NoMethodError in XXXXXXXXXController#create

Rails
#1

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 ?

hi,

could you tell me the line you got error ?

it sounds like u r going a add a HamtranZeeldegchs row.

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

in create action.
include the line p params in the beginnig and debug the params that
are coming to this create action

and you can save it hzs.personal_information_id = specific param

If this line is what’s causing the error, then it means that
params[:hamtran_zeeldegch] is nil.
So calling params[:hamtran_zeeldegch][‘0’] would cause the error.

class HamtranZeeldegchs < ActiveRecord::Base

Have a look at the Rails Guide on debugging. 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.
