Why is there a wrong number of arguments error whe

问题:

In the Rails 4.1.1 version of an app, I have the following create method in articles_controller:

def create
  @article = Article.new(article_params)
  authorize @article
  if @article.save
    flash[:notice] = "Successfully created article."
    redirect_to edit_article_path(@article)
  else
    render :new
  end
end

However, after updating to Rails 4.2 the following error accounts when the redirect is attempted:

wrong number of arguments (2 for 1)

Why does this error occur and how can it be resolved?

回答1:

The issue was caused by the Gemfile containing an outdated version of Turbolinks (2.2.2). I resolved the issue by upgrading Turbolinks to version 2.5.3.

In Gemfile:

gem 'turbolinks', '~> 2.5.3'
