Laravel Nova - concatenation of JSON properties from a field

[antlusher]

I have a JSON field called name with keys as follows: first, last, title.

On the index page, I wish to join all into one column - the full name.

At the moment I have this code, which does not work:

    Text::make('Name', function () { return $this->name->first.' '.$this->name->last; })

But this does work, which shows the title of the user:

    Text::make('Name', 'name->title')

Update:

I have the following in

app/User.php

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        'name' => 'json',
    ];

In Nova/User.php

    Text::make('Name', function () 
    { 
     return $this->name->first; 
    }),

Error:
Trying to get property 'first' of a non-object

The following returns an Object called Value and renders the 'title':

Text::make('Name', 'name->title')

The following returns an Object called Value and renders the the complete Object as a string:

Text::make('Name', 'name')

Value Object

Nova resources are not always resolved with an underlying Eloquent model instance. You need to check for the existence of $this->resource using the optional helper or similar.
