No route matches [GET] "/recipes/1/like" I want a POST request

Question

I've never encountered this problem before. I'm getting this error.

No route matches [GET] "/recipes/1/like"

Here is my routes.rb:

Rails.application.routes.draw do

  root 'pages#home'

  get '/home', to: "pages#home"

  resources :recipes do
    member do
      post 'like'
    end
  end
end

Here is my recipes_controller:

  def like
    @recipe = Recipe.create(params[:id])
    Like.create(like: params[:like], chef: Chef.first, recipe: @recipe)
    #flash message
    flash[:success] = "Your selection was sucessful"
    redirect_to :back
  end

Here is my html.erb file:

<%= render 'shared/page_title', title: @recipe.name.titleize  %>

<div class= "row">
  <div class="col-md-4 pull-right center">
    <%= gravator_for @recipe.chef, size: 200 %>
    <p>
      <h5>Brought to you by: <%= @recipe.chef.chefname.capitalize %></h5>
    </p>
  </div>
  <div class= "col-xs-8 col-md-8">
    <%= link_to "Edit this Recipe", edit_recipe_path(@recipe), class: "btn btn-success pull-right" %>
    <h3><%= @recipe.summary.capitalize %></h3>
    <div class="show_recipe">
      <%= image_tag(@recipe.picture.url, size: "300x200", class: "recipe-image") if @recipe.picture? %>
    </div>
    <div class ="well recipe-description">
      <p>
        <strong> Steps:</strong>
      </p>
        <%= simple_format(@recipe.description) %>
        <div class="pull-right">
          <%= link_to like_recipe_path(@recipe, like: true), method: :post do %>
            <i class="glyphicon glyphicon-thumbs-up"></i>
          <% end %> &nbsp&nbsp&nbsp&nbsp
          <%= link_to like_recipe_path(@recipe, like: false), :method => :post do %>
            <i class="glyphicon glyphicon-thumbs-down"></i>
          <% end %>
        </div>
    </div>
  </div>
</div>

<h5><%= link_to "Return to Recipes Listings", recipes_path, class: "btn btn-warning btn-small" %></h5>

I've explicitly added the HTTP POST request to my html.erb file

%= link_to like_recipe_path(@recipe, like: true), method: :post do %>

but rails is complaining that there is no GET route request, which I never created in my routes because I need a POST request for this particular section of the web app.

Rake routes:

     Prefix Verb   URI Pattern                 Controller#Action
       root GET    /                           pages#home
       home GET    /home(.:format)             pages#home
like_recipe POST   /recipes/:id/like(.:format) recipes#like
    recipes GET    /recipes(.:format)          recipes#index
            POST   /recipes(.:format)          recipes#create
 new_recipe GET    /recipes/new(.:format)      recipes#new
edit_recipe GET    /recipes/:id/edit(.:format) recipes#edit
     recipe GET    /recipes/:id(.:format)      recipes#show
            PATCH  /recipes/:id(.:format)      recipes#update
            PUT    /recipes/:id(.:format)      recipes#update
            DELETE /recipes/:id(.:format)      recipes#destroy

I am honestly lost. It seems that everything is in its right place.

Rails version:

Rails 4.2.5

I've defined the action, created the like model, nested the route under recipes, and explicitly requested for a post HTTP request in the html.erb page.

Any ideas would be great!

Cheers!

Here's the relevant code from my working project with a similar arrangement.

# /views/events/splits.html.erb:

<%= link_to "Add",
   associate_splits_event_path(id: @event.id, split_ids: [split.id]),
   :method => :put,
   :class => 'btn btn-xs btn-success' %>

# routes.rb

  resources :events do
    member { put :associate_splits }
  end

If it's helpful to see it in context, feel free to poke around the repo. Here's a link to the view: https://github.com/SplitTime/OpenSplitTime/blob/master/app/views/events/splits.html.erb

Try with

<%= link_to "LIKE", like_recipe_path(@recipe) ,  method: :post %>

Other option:

<%= link_to '<i class="glyphicon glyphicon-thumbs-up"></i>'.html_safe , like_recipe_path(@recipe ,  like: 'value' ) ,  method: :post %>

Answer 3

While rails link_to does allow links to make requests with a method other than GET, it is not the normal behavior of links and relies on Javascript to make a form which gets submitted behind the scenes. Rails uses jquery-ujs for this, so make sure you haven't disabled it.

That said, making POST requests is normal behavior for forms, so you could also try using button_to instead, and simply styling the button to look like a link if necessary.

<%= button_to "Like",  like_recipe_path(@recipe), method: :delete, like: true  %>

You need to add a GET route:

resources :recipes do
    member do
      get 'like'
      post 'like'
    end
  end
