Clean validated data

[jede]

It would be great to use validate to clean the data a user sends in. Basically I want a way to whitelist attributes to make them optional. So for a user you should be able to pass in description, but not createdAt. Here is a example of how it could work:

data = 
  name: 'Test'
  description: 'Yaay'
  createdAt: 'omgomg'

constraints =
  name:
    presence: true
  description: true

validate.async(data, constraints).then (params) =>
  # params won't contain createdAt
  User.create(params)

Great idea.

My proposal is the following:

• validate.async passes the attributes to the resolve callback.
• validate.async cleans the data unless a new cleanAttributes is set to false
• validate.cleanAttributes will be added that accepts an object with the attributes to keep (will also accept constraints)

Sounds resonable?

Sounds amazing! 👍

There we go, though I'm not sure I think clean attributes should be on per default since it can break backward compatibility, what do you think @jede

[jede]

Not sure. If the output from async previously was not defined, then I think its ok!

[ansman]

@jede It passed the attributed before as well
