Embedded association with user ?

[ZePedroResende]

Hi, i need to create a profile that is a has_one association with the user.

This needs to be create in the register form (embedded) alongside the user.

Is there a standard way to do this in pow or do i need to override the controllers ?

Yeah, no need to override controllers. You just have to customize the changeset and add custom templates with the custom fields e.g. using Phoenix.HTML.Form.inputs_for/4.

If it should only update during registration then this might help you: #276 (comment)

@danschultzer thank you so much for the quick answer !
I already had changed the changeset and the template but i need to preload the profile assoc, so for what i understand for the other issue i probably need to do a custom context.

If it’s an embedded schema then you won’t have to preload it?

[danschultzer]

Oh reading your question again, I realize you probably didn’t mean embedded schema. So yes, you can use a custom context, but this should only be necessary for update of existing users.

@danschultzer im actually using the invitation extension with the register disable.
What would you recommend the custom context would look like with i only wanted to do the preload 😄 ?

[danschultzer]

This would work:

defmodule MyApp.Users do
  use Pow.Ecto.Context,
    repo: MyApp.Repo,
    user: MyApp.Users.User

  @impl true
  def get_by(clauses) do
    clauses
    |> pow_get_by()
    |> preload_profile()
  end
  
  defp preload_profile(nil), do: nil
  defp preload_profile(user) do
    MyApp.Repo.preload(user, :profile)
  end
end

But the above will preload the profile anywhere the get_by/1 is called. An alternatively would be to set up a custom invitation controller (with at least the show and update actions) to preload the profile. You would have full control over the flow that way, but it would be much more involved.

Here's an example of how you can override default controller actions with a custom controller for PowInvitation: #203 (comment)

I assume that the above worked. I'll close the issue.
