### Design Patterns
* create folder app/Repository
* create 2 files      TeacherRepositoryInterface.php , RepositoryInterface.php
* create Provider and register 2 files in it    pa make:provider name
* open config/app  and register provider here
* make construct in controller for call design patterns


### soft Delete
* $table->softDeletes();   // in migration table
* use SoftDeletes;         // in model
* student::all()  == student::onlyTrashed()->get();
* when column in db  deleted_at is null  this meaning no anything have soft delete and when have timezone meaning softdelete done 
  * can use two   restore();   forceDelete();
    * look in StudentGraduatedRepository.php


### Froginkey
   ```
    # instead of
    
        $table->unsignedBigInteger('teacher_id');
        $table->foreign('teacher_id')->references('id')->on('teachers')->onDelete('cascade');
    
    # use foreignId
                $table->foreignId('Classroom_id')->references('id')->on('classrooms')->onDelete('cascade');

   ```

 # Multi Auth guards
```
 *1--> guard  config/auth      
        # guard single  and table (s)
 2--> provider/RouteServiceProvider
 3--> middelware/RedirectIfAuthenticated
    # if user enter email and password correct what it do routing where
 4--> middelware/Authenticate
    # if user enter email and password wrong what it do routing where
 5--> //Auth::routes();
 6--> use only login form page not 4 login page
 7--> edit Http/Controllers/Auth/LoginController.php
 8--> add this in model  # class Student extends Authenticatable
