rails link to nested route not working

Question

I have the following in routes:

resources :projects do
  resources :schedules
end

I am trying to go to the show schedule page. Rake routes lists this:

project_schedule GET  /projects/:project_id/schedules/:id(.:format)  schedules#show

I have the following link on another page to the schedules#show page:

<%= link_to 'Show Schedule', project_schedule_path(project.id, schedule.id) %>

The page returns the following error:

Couldn't find Schedule with id=26

Here are the params:

{"project_id"=>"26",
 "id"=>"48"}

I know a schedule exists with these id's because i can find it in the console:

<Schedule id: 48, project_id: 26, created_at: "2013-11-25 19:08:00", updated_at: "2013-11-25 19:08:00">

Why isn't the link working? Thanks.

Answer 1

Looks like you're trying to find the schedule using the project's id.

I'd do this in your controller:

# find the parent model first 
@project = Project.find params[:project_id]

# now get its associated schedule:
@schedule = @project.schedules.find params[:id]

You also might have the ids backwards in your link_to helper. You can try using the shortcut:

link_to 'Schedule', [project, schedule]

That gets converted to the project_schedule_path

Answer 2

Try

  <%= link_to 'Show Schedule', project_schedule_path(schedule.id, project.id) %>
