Form Sending To The Wrong PUT Request - ruby-on-rails

Question

I have two models for users ; the Plans model has_many users. Now, what I would like to do is to allow users to upgrade/downgrade their plans, by changing the plan_id. I've set up a form, as well as the appropriate action, but when I hit submit, it doesn't seem to do what the PUT action says. It seems to use the update action.
Here's my form :
<%= form_tag("/users/update_plan", :method => "put" ) do %>
<%= hidden_field_tag :plan_id, plan.id %>
<%= submit_tag("Change To Plan", :class => "signup") %>
<% end %>
Here's my update action
def update_plan
#user = current_user
#user.plan_id = params[:plan_id]
#user.save
sign_in #user
redirect_to change_plan
end
When I submit the form above though, it not only doesn't register the change, but I think it uses the update action, and not the update_plan action. The reason I think this is because it redirects to the what's in the update action, and it flashes the same thing as the update action.
def update
#user = current_user
if #user.update_attributes(params[:user])
flash[:success] = "Profile updated"
sign_in #user
redirect_to edit_user_path(#user)
else
render 'edit'
end
end
Here's my routes.rb file
Dentist::Application.routes.draw do
resources :users
resources :sessions, only: [:new, :create, :destroy]
resources :phones, only: [:new, :create, :destroy]
resources :find_numbers, only: [:new, :create, :destroy]
put 'users/update_plan'
match '/signup', to: 'users#new'
match '/login', to: 'sessions#new'
match '/signout', to: 'sessions#destroy', via: :delete
match '/change_plan', to: 'users#change_plan'
root to: 'static_pages#home'
match '/product_demo', to: 'static_pages#product_demo'
match '/pricing', to: 'plans#index'
match '/contact', to: 'static_pages#contact'
And here's a console screenshot of what's happening:

It seems to say it's using the update_plan action, but... :S
Any help on trying to get Update_plan action to function would be greatly appreciated!

Answer 1

The form is going to the right place (/users/update_plan), but that is being routed to:
UsersController#update
as it says on the second line of your console log. So not the action you expect, and the problem is in your routes. Try this to list all your routes:
rake routes
Probably the users update route (created by resources :users) is catching this first:
PUT /users/:id(.:format) users#update
There are no restrictions on the content of id, and format is optional, so users/update_plan would call users/update with an id of update_plan (in fact you can see that is happening at the edge of your console log screenshot, look for the :id => parameter).
So I would move your custom route to the top of the routes file first above resources :users, and also try change it to direct to the action you want, not sure what a route with no action specified does...
put '/users/update_plan', to: 'users#update_plan'
