Question

我在rails应用中使用了friendly_id。我在gemfile中有以下内容。

gem 'friendly_id', '~> 5.1'

每次访问用户个人资料时都会收到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不起作用不知道怎么解决这个问题？感谢

Answer 1

当你想要使用时......

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

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

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

如果这样做，则无需更改控制器（Model.friendly.find）

Answer 2

更新到5.2.1解决它。

gem 'friendly_id', '~> 5.2.1'

Answer 3

我相信你要做的就是用户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

我希望您使用FriendlyId扩展了模型。如果有效，请告诉我。

如何让friendly_id gem使用Rails 5.0.0.rc1？
