form_for Update Model

Question

I have the following code which I would like to update the particular object in the database. For some reason however this function will not display. Based on the log reports I am getting back nothing is wrong. Information outside of the code block is returned fine.

<% form_for (@person), :url => {:controller => "persons", :action => "update" } do |f| %>
        <%= f.label :name, "Name" %><br/>
        <%= f.text_field :name %>
        <%= f.label :score, "Score" %>
        <%= f.text_field :score %>
  <%= f.submit("Update") %>
<% end %>

Answer 1

你应该使用<%= form_for ...而不是<% form_for ... （它都在等号中）
