Rails create method to post object not working

I'm new to working with rails. I created a article posting form and when I click the post button it brings me to the articles page but it's not posting what I typed.

routes.rb:

get 'articles/new' => 'articles#new'
  post 'articles' => 'articles#create'

articles controller:

class ArticlesController < ApplicationController
  def index
    @articles = Article.all
  end

  def new
    @article = Article.new
  end

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

  private

  def article_params
    params.required(:article).permit(:content)
  end
end
