Question

在我的模型中，我有以下内容：

class Dyno < ActiveRecord::Base  
  include FriendlyId
  friendly_id :slug_candidates, :use => [:slugged, :history, :finders]

  def should_generate_new_friendly_id?
    car.present? && horsepower_changed?
  end

  def slug_candidates
    [
      [car.owner, :horsepower, "horsepower-dyno"],
      [car.owner, car.nickname, :horsepower, "horsepower-dyno"]
    ]
  end

当我尝试更新记录时：在生成一个slug之前，我运行我的验证并获得所有验证消息没有问题，但是一旦生成了slug，我点击save我得到404.即使我输入了所有正确的字段，然后点击保存将通过验证，它不保存记录并返回404

看起来它似乎试图通过新的“-slug-”查找并保存记录，然后记录中存在该slug。

在我的控制器中，我正在使用.friendly范围

def set_dyno
  @dyno = Dyno.friendly.find(params[:id])
end

此外，在我的控制器中，我在新操作中进行保存，以便我可以让用户从同一个新视图中添加相关图片。也许Friendly_Id可能会对现有记录中的nil slug做出反应？

def new
  @dyno = Dyno.new
  @dyno.save :validate => false   
end

我做错了什么？

我正在使用friendly_id 5.0.2

Answer 1

请从Dyno中删除友情。

friendly.find(params[:id])

因为你在这里使用finder

friendly_id :slug_candidates, :use => [:slugged, :history, :finders]

Friendly_Id 5.0 - ＆gt;记录不存在
