Question

How can I prevent the image tag that calls the associated image from displaying if no image is associated with the record?

<%= image_tag @agent.avatar.url %> 

…gives me the text ‘Missing’ if there is no image associated with that agent. I want to test to see there is an image available first, then render the above tag if the test returns true.

Better yet, is there anyway for me to specify a default image if no image is specifically provided?

I use the following to find wether a model has an associated attachment:

<% if @agent.avatar.file? %>   <%= image_tag @agent.avatar.url(:normal) %> <% else %>   No attachment available! <% end %>
