Setting values on new

[manuelmeurer]

I have models User and Message, and a user has many messages.
When I create a new message for a user, I would like to set the message's email field to the user's email.
How do I do that with Avo?

My first idea was to override the new action in the Avo::MessagesController and set the value there:

class Avo::MessagesController < Avo::ResourcesController
  def new
    super
    # How?
  end
end

Looking at the source for Avo::BaseController, I would need to access via_record, but I can't, probably because it's not an instance variable?
Or is there any easier way to do this that I missed?

Hi @manuelmeurer 👋

You're on the right track!

I'll open a PR to convert those variables into instance variables so they can be accessed externally when needed. In the meantime, I recommend replicating the internal logic used to retrieve the via_record in your own controller as a temporary workaround.

Let me know if you need help with that.

class Avo::CourseLinksController < Avo::ResourcesController
  def new
    super

    if is_associated_record?
      via_resource = Avo.resource_manager.get_resource_by_model_class(params[:via_relation_class])
      via_record = via_resource.find_record params[:via_record_id], params: params

      # Assign course_name from parent record (course)
      @record.course_name = via_record.name
    end
  end
end

Just created this issue to track the conversion from local to instance variables
