将包装的锚点标记HTML转换为link_to

Question

I'm messing around with Bootstrap. There's some HTML code which is wrapped by an anchor tag. I'm not really sure how to convert it to the Rails link_to method. I looked at the Ruby on Rails documentation for link_to but I still cannot figure it out.

Here's the code:

<a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown <b class="caret"></b></a>

I tried the following but it's incorrect:

<% link_to("Users", users_path, { data: { toggle: "dropdown" }, class: "dropdown-toggle"} ) do %>
  <b class="caret"></b>
<% end %>

Answer 1

If the href is a pure '#" but no variables at all, it's better to copy the code directly from Bootstrap than making a link_to .

If you want to add variable/method say user_path , with this complex anchor, it's better to use the block argument of link_to . Move the first argument which is usually the anchor to the block.

<%= link_to users_path, data: {toggle: "dropdown"}, class: "dropdown-toggle" do %>
  <b class="caret"></b>
<% end %>
