Hi, there must be something wrong somewhere in my unit test because  
there’s a model I can’t have any callback executed on.

In my unit test I do  
@image = Image.new  
@image.set\_uploaded\_file({:file =\>  
uploaded\_file(“pic1.jpg”,“image/jpeg”,“article-picture.jpg”),  
:article\_id =\> @article.id,  
:title =\> ‘Titre test’  
})  
breakpoint  
assert @image.save

When breakpointing, and trying @image.save manually I get a “true” as a  
result. So I presume everything went fine.

The model is :  
class Image \< ActiveRecord::Base  
belongs\_to :article  
before\_destroy :on\_before\_destroy  
after\_save :on\_after\_save  
validates\_presence\_of :extension

#cutted code

def on\_after\_save  
breakpoint  
end

end

The breakpoint in on\_after\_save is never reached.

I’m pulling my hairs out since yesterday - Any idea ?

Thanks

I think you just do it like this:

class Image \< ActiveRecord::Base  
belongs\_to :article  
validates\_presence\_of :extension

#cutted code

def after\_save  
breakpoint  
end

end
