Rails guides - No route matches [POST] "/articles/new"

Rails

I was working my way through Rails Guides getting started tutorial
(Getting Started with Rails — Ruby on Rails Guides). Everything was
going well until the end of 5.2 when I was set to make a blog post. Any
help that could be provided would be greatly appreciated.

Here’s the trace:

No route matches [POST] “/articles/new”

Rails.root: /home/gregb/workspace/blog

Here’s the trace:

Presumably, you have: new_article_path in your form_for, but you ought
to have: articles_path

See the routes listing you have below that only has GET for the
/articles/new path and the path which routes to articles#create is a
POST to /articles (same as the GET uses for articles#index)

That seems to work! Thanks so much, Rob!

Note from a Ruby newbie. The reason I missed the articles_path option in the form is because I accidentally skipped the " Edit the form_with line inside app/views/articles/new.html.erb to look like this:" line on accident and didn’t update the form to <%= form_with scope: :article, url: articles_path, local: true do |form| %>

Moral of the story: Read the instructions thoroughly.
