The best way to do this is to have your method return the string and use <%= ... %>
as in fotanus’ answer, but in Rails if you really need to write output directly from a helper you could use the concat
method:
The preferred method of outputting text in your views is to use the <%= “text” %> eRuby syntax. The regular puts and print methods do not operate as expected in an eRuby code block. If you absolutely must output text within a non-output code block (i.e., <% %>), you can use the concat method.
So you can define a helper like this:
def my_method
if some_condition
concat "Something or other"
else
concat "Something else"
end
end
And then use it in a non-output block:
<% my_method %>
