needsReHash | Unprecise or wrong Docs

[ulri-one]

Hi community,

I have just a quick question based on needsReHash documentation found at
https://docs.adonisjs.com/guides/security/hashing#needsrehash

In the sample code section it says

if (Hash.needsReHash(user.password)) {
  // You will have to tweak the model hook to not
  // rehash the already hashed password
  user.password = await Hash.make(plainPassword)
}

Does the hint with model hook adaption make any sense for you?

Why not just write

if (//needsReHash) {
  user.password = plainPassword
}

Then the hook can do it's job and the hash is re-generated after the newest standards with the new work factor...

Or am I wrong and mis-understand something?

Kind regards
Robin
