提供的正则表达式使用多行锚（^ 或 $）？ [复制]

Question

我收到一个错误：

The provided regular expression is using multiline anchors (^ or $).  Did you mean to use \A and \z, or forgot to add the :multiline => true option? 

在我的 Rails 应用程序中仅加载一页时。

它突出显示它正在使用的模型，说错误是：

class Associate < Locations::Associate

这是模型：

class Associate < Locations::Associate

 # Returns an array of permissions which are valid at the associate level.
 #
 def self.associate_permissions
  ASSOCIATE_PERMISSIONS
 end

 # Generates an array of permission values that can be used in the new or edit
 # template.
 #
 def permission_list
   my_permissions = (permissions || '').split(/,/)
   list = []
   Associate.associate_permissions.each do |value|
     list << {:label => value[0], :value => value[1], :checked => my_permissions.include?    (value[1])}
   end
   list
 end

end

控制器：

class AssociatesController < ApplicationController
  def index
    @associates = Associate.paginate :order => 'code',
                                     :page => params[:page], :per_page => 50
    respond_to do |format|
      format.html # index.html.erb
      format.json { render json: @associates }
   end
 end

end

谁能告诉我如何解决这个错误？

Answer 1

我假设您在渲染索引视图时遇到了错误。

使用

更新index操作

@associates = Associate.order('code').paginate(:page => params[:page], :per_page => 50)

而不是

@associates = Associate.paginate :order => 'code',
                                     :page => params[:page], :per_page => 50

Answer 2

我发现了我的问题。我有一个可以运行我大部分模型的 gem。在我拥有的 gems 模型中：

class Locations::Associate < Locations::Database
  require 'digest'

  attr_accessible :code, :email, :include_on_reports, :name,
                  :permissions, :phone, :writer

  has_many :associate_branches, :dependent => :destroy

  validates :code, :presence => true, :uniqueness => true,
                   :format => { with: /^[A-Z]{3}\d{4}$/, on: :create }

.....
end

我不得不将正则表达式更改为：

validates :code, :presence => true, :uniqueness => true,
                   :format => { with: /\A[A-Z]{3}\d{4}\z/, on: :create }

感谢所有帮助。
