Relationships, and specifically Eloquent Relationships, are a really popular feature of Laravel. * Example: return $this->belongsTo(Post::class, 'post_id', 'id') There unfortunately isnt a way to pass an array of relationships to has () or whereHas (), but you can use a QueryScope instead. * Example: return $this->hasMany(Comment::class, 'post_id', 'id') īelongsTo(Post::class, 'foreign_key', 'owner_key') HasMany(Comment::class, 'foreign_key', 'local_key') we will also use "hasMany()" and "belongsTo()" for relationship of both model. Here, we will create Post and Comment table model. $table->foreignId('post_id')->constrained('posts') In fact theres no reason why a specific Many-to-one relationship couldnt be created in parallel with the many-to-many. we will also add foreign key with posts table.

For example, a blog post may have an infinite number of comments. A and B have many to many relation through AB table. A one-to-many relationship is used to define relationships where a single model owns any amount of other models. both tables are connected with each other. I have one interesting problem in Laravel database. Retrieving relationships of relationships using Eloquent in Laravel. In this example, I will create a "posts" table and a "comments" table.
