Error while using Remote Property of DataAnnotation?

Question

I am having a problem using the remote property of the data-anotation.

I am having a model for user which stores the data:

[DataType(DataType.EmailAddress,ErrorMessage="please enter valid email")]
[DisplayName("Email Address")]
[Required(ErrorMessage = "Email is Required")]
[Remote("CheckUniqueEmail","User",ErrorMessage="An account with this email address already exists.")]
public string Email { get; set; }

and I am checking the distinct user email while creating the new one...

When I try to login with the email and password in the different controller, it still calls the Remote and checks for the unique email...

I think I have to exclude the email and password property in the Login controller - but I don't know how.

Answer 1

You can also use the MetadataType to reuse the same base model and apply different validations. Example Here.

Answer 2

You should use another model for logging in at LoginController.

These validations will be used everywhere you use this model.

Answer 3

you need to use 2 different view models, one for creating an account and one for logging in.
