I am getting the following error when trying to link to an  
auto-generated route:

—\>  
NoMethodError in Entities#index

Showing entities/index.html.erb where line #36 raised:

undefined method `edit\_entity\_client’ for #ActionView::Base:0x49ea3c8

Extracted source (around line #36):

33: \<%- if entity.client.nil? -%\>  
34: \<%= link\_to ‘Add Client Role’, new\_entity\_client(entity)  
-%\>  
35: \<%- else -%\>  
36: \<%= link\_to ‘Edit Client Role’,  
edit\_entity\_client(entity) -%\>  
37: \<%- end -%\>  
38:

Request

Parameters:

None

\<—

The routes.rb file contains this:  
…  
map.resources :entities do |entity|  
# An entity can only have one client role  
entity.resource :client  
entity.resources :locations  
# And only one vendor role  
entity.resource :vendor  
end  
…

and the link\_to targets, new\_entity\_client and edit\_entity\_client, both  
show up when I perform a rake routes:

# rake routes

…  
new\_entity\_client GET /entities/:entity\_id/client/new  
{:controller=\>“clients”, :action=\>“new”}  
formatted\_new\_entity\_client GET  
/entities/:entity\_id/client/new.:format  
{:controller=\>“clients”, :action=\>“new”}  
edit\_entity\_client GET /entities/:entity\_id/client/edit  
{:controller=\>“clients”, :action=\>“edit”}  
formatted\_edit\_entity\_client GET  
/entities/:entity\_id/client/edit.:format  
{:controller=\>“clients”, :action=\>“edit”}  
…

But I nonetheless get the error above. My question is why is the method  
edit\_entity\_client missing? What am I doing wrong?

I am leaving off the trailing \_path/\_url suffix, that is what. The  
correct method call is edit\_entity\_client\_path(entity)
