How to retrieve child data without timestamp in Laravel

Database tables mostly related to one another. For example, a post may have many comments or an order that can be related to the person who placed it. Eloquent makes it easier to retrieve child data, and supports a variety of common relationships like:


The most basic relationship. If a User model is associated with one Phone model. To define this relationship, we will place a phone method on the User model. The phone method should call the hasOne method and return its result. The hasOne method is available to your model as shown below:

 public function phone()
        return $this->hasOne(Phone::class);


If we have Authors and Books, with 1-n (one-to-many) relationship – one Author can have one or many Books. Here’s how the code looks:

public function books()
        return $this->hasMany(Book::class, 'author_id');


The inverse of a hasMany relationship, define a relationship method on the child model which calls the belongsTo method. We use it as shown below.

public function post()
        return $this->belongsTo(Post::class);

Has One of Many

Used when you want to retrieve the “latest” or “oldest” related model of the relationship. For example, a User model may be related to many Order models, but you want to define a convenient way to interact with the most recent order the user has placed. The code below shows how to relation can be used.

public function latestOrder()
    return $this->hasOne(Order::class)->latestOfMany();

One of the functionality of these Eloquent relations is to filter parents by whether they have or don’t have children. They help manage, work, and retrieve child data using with these relationships,
