Question

For all my form submissions, I am creating documents to take in the submitted information

e.g.
public static void formAction(@Valid FormDocument formDocument){
…
}

I like this as it keeps my controllers looking tidy and makes it easier to see what is being requested in a form.

My registration document looks (trimmed) like this:

@Email
@Required
public String email;
@Required
public String password;
@Required
public String confirmPassword;

My question is is there a way I can check that the password matches the confirmPassword field within this class itself. Currently I am checking in the controller and passing a validation message back in if it fails. I think it would be neater if it was done inside the document itself.

Thanks for any feedback/answers in advance!

Answer 1

From the Play documentation, they have your exact use case.

Equals

Checks that the value is equal to another parameter’s value, using the
value’s equals method, e.g. for checking for a password confirmation
field.

Annotation syntax:

@Equals("passwordConfirmation") String password

So, all you would need is

@Email
@Required
public String email;
@Equals("confirmPassword") 
public String password;
@Required
public String confirmPassword;
