Routing Error | No route matches [POST] "/subscriptions/create"

Question

I'm new to Ruby on Rails and I'm working on an application that contains form used to create a new nominee ( store it in the database) I get the problem with this instruction of the form:

<%= form_for :subscription, :url => {:controller => "subscriptions", :action => "create"} do |f| %>

this is the error:

Routing Error
No route matches [POST] "/subscriptions/create"

Answer 1

As you can see from the lines below:

Prefix Verb       URI Pattern                               Controller#Action
subscriptions_create GET        /subscriptions/create(.:format)           subscriptions#create

you have got a route for subscriptions_create but it needs to be POST instead of GET. Simply update this route in your routes.rb file in your config folder to be a POST instead of a GET.

Answer 2

As you can see from this line subscriptions_create GET /subscriptions/create(.:format), that route is only available when using GET HTTP method.

You need to change your routes.rb file for subscriptions to accept POST instead of GET. The easiest way would be to add resources :subscriptions, which will add all standard CRUD routes for resource.
