Set entity field default value using YML

Question

I need get default value in class file

private $example_field = 0;

When I use this

example_field:
    options:
        default: 0

I got default database value, but when I try to persist without setting "su" I got error (column 'su' cannot be null).

Anyway,

example_field:
    default: 0

Does nothing.

Answer 1

this work for me:

fields:
    my_field:
        options:
            default: 5

Answer 2

The correct definition for a 0 default value would be by using quotes:

example_field:
    options:
        default: '0'
