Question

In my view file (*.html.erb), I would like to create a link that shows two model datapoints (name and vote count). In the case of Bobby, who has five votes, it would look graphically like:
Bobby(5).

How do I do this with a link_to, given that the string I want to show includes non-ruby parentheses?

Before turning it into a link, the code is,

<%= user.name %>(<%= link.user.reputation_value_for(:votes).to_i %>)

Thanks very much for your help!

Answer 1

Try this:

<%= link_to "#{user.name}(#{user.reputation_value_for(:votes).to_i})", whatever_path %>

When building a string with ruby code in it, just type it normally and put the ruby code you need in between this: #{}

When the page loads, the erb is compiled first and in my string above

#{user.name}

will be replaced with Bobby and

#{user.reputation_value_for(:votes).to_i}

will be replace with 8 (if that’s his reputation value) giving you

Bobby(8)
