add custom validation message to IsDate, isAlpha, Is ,.....

[karimabdelhakim]

for example @IsDate(msg:"please enter a valid date")

@karimabdelhakim yeah, this would be useful and should be implemented. For now you can achieve this like so:

@Column({
  ...,
  validate: {
    isDate: {msg: 'your message'}
  }
})

Any PRs are welcome :) ;)

Some update about this feature?

[yocontra]

You can see this is implemented for some validators but not all of them: https://github.com/RobinBuschmann/sequelize-typescript/blob/master/src/validation/length.ts

You would basically just need to copy this to every validator in this folder, it wouldn't be a massive lift.
