Question

We have this string: “according to posts #4,#5 and #6 the word…”

I want to convert the “#4”, “#5” and the “#6” to links, using the link_to helper (the numbers are ids of a Model)

How can I do this? Is this difficult? Thank you in advance.

Answer 1

Good candidate for a helper method:

def link_ids(string)
  string.gsub(/#(\d+)/) do
    link_to "##{$1}", mymodel_path($1)
  end
end
