Simple models

Simple models are used to store unique data and differ from regular models in the following ways:

1. The model class is inherited from the ModelSimple class.
2. The model SQL table contains only 2 fields, key and value, where key is a string primary key and value is a text field.
3. When creating a model, it is not necessary to enter key values ​​into the table, MV does this automatically.

Otherwise, the creation of a simple model follows the principles described in the section General principles of models and is configured in the same way as described in the section Configuring a model.

class Options extends ModelSimple
{
    protected $name = 'Settings';
    
    protected $model_elements = [
        ['Show banner', 'enum', 'promo', ['empty_value' => 'Always',
                                          'values_list' => [
                                              'morning' => 'In the morning',
                                              'evening' => 'In the evening',
                                              'night' => 'At night'
                                           ]]],        
        ['Date of accepting applications', 'date_time', 'work_date'],
        ['Price list', 'file', 'price_file'],
        ['Image at the top', 'image', 'top_image'],
        ['Image gallery', 'multi_images', 'gallery']
    ];
}

To run the simple model, as with a regular model, you need to:

1. Create a class with dataype fields.
2. Add the model class name to the config/models.php file.
3. Run migration from console or admin panel.

The process of extracting data from simple models into templates is described in the section Outputting data in a template.
