試圖將表單中的數據保存到數據庫。 使用select_tag從select_tag保存數據
<%= select_tag :size, options_from_collection_for_select(@plan, 'name', 'size') %>
一切都很好,它抓住規模和電子郵件,但是當我嘗試將數據從形式(大小)存儲,它傳遞NULL。
這裏是我的控制檯:
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"=>"[email protected]"}, "commit"=>"Create User"}
AREL (0.4ms) INSERT INTO "users" ("email", "size", "created_at", "updated_at") VALUES
('[email protected]', 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
所以,它從形式得到正確的數據,當你看到「大小」 =>「小」,但是當它的時間來存放它,它並將其作爲NULL,
VALUES ('[email protected]', NULL, '2011-06-24
我想,這是select_tag,因爲它具有u連接的犯規,因爲text_field確實
<%= 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 %>
但瓦特母雞我試過u.select_tag =錯誤,未定義的方法。
我的模型
class User < ActiveRecord::Base
attr_accessible :size, :email
end
有什麼想法?
