Laravel HasOneTHough & Laravel HasManyThough Relationships
We generally know about the 4 basics Laravel Relations ships that laravel provides:
Now we are going to see the major missing relationships that we are thinking are “Hard to use”, but in real cases, it’s needed while developing a project.
Even though I was thinking that HasOneThough and HasManyThough Relationships were will be hard to understand, I was wrong. it’s really easy to understand.
Understanding HasOneThough
Let’s say there is a Library that wants to know the book issuer’s name directly, in this case, we generally do :
- Fetch Books
- Fetch its related issuer by using the HasOne Relation
What if I say I can directly access the issuer name into the Library model, yes we can achieve this by using the has one though.
Library
- id
- name
Book
- id
- name
- library_id
Issuer
- id
- name
- book_id
public function issuer() {
return hasOneThough(App\Issuer, App\Book, library_id, book_id)
}
Understanding HasManyThough
Let’s say in the same example that there are multiple issuers of the same books, we can achieve it as follow.
public function issuer() {
return hasManyThough(App\Issuer, App\Book, library_id, book_id)
}
Hope it will be helpful.
Thanks
