Rails 5 submit data through a link

I would like to submit information from my views using a link_to orders controller which I'm not sure how to code.

My models

class User < ApplicationRecord
  has_many :orders
  has_many :stocks, through: :orders
end

class Order < ApplicationRecord
  belongs_to :user
  belongs_to :stock
end

class Stock < ApplicationRecord
  has_many :orders
  has_many :users, through: :orders
end

The way to make orders from the rails console is

order = Order.new
user = User.last
stock = Stock.last
final = user.orders.create(user_id: user.id, stock_id: stock.id)

Routes

Rails.application.routes.draw do
  devise_for :users
  devise_for :admins
  get '/history', to: 'orders#history'

  post '/stocks/:id/', to: 'stocks#order', as: 'order_stock'

  resources :stocks
  root 'stocks#index'
end

I would like to have a single link from app/views/stocks/show to submit orders

Help with the link and controller actions would very appreciate it. Thank you in advance

Since you are about to create a new order object; so using POST as a HTTP method would sound more appropriate. So,

link_to "Order Now!", order_stock_path(params[:id]), method: :post

should work I guess.

See this for more info

In stocks_controller

def order
  stock = current_user.stocks.find(params[:id])
  stock.order.create
  redirect_to stock_path(params[:id]), notice: 'Order created'
end

It should look somewhat this

Note: Rails will send an AJAX POST call to the controller in this case; on success it will redirect accordingly. AJAX code will be embedded near the code to the link. See in the browser your self.
