I'm aware of the other questions pertaining to this subject, but none seem to help. I want the paperclip image url passed to json so I can render it in a reactjs component. I obviously cannot use Rails' image_tag helper.
I've defined this method in my items model
def image_url
image.url(:thumb)
end
And this in my controller
def index
@items = Item.all
render :json => @items.to_json(:methods => [:image_url])
end
But literally all that does is replace the rendered page with json. How should I go about this? It doesn't make sense to create a migration and model validation specifically for the image url.
