Laravel Eloquent Relationship Confusion - php

Question

Here is my situation;
I have an agreements table which will list the different types of agreements there are. It's a lookup table basically.
I have a client_agreements table which list which clients have signed up to which type of agreement. I have an agreement_id within this table (foreign key id).
As I am using Laravel, here is my Controller method to view all agreements for a specific client;
public function index($client_id)
{
$client_agreements = Agreement::find($client_id);
return View::make('client_agreements.index')
->with('client_agreements', $client_agreements);
}
Here is my Agreement Model;
class Agreement extends Eloquent {
protected $table = 'agreements';
public function client_agreements(){
return $this->hasMany('ClientAgreement', 'agreement_id');
}
}
So I want to output in the view from the agreements table;
agreement_type
level
and from the client_agreements table;
start_date
expire_date
My View code (which I'm sure is wrong but don't know why) is essentially;
#foreach($client_agreements as $client_agreement)
<tr>
<td>{{ $client_agreement->agreement_type }}</td>
<td>{{ $client_agreement->level }}</td>
<td>{{ $client_agreement->start_date }}</td>
<td>{{ $client_agreement->expire_date }}</td>
</tr>
#endforeach
What am I doing wrong?

You can do it like this:
$client = Client::with('agreements')->find($client_id);
$client_agreements = $client->agreements;
return View::make('client_agreements.index')
->with('client_agreements', $client_agreements);
And in your view:
#foreach($client_agreements as $client_agreement)
<tr>
<td>{{ $client_agreement->agreement_type }}</td>
<td>{{ $client_agreement->level }}</td>
<td>{{ $client_agreement->pivot->start_date }}</td>
<td>{{ $client_agreement->pivot->expire_date }}</td>
</tr>
#endforeach
This would require the following setup:
Client model
class Client extends Eloquent {
public function agreements(){
return $this->belongsToMany('Agreement', 'client_agreements')->withPivot('id', 'start_date', 'expire_date');
}
}
Agreement model
class Agreement extends Eloquent {
public function clients(){
return $this->belongsToMany('Client', 'client_agreements')->withPivot('id', 'start_date', 'expire_date');
}
}
