On Page 98, the proposed changes to app.html.eex
include the following code:
<a href="http://phoenixframework.org/" class="phx-logo">
<img src="<%= Routes.static_url(@conn, "/images/phoenix.png") %>" alt="Phoenix Framework Logo"/>
</a>
However, the compiler is complaining about the syntax and suggests the following:
<a href="http://phoenixframework.org/" class="phx-logo">
<img src={ Routes.static_url(@conn, "/images/phoenix.png") }
alt="Phoenix Framework Logo"/>
</a>
So basically the <%=
element is not allowed within attribute values and braces should be used instead.
I guess this might be a change in how Phoenix Templates work added after the book was published?
