Ver 2.5-M1 User.scala: not found: value salt

[Kevin Lau]

Hi,

Ver 2.4 is good. 

Problem occurred "User.scala:218: not found: value salt [error]  salt.is/salt.get" when upgrade to Upgrade to Ver 2.5-M1.

Revert back to 2.4, is fine again.

Not sure if it is database related issue.

Thanks,

K.

Is this User.scala in your code base? If so, we probably need to see it. Look into posting example code at https://www.assembla.com/spaces/liftweb/wiki/Posting_example_code .

Thanks,

I use committer Peter P's sample code. 

https://github.com/karma4u101/Basic-SquerylRecord-User-Setup.

The only segment of code that surface the "salt" is as follow:

trait MyPasswordTypedField[OwnerType <: Record[OwnerType]] extends Field[String, OwnerType] with PasswordTypedField

{

def mySalt = 

{

val myValue = valueBox.map(v => v.toString) openOr ""

if(myValue.isEmpty || myValue.length <= 28)

 salt.get

else

myValue.substring(28)

}

...

Hi Lau

I will take a look at it. This code was published when there was a salt:ing discussion going on regarding record.
I have not done much work in lift involving record and user authentication lately but I think there may be some newer and better ways to handle it in lift 2.5 maybe David W can elaborate on that.

For reference here is the code:

I just took a quick look at the code and the reason it dose not compile for lift 2.5-M1 is that there are no longer a concrete value member 'salt' in the net.liftweb.record.field.PasswordTypedField trait and I am not sure how to get around this.
There is probably some new slicker mechanism for retrieving/holding the salt  in lift 2.5 record

... maybe someone already have a blog post or something showing how it should be done in 2.5 ?

Resolved: 
After taking a close look at this I found out that the password filed is salted by default (in 2.5) so you do not need to extend it with your own trait :)

so in class User modify the password field like this:
    :
    val password = new PasswordField(this) //with MyPasswordTypedField[User]
    :
i.e remove the trait extension.

I will do a initial clean up of the example code in a moment and get back to it later to get rid of more dead code.

... my conclusion that the password field is salted by default may be a bit hasty (still using hashpw with BCrypt for that)
... anyway you do not need to override the match_? function and other stuff in PasswordTypedField anymore to have a salted password.

The Basic-SquerylRecord-User-Setup example [1] is now updated to work with Lift 2.5-M1
