I have created a very simple model called Discussion and one of the columns is a boolean called resolved. The idea being that once a discussion item has been resolved that value is set to true.

On the edit form, I tried to put in some logic based on the value of that field.

```
<%= form_for(@discussion) do |d| %>
    ...
<% if d.resolved == "true" %>
    <p>The discussion is resolved</p>
<% else %>
    <p>The discussion is not resolved</p>
<% end %>
<% end %>

```

However, I'm getting an error message

```
undefined method `resolved' for #<ActionView::Helpers::FormBuilder:0x00000101674678>

```

I tried adding an attr\_accessor line to my model but that didn't do anything for me either. I'm not sure what I have to do to fix this. I'm pretty new to rails, so I'm sure that whatever the problem is it's probably pretty simple to fix, but I just don't get it. Thanks.
