Laravel 4.2 - Use where clause on related tables - laravel

Question

I am working with two models, UserType and User - UserType hasMany User.
I am trying to retrieve a list of Users associated with a UserType that has the property receive_email set to 1 (true).
I have tried:
$userGroups = UserType::with(['Users' => function($query) {
$query->whereReceiveEmail(1)->whereNotNull('email')->whereNull('status');
}])->whereIn('id', [10, 1])->get();
and the Where clause seems to be totally ignored. From the Laravel 4.2 docs -
$users = User::with(array('posts' => function($query)
{
$query->where('title', 'like', '%first%');
}))->get();
I have seen many people say that this is not the correct way to use eager loading constraints but I really do not know what that would be, they do not seem to do anything. So, the short question, how can I retrieve a listing of Users with receive_email set to 1 through the UserType relation?
UPDATE
Can someone explain to me what the example code from the docs above is supposed to do? I'm assuming that it is supposed to return Posts associated with Users that match the constraint of having a title LIKE "first." In my case, I'm trying to find Users associated with UserTypes where each User has receive_email set to 1. The only significant differences between my code and the example code is that I am applying whereIn() and the model names are different.
So, with the results from the example, would the following be true?
foreach ($users as $user) {
foreach ($user->posts as $post) {
// matching posts with titles LIKE "first"
}
}

If you're after a list of users, then I suggest you actually start with that model and make use of whereHas to filter by user type:
$users = User::where('receive_email', 1)
->whereNotNull('email')
->whereNull('status')
->whereHas('UserType', function($q){
$q->whereIn('id', [1, 10]);
})
->get();
And actually, since the user type id should exist as foreign key in the users table, you don't even need whereHas:
$users = User::where('receive_email', 1)
->whereNotNull('email')
->whereNull('status')
->whereIn('user_type_id', [1, 10]);
->get();
For RosterMember it's basically the same. Although now you have to use whereHas since it's a many-to-many relation:
$rosterMembers = RosterMember::where('receive_email', 1)
->whereNotNull('email')
->whereHas('UserType', function($q){
$q->whereIn('user_type_id', [1, 10]);
})
->get();

I'm not 100% familiar with relationships, they've always been a bit tricky. But from what I understand, you want all the Users in UserType 1 and 10 that have receive_emails set to 1. So, this should work:
$result =
UserType::whereIn("id", array(1, 10))
->first()
->users()
->where("receive_email", "=", 1)
->whereNotNull("emails")
->whereNull("status")
->get()
;
What this should do is return all the accessible fields from both id 1 and 10 of UserType as well as all fields from the User table. If you run a dd($result) on this query, you should see an entry for UserType id 1 connected to all the Users that have receive_email set to 1, and another set for UserType id 10.
I can't guarantee that this will work without seeing your UserType.php and User.php classes, as the relationships might not be set, but if you followed Laravel convention:
public function users(){
return $this->hasMany("User");
}
and the inverse
public function userType(){
return $this->belongsTo("UserType");
}
then it should work. Hope this helps! Also, I'm sure there are better ways to accomplish this, but this is what I came up with, and it seems to work on some of my existing projects with relationships.
Cheers!
