Hi Guys,
I am using attatchment_fu to adding images to my rails app, and have
<%= article_image_for(@article ) %>
which displays the image for my article… however i just want a text
can this be done with a link_to? or an <a [email protected] …??
i know this is probably a simple thing to do!! cheers…!!
Here is my code…
articles_helper
def article_image_for(article)#else #image_tag (“blank-image.png”)
article_images table
id article_id size width height content_type
articles model
class Article < ActiveRecord::Base

looks like you’re passing that string to link_to twice.

ummm interesting…
module Admin::ArticlesHelper
link_to 'click me', article_img,
article.article_image.public_filename#else #image_tag (“blank-image.png”)
this is my adapted articles helper method…

<%= button_to “Delete Image”, { :action => “delete_article_image”,@article_image.id } %>

Use your existing code, but separate structure from presentation.
Modify your existing code to use link_to or a variation with images
