Question

I have a nested form with the following field:

<%= f.label :size %><br />
<%= f.collection_select :size, Video::SIZE, :to_s, :to_s, :include_blank => true, :class => "sizefield" %>

As you can see, I’ve assigned the class, “sizefield”, to this field, but for some reason, my app is not recognizing it. What am I doing wrong here?

Rails functions that allow two terminal hashes get confused if you don’t specify the boundaries of those hashes exactly. For example:

collection_select(object, method, collection, value_method, text_method, options = {}, html_options = {})

You’re not separating the options from the html_options. Try this:

<%= f.collection_select :size, Video::SIZE, :to_s, :to_s, {:include_blank => true}, {:class => "sizefield"} %>
