Hi Guys,
I am using attatchment_fu to adding images to my rails app, and have the following
<%= article_image_for(@article) %>
which displays the image for my article.. however i just want a text link to the image instead of the image itself...
can this be done with a link_to? or an <a href=@article.image ...??
i know this is probably a simple thing to do!! cheers..!!
Here is my code.................
Is it not as simple as changing the above to link_to 'click me', article_img
?

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

ummm interesting...
module Admin::ArticlesHelper def article_image_for(article) if article.article_image article_img = article.article_image.public_filename # link_to image_tag(article_img), article.article_image.public_filename
link_to 'click me', article_img, article.article_image.public_filename #else #image_tag("blank-image.png") end end end
this is my adapted articles helper method...
Well you are. Just link_to 'click me', article_img
is quite enough.

OK I understand now.
As a quick secondary question, I was wondering why when I have a button to delete the image from the database it works perfectly in the edit.html.erb file, but when I move the button into the _form.html.erb file so that it sits next to the other image related elements the @article_image.id value is not passed accross... in fact I dont think it even is picked up in the first place.
<%= button_to "Delete Image", { :action => "delete_article_image", :article_image_id => @article_image.id } %>
def delete_article_image @article_image = ArticleImage.find(params[:article_image_id]) @article_image.destroy
respond_to do |format| format.html { redirect_to(admin_articles_url) } format.xml { head :ok } end end
As is the code for the button works on the edit page (which holds the partial _form) but sits outside the rest of the elements and looks rediculous having a "delete image" button at the bottom of the page.
Probably because behind the scenes the button helper creates a form and you can't nest forms

Umm... don't use that helper? You can always construct the control yourself.

booger.... is there a potential workaround?
Several. Al's given you one. Here's two more..
1) Use your existing code, but separate structure from presentation. Fix the structure by putting the button (i.e., a form with no input fields) outside the form tags and use CSS to position it.
2) Modify your existing code to use link_to or a variation with images instead of text
