I didn’t know this earlier, but found a very good feature of GORM – ‘bypass’ constraints or ‘customize’ validation while saving a domain-object. I am not sure if there’s any name for this feature. But I am naming it as ‘bypass constraints’.<\/p>\n
[groovy]
\nif(domainObject.validate([‘field1’, ‘field2’])){
\n domainObject.save(validate:false, flush:true)
\n}
\n[\/groovy]<\/p>\n
Let’s discuss it with a use case. We create a user table with fields – id, name, email, password.
\nAnd email\/password are mandatory fields. <\/p>\n
[groovy]
\nClass User{
\n Long id
\n String name
\n String email
\n String password<\/p>\n
static constraints = {
\n name(nullable: true)
\n }
\n}
\n[\/groovy]<\/p>\n
Now there’s a requirement in the application – An existing user can invite a friend<\/strong>. With the help of ‘bypass constraints’ feature, it’s easier to handle this use-case without actually creating any separate domain to store invited users information. NOTE<\/strong>: To achieve this, you just need to set ‘password’ column as nullable true in your ‘user’ table. Above example\/use-case is just to explain ‘bypass constraints’ feature, nothing more than this. \ud83d\ude42 I hope it might help you somewhere.

\nFollowing code will create User entry with null password.
\n[groovy]
\nUser user = new User(name:userName, email:userEmail)
\nif(user.validate([’email’]) && user.save(validate:false, flush:true)){
