Rails create method to post object not working

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>

Sorry about the articles controller code it wouldn't format right. — Taylor Gagne, Oct 29 '15 at 04:51
Could you please show your form where you have the post button? — K M Rakibul Islam, Oct 29 '15 at 04:58
Can you update the question with the form code and the log generated in the server? — Pavan, Oct 29 '15 at 04:58
you really need to start posting more acceptable questions, that's two in a row. — sevenseacat, Oct 29 '15 at 04:59
Checking the log is your best bet in this case. In your server log you should be able to see what's going on with your request. — K M Rakibul Islam, Oct 29 '15 at 05:03

Unpermitted parameters: title, body

You should change your article_params to below

def article_params
  params.require(:article).permit(:title, :body)
end

I changed it but it still didn't post to the index page? – Taylor Gagne Oct 29 '15 at 05:21

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

Remove the **d** in `required` :) – Pavan Oct 29 '15 at 05:13

it's not supposed to post to the index page, it's supposed to post to the create action. – sevenseacat Oct 29 '15 at 05:22
Does your model have a `content ` column too? then permit that too. Also, change `required` to `require`. `params.require(:article).permit(:title, :body, :content)` see if that fixes the issue. Otherwise, post the server log again in your question section as an update. – K M Rakibul Islam Oct 29 '15 at 05:22
try using route helper `redirect_to articles_path` – Deepak Mahakale Oct 29 '15 at 05:23
is the route supposed to look like this: get 'articles/articles' => 'article#index' – Taylor Gagne Oct 29 '15 at 05:39

It should be: `get 'articles' => 'article#index'` if you don't want to go for the RESTful resource. – K M Rakibul Islam Oct 29 '15 at 05:43
I have the resource in the routes file – Taylor Gagne Oct 29 '15 at 05:51
I tried a post again and it gave me this error message: uninitialized constant ArticleController – Taylor Gagne Oct 29 '15 at 05:56

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
