You can use conditional checking inline, with "normal" 'if...else' blocks:
<% if @my_object.active? %>
This is active
<% else %>
You need to activate this one
<% else %>

or you can use the ternary operator:
<%= @my_object.active? ? "This is active" : "You need to activate
this one" %>

or you can use 'if' conditions as guards:
<%= "This is active" if @my_object.active? %>

.... it all depends what's best for your situation.
And if you find yourself doing the same checks in a couple of places,
extract that out to a helper method to keep your code DRY.

What have you tried? (what was the *exact* line of code) And what was
the result that was "to no avail"? (the *exact* response - did
something appear; nothing; or an error?)

Try the following resource as a primer; it should help you organise
your requests for help to be more likely to elucidate responses:
