Hello comrades ,
I got a error. I don’t understand that exception. What happened ?
You have a nil object when you didn't expect it! You might have expected an instance of ActiveRecord::Base. The error occurred while evaluating nil.
i written this code:
HamtranZeeldegchs.new(params[:hamtran_zeeldegch][‘0’]) # This line is may a error.
hzs = HamtranZeeldegchs.new(params[:hamtran_zeeldegch][‘0’])
hzs.personal_information_id = @[personal_information.id](http://personal_information.id) hzs.save
class PersonalInformation < ActiveRecord::Base
has_many :hamtran_zeeldegchs,:foreign_key => ‘personal_information_id’ , :class_name => ‘HamtranZeeldegchs’, :dependent => :destroy
class HamtranZeeldegchs < ActiveRecord::Base
belongs_to :personal_information , :class_name => ‘PersonalInformation’, :foreign_key => ‘:personal_information_id’
Can anyone help me ?
