Rails根据条件在HTML代码上包装link_to

Question

Is there a clean syntax to wrap link_to on html code based on condition? Because DRY, I don't want to repeat the same code.

<% if condition? %>
  <%= link_to bla_bla_path do %>
    <p>Some html here</p>
  <% end %>
<% else %>
  <p>Some html here</p>
<% end %>

I know there is link_to_if but it don't have the part else :(((

Answer 1

With link_to_if the block to pass is actually the else . Have a closer look at the documentation you linked to.

Anyway, using link_to_if won't solve your dryness issue either. What you want to do is using capture to assign the common html to a variable:

<% content = capture do %>
  <p>Some html here</p>
<% end %>

<% if condition? %>
  <%= link_to bla_bla_path do %>
    <%= content %>
  <% end %>
<% else %>
  <%= content %>
<% end %>
