Does AutoMigration() also give NOT NULL attribute on database side?

Question content

In GORM, AutoMigration() also gives the NOT NULL attribute on the database side?

Thanks in advance

Correct answer

The answer is: No

So if you don't define not null (using the gorm field tag) to that specific field, gorm will not add the not null constraint to the field on the database side. Except for primary keys. By default, pk will be defined as a not null field.

How to define a field as not null in gorm:

type User struct {
    ...
    Email string `gorm:"not null"` // NOT NULL 
    ...
}

For more information, please refer to gorm official documentation: Field tags p>
