I am doing a step by step web application from the Rails Guide provided by RailsInstaller.org, and I have so far completed
5.12 Using partials to clean up duplication in views. Although, when I got to the delete section of the lesson and completed all the things provided there, a problem took place in my blog application when I click the destroy action in http://localhost:3000/articles,
Listing Articles
| Title | Text | |||

| Hi Nick | How are things going? | Show | Edit | Destroy |
| Doing fine. | And you? | Show | Edit | Destroy |
| Doing fine | As well. | Show | Edit | Destroy |
| anything new | happen? | Show | Edit | |
Instead of executing the Destroy method, it will redirect me to the show method.
Is there any way to debug this problem?
My Rails version is Rails 4.2.5.1 and my Ruby version is ruby 2.1.8p440 (2015-12-16 revision 53160) [i386-mingw32]
Here are some of my .rb .erb and .js files. I was wondering if there are any flaws in my files that someone could call me out on. OK..... Here they are...

end
def create
@article = Article.new(article_params)
if @article.save
redirect_to @article
else

end
end

@article = Article.find(params[:id])
if @article.update(article_params)
redirect_to @article
else

end
end

@article = Article.find(params[:id])

But how? the only temporary solution i could find was to change the link_to method in my index to the button_to method, and even then it wont execute the confirm deletion.

<td><%= link_to 'Edit', edit_article_path(article) %></td>
<td><%= link_to 'Destroy', article_path(article), method: :delete, data: { confirm: 'Are you sure?' } %></td>

Rails uses Javascript to emulate HTTP DELETE (browsers usually support only GET and POST). My guess is that either there is a JS error on your page preventing Rails from converting the link's behavior to DELETE. Open your browser's Dev tools (Ctrl-Shift-I on chrome) and see if there is a JS error.
Another possibility is that the JS isn't loaded on your page. You can view the page's source in the browser to check if there's a script tag pointing to application-____.js. Also, double check if you've disabled Javascript in your browser.

Well, what are the errors? I don't have psychic powers to see what's on your screen halfway across the world lol
A list of the errors or a screenshot would help.
