laravel where on relationship table - php

Question

I am using laravel, I have a main table with 'projects' and a table with 'users', an intermediate table linking the two as a many-to-many relationship.
Now I want to display a list of projects, but if they are over 'projects.max_people' then they should be hidden from this list, how do I do this in laravel?
The problem is im 'get()'ing the users in the view, after I did Project::get()... how do I add this where condition?

Answer 1

You should create a new object called ProjectUser or so. In this object should contain a 'project_id' and 'user_id'.
Then, your Project model would look something like this:
<?php
class Project extends \Eloquent
{
protected $table = 'projects';
public function projectUsers(){
$this->hasMany('ProjectUser', 'project_id');
}
}
The User class:
<?php
class Project extends \Eloquent
{
protected $table = 'projects';
public function projectUsers(){
$this->hasMany('ProjectUser', 'user_id');
}
}
The ProjectUser class:
class ProjectUser extends \Eloquent
{
protected $table = 'project_users';
public function project(){
$this->belongsTo('Project'`enter code here`, 'project_id');
}
public function user(){
$this->belongsTo('User', 'user_id');
}
}
Now, you can get the users of a project like so:
$projects = Project::with('projectUsers.user')->get();
When looping through these objects you can access the user like this:
#foreach($projects as $project)
#foreach($project->projectUsers as $projectUser)
{{ $projectUser->user->id }}
#endforeach
#endforeach
