Rails routing error: No route matches [POST] "/students/1" - ruby-on-rails

Question

I'm getting a routing error: No route matches [POST] "/students/1" that I can't figure out. Here are the details.
view code:
<% #students.each do |student| %>
.
.
<td><%= link_to 'Show', student %></td>
<td><%= link_to 'Edit', edit_student_path(student) %></td>
<td><%= link_to 'Select Subjects', select_path(student) %></td> # error occurs here
In my students controller:
def select
.
.
end
routes.rb:
HomeSchool::Application.routes.draw do
resources :notes
resources :assignments
resources :subjects do
resources :assignments, :only => [:create, :index, :new]
end
resources :students
resources :resources
match "students/:id/select" => "students#select", :as => :select
root :to => 'students#index'
end
The output from rake routes is:
GET /students/:id/select(.:format) students/:id#select
notes GET /notes(.:format) notes#index
POST /notes(.:format) notes#create
new_note GET /notes/new(.:format) notes#new

POST /resources(.:format) resources#create
new_resource GET /resources/new(.:format) resources#new
edit_resource GET /resources/:id/edit(.:format) resources#edit
resource GET /resources/:id(.:format) resources#show
PUT /resources/:id(.:format) resources#update
DELETE /resources/:id(.:format) resources#destroy
select /students/:id/select(.:format) students#select
root / students#index
Any suggestions? I'm having a really hard time grasping exactly how routing in rails is supposed to work and I have yet to find any kind of treatise on it but I'm pretty sure that having no method listed for my select route is at least part of my problem.
Thanks,
Lon

Answer 1

Try removing the match in your routes.rb file and change your students resource to this:
resources :students do
member do
get 'select'
end
end
Also update your view to call select_student_path(student).

Answer 2

This happens because of your routes.rb file. It doesn't have a callback for post method in "/students/new"
To correct this.
Go to routes.rb and add post 'students/new' to: 'students#new' before end.
and check rails routes. you will find a routing path there for the post.
