Eloquent ORM is Object Relational Mapper enables us to define relationship with model, such that once relationship is defined we can perform database manipulation without explicit query.
Relationship type -:
- Polymorphic one-to-one/one-to-many
2.create new database in mysql(blog)
3.update db details in config/database.php
Example : schema
Here post_id is the foreign_key of Post_Content, So in order to create the relation, first we need to create the model
Now we can access the data using $blog->blog_content
For each blog there is only a single author and a single author can have many post(one-to-*).
And now let’s establish one-to-* relation using hasMany function.
$blog_author->post we get all the post of a single author.Here we need to get the author details of a single post,for each post there a a single author, within the Post model include belongsTo relation.
In Post, we get the details of author using $post->author->author_name
In Author we can loop through all the post of an author using $author->post
Each post have many tag and each tag can have many post.
Laravel Model Relationships
Here all the above methods used to read data , While creating a new post we need to insert data to Post, Content,Author etc we can perform this using query builder save()
$post = Post::create(array(‘title’ => Input::get(‘title’));// insert into table post
$text = Text::create(array(‘text’ => Input::get(‘text’)); // insert into table content
This article includes the fundamentals of Eloquent ORM model. Eloquent ORM implementation is really fast and the interaction with the database is very simple.
