table->foreignId('idClassChoice');
            $table->timestamps();
        });
    }

<?php
        Schema::create('participants', function (Blueprint $table) {
            $table->id();
            $table->foreign('idRootInfo')->references('id')->on('RootInformation')->onDelete('cascade');
            $table->string('nameParticipant');
            $table->boolean('genderParticipant');
            $table->date('dobParticipant');
            $table->text('addressParticipant');
            $table->string('phoneNumberParticipant');
            $table->string('emailParticipant');
            $table->string('instituteNameParticipant');
            $table->string('pickupParticipant');
            $table->foreignId('idClassChoice');
            $table->timestamps();
        });
    }

does this work? .. shouldn't it be "root_information" .. can you see that the the foreign key is created properly in your db tool ?

mvenghaus•3mo ago

because it's not filament or laravel model methods who delete's the data .. it's the database
