Merry X’mas first
I have “Product”,“Category”,“Subcategory” 3 Model, and when new
“Product”, I want to use “Dynamic Select Menus” just like Ryan
mentioned in http://railscasts.com/episodes/88-dynamic-select-menus
I have everything down. But when I visit the js file, I got following
You have a nil object when you didn’t expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.each
Extracted source (around line #3):
2: var subcategories = new Array();
3: <% for subcategory in @subcategories -%>
4: categories.push(new Array(<%= category.id %>, ‘<%=h
subcategory.subcategory_name %>’, <%= subcategory.id %>));
5: <% end -%>
Anyone got an idea, how does it happen?
