我有一個用一個簡單的模型,用戶一一對應關係和型材型號:使用.build方法通過1to1協會創建
模型/用戶
class User < ActiveRecord::Base
authenticates_with_sorcery!
attr_accessible :email, :password, :password_confirmation
has_one :profile, :dependent => :destroy
validates_presence_of :password, :on => :create
validates :password, :confirmation => true,
:length => { :within => 6..100 }
email_regex = /\A[\w+\-.][email protected][a-z\d\-.]+\.[a-z]+\z/i
validates :email, :presence => true,
:format => { :with => email_regex },
:uniqueness => {:case_sensitive => false},
:length => { :within => 3..50 }
end
型號/配置文件
# == Schema Information
#
# Table name: profiles
#
# id :integer not null, primary key
# weight :decimal(,)
# created_at :datetime
# updated_at :datetime
#
class Profile < ActiveRecord::Base
attr_accessible :weight
belongs_to :user
end
我這樣做是因爲我希望用戶能夠隨着時間的推移跟蹤體重以及在配置文件中存儲其他更多靜態數據(如高度)。
但是,我的新建和創建方法似乎沒有正常工作。我在提交新動作我得到這個錯誤:
undefined method `build' for nil:NilClass
profile_controller
class ProfilesController < ApplicationController
def new
@profile = Profile.new if current_user
end
def create
@profile = current_user.profile.build(params[:profile])
if @profile.save
flash[:success] = "Profile Saved"
redirect_to root_path
else
render 'pages/home'
end
end
def destory
end
end
和新
<%= form_for @profile do |f| %>
<div class="field">
<%= f.text_field :weight %>
</div>
<div class="actions">
<%= f.submit "Submit" %>
</div>
<% end %>
