Hi all, I am new to ruby and as such really new to rails, I was  
wondering if anyone could help me out or point me in the right  
direction. I am wanting to know the proper way to link many pictures  
to a model “house”. That way if I look up my house, I will see all the  
pictures that are associated with it. Any help would be greatly  
appreciated.  
Thanks  
-J

Something like this will work:

class House \< ActiveRecord::Base  
has\_many :photos  
end

class Photos  
has\_attachment :content\_type =\> :image,  
:storage =\> :file\_system,  
:max\_size =\> 500.kilobytes,  
:resize\_to =\> ‘320x200\>’,  
:thumbnails =\> { :thumb =\> ‘100x100\>’ }

validates\_as\_attachment  
end

you will need the attachment\_fu plugin. A good tutorial on it here:

Once it is saved, how then do I display the picture, since it is not  
in the model…per se?
