Hi,

in my app, using the error\_message\_on form helper like this:

User name:  
\<%= error\_message\_on ‘user’, :name %\>  
\<%= f.text\_field :name %\>

generates the following error:

undefined method `errors’ for :user:Symbol

I am using edge revision 5813 and the simply\_helpful plugin. Is there a  
way to fix this?

Ingo

I’m getting this on 5813 as well ☹

Hi,

The problem is in active\_record\_helper.rb, in the method  
error\_message\_on replace for the old code:

def error\_message\_on(object, method, prepend\_text = “”, append\_text =  
“”, css\_class = “formError”)  
#if object = instance\_variable\_get("@#{object}") && errors =  
object.errors.on(method)  
# content\_tag(“div”, “#{prepend\_text}#{errors.is\_a?(Array) ?  
errors.first : errors}#{append\_text}”, :class =\> css\_class)  
#else  
# ‘’  
#end  
if errors =  
instance\_variable\_get("@#{object}").errors.on(method)  
content\_tag(“div”, “#{prepend\_text}#{errors.is\_a?(Array) ?  
errors.first : errors}#{append\_text}”, :class =\> css\_class)  
else  
‘’  
end  
end
