VIEW
this is my select form
<div class="col-md-9">
<select name="clientId" id="clientId" class="form-control" placeholder="Select Client">
#foreach ($clients as $client)
<option value='{{$client->cn_id}}'>{{$client->cv_name}}</option>;
#endforeach
</select>
</div>
This is how i called the function to display it in my view
#foreach($projects as $project)
<tr class="odd gradeX">
<td>{{$project->cv_id}}</td>
<td>{{$project->cv_name}}</td>
<td>{{$project->client->cv_name}}</td><!--This is what cause an -->
<td>{{$project->cn_invoice_method}}</td>
<td>{{$project->cn_project_rate}}</td>
<td>{{$project->cn_note}}</td>
<td>
<a class="btn btn-success" title="edit" data-id={{$project->cv_id}} data-action="project-edit"><i class="fa fa-pencil"></i></a>
<a class="btn btn-danger" title="delete" data-id={{$project->cv_id}} data-action="project-delete"><i class="fa fa-times"></i></a>
</td>
</tr>
#endforeach
im still new to laravel, and what did i do wrong that make such an error like that?

Answer 1

I found the answer, i got the reference from here so based on that reference and the basic of x->y->z, we got to check first that x->y have some value in it if yes we got to check whether it's an object or just an array, in my case it was an array so rather doing something like this
{{$project->client->cv_name}}
which is that how to display an object, we should do something like this
{{$project->client['cv_name']}}
and that is how you solve your problem, cheers :D
