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
