rails 3.1, why devise can't build the resource?
我注意到在
以下是发送的params对象：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | "student"=>{"first_name"=>"George", "last_name"=>"Michle", "company_name"=>"Meri", "work_title"=>"Architect", "address"=>"Moon", "postal_code"=>"23410", "work_phone"=>"", "home_phone"=>"", "mobile_phone"=>"", "fax"=>"", "email"=>"[email protected]", "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]", "country_id"=>"2", "state_province_id"=>"2"} |
以下是结果资源属性：
1 | [["address",""], ["city", nil], ["company_name",""], ["country_id", 1], ["created_at", Wed, 08 Feb 2012 04:52:35 UTC +00:00], ["current_sign_in_at", nil], ["current_sign_in_ip", nil], ["email",""], ["encrypted_password",""], ["fax",""], ["first_name",""], ["home_phone",""], ["last_name",""], ["last_sign_in_at", nil], ["last_sign_in_ip", nil], ["license_number", nil], ["mobile_phone",""], ["postal_code",""], ["remember_created_at", nil], ["reset_password_sent_at", nil], ["reset_password_token", nil], ["sign_in_count", 0], ["state_province_id", nil], ["updated_at", Wed, 08 Feb 2012 04:52:35 UTC +00:00], ["username", nil], ["work_phone",""], ["work_title",""]] |

那么，为什么构建资源不能填充参数？在哪里解决这个问题？任何帮助都将不胜感激。

学生模型如下：

路径文件中的学生模型：
1 2 | devise_for :students, :controllers => { :registrations =>"students/registrations" } devise_for :students, :controllers => { :sessions =>"students/sessions" } |
。
编辑2：
这是学生注册管理员：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | class Students::RegistrationsController < Devise::RegistrationsController def update # no mass assignment for country_id, we do it manually # check for existence of the country in case a malicious user manipulates the params (fails silently) if student_signed_in? then if params[resource_name][:country_id] resource['country_id'] = params[resource_name][:country_id] if Country.find_by_id(params[resource_name][:country_id]) end if params[resource_name][:state_province_id] resource.state_province_id = params[resource_name][:state_province_id] if State.find_by_id(params[resource_name][:state_province_id]) end end super end def create super end end |
我也有类似的问题。在我的创建方法中，构建资源没有使用给定的参数，注册失败。->电子邮件不能为空邮件
问题是我使用的是Designe3.0，这对我很有用：
1 | build_resource sign_up_params |
device<3.0在没有注册参数的情况下运行良好
如果我从学生模型中删除此行：
1 | attr_accessor :email, :password, :password_confirmation, :remember_me |

一切正常！，我不应该添加
嗯，构建资源方法如下：
1 2 3 4 | def build_resource(hash=nil) hash ||= params[resource_name] || {} self.resource = resource_class.new_with_session(hash, session) end |
所以它看起来像是返回了一个从空哈希构建的资源，而这又可能指示一个命名问题。请在Routes档案和学生模型(
