How to join two names to create one function name

In my template I'm trying to dynamically define the path helper inside:

<%= link "Edit", to: @options[:resource]_path(@options[:conn], :edit, @options[:resource]) %>

So, I would like to use @options[:resource] to prepend the resource name and create the correct path helper, like: post_path(@conn, :edit, post)

As this is a function name and not a string all methods I've tried (#{}, <>, ++) don't work.

Since you want to dynamically call the function, Kernel#apply/3 should help here:

<%= link "Edit", to: apply(
       __MODULE__,
       :"#{@options[:resource]}_path",
       [@options[:conn], :edit, @options[:resource]]
    ) %>
