添加嵌套属性以设计用户模型 [英] Adding nested attributes to devise user model
问题描述
乍看之下,这个问题似乎已经被回答过了,但我的情况却没有(大多数与大规模分配问题和/或蒙古包有关).即使有很多问题,我也找不到答案.相关问题在这里.
At first glance it would seem this question has been answered before, but not on my case (most are related to mass assignment issues and/or mongoid.) I have not been able to find an answer even though there are plenty somewhat related questions here.
因此,基本上,我正在使用devise gem在ruby on rails应用程序上进行用户身份验证,并且我想向用户模型添加嵌套地址模型.我还使用了simple_form来生成表单视图.
So basically I'm using the devise gem for user authentication on a ruby on rails application and I want to add a nested address model to the user model. I'm also using simple_form to generate the form views.
我有一个用户模型:
class User < ActiveRecord::Base
has_and_belongs_to_many :roles
has_one :address
accepts_nested_attributes_for :address, :allow_destroy => true
end
这是地址模型:
class Address < ActiveRecord::Base
belongs_to :country
belongs_to :state
belongs_to :user
attr_accessible :street1, :street2, :country_id, :state_id, :city, :postalCode
end
这是用户"控制器,为了添加显示操作以显示用户个人资料,我将其覆盖.
This is the Users controller, which I overrode in order to add a show action to display user profile.
class Users::RegistrationsController < Devise::RegistrationsController
def new
resource = build_resource({})
resource.build_address
respond_with resource
end
# POST /resource
def create
resource = build_resource(params[:user])
if resource.save
if resource.active_for_authentication?
set_flash_message :notice, :signed_up if is_navigational_format?
sign_up(resource_name, resource)
respond_with resource, :location => after_sign_up_path_for(resource)
else
set_flash_message :notice, :"signed_up_but_#{resource.inactive_message}" if is_navigational_format?
expire_session_data_after_sign_in!
respond_with resource, :location => after_inactive_sign_up_path_for(resource)
end
else
clean_up_passwords resource
respond_with resource
end
end
def show
@user = User.find(params[:id])
#Add to view count if not viewing own user profile
if @user != current_user
@user.views += 1
@user.save
end
@vehicles = Vehicle.where(:user_id => @user)
respond_to do |format|
format.html # show.html.erb
format.json { render json: @user }
end
end
end
这是用于创建新用户的视图:
This is the view for creating new users:
<%= simple_form_for(resource, :as => resource_name, :url => registration_path(resource_name) ) do |f| %>
<fieldset>
<%= f.input :username, :required => false, :autofocus => true, placeholder: 'Pick a username' %>
<%= f.input :email, :required => false, placeholder: 'Your email' %>
<%= f.input :password, :required => false, placeholder: 'Create a password' %>
<%= f.input :password_confirmation, :required => false, placeholder: 'Confirm your password' %>
<%= f.association :roles, :as => :check_boxes, :label => "", :required => false %>
<%= f.simple_fields_for :address do |a| %>
<%= a.input :street1 %>
<%= a.input :street2 %>
<%= a.association :country %>
<%= a.association :state %>
<%= a.input :city %>
<%= a.input :postalCode %>
<% end %>
<%= f.button :submit, 'Sign up for free', :class => 'btn btn-success btn-large' %>
</fieldset>
<% end %>
因此,创建新用户时的错误是: 地址用户不能为空
So the error upon creating a new user is this: Address user can't be blank
基本上没有为地址设置外键user_id.
Basically the foreign key user_id is not being set for address.
我希望有人可以对此问题有所了解.
I was hoping somebody can shed a little light on this issue.
推荐答案
忘记添加user_id来解决迁移问题.当向地址模型添加belongs_to:user时,Rails会期望它.
Forgot to add user_id to address migration. Rails expected it when adding belongs_to :user to the address model.
