ruby on rails – Display code block but also resolve variable within it

  • 0

[ad_1]

Rails 7 / Ruby 3

I’m currently working on a site that requires code examples to be displayed on a page – I can get these to display utilising the extra % character trick, however, for some of the examples I need to have a variable within them that is resolved (e.g. like the users’ own API key etc…).

Consider I have @variable = "Resolved Variable"

<%%= link_to @variable, variable_path %>

Outputs on the page explicitly as
<%= link_to @variable, variable_path %>

But I really need the @variable to resolve and show on the page as:

<%= link_to "Resolved Variable", variable_path %>

I’ve tried all kinds of escaping the variable, but it seems that <%%= ensures that nothing following it can be resolved.

Any ideas?
