I am doing the following:  
link\_to “delete my avatar”, user\_pictures\_path(:user\_id =\> @user, :id =\>  
@  
user.pictures.last), :method =\> :delete

and it is creating the following link:

[http://127.0.0.1:3000/users/4/pictures?id=10](http://127.0.0.1:3000/users/4/pictures?id=10)

Two things:

1. shouldn’t it create the following URL?  
[http://127.0.0.1:3000/users/4/pictures/10](http://127.0.0.1:3000/users/4/pictures/10)

i.e. not the ?id=10 but just /10?

1. Is there a cleaner way of building the url?

Thanks 🙂

If you are using nested routes like this:

map.resources :users do |user|  
user.resources :pictures  
end

Then you should be able to do this:

link\_to “delete my avatar”, user\_pictures\_path(@user,  
@user.pictures.last), :method =\> :delete

</div>

When I do that I get the following error:

undefined method `has\_key?’ for #Picture:0x266d170

when I do it my way I do not get an error but the id of the picture gets  
passed in querystring instead of URL… any suggestions peeps?

I think you want this instead

user\_picture\_path(@user, @user.pictures.last) \<== Note: singular form  
of ‘picture’ in the method name.
