如何让 friendly_id gem 开始使用 Rails 5.0.0.rc1？

Question

我在 rails 应用程序中使用 friendly_id。我在 gemfile 中有以下内容。

gem 'friendly_id', '~> 5.1'

每当我访问用户个人资料时，我都会收到 404 错误。

用户控制器，显示方法

  def show
    @user = User.find(params[:id])
    @microposts = @user.microposts.paginate(page: params[:page])
    respond_to do |format|
      format.html
      format.js    
    end      
  end

User.rb

  extend FriendlyId
  friendly_id :name, use: [:slugged, :finders]

我认为 friendly_id 不起作用。
知道如何解决这个问题吗？谢谢

Answer 1

我相信您要做的是用户 Model.friendly.find 而不是 find。

def show
  @user = User.friendly.find(params[:id])
  @microposts = @user.microposts.paginate(page: params[:page])
  respond_to do |format|
    format.html
    format.js    
  end      
end

我希望您已经使用 FriendlyId 扩展了您的模型。让我知道它是否有效。

Answer 2

当您想使用...

extend FriendlyId
friendly_id :name, use: [:slugged, :finders]

...你需要安装master分支(friendly_id 5.2.0.beta.1)

gem 'friendly_id', github: 'norman/friendly_id'

如果这样做，则不必更换控制器(Model.friendly.find)

Answer 3

更新到5.2.1解决。

gem 'friendly_id', '~> 5.2.1'
