Helper

Rails

How make a helper:

If value X is true: print

  • else
    • 2

    Try something like this:

    def current_li(content, x)
    klass = x ? “current” : nil
    content_tag(:li, content, :class => klass)
    end

    Thanks, but why this doesn’t work?

    <%= current_li {link_to “xxx”, :controller => “yyy”}, @x == 1 %>

    <%= current_li {link_to “xxx”, :controller => “yyy”}, @x == 1 %>

    because you’re passing a block that generates a link to . something
    like
    current_li link_to(…), @x == 1

    would probably work.

    I can’t make it work:

    def current_option(value, content, x)
    selec = x ? “selected” : nil
    content_tag(:option, content, :value => value, :selected => selec)
    end

    Come on, should be easy enough if you got the previous one :slight_smile: (not to
    mention that options_for_select etc. do this for you).
