试图将数据从表单保存到数据库。使用 select_tag
<%= select_tag :size, options_from_collection_for_select(@plan, 'name', 'size') %>
一切都很好,它同时获取大小和电子邮件,但是当我尝试存储表单(大小)中的数据时,它传递了 NULL。
这是我的控制台:
Started POST "/users" for 127.0.0.1 at 2011-06-24 07:25:29 -0500
Processing by UserController#create as HTML
Parameters: {"utf8"=>"✓", "authenticity_token"=>"MfT3gs5TtR+bvpaLro0E8Qm1zojaY2ms9WK0WprKPAw=", "size"=>"small",
"user"=>{"email"=>"5@gmail.com"}, "commit"=>"Create User"}
AREL (0.4ms) INSERT INTO "users" ("email", "size", "created_at", "updated_at") VALUES
('5@gmail.com', NULL, '2011-06-24 12:25:29.646814', '2011-06-24 12:25:29.646814')
Redirected to http://localhost:3000/users/14
Completed 302 Found in 56ms
因此,它从表单中获取正确的数据,如您所见“size”=>“small”,但是当它存储它时,它将它作为 NULL 传递,
VALUES ('5@gmail.com', NULL, '2011-06-24
我想,这是 select_tag,因为它没有附加你,就像 text_field 一样
<%= form_for @user do |u| %>
<%= render 'shared/error_messages' %>
<p><%= u.label :size, 'How many employees do you have?' %>: </p>
<p><%= select_tag :size, options_from_collection_for_select(@plan, 'name', 'size') %></p>
<p><%= u.label :email, 'What\'s your email address?' %>:</p>
<p><%= u.text_field :email %></p>
<%= u.submit%>
<% end %>
但是当我尝试 u.select_tag = Error, undefined 方法时。
我的模型
class User < ActiveRecord::Base
attr_accessible :size, :email
end
有什么想法吗?
