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:
if @personal_information.save
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
hzs.save
MODEL:
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 ?
-------------
Thanks
Tsolmon

There you will find methods for debugging your code. In particular you could use ruby-debug to break into your code before that line and check that the data are ok.
