Auth with custom fields

[rafaelcascalho]

Hey guys!! Hope everyone is safe. 🙇

Context

I have a defined database that my client very much insists on using, and on his database, the uid field is not used for login and I also require a third field. I need web and api guards.

Question

How can I do that using the built-in auth? I mean, I'm thinking about using attempt(fields), but seems that it requires that the first field be a uid field, which in this case it's not. So, I'm wondering about the possibilities.

Simply fetch the user yourself from the database, verify the password and then use auth.login method. This is how it should roughly look like.

import Hash from '@ioc:Adonis/Core/Hash'

const user = await User.query().where().firstOrFail()
const isValid = await Hash.verify(user.password, passwordSubmittedInForm)

if (!isValid) {
  // return error
}

await auth.login(user)
