naming tables in many to many relationships larave

Question

I concerned about auto naming tables in many-to-many Laravel relationship.

for example:

Schema::create('feature_product', function (Blueprint $table) {

when change the table name to:

Schema::create('product_feature', function (Blueprint $table) {

I have an error in my relationship.

What's the matter with product_feature?

Laravel's naming convention for pivot tables is singularized table names in alphabetical order separated by an underscore. So, if one table is features, and the other table is products, the pivot table will be feature_product.

You are free to use any table name you want (such as product_feature), but you will then need to specify the name of the pivot table in the relationship. This is done using the second parameter to the belongsToMany() function.

// in Product model
public function features()
{
    return $this->belongsToMany('App\Feature', 'product_feature');
}

// in Feature model
public function products()
{
    return $this->belongsToMany('App\Product', 'product_feature');
}
