Rails视图：有条件地显示文本和链接； 有没有比这更简单的方法？

Question

In a Rails (erb) view, I want to conditionaly display some text and a link.

Is there anything simpler than that:

<% if some_condition %>
        Go to  
<%=     link_to("Home", root_url) %>
<%  else %>
        See all
<%=     link_to("objects", my_objects_path) %>
<%  end %>

I am a bit annoyed by the number of <% and <%= tags.

Answer 1

As a helper (depending on actual usage, it could be an application-wide helper, a model helper, etc):

def home_or_objects c
  if c
    link_to "Go to home", root_url
  else
    link_to "See all objects", my_objects_path
  end
end

(I wouldn't linkinate only a single word--smaller target, and IMO less communicative. YMMV.)

Then in the view:

<%= home_or_objects some_condition %>

As a partial it's a matter of rendering the partial, perhaps passing the condition in as a local, or if it's an instance variable, it can be referenced directly without needing to be passed.

<%= render :partial => 'home_or_objects', :locals => { :c => some_condition } %>

(There are a few ways a partial could be handled. IMO a helper is more appropriate.)
