Question

I am having trouble getting a two part argument to a link_to method to work, one of which is a Ruby method, and the other a params.

When I use the following code:

<%= link_to "Sort by most active", school_course_path(current_school, :params => "by_most_active") %>

I get the error that “can’t convert String into Hash”. I have tried to follow this question in terms of syntax for params, but can’t figure out why my :params is getting the error.

Thanks.

Edit:

To provide additional context, I have the following nested routes set up:

  resources :schools do
    resources :courses 
  end

You are using school_course_path which expects a school and a course as its first 2 arguments. You need to provide it with a course after passing current_school. You should
also change the params part with a different name like order. So your link_to should look something like

school_course_path(current_school, course, order: 'by_most_active')

If you are trying to get the most active courses for current_school, you should use school_courses_path

school_courses_path(current_school, order: 'by_most_active')
