Ruby on Rails Devise user

I am new to ruby on rails. I am originally a PHP/mysql programmer. I can not seem to understand how you connect any posts to the user and display them (e.g. a post is successfully created with the user ID and then the users ID is queried to get his or her name.)

I am using devise for authentication.

Controller

def create
  poll = current_user.polls.build(params[:poll])
  poll.onefourty = poll.onefourty[0..140]
  poll.created_at = Time.now
  poll.save!

  if @poll.save
    redirect_to root_path
  else
    redirect_to root_path
  end

end

Form

<%= form_for Poll.new, :html => { :multipart => true } do |f| %>

<div id="form">
  <div class="text_input" style="height: 65px;"><%= f.text_area :onefourty %><div class="label" style="height: 63px; 开发者_StackOverflow中文版line-height: 63px;">Question</div></div>
  <div class="text_input"><%= f.text_field :option1 %><div class="label">Option One</div></div>
  <div class="text_input"><%= f.text_field :option2 %><div class="label">Option Two</div></div>
  <div class="text_input"><%= f.text_field :option3 %><div class="label">Option Three</div></div>
  <div class="text_input"><%= f.text_field :option4 %><div class="label">Option Four</div></div>

  <div id="submit">
 <div id="left">
 </div>
 <%= f.submit :id => "next", :value => "" %>
  </div>
</div>
<% end %>

Assuming you have the following structure:

# app/model/user.rb
class User < ActiveRecord::Base
  has_many :polls
  #...
end

# app/model/poll.rb
class Poll < ActiveRecord::Base
  belongs_to :user
  #...
end

And if you're successfully creating polls, which it appears you probably are, then in any view - you could query and display the current user's polls with:

# app/views/polls/index.html.erb

<%- if current_user -%>
  <%- current_user.polls.each do |poll| -%>
    <h2><%= poll.onefourty %></h2>
    <ul>
      <li><%= poll.option1 %></li>
      <li><%= poll.option2 %></li>
      <li><%= poll.option3 %></li>
      <li><%= poll.option4 %></li>
      <li><%= poll.option5 %></li>
      <li><%= poll.option6 %></li>
    </ul>
  <%- end -%>
<%- else -%>
  <em>Not logged in</em>
<%- end -%>
