Laravel relationships get user emails - php

Question

Hey from my website I'm sending multiple notifications to users, I'm assigning users to a team and then I assign this team to the notifications table.
However when I do SiteNotification::find(1)->notifications() then I get the name of the team, however, I was looking to get the user model and all the details related to that. Is there an easy way to obtain this using Laravel Eloquent relationships?
My DB model and Eloquent model are below;
DB tables;
User
id | username | email
Teams
id | name |
Team Members
team_id | user_id
Site Notifications
site_notification_id | team_id
Model Here:
class SiteNotification extends Model {
public function notifications()
{
return $this->belongsToMany(Team::class, 'site_check_notifications', 'site_check_id', 'team_id');
}
}
Update:
I've tried updating the Team Model as follows;
class Team extends Model
{
public function users()
{
return $this->hasManyThrough(
User::class,
TeamMember::class,
'team_id',
'id'
);
}
}
However this throws an error as follows when running this;
$site = Site::find(1);
foreach( $site->notifications as $notification) {
dd($notification->users);
}
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'team_members.id' in 'on clause' (SQL: select `users`.*, `team_members`.`team_id` from `users` inner join `team_members` on `team_members`.`id` = `users`.`id` where `team_members`.`team_id` = 4)
Any ideas what I'm doing wrong??

Answer 1

I've found a solution which has meant that I do not need to amend my existing database structure and I've found the correct relationship to use.
public function users()
{
return $this->belongsToMany(
User::class,
'team_members',
'team_id',
'user_id'
);
}
Now I can do Site::find(1)->users->pluck('email')

You have to change the model structure... This is how I would have reached your goal... Take it as a "working solution", maybe not the best!
First of all, database. You should have these tables, there is no need to
users => users table
teams => teams table
team_user => pivot table n:n
team_site_notification => pivot table n:n
site_notifications => notifications table
user_site_notification => pivot table n:n
Then you create the related models relations
public class User {
// [...]
public function teams() {
return $this->belongsToMany(Team::class)
}
public function notifications() {
return $this->belongsToMany(SiteNotification::class)
}
}
public class Team {
// [...]
public function users() {
return $this->belongsToMany(User::class)
}
public function notifications() {
return $this->belongsToMany(SiteNotification::class)
}
}
public class SiteNotification {
// [...]
public function teams() {
return $this->belongsToMany(Team::class)
}
public function users() {
return $this->belongsToMany(User::class)
}
}
In your controller, when you create the SiteNotification model, you'll have to associate also the users. For example
public function store(Request $request) {
// Do your stuff
$team = Team::findOrFail($request->your_team_id);
$notification = Notification::create($data);
$notification->teams()->associate($request->your_team_id);
// Retrieve the users from the team... Maybe not everyone should receive a notification
$team->users()->whereIn('id', $user_ids)->get()->pluck('id')
$notification->users()->associate($ids);
}
When you want to get your users list you simple retrive the associated users in this way:
dd($notification->users);
// [ User:{id: 1, '...'}, User:{id: 2}, User:{id: 7} ]
Hope this is what you're looking for!
