This is Ruby/AJAX form similar with some special parameters for OVF Template provisioning.

ManageIQ/manageiq#19718

Depends on ManageIQ/manageiq#20636

@lfu please review/test

would be nice if this complex if statement (used twice in this file) can be extracted out into a tiny method named so that a developer can better understand the intent. So, instead of
if params[:display] || params[:template_id] || params[:manager_id] || params[:ovf_template_id]
it would say something like
if automate_catalog_needed?

and that method would be defined as

def automate_catalog_needed?
  params[:display] || params[:template_id] || params[:manager_id] || params[:ovf_template_id]
end

is this comment still relevant?

@skateman New fields added on this form were: Resource Pool, EmsFolder, Host, OVF Template, VM Name, Accept All EULA.

The PR testing went well 👍

Code looks good, is it enough if I believe @lfu that it works? 😉

[lfu]

Testing went well.

@h-kataria the rubocop issues seem valid, you probably copied the indentation from a different level.

[lfu]

Tested again and LGTM 👍

@h-kataria if this is ready for a merge, can you please squash the commits?
