Tablebuilder customization

To answer your question correctly, I need to see the fields migration of your addon, and also the stream, which TB you want to display, migration. In general you could use the wrapper and the value props in a column definition. Also, you could use a Presenter class to display any data not storing in DB.

Lets say I have very simple table with only two datetime fields: start_date and due_date. As you can see in snippet, I want to add class "red" to due_date. But only if due_date is smaller than todays date. Can I use Carbon in Tablebuilder or something like this to compare date?

Also as you said i can use wrapper. But I want to add wrapper only if date has passed.

diff is not stored in database, it should be calculated every time i open table. So here i should use Presenter?
//fields migration
protected $fields = [
'start_date' => [
'type' => 'anomaly.field_type.datetime',
'config' => [
"mode" => "date",
]
],
'due_date' => [
'type' => 'anomaly.field_type.datetime',
'config' => [
"mode" => "date",
]
],
];

//stream
protected $assignments = [
'start_date',
'due_date',
];



//Tablebuilder colums
protected $columns = [
'start_date' => [
'sort_column' => 'start_date',
'wrapper' => '{value.start_date}',
'value' => [
'start_date' => 'entry.start_date',
]
],
'due_date' => [
'class' => 'red'
],
'diff' => [
'sort_column' => 'diff',
'wrapper' => '{value.diff}',
'value' => [
'start_date' => 'entry.start_date',
'due_date' => 'entry.due_date',
'diff' => '???',
]
],
];

Hello renaldas.

To do what you need you should do it in the presenter. You can create two methods like these into your stream presenter:

public function diff()
{
    $diff_date = $this->object->start_date->diffInDays($this->object->due_date); //dates in pyro are carbon objects like laravel
    return $diff_date;
}

public function dueDate()
{
    if($this->diff()>0)
    {
        return '<strong>'.$this->object->due_date.'</strong>';
    }    
    return $this->object->due_date;
}

In your table builder should put something like this:

 protected $columns = [
    'start_date',
    'entry.dueDate',
    'entry.diff'   
];

My fields and assigments are like yours:

    protected $fields = [
    'start_date' => [
        'type' => 'anomaly.field_type.datetime',
        'config' => [
            "mode" => "date",
        ]
    ],
    'due_date' => [
        'type' => 'anomaly.field_type.datetime',
        'config' => [
            "mode" => "date",
        ]
    ],
];

 protected $assignments = [
    'start_date',
    'due_date',
];

I have tried the code and it works perfectly.

I hope I've helped.
