Planning out Eloquent relationships in Laravel 5 - laravel-5

Question

I have a Project model. Each Project can have a thumbnail, main image and other multiple assets / images (project details for example) and also multiple text contents (that would be placed in between these images). And each Project page will pull in these assets (except the thumbnail) and texts, and display them in a specific order (that I define by drag and drop on my control panel).
So basically the similar structure to what Behance uses for example. I'm trying to structure this using Eloquent and here is what I was thinking of doing:
I can have let's say Asset and Text models with hasMany() relationship on Project model. These two models would have a column called pageSort and then the controller would merge these two collections together and sort them using that pageSort column.
Any other suggestions?
EDIT:
I tried to use the polymorphic relationships in Laravel, but no success yet.
MyProject model:
public function nodes()
{
return $this->morphedByMany(Node::class, 'nodeable');
}
My Node model:
public function nodeable()
{
return $this->morphTo();
}
Then in my code I do the following:
$project = new App\Project;
$project->title = 'Some title';
$project->save();
$image = new App\Image;
$image->source = 'somefile.jpg';
$project->nodes()->save($image);
But I get the following error:
Illuminate\Database\QueryException with message 'SQLSTATE[42S22]: Column not found: 1054 Unknown column 'project_id' in 'field list' (SQL: insert into `nodeables` (`nodeable_id`, `nodeable_type`, `project_id`) values (5, App\Node, 1))'
So I guess it's trying to create an entry inside a pivot table nodeables. Then I created this table and it saved an entry inside the pivot table, but not inside nodes table.
This is driving me mad! :(

I would have a Node model that is polymorphic, and has your sort_order column. A Project would have many Node models, and a Node could be morphed to whatever you need: Text, Image, Video, and so on.
class Project extends Model
{
public function nodes()
{
return $this->hasMany(Node::class)->orderBy('sort_order');
}
}
class Node extends Model
{
public function nodeable()
{
return $this->morphTo('nodeable');
}
public function project()
{
return $this->belongsTo(Project::class);
}
}
// Example
class Text extends Model
{
public function node()
{
return $this->morphOne(Node::class);
}
}
