Rails create method to post object not working - ruby-on-rails

Question

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.rb:
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
`articles/new.html.erb`:
<div class="create">
<div class="container-fluid">
<%= form_for #article do |t| %>
<%= t.text_field :title, :placeholder => 'Title', :class => 'article_title' %>
<%= t.text_area :body, :placeholder => 'Article', :class => 'article_body' %>
<%= t.submit 'Post', :class => 'btn-btn-article' %>
<% end %>
</div>
</div>

Answer 1

So, your server log is telling you the problem:
Unpermitted parameters: title, body
You have to whitelist your title and body attributes as Action Controller parameters are forbidden to be used in Active Model mass assignments until they have been whitelisted.
Change:
def article_params
params.required(:article).permit(:content)
end
To:
def article_params
params.require(:article).permit(:title, :body)
end
Also, take a look at the official Rails documentation for Strong Parameters
Update
I would suggest you to use RESTful route in your routes file:
resources :articles
Then, you will have this route:
articles GET /articles(.:format) articles#index
Then, in your controller's create action, you can use articles_path:
def create
#article = Article.new(article_params)
if #article.save
redirect_to articles_path
else
render 'new'
end
end

Answer 2

Unpermitted parameters: title, body
You should change your article_params to below
def article_params
params.require(:article).permit(:title, :body)
end

Answer 3

It says in your log -
Unpermitted parameters: title, body
Change your article_params method to
def article_params
params.require(:article).permit(:title, :body, :content)
end
