Hi
I am very new to RoR and am learning using the Agile Web Development
with Rails referece. I am slowly creating the Depot application and
have a problem setting up an image to act as a hyper link.
The code snippt I specifically have a problem with is
<%= link_to image_tag(''<%= product.image_url %>''),
:action =>
:add_to_cart, :id => product %>
If I replace <%= product.image_url %> with static text e.g.
/images/17.jpg the line of code works but I need to change the image
for each db record.
I have spent hours searching the web to help point me in the right
direction to no avail.
Thanks in advance for your help
Mark

You don''t need to use the output tags (<%= %>) in that string. In fact, it shouldn''t be a string at all in this case. This should work fine: <%= link_to image_tag(product.image_url), :action => :add_to_cart, :id => product %> Hope that helps, Steve --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

What you have effectively done here is tried to firstly put a string literal into the image_tag method. The you''ve used an erb escape inside ruby script. The good news is you don''t need to do this :) I imagine that if you looked at your source you would find something like <a href="/add_to_cart/2"><img src="<%= product.image_url %>" /></a> Instead use <%= link_to image_tag( product.image_url ), :action => :add_to_cart, :id => product %> That should resolve the image url to the product objects image_url method. Hope that helps a bit. Cheers Dan --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Also, there is no need for such complex transformations. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
