How define relation hasManyThrough - php

Question

I have tables:
users
- id
- name
- company_id
companies
- id
- company_name
watched_objects
- id
- user_id
- object_id
- type
Now I want to get all watched companies for a user.
So query should looks:
SELECT
companies.*
FROM companies
JOIN watched_objects ON watched_objects.object_id = companies.id
WHERE watched_objects.user_id = 1
How should I define relations?
I try this:
class User
{
public function watched()
{
return $this->hasManyThrough('App\Company', 'App\WatchedObject', 'user_id', 'id');
}
}
But query is:
SELECT
companies.*,
watched_objects.user_id
FROM companies
INNER JOIN watched_objects ON watched_objects.id = companies.id
WHERE watched_objects.user_id = 1
How I can change watched_objects.id to watched_objects.object_id.

Answer 1

If your treating object_id as company id, then the relation is considered to be many to many. Then table watched_objects will be the third table kept the relation of user and company.
class User {
public function watched() {
return $this->belongsToMany('App\Company', 'watched_objects', 'user_id', 'object_id');
}
}
In order to find the watched companies of user 1, you can use the following code.
$watched_companies = User::find(1)->watched;

Answer 2

To get all watched companies by a user you can do like this:
$watches=WatchedObject::where(['user_id'=>Auth::user()->id])->with('company')->get();
foreach($watches as $watch)
{
print_r($watch->company->company_name);
}
Relation:
Company hasMany watched objects:
public function watches()
{
return $this->hasMany('App\WatchedObject','object_id');
}
and belongsTo in watchedObject Model:
public function company()
{
return $this->belongsTo('App\Company','object_id');
}
