Question

I am having trouble with some Ruby on Rails code. I have a data structure of nested resources (List has_many Tasks and a Task belongs_to a List). On my List.show page, I have the following line of code:

<td><%= link_to 'Show Task', list_tasks_path(@list, task) %></td>

The idea is that this page will link to a “show” page where I can view the details of an individual Task. I want the url to basically be

/lists/:list_id/tasks/:task_id

The problem is that the above code is directing me to

/lists/:list_id/tasks.task_id

on the index page of Task. How can I tell Rails to send me to the show page instead?

I have tried adding :action => show and :controller => tasks, as well as using show_list_tasks_path(@list, task). I also know that the structure itself is there because my show page works fine if I manually enter /lists/:list_id/tasks/:task_id.

Any help is appreciated. Thank you!

The problem here is that you’re using list_tasks_path when you should be using list_task_path.

The list_tasks_path method will generate a URL to the index action, as you know already, and will make the second argument be the format for this request.
