【问题描述】:
我在尝试提交我的 simple_form 时收到此错误:
= simple_form_for(@profile, :url => profile_path, :method => :put) do |f|
= f.error_notification
.container
= f.input :time_zone, :collection => ActiveSupport::TimeZone.all,
:label_method => :to_s, :value_method => :name, :include_blank => false
.actions
= f.button :submit
我已将time_zone 放入可访问属性中:
class Profiles < ActiveRecord::Base
attr_accessible :time_zone
belongs_to :user
end
并将列添加到表中:
class AddTimeZoneToProfile < ActiveRecord::Migration
def change
add_column :profiles, :time_zone, :string, :default => "UTC"
end
end
并运行迁移:
$rake db:migrate
== AddTimeZoneToProfile: migrating ===========================================
-- add_column(:profiles, :time_zone, :string, {:default=>"UTC"})
-> 0.0369s
== AddTimeZoneToProfile: migrated (0.0370s) ==================================
由于某种原因,我得到了批量分配错误。关于这里有什么问题的任何线索?
更新: 这些是随更新请求发送的参数:
{"utf8"=>"✓", "_method"=>"put", "authenticity_token"=>"udKomXmmmOG+7Z4YKR03y9zMg58rnx1EXqE33a+6Shw=", "profile"=>{ "time_zone"=>"Stockholm"}, "commit"=>"Update Profile", "action"=>"update", "controller"=>"profiles"}
谢谢,
【问题讨论】:
-
你在使用 Rails 4 吗?
-
$rails -v Rails 3.2.14 和 ruby $ruby -v ruby 2.0.0p353(2013-11-22 修订版 43784)[x86_64-darwin13.0.0]
-
尝试重启你的服务器
-
谢谢,但重启并没有改善。顺便说一句,我正在使用 WEBrick。

旁白:
class Profiles?那应该是单数:class Profile
