i'm getting error:

the provided regular expression using multiline anchors (^ or $).  did mean use \a , \z, or forgot add :multiline => true option?  

when loading 1 page in rails application.

it highlights model it's using saying error is:

class associate < locations::associate 

this model:

class associate < locations::associate   # returns array of permissions valid @ associate level.  #  def self.associate_permissions   associate_permissions  end   # generates array of permission values can used in new or edit  # template.  #  def permission_list    my_permissions = (permissions || '').split(/,/)    list = []    associate.associate_permissions.each |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 |format|       format.html # index.html.erb       format.json { render json: @associates }    end  end  end 

can tell me how solve error?

i assuming getting error while rendering index view.

update 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
