ruby - Rails: Active Admin Association Image column -

i new ruby on rails , have installed active admin , trying customize

views.

i have product , image table. each image belongs 1 product.

now want display column associated image when showing products page.

at moment it´s image_url text isn´t working. later on do

have picture displayed in 50x50px.

how this? (image model: name:string image_url:text)

here have done :

activeadmin.register product  index     column "image" |image|         image.image_url     end     column :name     column :preview_text     column :full_text     column :price, :sortable => :price |product|       div :class => "price"           number_to_currency product.price      end     end  default_actions  end end 

i dont know how fix part " image. beginner in rails 2 days exp..

it seems syntax wrong , throwing error:

undefined method `image_url' #<product:0x00000101b5a458> 

thanks

you need image_url image object product.image.image_url.

regarding image size, can display image size want, so

column "image" |product|   image_tag product.image.image_url, class: 'my_image_size' end 

.css

.my_image_size {   width: 50px;   height: 50px; } 

or can resize image itself, gem such carrierwave.
