I'm glad to hear you're finding Backpack Pro and DevTools helpful! Let's address your question about managing relationships between devices and people. For your many-to-many relationship between devices and people with a pivot table (user_devices), you'll need to set up a few things to show the latest assigned person on your devices list. Setting up the relationshipFirst, make sure your models are properly set up with the relationship:
public function users()
{
return $this->belongsToMany(\App\Models\User::class, 'user_devices')
->withPivot('created_at')
->withTimestamps();
}
public function latestUser()
{
return $this->belongsToMany(\App\Models\User::class, 'user_devices')
->withPivot('created_at')
->withTimestamps()
->orderByPivot('created_at', 'desc')
->limit(1);
}
CRUD::column([
'name' => 'latestUser',
'type' => 'relationship',
'label' => 'Latest User',
'entity' => 'latestUser',
'attribute' => 'name', // or whatever attribute you want to display
]);Managing the relationshipFor editing the relationship, you can use the CRUD::field([
'name' => 'users',
'type' => 'relationship',
'label' => 'Users',
'entity' => 'users',
'attribute' => 'name',
'pivot' => true,
]);If you need to save additional data to the pivot table, you can use subfields as described in the CRUD Fields documentation: CRUD::field([
'name' => 'users',
'type' => 'relationship',
'label' => 'Users',
'entity' => 'users',
'attribute' => 'name',
'pivot' => true,
'subfields' => [
[
'name' => 'created_at',
'type' => 'datetime',
'wrapper' => ['class' => 'form-group col-md-6'],
],
// Add other pivot fields if needed
],
]);Additional ResourcesFor more detailed guidance on relationships in Backpack:

Just purchased Backpack Pro and DevTools and I am super amazed at how it was able to do something that took me two weeks in about 5 min. But I am struggling understanding a few things... Specially because the documentation is different than what I thought was a default install that would allow me to follow along with the video tutorial. my biggest hurdle is understanding the relationship part. I want to manage many devices for many people so I have a 3rd table called user_devices and the user id and the device_id .. on my devices controller, I would like to call the latest assigned person to the device and show that on my list.. but I am not sure how to do that. Anyway can point me to instructions on how to do that?
