agged_with(params [:skill])ArgumentError:参数个数错误(给定2,预期为1)

Question

我在Rails 5 beta 3中遇到了gem acts-as-taggable-on的问题.

project.rb:

class Project < ActiveRecord::Base       
  acts_as_taggable
  acts_as_taggable_on :skills
end

的routes.rb

get 'tags/:skill', to: 'projects#index', as: :skill

projects_controller.rb:

class ProjectsController < ApplicationController
  def index
    if params[:category] && Category.exists?(params[:category])
      @category = Category.find(params[:category])
      @projects = @category.projects.order("projects.created_at DESC")    
    elsif params[:skill]
      @projects = Project.tagged_with(params[:skill])
    else  
      @projects = Project.all
    end

    @categories = Category.all
  end
end

在线@projects = Project.tagged_with(params[:skill])我得到以下错误:

ArgumentError:来自/usr/local/rvm/gems/ruby-2.3.0/gems/activerecord-5.0.0.beta3/lib/active_record/sanitization.rb:8:in的参数数量错误(给定2,预期为1) `的sanitize"

Answer 1

看起来像tagged_with在quote_value内部调用,这是一个alias_methodfor sanitize.

sanitize只需要一个参数,但是使用两个参数进行tagged_with调用quote_value,这会导致问题.

请参阅acts_as_taggable,ActiveRecord :: Sanitization以及引入此更改的 提交.
