Get data from Relation Tables

That is a pivot table, so you'll need to define the extra columns on that pivot table, and then can access them through the 'pivot' keyword.. See docs: https://laravel.com/docs/5.2/eloquent-relationships#many-to-many (scroll down to 'Retrieving Intermediate Table Columns' section)

@willvincent I think something is wrong here:

Property.php model

    public function property_characteristics()
    {
        return $this->hasMany('Proactiv\PropertyCharacteristic', 'property_id', 'id');
    }

DefaultCharacteristic.php mode

    public function default_characteristic()
    {
        return $this->belongsTo('Proactiv\DefaultCharacteristic', 'characteristic_id', 'id');
    }

Is this enough?

Or I need something like this:

    public function property_characteristics()
    {
        return $this->belongsToMany('Proactiv\DefaultCharacteristic', 'property_characteristics', 'property_id', 'characteristic_id');
    }

I solved with:

    public function characteristics()
    {
        return $this->belongsToMany('Proactiv\DefaultCharacteristic', 'property_characteristics', 'property_id', 'characteristic_id')
            ->withPivot('value');
    }

And method:

    public function getCharacteristic($name)
    {
        $value = $this->characteristics
                    ->where('name', $name)
                    ->first();
        if(!$value) return '?';
        return $value
            ->pivot
            ->value;
    }
