I'm getting an error:
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?
when loading only one page in my Rails application.
It highlights the model it's using saying the error is:
class Associate < Locations::Associate
This is the model:
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
The controller:
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
Can anyone tell me how to solve this error?

Answer 1

I am assuming that you are getting the error while rendering an index view.
Update the index action with
#associates = Associate.order('code').paginate(:page => params[:page], :per_page => 50)
instead of
#associates = Associate.paginate :order => 'code',
:page => params[:page], :per_page => 50

I figured out my issue. I have a gem that runs most of my models. in the gems model I have:
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
I had to change the regex to:
validates :code, :presence => true, :uniqueness => true,
:format => { with: /\A[A-Z]{3}\d{4}\z/, on: :create }
thanks for all the help.
