Hi all,

I am trying to create a mobile version of my application and for example  
for the mobile forums in routes.rb is:

map.resources :forums,  
:controller =\> ‘mobile/forums’,  
:path\_prefix =\> ‘/mobile’,  
:name\_prefix =\> ‘mobile\_’ do |forums|  
forums.resources :topics,  
:controller =\> ‘mobile/topics’,  
:name\_prefix =\> ‘mobile\_’ do |topics|  
topics.resources :posts,  
:controller =\> ‘mobile/posts’,  
:name\_prefix =\> ‘mobile\_’  
end  
end

In the topics index, to post a topic:

\<% if is\_logged\_in? -%\> \<%= link\_to 'Post New Topic', mobile\_new\_forum\_topic\_path(:forum\_id =\> @forum) -%\> \<% else -%\> \<%= link\_to 'Login to post a new topic', login\_url -%\> \<% end -%\>

The problem is the path mobile\_new\_forum\_topic\_path. I am getting an  
‘undefined method’ error. I know this is because the path is not right  
but I have tried all various combinations e.g. mobile\_new\_topic\_path,  
forum\_mobile\_new\_topic\_path etc but get the same error.

Anyone any ideas?

Thanks

Steve

I got it sorted out. It turned out to be new\_mobile\_topic\_path. So  
obvious its frightening :@o

Thanks
