Question

I created a form in Rails 3.2 using the format below, but when I open the post view, I don’t see the form to allow me post comments. What could be wrong?

<%= form_tag(:controller => "posts", :action => "create") do %>  
  <%= label_tag(:message, "What are you doing?") %><br />  
  <%= text_area_tag(:message, nil, :size => "44x6") %><br />  
  <%= submit_tag("Update") %>  
<% end %>

Answer 1

In Rails 3 the form_* helpers return the markup rather than outputting it directly. Change:

<% form_tag(:controller => "posts", :action => "create") do %>

to:

<%= form_tag(:controller => "posts", :action => "create") do %>
