Question

I have an asset_category table(columns 'asset_category_id', 'category') and an asset table(columns 'asset_id', 'asset_category_id') and want display the (columns 'asset_id', 'asset_category_id.category,') from the asset table instead of just the 'asset_id' n 'asset_category_id' columns.

return view('category', ['asset_categories' => $asset_categories]);
}
public function add(Request $request){
$this->validate($request, [
'asset_category_id' => '',
'category' => 'required'
]);
$asset_categories = new Asset_category;
$asset_categories ->asset_category_id = $request->input('asset_category_id');
$asset_categories ->category = $request->input('category');
$asset_categories ->save();

<tr>
<td>{{ $asset->asset_id}}</td>
<td>{{ $asset->category->category}}</td>
when i run the project i get a FatalErrorExeception which says
Class 'Asset_category' not found in HasRelationships.php

Answer 1

You have Asset_category in a namespace. Try changing this:
return $this->belongsTo('Asset_category');
to this:
return $this->belongsTo(Asset_category::class);

Answer 2

You must end #foreach with #endforeach
You must declare protected $table = 'table_name'; in model because in default laravel generate table name to plural form of model's class name
Try to return this:
return $this->belongsTo('Asset_category');
return $this->hasMany('Asset', 'asset_category_id');
to this:
return $this->belongsTo(Asset_category::class);
return $this->hasMany(Asset::class, 'asset_category_id');
