Question

I've one many to many relationship between Entities and Affiliated Tables, basically an affiliated can attend to many entities(example, medical services, dentist offices). One Entity can be visited by one or many affiliated. Additionaly , one or more benefits can be occupied by one affiliated in a particular entity. As shown in the image.

I want to be able to answer queries like, which benefits where used by the affiliated in a particular entity.

Should i create a new Model, how should i rewrite the many-to-many relationship for ORM.

Thanks in advance!

Answer 1

Don't need a Affiliated_has_Entities model. You could write the relationships as below, remember to check for arguments and its order in the belognsToMany relationship (sorry for misspelled words)

Entities model

public function afilliateds(){
return $this->belongsToMany('Afilliated', 'Afilliated_has_Entities');
}

Afilliated model

public function entities(){
return $this->belongsToMany('Entities', 'Afilliated_has_Entities');
}

public function benefits(){
return $this->belongsToMany('Entities', 'Afilliated_has_Entities');
}

Benefits model

public function entites(){
return $this->belongsToMany('Entities', 'Afilliated_has_Entities');
}

And so on..

I hope it helps
