Question

I have a object menu item made available by controller to the corresponding view template. This object has two fields: label and link.

I initiated this object like following in the controller:

// first param is for label and second for link.
menuitem = MenuItem.new("Hello","Say_hello_path") 

In the view template I am typing this:

<%= link_to menuitem.label, menuitem.link %>

I expect this to result in: <a href="/say/hello">Hello</a>

but I am getting: <a href="Say_hello_path">Hello</a>

What am I doing wrong? Is there a better way to achieve the expected result?

Answer 1

The second item in MenuItem.new(“Hello”,”Say_hello_path”) is a string. When you call <%= link_to menuitem.label, menuitem.link %>, it is just putting the string.

You can try the following

// first param is for label and second for link.
@menuitem = MenuItem.new("Hello", say_hello_path) 

Or, you can try to eval the string in the link_to (you’ll need to fix the case on the method name).

<%= link_to @menuitem.label, eval(@menuitem.link) %> 

Eval isn’t usually recommended, but may be what you need in this case.
