already four days now, still have not reslove this challenge-CodePudding

What am i not doing right? i'm woking on a livewire project that needs to get the grade_id's to show in show-component.blade.php, from Modules table which is related to a Grades table. My challenge is that, it only show a particular id, like the one in the mount section, so if i change it to 2 it will only show id's that are 2's, though thats really what i wanted but i can be change it manually.

use App\Models\Grade;
use App\Models\Module;
use Livewire\Component;

class ShowComponent extends Component
{
    public $modules;
    public $grades;

    public function mount()
    {
        $this->modules = Module::all()->where("grade_id", "1");

    }

    public function render()
    {
       return view('livewire.show-component');
    }
}

show-component.blade.php

@foreach($modules as $module)
        <div >

CodePudding user response：

If you want all Module records stored in your database table, you want to remove the where condition which is limiting the return value.

$this->modules = Module::all();

If you want just the grade_ids from your modules table, use pluck:

$grade_ids = Module::pluck('grade_id');

CodePudding user response：

I think what you want is ..

Add

public $grade_id;

Then in mount

$this->modules = Module::where("grade_id", $this->grade_id)->get();

When you load your component you can pass grade_id to it
