Follow-up: Refactor controller to make code clearer and remove unused variables

As per @mwoolf's suggestion:

---

suggestion: There are two very similarly named objects being exposed to the view here @events and @table_events and it's not immediately clear what the difference between them is but both are used in the view, so must be necessary.

events: @table_events.to_json,
is_last_page: @events.last_page?.to_json

For readability, I would suggest naming the events that are passed to the Vue application events. The intention behind events: @events.json is very clear IMO.

Additionally, consider refactoring the controller so that is_last_page: @events.last_page?.to_json becomes is_last_page: @is_last_page.to_json or something similar.

events = Gitlab::Audit::Events::Preloader.preload!(
  AuditLogFinder
    .new(level: level, params: audit_logs_params)
    .execute
    .page(params[:page])
    .without_count
)
@is_last_page = events.last_page?
@events = AuditEventSerializer.new.represent(events)

You could then refactor the view:

events: @events.to_json,
is_last_page: @is_last_page.to_json,

I make no guarantees about how well this will play with Vue, as there may be things I've missed but hopefully, the intent behind my comment is clear 😄

We should change the following locations:

• ee/app/controllers/admin/audit_logs_controller.rb:14
• ee/app/views/admin/audit_logs/index.html.haml:4
• ee/app/controllers/groups/audit_events_controller.rb:23
• ee/app/views/groups/audit_events/index.html.haml:7
• ee/app/controllers/projects/audit_events_controller.rb:23
• ee/app/views/projects/audit_events/index.html.haml:7
