ruby-on-rails - Rails dot instead of slash in URL

Question

In my routes.rb I have:

get "projects/:category_id" => "projects#index"

When I write projects_path(1) the generated URL is /projects.1 instead of /projects/1. Do you know why this is happening? Here is the output of rake routes:

 GET /projects/:category_id(.:format) projects#index

Answer 1

projects_path是索引，它只接受一个参数：格式。你要project_path(1)
