I was just doing some development on my theme and I wanted to have custom messages on paid and members only posts. So I figured I would look up the documentation – and it turns out Ghost supports a #has function.
I tried to test the following code, but it did not work. The syntax is correct, else handlebars handily fails to load the page, but it does not have the desired effect.
I don’t think it’s possible for you to run your logic using just helpers - there is boolean member information but not boolean post visibility information
