从另一个模型注册用户 [英] Registering the user from another model

问题描述

每个用户只能有一个 MedicalHistory 让我有

class User < ActiveRecord::Base
    acts_as_authentic
end

class MedicalHistory < ActiveRecord::Base
    belongs_to :user
end

使用上面我可以成功地创建从 MedicalHistory 模式，在控制台的用户：

Using the above I can successfully create the user from the MedicalHistory model in the console:

newuser = Medicalhistory.new
newuser.user = User.new
newuser.user.username='testusername'
newuser.user.password='blahblah'
newuser.user.password_confirmation='blahblah'
newuser.user.save

MedicalHistory侧面看起来像下面的

MedicalHistory Side looks like following

#controller
def new
    @medicalhistory = MedicalHistory.new
    @medicalhistory.user = User.new
end

#form
<%=...%>
<%=f.intput :cell_phone%>
<%=f.fields_for :user do |builder|%>
  <%= render "registration_form", :f => builder %>
<% end %>

#Partial
<%=f.input :email%>
<%=f.input :password%>
<%=f.input :password_confirmation%>

错误

当提交表单我得到以下错误：

When submitting the form I am getting below error:

User(#-) expected, got ActiveSupport::HashWithIndifferentAccess(#)

错误是以下行：

Error is on following line:

#controller
def create
    @medicalhistory = Medicalhistory.new(session[:medicalhistory_params]) #gives error
    #somewhere here I should extract registration fields and register the user
end

问题 有没有一种方法可以让我避免部分（注册字段）领域进入了会话[：medicalhistory_params] ...有一个除了还是什么？

Question Is there a way I can avoid fields in the partial (registration fields) getting into the session[:medicalhistory_params]...is there a except or something?

推荐答案

更​​改模型如下：

class MedicalHistory < ActiveRecord::Base
  belongs_to :user
  accepts_nested_attributes_for :user
end
