Re: [Rails] frozen? is defined by ActiveRecord

Ruby on Rails Friday, August 30, 2013

I have to connect to an existing database.
But i got 
ActiveRecord::DangerousAttributeError   frozen? is defined by ActiveRecord

  My code is here:
class Customer < ActiveRecord::Base
  establish_connection :my_connection
  self.table_name = 'customer'
    self.primary_key = 'customer_no'
  def self.get_all_customer
	@customer_data = Customer.find_by_sql("select customer_no from customer_table")
  	 return @customer_data
  end
end

Thanks

We are not telepathic so without knowing what you are doing it is
impossible to say.  Post the full error and stack trace  (if any) and
the section of code causing the problem.  Not your whole app just a
few lines around the area where the problem occurs.
