I’m attempting to create a tag that outputs a dollar value, such as

number\_to\_currency(tag.locals.item.price)

This isn’t working. What might I be doing wrong, or are there  
limitations to using rails helpers that I don’t understand?  
Thanks

I think you’ll just need to include the necessary helper in your tags  
module. I have some photos I am manipulating in tags logic, so I needed  
a  
helper. Simply:

include FileColumnHelper

And I had access to the helpers.

Thanks,

I assume you have read the extensions tutorial? It talks about creating  
tags:

Yup. But I don’t think the answer to my question about helpers is  
addressed there.
