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: git_access_project.rb
    path of file: ./repos/gitlabhq/lib/gitlab
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Gitlab
  class GitAccessProject <
    
    def ensure_project_on_push!
      return if project || deploy_key?
      return unless receive_pack? && changes == ANY && authentication_abilities.include?(:push_code)
      return unless user&.can?(:create_projects, namespace)

      project_params = {
        path: project_path,
        namespace_id: namespace.id,
        visibility_level: Gitlab::VisibilityLevel::PRIVATE
      }

      project = Projects::CreateService.new(user, project_params).execute

      unless project.saved?
        raise CreationError, "Could not create project: #{project.errors.full_messages.join(', ')}"
      end
