Distinguished if the user was created or if they already existed with a magic link

I would like to perform some actions once the user has been created via a Magic Link, for example sending a welcome email and initializing other resources in other domains. However, I don't see how to distinguish between creation and reading in an after_action. According to my tests, the values of the parameters are identical in both cases. Any ideas?

Solution:

Here is what works for me: ``` upsert_fields [:email, :last_signed_in_at] ...

Right now the only way is to compare the inserted at and updated at timestamps

Mhhh, when log in, the updated_at field does not seems to be updated

Ah, right you are 🤔 I mean, its hacky, but you could see if the user was "just created"

I added the "updated_at" field into the upsert_fields and it seems to work. upsert_fields [:email, :updated_at]

I think that means you're updating the user every time they sign in you may want to add a last_signed_in_at and set that in the sign in action

Indeed, that appears to be cleaner. I'll try that.

Here is what works for me:

upsert_fields [:email, :last_signed_in_at]

change set_attribute(:last_signed_in_at, &DateTime.utc_now/0)

attribute :last_signed_in_at, :utc_datetime_usec do
  allow_nil? false
  public? true
end

upsert_fields [:email, :last_signed_in_at]

change set_attribute(:last_signed_in_at, &DateTime.utc_now/0)

attribute :last_signed_in_at, :utc_datetime_usec do
  allow_nil? false
  public? true
end

In my case the only way of register is via magic link so the field can never be empty, at least at the moment. Thanks for helping me!
