Another Rails No route matche [Patch] - ruby-on-rails

Question

I am trying to edit an article and re-save it. I can create a new article and save that. I can even comment on the article and save that. When I go to edit the article it auto populates the form with the text to be edited but when I try to save that it gives me the "No route matches [Patch]"/artices.7" error.
article controller
class ArticlesController < ApplicationController
def index
#articles = Article.all
end
def show
#articles = Article.find(params[:id])
end
def new
#articles = Article.new
end
def edit
#articles = Article.find(params[:id])
end
def create
#articles = Article.new(articles_params)
if #articles.save
redirect_to #articles
else
render 'new'
end
end
def update
#articles = Article.find(params[:id])
if #articles.update(articles_params)
redirect_to #articles
else
render 'edit'
end
end
def destroy
#articles = Article.find(params[:id])
#articles.destroy
redirect_to articles_path
end
private
def articles_params
params.require(:articles).permit(:title, :text)
end
end
comment controller
class CommentsController < ApplicationController
def create
#articles = Article.find(params[:article_id])
#comment = #articles.comments.create(comment_params)
redirect_to articles_path(#articles)
end
def destroy
#articles = Article.find(params[:article_id])
#comment = #articles.comments.find(params[:id])
#comment.destroy
redirect_to articles_path(#articles)
end
private
def comment_params
params.require(:comment).permit(:commenter, :body)
end
end
routes
Rails.application.routes.draw do
resources :articles do
resources :comments
end
end
When I run the edit blog edit.html.erb it gives me "No route matches [Patch] error. Should I do my routes a different way? I thought resources would cover that. Here is the edit file
<h1>Editing article</h1>
<%= form_for :articles, url: articles_path(#articles), method: :patch do |f| %>
<% if #articles.errors.any? %>
<div id="error_explanation">
<h2>
<%= pluralize(#articles.errors.count, "error") %> prohibited
this article from being saved:
</h2>
<ul>
<% #articles.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<p>
<%= f.label :title %><br>
<%= f.text_field :title %>
</p>
<p>
<%= f.label :text %><br>
<%= f.text_area :text %>
</p>
<p>
<%= f.submit %>
</p>
<% end %>

I think I found it, in your form_for declaration you specified articles_path rather than article_path. Those are two different methods and they expect different parameters. Use article_path instead and you should get the expected result.
Also, this doesn't make any difference in terms of the computer processing, but you should name your instance variable #article instead of #articles, because it only refers to one object, rather than a list of objects. As you work with Rails (especially the routes, controller names, model names etc.) you'll keep noticing that the framework is very picky about when you use singulars and when you use plurals, which is of course why you made the mistake of using articles_path as explained above.
Rails makes it even more frustrating because they didn't inform you that you were using the wrong method. articles_path doesn't require an article ID, so ideally Rails would raise an error when you gave it one, but it turns out that all the _path and _url route helper methods accept an additional variable so you can define the file extension of the URL (which you would normally define like article_path(#article, "xml").
