You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: compute_view_stat.rb
    path of file: ./repos/powerstation/powerstation/IDE_plugin/out/production/resources/static-analyzer/controller_model_analysis
    
    the code of the file until where you have to start completion: def compute_view_stat
	@view_not_in_closure = 0
	@view_in_closure_by_db_not_scale = 0
	@view_in_closure_by_db_scale = 0
	@view_in_closure_not_by_db = 0
	$node_list.each do |n|
		if n.getInstr.is_a?Call_instr and n.getInstr.getFuncname == "ruby_code_from_view"
			if n.getNonViewClosureStack.length > 0
				by_db = false
				by_db_scale = false
				n.getNonViewClosureStack.each do |cl|
					r = traceback_data_dep(cl, true)
					if r
						by_db = true
						by_db_scale = true unless r.card_limited
					end
