simple_form not saving content

I am trying to create a simple blog app using simple_form

In my new.html.erb for Post, I have the following code

<h3>Write your blog post here</h3>
<%= simple_form_for @post do |f| %>
  <%= f.input :content %><br>
  <%= f.submit %>
<% end %>

In index.html.erb, I got 

<%= @posts.each do |post| %>
  <p>Post: <%= post.content %></p>
<% end %>

However, I am getting the following on my index page for Post

[#<Post id: 1, created_at: "2015-09-07 23:07:54", updated_at: "2015-09-07 23:07:54", content: nil>, #<Post id: 2, created_at: "2015-09-07 23:07:54", updated_at: "2015-09-07 23:07:54", content: nil>, #<Post id: 3, created_at: "2015-09-07 23:08:11", updated_at: "2015-09-07 23:08:11", content: nil>,

Here is my Post Controller

  def index
    @posts = Post.all
  end

  def show
    @post = Post.find(params[:id])
  end

  def new
    @post = Post.new
  end

  def create
    @post = Post.new(params[post_params])
      if @post.save
        success = true
        message = "Nice!"
      else
        success = false
        message = "Sucks!"
      end
      redirect_to root_path
  end

  private

  def post_params
    params.require(:post).permit(:content)
  end
end

Here is my model

class Post < ActiveRecord::Base
  belongs_to :user
end

And finally, the migration to add content column to Post

class AddContentToPosts < ActiveRecord::Migration
  def change
    add_column :posts, :content, :string
  end
end

After typing the text in my Post, I am able to create it. But I am not sure if it's being saved as the content says "nil". This is very frustrating as it seems like a very simple problem. After hours of trying to figure out what's going on, asking for help here... Thank you!

You have two problems:

First, this line:

<%= @posts.each do |post| %>

Needs a <%, not a <%=.

<%= outputs the result of the expression. The result of array.each is an array, and that's what you're seeing the browser.

Second, your accessing of params is wrong. You're using

@post = Post.new(params[post_params])

You use params[:post], or you use post_params, but you don't do both. You're trying to use the return value of post_params, which is an Hash of keys and values, as a key to access params again. You need either of these:

@post = Post.new(params[:post])
# or
@post = Post.new(post_params)
