Rails - Oct 2007 - activerecord problem with contrains,belongs_to and has_many keyword

Hi,

I have two models:

AdvertisementImages (table: advertisement_images)
Advertisement (table: advertisements)

The table advertisement_images has a foreign key to advertisements
called advertisement_id. Both tables has one entry where the entry in
dvertisement_images belongs to advertisement.

The model code looks lik this so far:

class AdvertisementImages < ActiveRecord::Base
  file_column :image
  belongs_to :advertisement
end

class Advertisement < ActiveRecord::Base
  has_many :advertisementimage
  validates_presence_of :title, :body
end

Well... I want now have access to the advertisement images where ever
I display an advertisement.

for example:

I have a view where I can edit an advertisment. In this view I wanna
display the images as well.. My problem is, that the advertisement
doesn''t fetch the images automatically.

When I dump the advertisement via <%= debug @advertisement %>, my
output is :

--- &id001 !ruby/object:Advertisement
attributes:
  valid_to: "2007-10-06"
  body: some text
  title: Villa Katherina
  service:
  id: "1"
  valid_from: "2007-10-06"
  active: "0"
  parent:
errors: !ruby/object:ActiveRecord::Errors
  base: *id001
  errors: {}

I must have done a mistake somewhere in my declarations or so.... does
anyone know what I''ve done wrong ??

Thanx in advance,

alex !

Hi,

well I found my error.

I named the image model AdvertisementImages instead of AdvertisementImage.

Changing the name solved my problem.

Thanx for the guy in the irc channel for helping me out !


Bye, Alex
