Getting exact error type in from DbValidationException

Question

I have the situation where I\'m initializing my model in DatabaseInitializer() for EF 4.1 and get this annoying error \"Validation failed for one or more entities. See

Answer 1

The best solution in my opinion, is to handle this kind of errors in a centralized way.

just add this method to the main DbContext class :

public override int SaveChanges()
{
    try
    {
        return base.SaveChanges();
    }
    catch (DbEntityValidationException ex)
    {
        string errorMessages = string.Join("; ", ex.EntityValidationErrors.SelectMany(x => x.ValidationErrors).Select(x => x.PropertyName + ": " + x.ErrorMessage));
        throw new DbEntityValidationException(errorMessages);
    }
}

This will overwrite your context's SaveChanges() method and you'll get a comma separated list containing all the entity validation errors.

hope this is helpful.
