    <% @post.errors.full_messages.each do |msg| %>
  • <%= msg %>
    • <% end %>
<% end %>
<%= f.label :title %>
<%= f.text_field :title %>
<%= f.label :body %>
<%= f.text_field :body %>
<%= f.label :publish_on %>
<%= f.date_select :publish_on %>
<%= f.label :featured %>
<%= f.check_box :featured %>
<%= f.submit %>
