I have one class with some constant value like below :

```
class MyClass
{
    const ACCESS_NONE = 0;

    const ACCESS_SUBMIT = 1;

    const ACCESS_VIEW = 2;

    const ACCESS_APPROVE = 3;
}

```

How can I create something like below in my twig file with Symfony2 :

```
        <select name="someName">
            <option value="ACCESS_NONE">None</option>
            <option value="ACCESS_VIEW">View</option>
            <option value="ACCESS_SUBMIT">Submit</option>
            <option value="ACCESS_APPROVE">Approve</option>
        </select>

```
