When you create a brand new project you have users table and User model already by default. So, now create another table with model: php artisan make:model Role -m This will create Role model as well as roles table. Now as it is many to many relation. So we need a pivot table. Pivot table naming convention: role_user Here role is written first as because alphabetically r comes before u. and laravel eloquent relationship takes in this way. So, you should remember this always. and use _ in between role and user. like: role_user So, let's create role_user table. php artisan make:migration create_role_user_table --create=role_user naming covention of pivot says that role_user table is singular. users table includes: id name, email pivot table role_user includes: user_id role_id roles table includes: id name migrate it all. Many to Many Relation: Go to User model and write: public function roles(){  r...

Suppose you have two tables: users and posts tables. users table includes: id ,name,email posts table includes: id,title,body, user_id One to many relationship: Go to User model and write: public function posts(){  return $this->hasMany('App\Post'); } Look at the function naming convention. It's plural as it is one to many relationship. Store: $user->posts()->save($post); Here, $user variable comes from findorfail($id). and $post variable has taken the requested data from user. I haven't shown all of this in details here as it is only to understand how one to many relationship actually works. Show: foreach($user->posts as $post){    echo $post->title."<br>"; } Update: $user->posts()->where('id','=',2)->update(['title'=>'your updated title','body'=>'your updated body'); Delete: $user->posts->whereId(1)->delete(); To delete all t...

One to one relationship: Suppose you have two tables users and addresses: Users table: id ,name,email Addresses table: id,name, user_id In the address table the user_id will come from the users table. Be careful about the naming convention. Your Model name is User so table name is users so to get id from users table to addresses table you have to write according to the model name in the field of address like user_id . So to declare one-to-one relationship: Just think that user can have only one address. So,  go to User model and write: public function address(){  return $this->hasOne('App\Address'); } here as this is one to one we are using singular function name which is address(). Store: $user->address()-> save($address); [Here, $user is finding the user by id, and $address is saving the requested address] Show: To show the address name $user->address->name; Update: $address = Address::whereUserId(1)->first(); $address...

When you run php artisan tinker on your shell/command prompt you often/rarely get this error but this can cause because of composer. so close your opened tinker and run: composer dump-autoload and again run php artisan tinker and create your data. 

This mass assignment error occurs when you don't declare protected or guarded to your model. so, just write protected $fillable=[              'name', ]; or, protected $guarded=[]; both are same. $guarded is the opposite of $fillable but acts the same. but if you put name inside $guarded like: $guarded =['name'], than it will only guard this means it will not allow you to give data to name. so, living guarded blank is same as protected $fillable =['name'];
