Question

Im trying to make 1 global function to display carrier wave images in different sizes. the problem is passing the size var in method call to the carrierwave helper like below:

def get_avatar(id, size)

@profile = User.find(id).profile rescue nil
  image_tag @profile.photos.first.file_url(:img_120x145)
rescue
  image_tag ("/assets/avatars/img_#{size}.png")

end

I tried all kinds of things but are unable to pass the size var to the @profile.photos.first_url(size here).

How should one approach this?

Answer 1

Heres what worked for me recently.

<% image_tag @profile.photos.first.url(size) %>
