Php 我怎么能在一段拉维关系中多次使用同一型号？

我正在开发一个应用程序，在这个程序中，用户可以进行附加培训，并进行一些描述。 因此，他们可以在高中接受培训，并附上“Rockford高中”的描述。然而，我希望他们能够把几次相同的类型，所以他们可以有3个高中，或大学等

但是，当我尝试使用相同id附加两次相同的模型时，其中一个会被覆盖。我认为使用中间模型可以解决这个问题，但事实并非如此

这是我的迁移和任何相关代码

称我为白痴，但我认为这样的话对你的情况来说是有意义的：

Schema::create('trainings', function (Blueprint $table) {
    $table->id();
    $table->string('name_french');
    $table->string('name_english'); 
    // You should checkout 'spatie/laravel-translatable' package, that 
    // way you can use one column for 'name' and then translate it in realtime
    // depending on your application locale.
    $table->timestamps();
});

Schema::create('candidate_practice', function (Blueprint $table) {
   $table->id();
   $table->string('candidate_id');
   $table->string('training_id');
   $table->timestamps(); // Probably not needed
});

Schema::create('practices', function (Blueprint $table) {
   $table->id();
   $table->foreignId('candidate_id')
         ->constrained()
         ->onDelete('cascade');
   $table->string('description');
   $table->timestamps();
});

Schema::create('candidates', function (Blueprint $table) {
    $table->id();
    $table->string('first_name');
    $table->string('last_name');
    $table->string('email');
    $table->string('phone_number');
    $table->string('address');
    $table->string('field_of_work')->default('{}');
    $table->string('formations')->default('{}');
    $table->string('work_experiences')->default('{}');
    $table->string('interests')->default('{}');
    $table->string('cv')->default('');
    $table->string('video_cv')->default('');
    $table->timestamps();
});

现在，您可以通过一对多关系创建与用户相关的多个实践，该关系更易于单独编辑或删除，而无需使用其他资源，然后将实践与培训关联起来

这样，就不再需要创建
CandidatePractice.php
pivot类了。
我们需要查看附加培训的代码？这是可行的：）
